Diabetic people actually need carbs as if they use insulin shots, they often get hypoglycemic. If you have an active lifestyle, your BG actually just replenishes your glycogen depots and possibly you don't have much excess fat anyway. So, live a healthy lifestyle and then a moderate diet will work just perfectly!
Anyway, fat deposits in moderate size are not a bad thing. In fact, in many cases, they save lives - the evolution did not invent them without a solid reason. Yes, excessive fat is bad for men as it's feminizing, but doesn't have a huge impact on women when you look at the studies. There's also a good reason why fat is not so easily mobilized.
Yes, a low carb diet makes people feel less hungry, so they eat less. A (supposedly) "normal" carb diet makes many people hungrier than they should be so they eat excessively.
I doubt you really feel that comfortable because then why wouldnt you eat like this all the time? Just that you are referring to it as a "fast" tells me you are craving food. If you ate less because you felt satiated, you wouldnt refer to it as a fast.
I don't even know what you are talking about regarding overeating fat. My experience is just cut out the grains and sugars and eat whatever else you want. If you crave fat, then you eat it. There is no overeating involved. That is the entire point, if you keep your carbs low enough you do not want to overeat anything. There is no self-control involved, in fact you need to sometimes force yourself to feel like eating for social/etc reasons.
There is also no need to purchase "fancy fats", you do probably have to prepare your own food though since sugar is added to everything prepared for you.
>"All these diets ignore the most recent scientific discovery - epigenetics!"
This is hardly recent, and while I'm sure it has some sort of relationship to a persons optimal diet, no one has any idea what that is.
All I did is stop eating bread and preparing my own food so there was no sugar in it. So this extreme diet you are talking about seems like a strawman to me.
>"people should eat quality foods aligned with their genetic and epigenetic profile"
No one knows what this would be.
> "Don't eat too much carbs, don't eat too much fats, don't eat too much meat"
Which your body lets you know via a satiated feeling without gaining undesirable weight. "Too much carbs" seems to be over 50-100 g/day for most people. If it wasn't, they wouldn't eat more than was healthy.
