I don't remember. What I do remember is forgetting to eat or eating didn't seem as important. I would wait until hunger pains before I ate, then not very well. I lost a significant amount of weight my first month, but your appetite does come back! And I can tell you food taste great for me now! But even now after 6 months on it, I still do not east as often as I use to! I use to weight 190 lbs, I'm down to a steady 155. I'm 5' 10". So it definitely effects your appetite. You definitely get use to it tho! And whatever your lacking now will return. I can still go 12 hours without eating before I get hunger pains. Of course I don't choose to but it's still kind of easy to forget to eat
