How To Determine Calories For Weight Loss


Counting calories : Get back to weight - loss basics

Your weight is a balancing act, and calories play a big role. Find out how calories determine your weight and ways you can best cut calories from your diet. Calories: Fuel for your body. Calories are the energy in food. Your body has a constant demand for energy and uses the calories from food to keep functioning. Carbohydrates, fats and proteins are the types of nutrients that contain calories and are the main energy sources for your body. Regardless of where they come from, the calories you eat are either converted to physical energy or stored within your body as fat. These stored calories will remain in your body as fat unless you use them up, either by reducing calorie intake so that your body must draw on reserves for energy, or by increasing physical activity so that you burn more calories. Your weight is a balancing act, but the equation is simple: If you eat more calories than you burn, you gain weight. Also, because of changes that occur in the body as a result of weight loss, you may need to decrease calories further to continue weight loss. Cutting calories. Balancing calories. more...



How to Determine the Number of Calories You Should Eat to

How to Determine the Number of Calories You Should Eat to Lose Weight. Many people turn to a calorie calculator, but they can greatly overestimate the amount of food that you need to lose weight. From a broad perspective, the basics of weight loss and weight gain are straightforward: when you eat more calories than you use (in which case you’re in a “caloric surplus”) you gain weight. Conversely, when you use more calories than you eat (in which case you’re in a “caloric deficit”) you lose weight. So, in order to stay the same weight, you want to find your “caloric maintenance”: The area where the calories you consume equal the calories you use. There are two ways that you can determine your caloric maintenance. However, if you’ve used calorie calculators before, you may have noticed that they can grossly overestimate the amount of calories that you need to eat daily in order to lose weight. The caveat here is that the very act of writing down what you eat will change your actions , but do your best to eat normally. If you’ve been losing or gaining weight recently, then your calorie log might not be the best method of predicting your caloric “maintenance,” since you might have been in a caloric surplus or deficit. On the other hand, if you feel like you’ve done an excellent job and the calculator is off, err towards your logged averages. Once you figure out your caloric maintenance, it’s time to calculate two things: the amount of protein and the number of calories that you’ll be eating. Protein is important, because it will allow you to keep your lean body mass (and thus your metabolism) high in a caloric deficit. Take your maintenance calories from the previous step and subtract 20% from it. Having a solid set of calorie and protein targets, however, will do wonders for starting you off on the right foot. more...



How Many Calories Do I Need Each Day

Knowing how many calories you need to consume each day is essential for losing - or gaining - weight. Get out your calculator and use the Harris-Benedict formula. The Harris-Benedict formula is used to determine your basal metabolic rate (BMR), which is also called the resting energy expenditure (EER). Your basal metabolic rate is determined by your gender, age and body size, and calculating this number tells you how about how many calories you burn just being alive and awake. You can determine your active metabolic rate (AMR) by multiplying your BMR by a number representing on your activity levels. Calculate your active metabolic rate by starting with your basal metabolic rate and adjusting it by estimating your current level of activity. Lightly active (light exercise/work 1-3 days per week) - your AMR = BMR x 1.375. Moderately active (moderate exercise/work 3-5 days per week) - your AMR = BMR x 1.55. Very active (hard exercise/work 6-7 days a week) - your AMR = BMR x 1.725. Extra active (very hard exercise/work 6-7 days a week) - your AMR = BMR x 1.9. Your AMR should represent the number of calories you need to consume each day to stay at your current weight. Calculate your daily caloric need, and if you don't lose or gain weight, adjust your daily calorie count goal down (or up). more...

Counting Calories to Lose Weight

Most diet plans make eating right seem like a numbers game: Consume X calories and add Y exercise, and you will reach Z ideal weight. Could all that counting, calculating, and measuring be the wrong way to go about it? "Knowing the number of calories you're consuming can help you figure out how much you should eat to reach your weight-loss or maintenance goals," says Elisa Zied, R. And once you get over the shock that you're downing hundreds more calories than you thought and that your go-to frozen dinner is actually two servings, you can adjust your intake so it's more appropriate. Tallying your calories also emphasizes the quantity of calories, rather than the quality of your foods. "Your effort is much better spent focusing on the nutritional value of foods rather than on an endless race between your mouth and the treadmill," says Darya Rose , Ph. If you eat 1,000 calories of refined carbs but stay below your calorie limit for the day, you're not doing your body any favors. Plus research shows that the magic number you arrive at can lead to all-or-nothing mentality. "If you ‘screw up' at one meal, you may think, ‘What the hell, I may as well go crazy today and start over tomorrow.'" Furthermore, counting alone doesn't teach you much of anything except whether you were "under" or "over" that day, and that can lead to guilt and obsession. If you're not going to count calories, there are still ways to be sure you're eating appropriately for your weight goals. (Think about 1 cup raw spinach compared to 1 cup cooked rice or butter.) And research shows that we tend to eat about the same weight of food at meals, so piling on raw veggies instead of macaroni and cheese will satisfy you for fewer calories. more...



