Yep!
I've done it, was on Optifast in 1990. Did the whole 12 week 800-cal/day fast for an 18-month study on weight loss maintenance.
I was one of the **very few** people who managed to keep the weight off in the study though, so don't run out and sign up for Optifast on my 'recommendation'. I believe there was a 3-5% success rate out of quite a large group of women (Stanford University did the study). According to the end of study results, the average person in the study started out at around 102 kg (about 225 lb) at the beginning of the fast; at 3 months, (end of fast) they were at 82 kg (about 181 lb) for an average weight loss of 44 lb during the fast...unfortunately, most people in the study started to gain weight almost immediately after the fast was over and real food re-introduced...18 months after beginning the fast (the end of the study) the average was back up to 95 kg (209 lb).
Here are my stats if you're interested: beginning of fast 119 kg (262.34 lb - I started walking regularly before the fast), 3 months 83 kg (1 kg above the average); 6 months 81 kg (178.57 lb) 18 months - end of study - 83 kg (182.98 lb). And of course here I am now, I have no idea how much I weigh since I haven't weighed myself since July, but I bought my first pair of size six DKNY jeans (actually two pairs - the classic fit and the low-cut!) last month...considering I was a size 26 in 1990 I'd say I'm doing pretty well...
So what was the diff for me? I think I was more determined, perhaps, than most of the rest of the group to really and truly make a permanent lifestyle change. As I stated before, I started a walking program before even starting the fast, I also had a great workout video (called "Idrea says 'Yes You Can!'" LOVED it!) that I did faithfully three days a week until I was brave enough to go to a low-impact aerobics class at the local Rec center...One more thing, I joined a large women's exercise group at Kaiser for a couple of months (these aren't geared towards weight loss - we did dance steps, yoga, a little bit of everything - basically it was just to get comfortable with our bodies amongst others...) and that helped IMMEASURABLY. After the fast (feeling more comfy and with elevated self-esteem at 182) I started going to Jazzercise and just really enjoyed the cameraderie with the workouts of course!
Basically what I'm saying here is what our group counselor told us at the beginning of the study - to just think of this as a 'jump start'. Trust me I know - when you weigh 265, thinking about making 'sacrifices' for a relatively measly 1-2 pounds a week just seems like forever...
But ya know, losing bodyfat and getting healthy, lean and fit IS a forever thing - but it doesn't have to be like a jail sentence!
Good luck!
