Summary. Past research has shown that there are roughly 3,500 calories in 1 lb of body fat.

For example, this would mean losing 500 calories each day to lose 1 lb of body fat in a week.

If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375. If you are moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55.

That lifestyle is burning an average of 1620 calories per day, so if you are consuming more than that then you will not lose weight but rather will likely gain weight. Consuming 1620 calories will maintain that weight.

If it's red, it's an estimate. Here's your equation: MET value multiplied by weight in kilograms tells you calories burned per hour (MET*weight in kg=calories/hour). If you only want to know how many calories you burned in a half hour, divide that number by two.

Just take your current weight and multiply it by 13 (if you don't exercise at all), 15 (if you exercise a few times weekly) or 18 (if you exercise five days or more a week). The number you'll be left with is a rough idea of how many calories you're most likely eating right now.

Here's your equation: MET value multiplied by weight in kilograms tells you calories burned per hour (MET*weight in kg=calories/hour). If you only want to know how many calories you burned in a half hour, divide that number by two.

For males, use the following equation: For example, a 40-year-old, 180 pound, 6-foot-tall man has a BMR of 1,829.8. This means that, at rest, they'll burn approximately 1,829.8 calories in a day (equation: 66 + (6.2 x 180) + (12.7 x 72) – (6.76 x 40) = 1,829.8).

Tipping the scale Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, it's estimated that you need to burn about 3,500 calories to lose 1 pound. So, in general, if you cut about 500 to 1,000 calories a day from your typical diet, you'd lose about 1 to 2 pounds a week.
