Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Exercise Only Group (EX)

Participants will only receive the exercise protocol without nutrition education or counseling and instructed to continue to consume their regular diet.

Group Type EXPERIMENTAL

Exercise Protocol

Intervention Type OTHER

The exercise protocol consists of a nine-week progressive intense-conditioning program involving six consecutive days (Monday-Saturday) of one-hour exercises and one-day rest weekly for a total of 54 days of exercise. Exercises are performed in person as a group with other participating subjects and lead by certified instructors. Exercises will involve a variety of activities ranging from running, cycling, whole-body functional movements, power movements, and open-chain weight lifting with barbells and resistance bands.

Exercise with CR-LC Group

Participants will receive the exercise protocol and CR-LC Diet regimen.

Group Type EXPERIMENTAL

Exercise Protocol

Intervention Type OTHER

The exercise protocol consists of a nine-week progressive intense-conditioning program involving six consecutive days (Monday-Saturday) of one-hour exercises and one-day rest weekly for a total of 54 days of exercise. Exercises are performed in person as a group with other participating subjects and lead by certified instructors. Exercises will involve a variety of activities ranging from running, cycling, whole-body functional movements, power movements, and open-chain weight lifting with barbells and resistance bands.

Calorie-Restrictive Low Carbohydrate Diet (CR-LC)

Intervention Type OTHER

Consists of weekly nutrition plans, counseling and monitoring by on-site registered dietitians and nutritionists for nine weeks. CR-LC consists of caloric and macronutrient restrictions. Caloric restrictions involves a 40% deficit from calculated total daily energy expenditure. Macronutrient restriction involves a high protein, low carbohydrate diet (35% protein, 25% carbohydrate and 40% fat).

Exercise with Ancestral Diet (AD) Group

Participants will receive the exercise protocol and AD regimen.

Group Type EXPERIMENTAL

Exercise Protocol

Exercises will involve a variety of activities ranging from running, cycling, whole-body functional movements, power movements, and open-chain weight lifting with barbells and resistance bands.

Ancestral Diet (AD)

Intervention Type OTHER

Consists of weekly nutrition plans, counseling and monitoring by on-site registered dietitians and nutritionists for nine weeks. AD consists of consuming only whole foods and avoiding processed foods. Emphasis will be on food quality with no caloric or macronutrient restrictions.