Calorie Calculator

The Calorie Calculator can be used to estimate the calories you need to consume each day. You need 2,361 Calories/day to maintain your weight. To loss 1 pound, or 0.5kg per week, you will need to shave 500 calories from your daily menu. Try not to lower your calorie intake by more than 1,000 calories per day, and try to lower your calorie intake gradually. How Many Calories Do You Need? Nearly all of us seek to lose weight, and often the best way to do this is to consume a lower amount of calories each day than we usually do. For example, if you are not very active, your needed calorie intake is the basal metabolic rate times 1.2. The longer you chew your food, the greater the amount of calories you absorb, a recent study has shown. Scientists have recently discovered that there is a difference in terms of gaining or losing weight in the quality of the calories you consume, not just the quantity. Choose snacks carefully, and count the calories you are putting into your snacks. more...



Finding a Balance - Healthy Weight - DNPAO

Weight management is all about balance—balancing the number of calories you consume with the number of calories your body uses or "burns off." To remain in balance and maintain your body weight, the calories consumed (from foods) must be balanced by the calories used (in normal body functions, daily activities, and exercise). "in balance." You are eating roughly the same number of calories that your body is using. "in caloric excess." You are eating more calories than your body is using. If you are maintaining your current body weight, you are in caloric balance. To learn how many calories you are currently eating, begin writing down the foods you eat and the beverages you drink each day. The site will give you a detailed assessment and analysis of your current eating and physical activity habits. Physical activities (both daily activities and exercise) help tip the balance scale by increasing the calories you expend each day. If you eat more than one serving, you'll be eating more calories than is listed on the food label. It's the overall number of calories you eat and the calories you burn over the course of 24 hours that affects your weight. A: While physical activity is a vital part of weight control, so is controlling the number of calories you eat. If you consume more calories than you use through normal daily activities and physical activity, you will still gain weight. more...



Chris Powell’s Custom Weight - Loss Blueprint - The Dr. Oz Show

Here fitness expert Chris Powell shares the secret blueprint you can use to help you feel good and drop unwanted pounds. The bad news is, healthy eating alone won’t necessarily help you drop to your desired weight. The key to successful weight loss is to customize your diet by targeting your body’s specific calorie needs. Metabolism is the process by which your body converts what you eat and drink into energy. The number of calories your body uses to carry out these basic functions is known as your basal metabolic rate – what you might call metabolism. Take your current weight and multiply it by 12 to come up with your “burn rate.” That would mean your body burns 1980 calories a day at its resting metabolic rate. Whenever you eat more calories than your metabolism burns, your body stores the extra energy as body fat. So, in this example, if your normal burn rate is 1980 calories a day and you eat 2500 calories, that means 520 calories are going to extra weight. If you eat 1980 calories, you’ll maintain your weight. And if you eat less than 1980 calories, your body makes up the energy shortfall by tapping into your fat, causing you to lose weight. Now that you know your body’s blueprint and basal metabolic rate, you have a powerful tool to help you lose weight. more...



How To Determine Your Daily Calorie Requirement For Weight

How To Determine Your Daily Calorie Requirement For Weight Loss. For me (and many others), this is not enough calories to thrive on.  Many of us have been conditioned to believe that eat less and lose weight, but sometimes eating more can help you lose weight too!  Remember, use this as a guide and adjust it as you learn to listen to your bodies language. I know, you probably have read that you need to reduce your calorie intake by 500 calories a day to lose 1 pound a week…well that is just plain wrong. If you are still hungry while eating this amount of calories, then you need to eat more. I can assure you that I probably had a similar response to this number, that has to be to many calories to lose weight… Again, you don’t want to count your calories long term.  Try counting your calories for 3 weeks so you can get a feel of how much food is good for you.  Remember, this is just to give you a feel for how many calories you should be eating to lose weight. So give yourself 3 weeks and count calories so you can have a clear idea of how much food that you should be eating. Once you get a feel for it, and you start to lose some weight, then taper off the calorie counting and trust yourself and that you know how to read your bodies language.

