Step 5 of practicing calorie restriction (CR)

The step 5 of practicing calorie restriction (CR) is to have food diary on all the foods you take for the day. Your diary should include the energy (as shown on the food label or estimated quantity)of each item of the food you take

The total energy of the foods should be less than that your body needs.

However, the energy intake daily should not be less than 1200 kcalories.

At the end of each day, you should calculate the difference of kcalories needed by your body and the energy you have taken in to find out whether you have successfully restricted your calories intake for the day.
