The quickest way to lose weight is not to eat. If you want to eat, you should also eat something high in protein and low in fat, such as beef. Before, a friend of mine bought a bucket of protein powder to lose weight, that is, he ate a spoonful every day and put it in milk, and hardly ate anything else. Sometimes he eats boiled eggs and beef, but the quantity is very small. This kind of weight loss effect is very good, it can keep healthy, energetic and successful. Vitamin supplements are also needed when necessary.