BMR Calculator for Weight Loss - Exercise 4 Weight Loss

You will be presented with the calories per day based on the input information. BMR is the amount of calories you would burn while at rest. The second result is the amount of calories you need in order to maintain your current weight based on your activity level. The more active you are the more calories you will require. This is because you are already burning the calories you need in order to sustain life. So if you add activity to this, you need to increase the amount of calories you consume to maintain your weight. If you are trying to lose weight, then you need to reduce your calories. If you reduce the calories you eat, or increase the calories you burn by 500 each day, this would approximate to 1 pound loss for the week. So in order to keep the weight off, you want to lose it slowly. This will help you develop lasting lifestyle changes that will help ensure the weight stays off. more...



What is the weight - loss equation? - Weight Loss

If you consume more calories than you burn, you gain weight. The number of calories you eat to accomplish this needs to be approximately 250 to 1000 calories less than your daily calorie burn. To lose weight you must burn more calories than you consume. If you have a calorie deficit, you will be losing weight, and you must burn an extra 3500 calories (in excess of what you eat) to lose a pound. The weight loss equation IS: BURN MORE CALORIES THAN YOU EAT! Burn more calories than you consume and you will lose weight. Burn less calories than you consume and you will gain weight. Burn the same amount of calories as you consume and you will maintain your weight. To lose weight, you need to consume fewer calories than your body needs per day or use more calories through physical activity and increased metabolism. So if your deficit is 500 calories per day times 7 days you will lose 1 pound of fat. more...



Defining Your Personal Weight Loss Plan - Your All - in

The intent of this step is to determine the weight loss approach that you will implement to begin losing weight. Nutritional Diet Approach - The nutritional diet approach hinges on the concept that all weight loss will be determined by the caloric deficit created by simply consuming less calories than the body physically burns in a day. For example, an individual has determined that the average number of calories that their body burns in a day is 1,725 calories (i.e. Next, they would decide to monitor their caloric intake and limit the total number of calories consumed per day to 1,225. This approach would create a scenario in which the individual would have a caloric deficit of 500 calories per day. By multiplying the caloric deficit of 500 calories per day times seven days in a week, the 3,500-calorie deficit required to lose one pound of body weight would be achieved. Exercise Approach - The exercise approach hinges on the concept that all weight loss will be derived from the additional calories that will be burned through performing physical activities (e.g. For instance, an individual has determined that the average number of calories that their body burns in a day is 1,725 calories (Calculated their TDEE in Step 2). The individual would have a surplus of 175 calories per day, or 1,225 calories per week. In order for an individual to lose one pound per week, they would need to burn the 3,500 calories needed to lose one pound of body weight plus the 1,225 surplus calories that they are storing as body weight due to the fact that they are consuming more calories on a daily basis than their body burns. Hence, the total number of calories they would need to burn through a physical exercise routine in order to lose one pound of body weight per week would be 4,725 (3,500 calories plus the 1,225-calorie surplus). If the individual was able to burn an additional 4,725 calories per week, they would indeed lose 1 pound of body weight per week. The nutritional diet portion of their weight loss program is intended to monitor their caloric intake and limit consumption to 1,225 calories per day. The exercise portion of their weight loss program is intended to burn 1,200 additional calories per week. In this example, an individual would now create a caloric deficit of 4,700 calories per week (3,500 calories from the nutritional diet portion and 1,200 calories from the exercise portion). more...

You can also choose BMR (Basal Metabolic Rate) in the Exercise level. This is effectively the amount of energy expended per day. The calculator currently uses the formula proposed by MD Mifflin and ST St Jeor1. 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) + 5. 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) - 161. This can be selected on the calculator. It is a variation1 on the basic Mifflin-St Jeor equation that will base the equation on Fat Free Mass (FFM) or Lean Mass. This provides us with maintenance calories - the amount of calories you could consume each day and neither lose or gain weight. To get the fat loss figure - 20% of calories is subtracted. The extreme fat loss figure has 40% subtracted. However - there is a "rock bottom" figure that equates to 8 calories per pound of body weight - the extreme fat loss will never be less than this amount. more...



