![]() ![]() The formulas for calculating this number are as follows, using kilograms for weight, centimeters for height, and years for age ( 9). ![]() To calculate your RMR, use your sex, age, height, and weight to adjust the formula. Your RMR is the number of calories your body needs to function, and it does not include your daily physical activity and other movements. In some cases, your healthcare professional may want you to gain weight quicker, so be sure to listen to their advice. For example, you may wish to reduce the time, frequency, or intensity of your exercise. You may also want to cut back on your physical activity if you’re extremely active. If you struggle to eat large meals, you may want to eat smaller meals more frequently. Ideally, choose nutrient-dense foods that are higher in calories to support gradual weight gain. While it may seem obvious to eat a very large amount of calories and limit your physical activity, this strategy isn’t ideal, as it will likely lead to excessive fat accumulation and removes the important health benefits of exercise ( 8). If your calorie needs are 2,200 calories per day, a calorie surplus of 10–20% would be 2,420–2,640 calories per day. A mild calorie surplus of around 10–20% will allow for slow, gradual weight gain. This means that you’re either eating more calories than your body needs, expending fewer calories, or a combination of both.Īs in the case of a calorie deficit, you’ll want to do this slowly to ensure it’s healthy and sustainable. If you want to gain weight, you need to be in a calorie surplus. If you’re losing weight, you’re liking not eating enough calories or expending too many calories. If you notice that you’re gaining weight, this is likely a sign that you’re either consuming more calories or expending fewer calories than you intend to. To figure this out, you’ll need to calculate your TDEE, which is the number of calories your body needs to sustain the weight you’re currently at. If you’re looking to maintain your weight, you’ll want to ensure your calorie intake matches your calorie expenditure. ![]() Therefore, you may need to work with a healthcare professional who can develop personalized recommendations for you ( 7). That said, weight loss can be influenced by a variety of factors, such as age, genetics, hormones, medical conditions, and medications. A mild calorie deficit paired with resistance training can help preserve lean muscle mass while also promoting fat loss ( 4, 5, 6). Your body may employ mechanisms to prevent further weight loss, such as sluggishness or a reduced metabolic rate ( 2, 3).įurthermore, too large of a deficit can lead to loss of lean muscle. While you can achieve weight loss quicker with a larger calorie deficit, it may be difficult to sustain long term since it will likely lead to significant hunger. Let’s say that your body needs 2,200 calories per day. This means you’re either eating fewer calories than your body needs, burning additional calories, or a combination of both.įor sustainable weight loss, an ideal calorie deficit will be around 10–20% fewer calories than your total daily energy expenditure (TDEE). To lose weight, you must be in a calorie deficit. The number of calories you should burn in a day largely depends on your personal health and fitness goals, as well as other factors like your age, sex, height, weight, and activity levels. How many calories should I burn in a day? This article teaches you how to calculate your calorie needs based on your health goals. Eating fewer calories than this will likely result in weight loss, while eating more calories than this will likely lead to weight gain. With one more calculation, which considers your activity levels, you can work out how many calories you need each day to maintain your current weight. This formula calculates your resting metabolic rate (RMR), also known as your resting energy expenditure, which is the number of calories your body needs to function at rest. If you’ve ever wondered how many calories you burn each day, the Mifflin-St Jeor formula can help you figure this out. You also burn additional calories from everyday movements, as well as exercise, which can vary considerably from person to person. However, the amount of calories you need each day is unique to your body and activity levels ( 1).Ĭalories are important for basic bodily functions, such as: Most female adults need 1,600–2,200 calories per day, while adult males need 2,200–3,000 calories per day. Every day, you burn calories when you move around, exercise, and go about your daily tasks. ![]()
