How many calories does it take to lose a pound, that is, how many calories to burn to lose a pound? Almost all of us are used to answering: 7200 calories, which has made popular diets in which every day about 500 calories are cut every day with the hope, reaching a weekly calorie deficit of 3500 calories (or 3000 if for example Sunday is free), to see the scale go down by half a kilo a week. 
Has this ever happened to you? First question to ask. Did you go on a low calorie diet where you reduced your daily calorie requirement by exactly 500 calories, did you lose exactly half a kilo a week for all weeks of the diet?

Most of the time not . Or: did you go on a diet where you said goodbye to pasta and pizza, didn’t count calories (but there was certainly no precise deficit of 500 calories a day) and lost more than a pound at the weekend? Yay: you said to yourself, what magic is this?
Then calories don’t exist! I live on 1200 calories a day and at the weekends the scale moves by two ounces, I live by eating turkey and surimi all day to fullness and I lose a kilo and a half in three days. Maybe surimi lo puccio even in mayonnaise.
Cool. What is magical about my body?
What is it that the lobby of dieticians who are certainly plotting against us does not explain to us?
Now I try to explain it to you. Let’s go back to question one.

How many calories does it take to lose a pound? If we rely on a simple mathematical calculation, from 7000 to 9000 calories, it depends on how we consider this kilo: if of muscle and fat, if all of fat, and so on. From this calculation, as I said in the introduction, the custom of reducing our diet by 500 calories per day arises. Why don’t you lose exactly one pound after one week and one pound after two?
