Being mostly in the maitenance/maybe a couple more pounds phase, I do find myself slipping back into old habits from time to time. I am especially susceptable to artisan breads and ODing on cheese and crackers. When that happens I have found that a day or 2 of fasting helps me regain my perspective on eating to live, rather than living to eat. It may not be for everyone - but it works for me
