The idea is that every meal is to satiety, but no between meal snacks, and on odd days you might have 3 meals, and even days just 2 - that would be a 3:2 pattern. But it could be a 2:1 pattern, or a 3:1 pattern or a 3:0 pattern, or even in maintenance a 3:3 pattern. The point is to eat meals low in carbs that minimize the amount of insulin your pancreas has to make, and then have a good period between meals where your insulin goes as low as it can between meals, and your fat oxidation is uninhibited (to the degree you can lower insulin).
We’ve had @karen on the pod before, but if she’s up for it @carl and I may have her back some day to explain how this works.