Calories Per Day Calculator for Adults

These adult daily calorie calculator charts give an approximation of the calories per day burned by a moderately-active person. Then a factor is added for the calories you burn in moderate activity. The calorie number shown are the number you could eat per day to maintain your current weight. If you are sedentary , getting no exercise and fewer than 3000 steps per day on your pedometer , you would burn 300 to 400 fewer calories per day than what is shown. When you are dieting, do not go below 1200 calories per day unless you are on a medically supervised weight loss program or after consultation with your doctor. more...



How to Calculate the Calories for Weight Loss

How to Calculate the Calories for Weight Loss. If calories burned are greater than calories consumed, you will lose weight. If calories burned are less than calories consumed than you will gain weight. As an example, if the male from the example lightly cycled for an hour, he would add approximately 422, resulting in a total of 2,140 calories burned in that day. Tally all the calories consumed during the day and add them together. As an example, if you ate three meals totaling 800, 600 and 600 calories, respectively, then your total calories consumed would be 2,000. If the result is a negative number, then you are on the road to weight loss. If the number is positive, then you need to adjust your eating habits and/or activity to create a deficit, because continuing as you are will cause weight gain. In the male example, you would subtract 2,000 from 2,140, resulting in -140, a calorie deficit. If you tracked your calories for a whole week, you would add all the figures and divide by seven. This means that on average, you are losing 200 calories per day. If the average you had calculated was a positive number, then this would be your rate of weight gain. more...



Calorie Calculator - Daily Caloric Needs

It teaches dieters how to calculate their calorie needs (just like our calculator does above) as well as how many grams of carbs, fat, and protein (macros) they should be eating each day for weight loss. No foods are off limits as long as they fit your daily macro amounts and people enjoy the freedom flexible dieting gives them while still experiencing results. To accurately determine your daily calorie amount above, enter your current weight, age, height, and gender into the calculator. The results will show how many calories you may eat in order to maintain or lose weight . You don't need to adjust this depending on your exercise rate - that is factored into the equation. Calories for Fat Loss. Science tells us that 1 pound of fat is equal to 3500 calories, so a daily calorie deficit of 500 should result in 1 pound per week fat loss. The amount of food intake that once resulted in weight loss, will now only maintain 2 . Health authorities do set some baselines - these are 1200 calories per day for women, and 1800 calories per day for men. Metabolic rate will begin to drop (typically) after 3 days of very low calories - this is related to, and compounded by the loss of muscle mass. With very low calories you risk sluggishness, nutritional deficiencies, fatigue, and often irritability. As your exercise level was already factored into the equation, there is NO NEED to subtract calories burned by exercise. We encourage you to include exercise in your lifestyle change: it helps to maintain muscle when under calorie deficit, and it's great for your heart and mental state. more...



Net Calories Needed After Exercise to Lose Weight

Net Calories Needed After Exercise to Lose Weight. Despite the advertising and claims from supplements and fad diets, weight loss requires burning more calories than you consume. Your net calories burned means how many more calories you burn than you eat in your food. Calculate the net calories burned to determine how much weight you will lose and to design an optimal diet and exercise regimen for your weight loss goals. Calories and Weight Loss.

The amount of calories you burn during exercise depends on your weight and your level of activity. The sum of all the calories in all the foods you eat is the number of calories consumed for the day. The calculator tells you how many calories you burned based on the activity you did, the time spent and your weight. To determine net calories, subtract the calories you burned from the calories you took in. If you get a negative number, you burned more calories than you took in and you will lose weight. more...



Metabolism and weight loss : How you burn calories

Metabolism and weight loss: How you burn calories. Find out how metabolism affects weight, the truth behind slow metabolism and how to burn more calories. And if so, is it possible to rev up your metabolism to burn more calories? Although your metabolism influences your body's basic energy needs, it's your food and beverage intake and your physical activity that ultimately determine how much you weigh. Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function. The number of calories your body uses to carry out these basic functions is known as your basal metabolic rate — what you might call metabolism. As you get older, the amount of muscle tends to decrease and fat accounts for more of your weight, slowing down calorie burning. Your basal metabolic rate accounts for about 70 percent of the calories you burn every day. For the most part, your body's energy requirement to process food stays relatively steady and isn't easily changed. Physical activity and exercise — such as playing tennis, walking to the store, chasing after the dog and any other movement — account for the rest of the calories your body burns up each day. Physical activity is by far the most variable of the factors that determine how many calories you burn each day. Metabolism and weight. It may be tempting to blame your metabolism for weight gain. more...

