It's probably not going to come from someone called the "Bikini Chef."

“For my whole life I have strived to find a balance between staying slim and healthy and enjoying the fattening foods I love. People think that because I am The Bikini Chef being thin comes easy for me. It doesn’t,” says Chef Susan. “A few years ago I was stress eating and not exercising. I gained more weight than I ever have. So I made the commitment to get back on track. It wasn’t easy and it didn’t come quickly but I stayed with it and learned I could still eat my favorite foods but just make them ‘skinny.’”

While I'm sure Chef Susan "Bikini" Irby has some fine ideas about substitutions in her new cookbook "Substitute Yourself Skinny," there is really only one secret to losing weight. Are you ready? Here it comes: Eat less and move your fat ass more.

I just saved you the cost of one over-priced cookbook. You're welcome.
