If you are doing resistance training and want to increase muscle strength, it is good to eat some protein powder at night.

You can also eat protein powder during fat reduction, depending on your physical needs.

Now, you have to understand that you have to reduce hunger, which may also include proper energy supplement, but this has nothing to do with protein powder.

You should choose a food type that is high in fiber, low in carbon and low in fat, and at the same time can "satisfy your desire".

For example, whole wheat products, vegetable products and qualified meal substitutes.

If your diet is the main way to lose fat, you'd better not eat protein powder. Boiled eggs and chicken breast are more suitable. Simply put, I'm hungrier.
