There are many myths about diets. So here are the observable facts. Long term they very rarely work. Low carbohydrate diets work quite well short term, but are impossible to stick to and can cause health problems. Great motivation is required.

The more you eat the more your stomach swells and the more you feel hungry, isn’t exactly true, but it does give you the idea. Operations to reduce the size of your stomach can actually work long term. There are health risks but if your situation is so bad that the heath risk from your weight or hiatus hernia (for example) is greater, The operation can be recommended. After the operation, it’s the pain and discomfort that you get if you eat more than a tiny amount of food that gives the motivation required, as mentioned earlier. Vitamin supplements are required.

It would be better if the governement took action to avoid this situation.
