Protein powder is helpful for fitness and slimming, but eating protein powder without exercise is not very helpful for slimming, because most people say that eating protein powder to help slimming is only to supplement protein powder and reduce our normal diet. This method is extreme and not recommended. Why do athletes drink protein powder is because it is very helpful for us to gain muscle. Nutritional protein powder such as Tomson Bianjian protein powder is also one of the favorite protein powders of many fitness people.
