If you have been fasting for a while can I ask how much your lean mass vs fat has decreased.
Since February I have lost 10kg but according to my scales (no idea how accurate this is) my lean mass decreased by 4.7kg (47.3kg to 43kg) and my fat decreased by 5.3kg (13.8kg to 8.5kg).
Is this a high % of lean mass to lose? I have been doing some strength training at home with kettle bells and body weight but have not had much muscle growth so far.