And has 34% body fat will not lose weight on 3000 calories per day (255 X 13 as per the "quick" formula for fat loss). BMR is the total number of calories your body requires for normal bodily functions (excluding activity factors). Your BMR is 1339 calories per day. Your BMR = 370 + (21.6 X 43.6) = 1312 calories. To lose weight, you need to create a calorie deficit by reducing your calories slightly below your maintenance level (or keeping your calories the same and increasing your activity above your current level). Your calorie deficit to lose weight is 500 calories. Your optimal caloric intake for weight loss is 2033 - 500 = 1533 calories. Example 2: Your calorie deficit to lose weight is 20% of TDEE (.20% X 2033 = 406 calories) Your optimal caloric intake for weight loss = 1627 calories. Your optimal caloric intake for weight gain is 2033 + 305 - 406 = 2338 - 2439 calories.

Calories and Macros Calculator : How to

Calories and Macros Calculator: How to Calculate For Fat Loss or Muscle Gain. This is essentially your maintenance calories, the amount of calories YOUR body burns based on the measurements and activity level that you enter in. From there, it then shows your target calories that you should consume depending on your goal (-20% calorie deficit for fat loss, and +20% calorie surplus for muscle building). The resulting macro numbers are your protein, carb, and fat daily targets. The only way to lose fat is to be in a calorie deficit (expending more calories than you consume), and the only way to pack on muscle is to be in a calorie surplus (consuming more calories than you expend). When it comes to counting calories for your fitness goals, it’s also important that you are consuming the right amounts of macronutrients (protein, carbs, and fats) for optimal results. To figure out how much of your calorie intake is coming from carbs, you would simply eat your remaining number of calories after protein and fat have been added together. Step 2: Figure out your protein and fat requirements. Carb Intake = Total Calories – Protein Calories – Fat Calories. Therefore –> 1,900 total calories – 536 protein calories – 603 fat calories = 761 carb calories. Once you figure that out, you will then adjust your daily calorie intake depending on your goal — eat less calories for fat loss, or eat more to bulk up. The amount of fats and carbs that you eat will mainly depend on your personal preference. So if you like carbs, eat more of that and less fat. more...

Weight Loss 101 : How to Calculate a

The result of this calculation is the average number of calories you burn through exercise daily. The result is an estimate of the number of calories you burn in 24 hours outside of exercise. To do this, take your estimate of calories burned at rest and divide it by 24, then multiply the result by the number of hours per day that you do not spend working out. In this case, your daily calories burned at rest is (2,000 calories per day ? 24 hours per day x 23 hours a day you do not work out = 1,916 daily calories burned. To determine the total number of calories you burn daily, add together your average daily exercise calories burned and your calories burned at rest. So, if you burn 1,916 calories per day at rest and 600 calories per day through exercise, then the total number of calories your body burns per day on average is 2,516. This number also represents the total number of calories you would need to consume daily to maintain your current weight. more...



NOVA - Official Website - Is a Calorie a Calorie

Yet some scientists still debate whether all food calories are the same. Does a piece of chocolate have the same effect on weight gain or loss as the exact same number of calories from an orange? The debate boils down to whether all sources of calories are the same for maintaining body weight. Are derived from Atwater values, a century-old way to measure the usable calories in foods. That is, we burn more calories while metabolizing protein than while metabolizing the other two so-called macronutrients. "It is therefore obvious," they wrote in the journal Metabolism, "that the significant factor responsible for weight loss is reduction of calories, irrespective of the composition of the diet." Taking a different approach, a 2012 study reported in the Journal of the American Medical Association concluded that the body may indeed use calories from low-carb diets less efficiently than those from low-fat diets, with greater weight loss as a result. The investigators did not determine the source of this energy loss, but their results implied that very-low-carb diets resulted in more calories wasted in metabolism. (Although subjects consuming the very-low-carb diet expended the most energy, other metabolic measurements taken during this study suggested that low-glycemic index diets are healthiest for maintaining long-term weight loss.) From our reading of the research, we conclude that, while the precise nature of the relationship between diet composition and weight maintenance needs more research, the number of calories consumed relative to those expended matters more to weight loss than where the calories come from. more...



