I don't know the specific science of it but I heard that when you've lowered calories for a deficit for a certain amount of time, you can hit a plateau where you stop losing weight/fat. It has to do with leptin levels according to what I've read. I had no idea about this. After a plateau, I ate half of a Little Caesars deep dish pizza (and loved every second) and still lost weight. Apparently the refeed boost leptin levels back up after being lowered on the deficit. It works! With my meal plan from a local company around here, I've been able to lose 10 pounds in less than 2 months. I hit a plateau but the refeed did the trick. That doesn't seem like much, but I have gotten stronger and I don't think I've lost any muscle. Anyway, have fun with your refeed!
