Is a 500 calorie diet per day safe?

Answer 1

No, it is not. A 500 calorie per day diet is not safe and it can make you gain weight. Any diet with less than 1000 calories will cause your body to go into a storage mode and you could cause injury to your organs.

Answer 2

A 500 calorie diet is far too low. Eating healthier, cutting out fat in your diet and exercise are far more beneficial. Adults need closer to 2500 calories in their diet.
