This is an excerpt from a Personal Trainer on why weekly cheat meals help break plateaus and keep our metabolic engine revving.
When you are dieting and in a submaintenance level for a prolonged time your metabolism, thyroid production, and leptin levels down regulate and this is usually when weight stalls or there is performace issues during training. The first thing people do on plateaus is reduce calories which actually makes things worse and causes your body to start storing fat to survive and you damage your metabolic rate as well. So when you cheat (calorie spike) it up-regulates your leptin horomone , which controls thyroid, test levels and GH. This basically jacks everything up and your body starts burning fuel more efficiently again.
The thing is you shouldn't do this more than once every 7 days to make sure you need it and it works. This is very general as you really need to know how to read your body's bio-feedback to determine if a calorie spike is needed. Don't cheat just to cheat.
I DO personally find that after a good cheat meal (approx 16-17 ounces of take out Jamaican curried chix, rice & peas, steamed cabbage...my favorite cheat), that I do usually drop a few lbs when I'm on a stall/slow down phase.
How bout you? Do you have cheat meals? Cheat day? Discuss.
