When the calories intake exceed the energy expenditure, a person's weight will increase. Based on the user's profile, Mealformation, estimates the number of calories required to sustain the user's current body weight, by calculating the estimated energy expenditure. To lose weight, your c alorie intake would have to be reduced to a level below your energy expenditure. Since there are approximately 3500 calories in one pound of fat, you would need to lower your daily calorie intake by about 500 calories per day to lose one pound a week. As an alternative, you could raise your physical activity level to burn additional calories.
Physical activity is an important way to use up food energy.
The calorie estimate from your personal profile is based on your current weight, so if you are overweight the calorie estimate will be somewhat high or if you are underweight the calorie estimate will be somewhat low. People with large bodies require proportionately more energy for activities than people with small bodies. While the calorie estimate may represent your daily energy expenditure, you should be aware of the recommended calories per day for people of average weight. The values shown in this table represent average calories by age and weight. They do not take into consideration the individual's actual weight or activity level.
