Calorie restriction (CR) implies the reduction of calories in order to improve health and slow the ageing process. Animal testing has proven CR to be an effective anti-ageing dietary solution.

This involves limiting the intake of macronutrients such as protein and carbohydrates while maintaining the amount of micronutrients.
