Forgive me for having misinterpreted you. If that’s your position I don’t see much daylight between your position and the person you were originally responding to though. You have a diet to which you stick not quite religiously. They say you need to stick to a diet religiously to lose weight and keep it off. The difference between your respective positions seems nugatory.
I said the exact opposite actually. I stick to my diet religiously. That's why I believe I'm more disciplined than 95% of people and why I have the freedom to deviate occasionally if I wanted to to eat junk food.
