The "Overnight Diet" claims you can lose weight while you sleep.
Dr. Caroline Apovian wrote a book about the diet, WMAR reported.
So how does it work? For six days you eat a high protein diet. On the seventh day, eat nothing but liquids.
Throw in some sleep and off comes the weight.
Critics say it's impossible to lose that much weight while sleeping. They say it's the equivalent of burning 6,000 or 7,000 calories and you can't do that while sleeping.
