My body did chomp its muscles in 2012 and it was horrific, but it took a near fatal illness to make that happen.
Agree, no where as bad as your experience, but after falling off the bike a few years ago and breaking a rib I couldn't eat for about a week. My weight absolute plummeted, I was also doing strength work, took me about 4 month to get back to lifting the same weight dumbbells.