The Truth About Calories, Macronutrients

Its only concerns are the elements of nutrition that are irrefutable and omnipotent in every single diet on that list: calories and nutrients. For this reason, calories are the most important factor in body recomposition. There are some people who argue that calories don’t matter and that the hormones that our bodies produce are the main cause of weight gain or loss. Your BMR is the total daily amount of calories you burn by quite literally being alive. Different macronutrients are processed and utilized differently by the body and require different amounts of energy (calories) to do so. This means that 20-30% of the calories you consume from protein get used up just in the digestion process. The best analogy to help think of and understand the interplay of calories and macros, and one we’ll be referring to throughout, is that of a house. It means that 5% of the total calories consumed from carbohydrates are used up by your bodies processing of them) As you can see in the fat stats below, fat contains more than twice as many calories per gram as protein and carbohydrate, which is why low-fat diets are so effective.

Losing weight is simple and it works like this: If you consume more calories than you burn you store the extra energy as fat . It's very simple and it works like this: If you consume more calories than you burn you are in a "positive energy balance." When you are in a positive energy balance you will store the extra energy as fat, no matter what source the energy is from- protein , carbohydrates , or fat . Carbohydrates also have a protein sparing effect, which keeps the body from burning protein for energy. The main difference between simple and complex carbohydrates is the time it takes for the body to convert them into glucose. One thing to realize is that once the carbohydrates you have eaten have been converted to glucose, what is not used to fuel body functions and replenish muscle glycogen is shuttled into fat stores. So the variable is carbohydrates, if protein and fat intake remain the same each day. When your intake of carbohydrates is low, your body is forced to use stored body fat for energy. When these are present in the blood your body does not have enough carbohydrates available in order to properly metabolize body fat. Without carbohydrates available in the body, your body breaks down protein for additional energy (state of catabolic). Your body will actually metabolize muscle tissue for energy at about the same rate as fat if you do not have a high enough protein intake. The correct way to carb cycle is to make sure you are taking an adequate amount of protein and not limiting your carbohydrates to the point of ketosis. If you continue to have low carb days, your body will eventually adapt to this and slow it's metabolism down to compensate for the lower caloric intake. After that day, you will again feel full of energy, more alert and ready to go into the next three days. If you are getting close to your desired body fat, you may want to cut back to two low carb days and one high carb day. Carbohydrates are the variable when it comes to fat loss. more...



Weight Loss 101 : How to Calculate a Calorie Deficit

To lose weight, you have to eat fewer calories than your body burns each day. How do you know if you're actually eating fewer calories than your body burns? And how can you make sure you're hitting the mark? The Calorie Deficit Sweet Spot. The calorie deficit "sweet spot" for athletes is 300 to 500 calories per day. To do that you need to figure out how many calories you burn each day and then subtract your target deficit of 300 to 500 calories from that number. To begin, add up the total number of hours you train in a typical week and divide that number by seven to yield the average number of hours you train daily. Next, multiply this number by your body weight in pounds and the average number of calories you burn per pound of body weight per hour of training. The average number of calories you burn per hour of training is influenced by your speed. more...



Exercise and Weight Loss - It takes more

The truth is, exercise is a complicated business and there are a number of things that can affect how many calories you burn. How Many Calories Are You Really Burning with Exercise ? If you’re trying to lose weight with exercise , you may have used an activity calculator to determine how many calories you’re burning. For example, if you’re 165 lbs and you go jogging for 30 minutes, this calculator shows you’ve burned about 371 calories. What you can do: If you’re tracking calories burned with exercise, you’ll get a more accurate number by subtracting the calories you would’ve burned if you weren't working out. For example, if you burned 200 calories while walking for 20 minutes and would've burned 50 calories if you sat at the computer during that time, your net calories burned would be 150. You can calculate your calories with this activity calculator . How hard you work plays a role in how many calories you’re burning. The problem is, this assumes you burned exactly 2,000 calories each week and that 6 pounds of fat would generate exactly 6 pounds of body weight loss, which isn’t always the case. What you can do: The formulas we use to calculate exercise intensity and calories burned aren't 100% accurate. Varying your intensity: The harder you work, the more calories you burn, but if all your workouts are high intensity , you run the risk of overtraining and injury. Many monitors also show calories burned during your workout and you can use that number to compare different workouts and different intensity levels . more...



