I am not a medical professional, but I have lost a great deal of weight (was on the low end of obese before, and trend towards very thin now). I've kept it off for at least 5 years, with a small amount of fluctuation (one pant size, isn't so much). I always suggest folks eat most when they find they are the most hungry. It takes a bit of paying attention, but after that it gets easy. I'm personally better off eating very lightly early in the day and eating a large meal at dinnertime. I feel satisfied being full then and don't miss the food early in the day. When I try to eat a full breakfast or lunch regularly, I'm actually more hungry the rest of the day and still want the full dinner. I'm also a night owl, but I do not know if this is related. This holds true no matter what waking schedule I'm on, however. I personally eat a very light breakfast (a piece of bread with some cheese, for example), a light snack if I'm hungry during the day, and a full dinner. Only dinner is a warm meal, mostly vegetarian save for fish once a week. My mother, on the other hand, has done the opposite, She's likely to eat a decent breakfast (instead of a piece of bread with cheese), a lunch, and a light dinner. Her weight loss wasn't as drastic as mine, but she didn't weigh as much either. The thing is that us humans aren't all wired the same way. Even things like insulin response can vary from human to human. I'm guessing there is a genetic component or something to it, but that is an uneducated guess.
