I have, at different intervals in my lifetime so far, attempted and succeeded to lose weight. My weakness and where I research for help is keeping weight off and breaking the one plateau I've had, not losing weight. I love data, lists and tracking. My most successful diets were also the diets where I meticulously and obsessively tracked multiple variables. Tracking keeps my head in the game and just as importantly, gives me data to help my attempts to lose weight be more successful. Some people loath the busy-work of tracking and won't ever crack open a notebook or a weight loss app.
