Hi Hannah,
Sorry to hear of your disappointment with your loss so far. I'm no expert on this, but have a few questions/comments for you about things that may be affecting your weight loss:
1) How many supplements (and which ones--shakes, bars, etc.) are you having each day in addition to your meal?
2) Have your bowel movements been regular? I know, not the kind of thing you want to talk about, but being irregular can really affect your weight, showing an additional 1-5lbs when backed up.
3) In the Medifast starter guide it says that some women may experience cycle irregularities because when fat is loss so quickly, excess estrogen is released along with the fat. The fact that your cycle has been irregular may be attributed to this. And if this is so, that means that you have definitely loss a lot of fat; perhaps more than what the scale is showing.
4) The fact that your cycle has been infrequent may be contributing to extra water retention. You might have ovulated, twice in the same month, and this can cause two-three weeks of water retention (this happened to me before Medifast). We always retain water (I retain between 4-7lbs myself) before Aunt Flo shows up and after she arrives. So, I'm looking at a 10-day or so period a month where the scale does not move (it did it this past month for me, too). You could be retaining 5-10lbs of water until your hormone levels normalize and extra water is shed.
5) You said that you are drinking a minimum of 64oz of water--how much above that do you go sometimes? Many of us, myself included, drink between 96-128oz of water a day (some even drink 140oz a day! But I think your activity level kind of dictates this). Yes, this is a lot of water, but it really helps with the weight loss.
Gerald gave some pretty good advice, too. If you could list what you eat during an average day (including any chewing gum, artificial sweetners added to coffee, bouillon cubes, etc.) this would be helpful. Also, the metallic taste in your mouth is indicative of you being in ketosis, the fat-burning state, so it sounds like you are doing things well.
I'm sure Nancy and others who have been on this plan longer than I have can offer some comments and advice.
Hang in there
! Let us know what your daily menu and activity level (do you have a desk job, do a lot of walking everyday, other exercise, etc.?) is--someone can most likely give you an idea of any adjustments that you may need to make.
