- Registration Number
- NCT03093792
- Lead Sponsor
- Texas A&M University
- Brief Summary
The purpose of this study is to look at the effects of a carbohydrate restricted, high protein, high fat diet on weight loss and health outcomes in women participating in the Curves Fitness and Weight Loss Program.
- Detailed Description
The purpose of this study is to determine if a carbohydrate restricted, high protein, high fat diet (20% carbohydrate, 45% protein, 35% fat; CC-II) promotes more favorable changes in weight loss and health outcomes compared to a traditional high carbohydrate, low protein, low fat diet (55% carbohydrate, 15% protein, 30% fat; AHA) and the Curves moderate carbohydrate restricted, high protein, and low fat diet (30% carbohydrate, 45% protein, 25% fat; CC-I).
