One of the best tips for natural diet plan is that one should eat to one’s capacity. A simple rule suggested to judge your capacity is to divide your stomach hypothetically into four parts. Of these, two parts are to be filled with solid food, one part with liquid. The fourth part is to be kept empty for the proper functioning of gases. Also, immediate exercise in any form after the intake of food is to be avoided. The night meals should be taken 2 to 3 hours before sleep.
