I know at least two people who have had hideous things done to their colon, stomach or other viscera and after an initial weight loss, are just as fat as ever. And then there's Chris Christie. It seems that there are a lot of medical procedures that don't really work but continue to be performed.
Can I make a suggestion? Everyone is always banging on about the fat around your waist and how hazardous it is to your health. It's true that in maturity people tend to get a spare tire around the waist. It happened to me. My weight stayed the same but a small but firm pillow lodged itself just above the belly button and shows every sign of having taken up permanent residence. So why can't the oh-so-brilliant doctors who are removing and remodeling our insides just suction out all the fat? I would be the first person to volunteer for the procedure.
