So I have lost 210lbs going from 418lbs to 205lbs. I know to add size and muscle I need to eat!!! My mental problem is when I see the scale number go up it scares the hell out of me since I have come so far with my weight loss. I know if the scale goes up its not necessarily fat gain and that it's most likely muscle gainif I do the right thing with my nutrition and workouts. I am currently working out 4/5 days a week. I try to do 20-25 sets per body part. How do I know I am losing fat even though the scale number might be going up. Is there a way to calculate the fat loss and muscle gain. Be so heavy has really mentally messed me up but I really would love to add a good amount of size and even at 51 years of age have somewhat of the body I always dreamed of having. The no shirt at the beach type of body which I never in my life was able to do. Appreciate all and any advice!! Thank you!!
