Experimental: Curves Program
The Curves group will follow the high protein/low fat diet (30% carbohydrate, 45% protein, 25% fat) for 7-days at 1,200 kcals/day and then 1,500 kcals/day for the remaining 21-days of the 30-day diet period.
The participants will then consume a normal maintenance diet (2,200 kcals/d; 45% carbohydrate, 30% protein, 25% fat) for 30-days.
During the maintenance period, participants will diet for 2-days at 1,200 kcals/day if they gain 3 pounds of weight.
|
The Curves Circuit consists performing 13 hydraulic resistance exercise machines that utilize bidirectional resistance that work all major muscle groups.
These are interspersed with floor-based calisthenic exercises designed to maintain an elevated heart rate.

|
Experimental: Weight Watchers Momentum Program
This program is based on the Weight Watchers four pillar approach (food, exercise, behavior and support).
The Momentum Program uses POINTS values to help keep track of what you eat.
A POINTS "budget" will be personalized for you at the weekly meetings.
|
The Weight Watchers program encourages one to increase physical activity.
