Low calorie diet

 

Definition of low-calorie diet

Low calorie diets consist of reducing calorie intake:

– Reducing the quantity of food

– And limiting foods high in fat and adding fat.

Low calorie diet is  indicated: if overweight or obese (measured based on the calculation of BMI or body mass index)

Reduced energy restricted diet

Energy requirements are between 2000 to 2200 kilocalories (kcal) per day in men and from 1800 to 2000 kcal per day for women.

– A diet around 1500 kcal per day (reduction of 15-30% of caloric intake) is somewhat restrictive diet. It allows a gradual weight loss.

– A diet between 900 – 1200 to 1400 kcal diet is a “low calorie level” (reduction of at least 50% of energy needs). It allows a loss of weight faster but it is more difficult to follow.

– A diet very low calorie (800 kcal) is very difficult to follow and should not be prosecuted more than a few weeks.

The two main rules to lose weight is to combine calorie reduction with increased energy expenditure.

This is why it is highly recommended regular physical activity (at least 30 minutes per day) that facilitates weight loss and long term weight stabilization.
