No Snacks, no sweets, no seconds. Except on Days that start with S. Too simple for you? Simple is why it works. Look here for questions, introductions, support, success stories.
I just started No S and I think it's fantastic! One question for Reinhard...if someone were to just not like sugar anyway, and really just enjoys the structure of the 3 - one physical plate meals and feels satiated from them and has no desire to take S days, would you still acheive the same results...or are S days set so that physiologically they increase leptin etc..so that you can burn more fat on N days. Thanks Reinhard!
There is no science here. S-days are a release from the restrictions of the week rather than a direct aid to weight loss; I rarely bother with anything sweet, though I do occasionally snack on S-days.
I don't know a thing about leptin. The power of S-days, as far as I'm concerned, is psychological and motivational. If you don't need them, skip them. But I think the vast majority of people will find them valuable -- so be careful not to jump to conclusions.
