Hypocaloric Diet
A low-calorie diet is a diet in which you consume fewer calories than your body uses.
That is, if your body burns 2500Kcal and you only eat 2000Kcal, you are following a low-calorie diet.
What a low-calorie diet is for you may not be for your colleague next door.
It is important to know the calories you use daily, as person A can spend 2000Kcal per day and person B 3000Kcal per day, a 2500Kcal diet will be hypercaloric for person A and hypocaloric for person B.
Low-calorie diets are used to lose fat/weight.
Hypercaloric Diet
A high-calorie diet is the opposite of a low-calorie diet, that is, you will consume more calories than your body uses.
If your body burns 2500Kcal daily and you consume 3000Kcal, you will be following a hypercaloric approach.
The same example of a low-calorie diet can be applied here, individual A spends 2000Kcal per day and individual B spends 3000Kcal per day, in a 2500Kcal diet, individual A will be following a hypercaloric diet and individual B will be following a hypocaloric diet.
Hypercaloric diets are used to gain muscle mass/weight.
To calculate an average of the calories your body uses daily, use this formula.
