When you consider
that people are suffering and dying in droves because it so hard to
modify diets and society to eat better and get exercise, then drastic
actions such as bariatric surgery should not be viewed as lack of
will or vanity or other negative biases.
This technology is both swallowable and removes it self by going down the digestive tract. The others are removed endosocopically, or and placed endscopically. Nausea may be a problem with these things, but they do seem to have effectivelness over 3 months or so with dieting. Probably not as effective as bariatric surgeries, but ideally less risky and costly.
