When I was growing up my mother would do the Rotation Diet whenever she needed to lose a few pounds. I don't know what her calorie count was, but I remember she would follow it for a week or two rotating through a three day cycle. I now do it periodically and eat 800 one day, 1000 the next and 1200 the third and then repeat the rotation. I read this article about a similar concept called intermittent fasting. One version, eat only 500 to 600 calories on two nonconsecutive days and eat normal the other days. Another option normal one day, next mini-fast, and third day only eat during certain hours. Some people are very strict six days and then take Sunday off. This type of eating plan doesn't work for everyone, especially people with diabetes, etc. I think it works for some people because is switches things up and keeps our metabolism confused.
