Anyone ever hear of this diet?

A girl on my facebook did it. She says it worked for her but I haven't seen her in person for a while. Has anyone even heard of it. She said she did it because she stopped losing weight and it helped jump start her weight loss again.

I know a few people who did it. They gained it all back in 2 days.

Fad diets are terrible. Just eat healthy, watch your caloric intake, and exercise. Not that hard.

doesn't sound all that healthy =/ like they lost weight due to lack of food. i know if you don't eat enough for a while and then go back to eating regularly (even if its healthy) that you gain a lot of weight. happened to me when i worked 3rd shift. lost a lot of weight cause i wasn't eating much and then when i started eating the way i was supposed to i gained a lot of weight quickly. i know if you go to the gym at all sprinting is supposed to help with losing weight.
