In defense of the Indian method eating 2 meals is not about eating less but is about not spiking insulin quite so much. It implies a fasting window. As to the notiion that eating low protein and higher carbs and fruits is helpful in prevention of diabetes in Asia, this makes sense in the context of their genetic ability to digest high quantities of starch combined with active lives which has historically resulted in low rates of diabetes and other 'diseases of civillisation'. There are certainly lots of populations remaining healthy on this kind of diet as well as those who heat High Fat Low Carb, including many in the blue zones (centegenarians) of the world. The common factors are active lives, low sugar and processed foods. When you take rural people into the cities and they change their diet to one which is more Western it is then when disease rates creep up or in the case of China explode e.g. 2% type 2 diabetes to 11% type 2 diabetes in one generation.
As for TOFIs we all have an personal fat thrreshold (according to Prof Roy Taylor's research) i.e. a level of fat around the liver and pancreas that we can tolerate. It is known to be lover in Asians and there seems to be a lot of variance in caucasians too hence someone of normal bmi diabetic if they have gathered fat in the wrong place. If you ate your traditional diet but ate a few more sweets and became more sedentary, you'd lose muscle mass and become less insulin senstive thus encouraging all the steps that lead to diabetes without necessarily gaining much m weight overall. This is what we attribute to ageing in the West.
