Your fiber really should be coming from the low glycemic veggies you are eating. It IS important to spread your carbs out over the day - if you load up at one point in the day... you just spike your insulin level and that is NOT what you are trying to achieve. Try having scrambled eggs with some peppers diced up in them for breakfast, make lunch a big salad with lettuce, cukes, etc and some meat and a full fat dressing. Then for dinner have a serving of meat (6 to 8 ounces) and 1 cup of allowed veggies OR 1 cup of salad with dressing. As for snacks... if you are hungry between meals then use have some protein for a snack... but keep the portion size small and try not to just eat because you want the sensation of being "stuffed" and the sensation of tasting something good. Eat until you are satisfied - not stuffed.

Hope that helps.
