You need to lose fat, so you don't need muscle powder. Lose 30 pounds in 3 months, and your figure may get smaller. You should be mentally prepared. I suggest you lose weight (fat) first, and then gain muscle. Otherwise, you will lose weight in three months, and it will be difficult for you to eat except for the amount of training. Extremely difficult. You can lose weight in 50 days. About 135 kg, and then make a muscle training plan. Weight loss plan: a lot of aerobic+a little strength training combined with weight loss diet. Remember, as long as your absolute strength is there, your muscle mass will decrease the least. Muscle building plan: moderate muscle training+a small amount of oxygen combined with muscle building diet. Muscle training time should not be too long, preferably within 50 minutes. Pay attention to the timely supplement of various diets. And the diet should be very strict.