How to Calculate How Many Calories You REALLY Need

How to Calculate How Many Calories You REALLY Need. Instead, go with this formula, a simplified version of what many nutritionists use for their clients: “Multiply your weight in pounds by 12 or 15—12 if you’re mostly sedentary or mildly active and 15 if you do some kind of moderate or high-intensity exercise almost every day,” says New York City nutritionist Brittany Kohn, R. It sucks, but it’s true: As you get older, your metabolism slows a bit, and your system requires fewer calories to function. Now you know how many calories you need to maintain your current weight. Consuming 500 fewer calories per day gives you a deficit of 3,500 calories a week, which equals about one pound, says Kohn. (You can also ramp up your workouts to burn off calories if you find it tough to cut 500 calories from your daily meal plan.) And if you want to gain weight, tack on 250 to 500 extra calories in healthy, whole foods per day. more...



How to Calculate Your Caloric Needs and Lose Weight

How to Calculate Your Caloric Needs and Lose Weight. Do you know how many calories you should eat if you want to lose weight? To estimate how many calories you should consume  to maintain your weight, you'll need to do a little math. If you are sedentary or mostly sedentary multiply your BMR by 1.0-1.39  If you are lightly active (you do 30-60 minutes of easy physical activity each day), multiply your BMR by 1.4-1.59. If you are moderately active (you do 60 minutes of moderate physical activity each day) multiply your BMR by 1.6-1.89. If you are very active multiply your BMR by 1.9-2.5.  The result of this formula will be a good estimate of the number of calories you can eat every day to maintain your current weight. In order to lose weight, you must eat fewer calories than your body needs so that your body burns fat for fuel.  So how do you know how many calories to cut?  The number depends on how quickly you want to lose weight. For every 3,500 calories you cut, you are likely to lose about one pound.  So, if you cut 500 calories per day, you should lose about one pound per week. Your weight loss will vary from week to week and at times you may even gain a little weight. more...



Calculate Recommended Daily Calorie Intake for Weight Loss

Your Recommended Daily Calorie Intake for Weight Loss. The recommended daily calorie intake for weight loss varies depending on the age, sex, activity level, and size of your body. Step 1: How many calories a day you need to maintain your current weight and your current BMI. Step 2: How many calories per day you will need when you reach your target weight and your target BMI. Step 3: What is your recommended daily calorie intake to lose weight. Use the daily calorie calculator to check “Your Average Daily Calorie Need is” - This is the amount of calories you need every day for your activity level to maintain your current weight. Emily’s Average Daily Calorie Need is: 1695 calories or kcal – the number of calories she needs each day to maintain her current weight of 160 pounds. We entered height - 5’5” and 23 in the BMI box and received her target weight of 138.2 pounds. The Average Daily Calorie Needs for Emily’s target weight of 138.2 pounds is 1576 kcal - Her recommended daily calorie intake to maintain a weight of 138.2 pounds is 1576 kcal per day. The difference between her current calorie intake and the calorie intake for her target weight is: 1695 - 1576 = 119 kcal a day, which is equivalent of 1.2 tbsp of butter, slice of toast with jam or 1 biscuit. Step 3: The Recommended Daily Calorie Intake to Lose Weight. In our example: The recommended daily calorie intake to maintain the weight of 160 pounds is 1695 kcal. Burning an additional 250 kcal per day will increase her weight loss to 1.5 pounds per week and she can get to her target weight in 15 weeks: 21.8/1.5 = 14.5 ~ 15 weeks. more...



How Many Calories Should I Eat Per Day

You learned that in order to lose weight or lose fat, a caloric deficit is the #1 requirement. Now, with your estimated calorie maintenance level in mind, the next obvious step in figuring out how many calories you should eat per day to lose weight is figuring out what size the caloric deficit should be. Of course, one of the main reasons this deficit is so ideal is that it will cause you to lose weight at the ideal rate of weight loss. You see, if you have properly created the ideal caloric deficit and are therefore eating your ideal amount of calories per day, it will cause you to lose weight at the ideal rate. The Ideal Rate Of Weight Loss Based On How Much Fat You Need To Lose. Then, you used that information to adjust your estimated calorie maintenance level and figure out exactly how many calories you should eat per day to lose weight. After that, you learned what the ideal rate of weight loss is for you and this new ideal calorie intake of yours. Are you losing weight at the ideal rate? So, just reduce your current daily calorie intake by about 250 calories (so if you were just eating 2500 calories per day, you’d now eat 2250 calories per day) and then monitor what your weight does over the next couple of weeks. Just add about 250 calories to your current daily calorie intake (so if you were just eating 2500 calories per day, you’d now eat 2750 calories per day) and then monitor what your weight does over the next couple of weeks. more...
