Due to an injury followed by a stomach virus, I drank a lot (coke, iced tea, and water) but hardly ate anything for 5 days. Now, my weight has dropped by 3 lbs.
I feel like I lost muscle mass. However, my doctor told me that while not eating I would have used up fat, not muscle.
If I stop eating for a week, will I loose muscles or just fat?
Clarification: This was not on purpose, I simply couldn't eat.
