This cannot be correct, right? Muscle mass is at 115 lbs, but fat-free body weight is at 121 lbs? If I look at myself in the mirror, hardly any fat at all. My body looks somewhat lean, to me it looks very healthy. Maybe it is correct because my height is 5’6″ so I think 158 is overweight already. My goal is just 143 lbs. Maybe 140. I am doing well. I am not even doing any exercises, just eating less or having a diet. 133 is doable but I think that is too much weight loss. 140ish is good enough.
