Brief Summary:
Obesity is pro-inflammatory, impairs metabolism, and physically limiting. Specifically, muscle in obese persons does not synthesize proteins normally. This further increases metabolic and physical dysfunction. As such, obesity programs should not only focus on weight loss, but muscle metabolic health. Dairy nutrients have anti-inflammatory and anabolic properties, but mostly evaluated in isolation and/or pre-clinical designs. Also, it is unknown if the circulating benefits extend to the muscle. We hypothesize that dairy full-fat milk will improve these obesity characteristics.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 44 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Dairy Food Consumption and Its Effects on Inflammation and the Postprandial Regulation of Muscle Protein Synthesis
Estimated Study Start Date : January 2020
Estimated Primary Completion Date : January 2021
Estimated Study Completion Date : January 2022

Arm Intervention/treatment
Experimental: Full-fat dairy
3x daily servings (cup-eq) of full-fat (3.25%) commercial cow's milk.
Dietary Supplement: Diet-controlled intervention
1-week weight-maintenance diet-controlled intervention.

Active Comparator: Non-fat diary
3x daily servings (cup-eq) of non-fat (0%) commercial cow's milk.
Dietary Supplement: Diet-controlled intervention
1-week weight-maintenance diet-controlled intervention.

Placebo Comparator: Non-dairy control
3x daily servings (cup-eq) of non-dairy sourced macronutrient composition of full-fat milk.
Dietary Supplement: Diet-controlled intervention
1-week weight-maintenance diet-controlled intervention.

Primary Outcome Measures :
  1. Compare fractional synthesis rate of myofibrillar protein to different dairy matrices [ Time Frame: 0-5 hours postprandial observation period to ingesting 2 servings of respective Arm ]
    Rate of building new proteins in skeletal muscle contractile protein fraction after a meal

  2. Compare concentration of inflammation markers in the blood to different dairy matrices [ Time Frame: 1 week observation period to respective Arm within a weight-maintenance diet ]
    Measurement of blood cytokines, monocytes, and macrophages before and after a diet intervention.
