A new study shows that starvation (eating 600 kcal/day) can reverse type 2-diabetes, just like gastric bypass surgery.
Again, there is no need to explain the effect of the surgery with other speculative theories. The resulting starvation reverses diabetes. And the starvation isn’t even necessary to do that.
If a type 2 diabetic stops eating (carbs) the symptoms of diabetes starts to go away. But starvation or surgery are unnecessarily painful ways to do it.
Luckily diabetics can eat real food to satiety, as long as they avoid sugar and starch. The food that quickly turns into simple sugars in the gut. Cutting away their stomach or starving themselves is not necessary.
All they need is good food.
A Gastric Bypass operation protects from eating too much carbohydrates in two ways. Number one: you can only eat miniature portions of anything. Number two: the smaller amounts of starch you eat is not digested as easily as the duodenum with the starch-digesting enzyme amylase is diverted from direct contact with the food.
