Suzanne Somers

And how can a person forget her flab-fighting Thighmaster?

Maybe her biggest mark has been her approach to dieting. With more than 13 books under her belt, Somers has put much of her emphasis on the Somersize program - having published seven books on the plan over the last decade. Divided into two stages, the weight-loss phase is more restrictive of carbohydrates than the maintenance phase. The plan averages 1,200 calories each day.

There is nothing fluffy about this diet regimen that says to eat foods rich in fat and low in refined carbs. Load up your plate with fish, steak, chicken, butter and cream. There is also room for low-starch vegetables, whole grain pastas, nonfat dairy products and fresh fruits.

Somers endorses a diet that is low in carbs and high in proteins. While it may mimic other popular, low-carb plans such as Atkins, she puts her own spin on things. For example, Somers is a huge advocate of food-combining, a process by which different categories of food should not be eaten together. The plan is like a combination of low-carb eating and food combining. Eat liberally but abide by Somers' super seven rules for achieving success.
