First, eating protein powder, with a certain intensity of training, will reduce fat, but the premise is high-intensity training. Second, protein powder should be appropriate. After a training, it is generally about 25 grams of protein powder. Excessive protein powder will increase the burden on the kidneys, and the extra amount cannot be absorbed. It is normal that you are a little fat and your breasts are a little stiff. Please consult a fitness instructor to reduce chest fat. After the chest muscles are trained, the whole chest muscles stand up smoothly instead of nipples, and you will feel that there are two bricks on the ribs, which is particularly stylish when you wear clothes. The last word of advice: persevere and step by step.
