简要总结
Overweight, physically inactive but otherwise healthy adults habitually eating a traditional Western diet will follow an ad libitum self-administered Paleo diet for 8-weeks. Blood and body composition will be measured before and after the intervention period.
详细描述
The Paleo diet is a dietary method that is gaining popularity among the general population due to potential weight loss and disease prevention benefits. The feasibility of the Paleo diet and the effectiveness of self-administration in improving cardiometabolic disease risk factors remains uncertain. Examination od cardiometabolic disease risk factors in overweight, physically inactive adults before and after 8-weeks of an ad libitum self-administered Paleo dietary intervention. Methods: Overweight, physically inactive but otherwise healthy adults habitually eating a traditional Western diet follow an ad libitum self-administered Paleo diet for 8-weeks. Blood samples were analyzed for fasting cardiometabolic disease biomarkers. Participants complete three-day dietary recalls prior to, and during weeks 4 and 8 of the intervention to confirm Western diet consumption at pre-, track compliance, and to assess dietary changes.
