How Many Calories Should You Eat Every Day?

Don't guess at the number of calories you need to to lose (or to gain) weight. Click on one of these calculators:

Men's Calculator | Women's Calculator

This is just the first step for changing your weight. You also need to keep track of all the foods you eat and your physical exercise. You can print out and make your own food diary, or join a website like Calorie Count.

My calculators are based on the Harris-Benedict formula for determining your basal metabolic rate (BMR), plus your active metabolic rate (AMR), which is based on your estimation of your daily physical activity. Each calculator will also give you suggested amount of carbohydrates, fats and protein, based on your daily calorie need.
