I asked this question about a month ago and didn't receive many replies... I was preband then -- but now that I am banded, I can shed some light.
I chose to do Medifast with my band... at least for the first 2 months. I chose this route becacuse I would get free coaching on the body image issues that I have struggled with and it would eliminate most of the stress about chosing proper foods to maintain nutrition.
I started when I hit the full liquids stage... with shakes, the hot cocoa, and the Soups that had been slightly thinned and then blended. I'm having a hard time getting in a lean and green meal -- so I add a little lowfat cheese or a small piece of chicken to my soups before blending (and blending and blending).
When I move to mushies, I'll add pudding, scrambled eggs, and oatmeal... and then start trying to get in a lean and green every day.
I chose Medifast because I knew that if I was left on my own, I wouldnt be getting full and complete nutrition when I was on the full liquids or mushie stages. I know my body needs complete nutrition to heal.
I don't plan on losing all my weight with Medifast ... I started it for a specific time frame. I figure that there is enough variety that when I can start eating food again, I can still learn bandster rules and not get stuck in "soft food" syndrome.
Example:
First thing in the morning: I hear a lot of people say their band is tight and needs something warm to losen up. I'll have a Medifast hot drink (hot cocoa, chai, cappicuno).
Next Meal: I'll prepare my Breakfast... probably a Medifast Oatmeal and part of my lean and green meal (maybe some egg whites and a little salsa).
Next Meal: I'll have a midmorning snack of a Medifast bar.
Next Meal: I'll do my lunch -- my surgeon says to eat the biggest meal during mid-day -- so I'll do my lean and green here (or at least most of it -- the lean and green portion is huge).
Next Meal: I'll have an afternoon snack -- likely a Medifast shake or a pudding.
Next Meal: I'll do a Medifast Soup or stew and any remaining portion of my lean and green.
So that's what I've worked through in my head so far. Like I said, I'm on full liquids right now, so it makes sense that if I am going to be doing liquids that I should get the best nutrition possible.
Good luck.
