I really watched carb intake during the weight loss phase, and as sillykitty said, there just wasn't much room for them after getting protein, and then veggies in. My weight came off very quickly - over 100# in 7 months, but I really did journal everything and was very careful. I did my best to maximize the first 6 months that I had heard about, and it worked for me. I added grain based carbs and fats very very slowly as I approached goal weight.
I eat quite a lot of carbs now, as whole grains, seeds, legumes, fruit, and starchy vegetables, I do not eat bread or processed grains except for some chick pea pasta, I am very active and am maintaining my weight loss. If a few pounds creep back on, I cut down on the grains and nut butters. That takes care of it.
