Various methods have been proposed in psychology and nutritional sciences to reduce obesity, which include various methods of reducing the volume of food and meals, drug therapy, surgery and exercise. Research evidence has also shown that obesity reduction programs in practice have not been associated with satisfactory and expected success. In this article, with the method of analytical research of verses of the Holy Quran and narrations and the library method, a suggested treatment plan for dieting has been presented. The proposed method is fundamentally different from the common methods of reducing obesity in terms of principles, goals, motivation, measurement and method. The Holy Quran; It does not mention diet and weight loss and pursues a bigger goal, which is not to waste. If we learn not to waste, obesity will also be reduced. Therefore, the tool for measuring overweight is to measure and calculate not to waste, not to continuously calculate weight. Also, in this method, there is no diet plan to reduce obesity. In general, the proposed treatment plan for reducing obesity based on the Holy Quran and hadiths is presented in four stages. The first stage: teaching the concept of not wasting food and drink, the second stage: observing eating etiquette, the third stage: self-control and meditation, and the fourth stage: continuous follow-up and evaluation. The results of this research need more analytical examination of Islamic texts and empirical confirmations.
