What helps me to stay committed is to focus on the benefits I'm getting from this WOE, especially those other than weight loss. Maybe it's easy for me because I have diabetes in my family so all I have to do is look at my father. Also I have PCOS which is virtually gone now, so if I feel tempted by sugar all I have to do is remember that hell and walla! instant willpower! But there are so many other fringe benefits, such as no more heartburn, no more depression, better skin, nails, etc. Maybe you could come up with your own list and refer to it when you feel tempted to cheat. You can then feel proud of yourself when you choose your health over a certain food, and making that choice is great for self-esteem.
