Jessica lost a total of 70 pounds, reported UPI on March 6.
So what's her diet like? Weight Watchers provides members with a points plan that assigns specific numbers to different types of foods. Depending on the member's needs (age, height, goal weight, current weight), specific points allowances are given. And some foods are "free," such as most vegetables.
Weight Watchers also has a variety of cookbooks available: Learn more including a recipe for Spicy Oven-Fried Chicken by clicking here.
In addition, Jessica boosted her metabolism and burned extra calories with regular workouts, according to Women's Health magazine. Her exercise plan:
- 45-minute resistance training workouts three times a week with a personal trainer
- walking four miles a day, using a pedometer to clock her steps and keep her motivated
"Walking is great exercise," commented sports nutritionist Nancy Clark, author of "Nancy Clark's Sports Nutrition Guidebook."
"You can do it in small increments and build it into your lifestyle."
A one mile walk burns 100 calories for women who weigh between 120 to 150 pounds. As for the pedometer, Jessica's personal trainer Harley Pasternak is a believer in this fat-burning booster.
In his book "The Body Reset Diet: Power Your Metabolism, Blast Fat, and Shed Pounds in Just 15 Days," Harley says that wearing a pedometer each day encourages you to take more steps and move more.
In addition, a Stanford University study showed that pedometer wearers took about one mile extra each day. Learn about the newest wearable step tracking devices by clicking here.
