yikes, thighs!!!! you have major research to do here!!!!!
there are two basic types of surgery: one is the lap band in which they close off a part of your stomach with a band. this one restricts the amount of food you can eat at any one time.
the second type of surgery alters your digestion and makes your stomach smaller. there are several kinds of surgery in this category, the most common of which is the roux n y gastric bypass. some people have the duodenal switch, and other have the vertical banded gastroplasty.
i've had the roux n y, as have most of the other posters on this board. it's considered the gold standard for losing and maintaining the weight loss.
there are two parts to this surgery: the first is the 'tiny tummy,' it's about 2 oz when they're done. the size of a shot glass or a golf ball. it really holds very very little. the second part is the rerouting of the intestines, which reduces the amount of calories nad nutrients that you can absorb,
between the two parts, we stand a better chance of losing the weight and keeping it off. NO ONE WILL DO THE SURGERY TO HELP A PERSON MAINTAIN A WEIGHT LOSS.
to qualify for the surgery, you must have a BMI of at least 40, which means that you're about 100 pounds overweight, or a BMI of 38-40 with serious other comorbidities: hypertension, diabetes, arthritis, sleep apnea are the biggest ones.
now, figuring 6 calories per gram of protein, 100 grams of protein is about 600 calories.
and yes, you could certainly go on a 500 calorie diet and lose weight, assuming your body doesn't go into starvation mode. and if you lose the weight you want, as soon as you increase your calories you'll gain the weight back. it's a sure way to yo yo and destroy your metabolism.
as for exercising on 500 calories. well., let's be serious here. no one would run a marathon on that, but it's certainly possible to walk, swim, do all kinds of other things. that's the reason for the high protein, in fact. it saves your muscles, keeps your body going, and stabilizes your blood sugar so that you can in fact live.
the surgery alters your metabolism. it gives many of us a set of rules that, if we follow them, we can lose and maintain the loss. that's not the case with most diets.
keep asking questions!!! and check out obesityhelp.com as well...

Keeping it off is a hundred decisions a day that help you maintain what you achieved. And that's the hard part. - L Sanders
