Hello. If you gain muscle, you will increase 200-500 calories per week, and if you lose fat, you will reduce 200-500 calories per week. As long as you can meet the calorie demand as much as possible, but the result will be too much body fat when you gain muscle, or more muscle mass will be lost when you lose fat. At the same time, gain muscle and lose fat can be regarded as a short-term goal and labeled as "impossible". It is recommended to gain muscle in 6-8 months and lose fat in 2-4 months. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
