I'm in my skinny jeans! I've been eating big breakfasts (today's took me 10 minutes to make), a moderate lunch, and salads or veggies for dinner, sometimes meat, for 10 days. I tried these jeans on last Friday...had to "suck it in" to zip them. Today, they zip right up.
To check my breakfast regime, see:

I am not hungry, I don't have afternoon or evening cravings, and I don't feel deprived. I do think, however, that eating "grains" instead of bread with breakfast makes a difference in combination with the greens. The DH eats toast with his breakfast. He ate grains yesterday and was so full at lunch, he didn't finish his salad. He is an afternoon (no--all day grazer). He said that he was surprised at how full he was all day.
I committed (to myself) to try it for 30 days, give or take. I'd say try it for a week, even 3-4 days.
