Outcome Measures

Primary Outcomes (1)

  • Change in Plasma Fatty Acid Composition and Lipoprotein Analysis

    Blood analysis for Fatty Acid Composition and Lipoproteins will by conducted by Lipid Technologies and Quest Diagnostics, respectively.

    Through study completion, an average of 2 years.

Secondary Outcomes (3)

  • Change in Body Composition as Assessed by DEXA and MRI

    Through study completion, an average of 2 years.

  • Change in Blood-based Inflammation Markers

    Through study completion, an average of 2 years.

  • Change in Blood Metabolite Profiles

    Through study completion, an average of 2 years.

Study Arms (4)

High Carbohydrate No Cheese

EXPERIMENTAL

Intervention: Nutritional and Dietary Manipulation. This arm will be provided food with an approximate macronutrient breakdown of: 55% CHO, 20% PRO and 25% fat with \~6oz Cheese (gouda or cheddar) per day being used as a fat source.

Other: Nutritional and Dietary Manipulation

High Carbohydrate High Cheese

EXPERIMENTAL

Intervention: Nutritional and Dietary Manipulation. This arm will be provided food with an approximate macronutrient breakdown of: 55% CHO, 20% PRO 25% and Fat 25% with \~6oz Cheese (gouda or cheddar) per day being used as a fat source.

Other: Nutritional and Dietary Manipulation

Mod. Carbohydrate High Cheese

EXPERIMENTAL

Intervention: Nutritional and Dietary Manipulation. This arm will be provided food with an approximate macronutrient breakdown of: 30% CHO, 20% PRO and 50% Fat with \~6oz Cheese (gouda or cheddar) per day being used as a fat source.

Other: Nutritional and Dietary Manipulation

Low Carbohydrate High Cheese

EXPERIMENTAL

Intervention: Nutritional and Dietary Manipulation. This arm will be provided food with an approximate macronutrient breakdown of: 10% CHO, 20% PRO and 70% Fat with \~6oz Cheese (gouda or cheddar) per day being used as a fat source.

Other: Nutritional and Dietary Manipulation

Interventions

Participants will undertake a controlled feeding intervention. All food will be prepared and delivered to participants by research staff. Participants will be asked to exclusively eat what is provided to them in efforts to control any dietary effects.
