Dear Wiley,
For once, I agree with someone who is at a plateau and thinks they dont need a fill! Well, that being said here's my advice for what its worth. I totally know what you mean about the snack foods, they go down pretty easy and they are not good.
I have mentally told my self that I can have anything because any restrictions or dieting is just no good for me and it leads me to the snacks. So I instead have foods I MUST eat and those are the proteins. For me that is mainly beans, tofu, and fish but you get the idea. I MUST eat those at the beginning of every meal (or whenever I want to eat regardless of mealtime or even hunger) and then usually after that I cant eat very many snacks or whatever else.
I just mentally cant have no-no foods - it just makes me want them more! So now I have MUST-HAVE foods and they keep me out of trouble for the most part.
Also (for what its worth) I have a glass of wine after dinner and it really curbs the snacking...I think I would be a skinny alcoholic! But for a lot of people, any alcohol lowers their ability to say no, to snacks or whatever else! Good luck...you posted a very interesting situation and I will be interested to see what others say...
PS: There are two ways to turn on your metabolism in the morning: eat (not an option for me either) or exercise. Even a 20 minute walk will do it.
