    From my personal experience I've only found re-feed worked for me when I was in prolonged (at least 6 weeks) of consistent calorie deficit and I stalled a little. A once a week re feed just tended bump my energy up more the next day as well as a little more water weight.
    I do believe they work, but for each individual I think it's gonna be a trial and error experiment to find out what works.

    For me there are no cheat days, though I occasionally go over calorie limit. I eat what I want when I want, I just stay in my calorie limit.

    The mist important reason I don't believe in cheat days is because I am not on a diet.

    Great thread, I will try a refeed day every few weeks and see how I get on. I like the idea of planning it rather than letting it happen, it means hopefully I will stay in control rather than going over board.

    There is no difference between cheat meal and cheat day.
    Definition of a cheat meal is any meal that pushes you above your desired daily caloric goal.

    If you are in caloric deficit its a meal that brings you to maintenance calories or in caloric surplus.
    If you are bulking and in caloric surplus to start with, its a meal that pushes you in a significant caloric surplus.
    If you are maintaining, its a meal that pushes you in caloric surplus.

    Either way, you are not achieving your caloric goal for the day, meaning its a cheat day. If you eat some pizza or burger or whatever "unheatlhy" (hate that term...) but manage to fit it in your caloric intake for the day, you just made your diet flexible, but didnt cheat because at the end of the day you still managed to hit your caloric goal for the day.

    As for refeed day, its meant to spike your leptin and other hormones level while you are on a significant caloric deficit for longer period. The longer you are in caloric deficit, the less hormones your body produces. Leptin is responsible for the speed of your metabolism so when your leptin levels drop, your metabolism decreases which slows down your fat loss progress. Leptin is carb sensitive so essentially what you want to do on refeed day is to keep your protein and fat intake stable, since those do not effect leptin, but increase your carb intake. The amount of carbs you can increase for refeed day varies from person to person, but a good place to start is to increase your carbs to the level of your maintenance calories. One refeed day, or two refeed days a week..thats up to you and depends on how severe caloric deficit you are in. Try and see :)

    I have learned over time not to try to think about it so scientifically.....instead I go by what my body tells me......when I need a refeed/cheat....whatever the heck you want to call it....there is no question about it, my body will tell me......I will feel lethargic, moody and just overall physically and mentally drained. I find it impossible to plan a specific day when this will happen so I don't necessarily plan it out but when I do refeed, I will make sure to carb load and give my body the things it has not had a lot of...rice, pasta, maybe dessert or alcoholic beverage if I am using it as full blown cheat meal, etc....next day I always feel great.....happens about once a week on average. It is definitely just as important mentally as it is physically.
