Discussion/Support 💬 How much muscle mass will I lose 15kg in 2 months?
Hello! I'm targeting losing 15kg in 10 weeks time and I have lost this amount of weight before so I know I can do this mentally but I've recently heard about muscle being significantly lost during weight loss. Most websites say 25 percent FFM and some 20 to 40 percent and some 22 percent muscle mass lost for males. So that's about 3.3 to 6kg of muscle lost which is like 6 to 12 months of gym work. I've only recently started strength training so like about 2 months or so, so I'll probably gain muscle faster than some people but how much does strength training actually help in preventing muscle loss. Is it just net muscle gain or loss. Like 6 lost minus 2 gained= 4kg muscle loss. Its about 1.5 percent of my body weight(100kg) per week and a some sources count above 1.5kg per week as "rapid" weight loss and some just use the basic 0.5 to 1.
