I know of a couple of good friends who did the gastric bypass surgery and yeah, they had to eat a lot less after the surgery, but prior to having the surgery done, they could not do it on their own. When you are 250+ overweight, eating a 1/2 tuna sandwich like you can after a gastric bypass is not a realistic way to lose weight. At 400+ lbs, your stomach is so enlarged and if you ate skimpy meals, you would literally feel like you are starving yourself. Both friends that had the surgery, said they could eat a small bowl of soup or 1/2 sandwich and for the first time in their lives, actually feel satisfied from such a small portion. The surgery is what worked for them to get them on the right road to health.
