A diet where you can eat whatever you want and lose weight? "There's no food that's off limits, absolutely none, there's no deprivation," Jorge Cruise, celebrity trainer and author of "The Cruise Control Diet," told Inside Edition.

"It's really understanding that you can enjoy fasting without starvation," Jorge said.
