High Calorie Days?

Either that or that is just their cheat day. But yea, it helps to keep metabolism high. Eating those extra cals from carbs does it the best. What I do when I lose fat I don't even go to calorie deficit anymore. I just add a high calorie day a week where I go over my maintenance and the erst of the days I stay on maintenance, then I start losing fat. Without going in deficit but by speeding up metabolism instead. So yes, it's definitely a good idea to include one. Either to do what I do, or to keep your metabolism high, or simply as a cheat day to keep you mentally satisfied when you diet. ^^

One or two days a week of higher cals is enough. You don't need to change cals every day. I think that the best is to keep it on schedule. You don't wanna confuse your body, that's not the point. The point is to keep your metabolism high.
