Does sleep affect weight loss? My sister and I were talking about it because Ive seem to hit a plateau almost from April... not only was there junk food but now my sleep is all messed up. I wake around 6:30am, have maybe an hour nap at 1:00pm then I work until 12am, get home and go to sleep around 1am, and now that I am not really eating junk anymore and I am exercising a lot more, my weight is kinda stuck! Mostly since April Ive been the same... in between 195lbs up to 205lbs. Any thoughts?
