First off, I have to speak in Hollyhouse's defense - she has made supportive posts.
That done... Hollyhouse does have a pattern of going off the plan and then venting on here about it. She got upset at recent responses and seems to have left in search of more of a blog atmosphere where she can just confess to silent cyberspace... which I personally would not get much from, but whatever works for you Hollyhouse!
Anyway... Medifast is a great way to lose weight, for any lurkers out there, or people on the fence. I wanted to toss my hat in the ring and say this too. It is VERY healthy! Easy? No. Unusual? Yes. But dang, it WORKS.
Yes, you WILL feel weak, hungry, miserable, etc., if you do not stay true to the program for the first 3 days. Once in ketosis, it becomes remarkably easy to do (imho.)
You will still have "head hunger" or the mental munchies, but you won't really be physically hungry until a little bit (half hour or so) before your next MF meal. Least, that's what I've found!
If you love to exercise hard-core, for more than 45 minutes a day, or at an intense level, and you cannot stand to not do this, MF will probably not work for you. It's just not designed to support workouts that burn several hundred calories. I mean, how could it, being about 800 calories a day?
There are lots of ways to lose weight - Hollyhouse might do best with more calories, more exercise, and more carbs. You might too, reader, but if you like what you see here, do not be deterred by one customer's bad experience with Medifast - which was (unfortunately) pretty much brought on by her own actions.
Holly - best of luck to you, and I hope you find the support you need out there!
