Also no 2 humans are the same, as our conversation indicates :)
Still, I have a hard time believing that ketogenic dieting didn't "work" for you, but not knowing what your daily menu was (it's easy to throw it off by accidentally eating too much carbohydrate), how long you tried it for, etc.
It didn't work for me because it made me queasy. I need my carbs. I couldn't stick to it. No doubt if I could have, I would have lost weight with it.
To simplify the low glycemic diet, eat all you want from the desireable list, choose sparingly from the moderate list, and avoid the undesireable list (which I posted above). I love the simplicity of that and also the balance of it. No food group (grains, meats, fats, fruits, veggies, dairy) is to be avoided, just chosen from wisely.
That works for me because the choices include a healthy dose of carbs, which makes me feel comfortable.
I have nothing against low carb and I would never discourage anyone from following it if it's what works for them. It's just not for me.
