Nelson recommends cardio to lose the weight along with pilates and strength training to tone your belly.
The book does say exercise will certainly bring results faster, but it's not required.
The diet's magic ingredient is a diet rich in MUFAS or monounsaturated fatty acids. They come in five categories: oils, olives, nuts and seeds, avocados and dark chocolate.
"There's not enough research to support that, unfortunately," she said.

Other causes of beefy bellies include:
- consuming too much alcohol
- too much fast food
- sugar alcohols found in fat free candy
- and chewing gum, which can push air into your stomach
"That's a tidbit a lot of people are not aware of," Fowler said.
