This Australian article quotes a British expert who believes:
DIETS can never help the overweight become slim; the only option is surgery, an expert on weight loss claims.
As people put on kilograms, the body “accepts” the new weight and tries to restore any losses as quickly as possible.
Nick Finer, professor of obesity medicine at University College London: “What these figures show is that dieting is, for most people, completely pointless.” he said. He will suggest that the best way to tackle the obesity epidemic would be to set up networks of fat clinics to carry out mass programs of gastric bypass surgery.
He then adds:
Gastric bypass surgery involves bypassing a section of the small intestine so there is less room for food to be absorbed into the blood.
Professor Finer said: “Initially this operation was thought to work simply by preventing so much food being absorbed but what is emerging is that the operation also alters the nerve and hormone signals from the gut to the brain. It means people feel fuller, faster and for longer and so they stop feeling hungry.
My experience has been that changing WHAT I eat has also done the same thing – it changed the “nerve and hormone signals from the gut to the brain.” I also feel satisfied after my meals. I do not go hungry! I eat lots of green veggies, complex carbs, and simply prepared fish (only occasionally meat).
