But...this is a great example of something working for someone, and then they go on a crusade of why "it's the best" with lots of random untrue statements.
> It seems the MAIN problem is NOT total calories
No that is the main problem, and you got healthy by restricting them, which resulted in loss of weight, which resulted in an improved sensitivity to insulin.
> MAIN problem is simple carbs / Sugar.
Simple carbs and sugars are not more fattening on their own.
> Exercise will just make you hungry.
Exercise is the single best thing you can do to improve your metabolic health, even above dieting, which is great that you do that too.
> It is VERY VERY hard to stay away from simple / carbs / sugar but you can do it
I think when you say "simple carbs and sugars" you're referring to the droves of hyper-palatable, calorically dense packaged foods that are out there. These are not necessarily "dangerous" on their own, but they are easy to over-consume which leads to a caloric surplus, which leads to weight gain, and thennnnnn all the bad stuff follows.
I like fig newtons and eat them everyday :)
