Finally to conclude let’s just recapitulate that diet is just a way to consume our daily food intake and thus manage our weight, health and majorly our body.

We all should eat the best because it is our prime duty to focus on the health of our body as it is where we reside. A healthy diet does affect not only our healthy well being but also our physical activity, sleep, and lethargic nature is all dependent on the food we consume.

To understand diet the last way to end this article is to quote what Lord Buddha Once said and that; it is our duty to keep our body in good health otherwise we shall not be able to keep our mind strong and clear. This statement in itself is the reason why these diets came into existence and are of utmost importance today.
