On another forum that I'm on many of us do the Leptin Reset for phase 3, and we stabilize like a rock or keep on losing very very slowly. It was designed by Dr. Jack Kurse (google him for his website) and you can read it online. Although, be warned, he's a doctor and there's a lot of science talk!
Basically the Leptin Reset goes something like this: for 6 to 8 weeks:
BAB = Big Ass Breakfast within 30 minutes of rising. Eat 50 to 75 protein grams for breakfast. That is a huge protein filled breakfast! Not easy to do!
Eat 30 to 50 grams of healthy carbs (no sugars, no grains, no lactose)
NO snacking at all between meals.
Eat 2 to 3 meals per day, spaced 4 to 5 hours apart. Last meal is finished minimum 3 hours before bed.
Sleep 8 to 10 hours per night.
What most of us are experiencing is that the BAB shuts off our hunger for the rest of the day. We eat a normal size dinner, some eat a light lunch, and we're just not hungry for more than that. It's amazing, because prior to doing this I fought the urge to snack at night. I don't even think about it when I start the day with BAB. About half of us trying it are losing 1 to 2 lbs per week without trying, the other half are stabilizing at LIW.
