Hi, I hope you feel better.

I have a cold and no appetite so I understand.
I was on medifast for a month and my calories were 800-1000. So my body got used to that calorie intake and I would gain if I ate more than that. If I had been on a 1,600 calorie diet, my body would have been used to that. Does that make sense? You don't want your body to think it only needs a low calorie amount.
I went off of medifast last week just as I got a cold and began to eat normally. I have zig zagged calories between 1,200 and 1,900 for a week and did not gain like i feared. I lost 1.5 I also eat every 3 hours or so and include protein.
It's really had to work at getting all of my calories in and I still can't taste anything. Hope this cold is over soon!
