No real weight loss after the initial 5lbs. Meaning that after 5 days they'd lost all the water and stored glycogen and didn't understand the difference between weight loss and fat loss. Then they got disheartened when they didn't lose a pound a day after that. Some girl in my office was talking about how she lost 4.5kg in her first week of crossfit. I pointed out to her that unless she ate nothing there's no way she lost 4.5kg of fat and that the weight she lost was water weight, glycogen and a little bit of fat. I  23c  t's funny watching someone be so angry, so absolutely convinced that you're wrong or lying but have no idea why. Funny, and also depressing.
