Group Intervention Description Dietary Supplements and TR90 Eating Plan Dietary Supplements and TR90 Eating Plan Supplement A Powder Mix Days 1 - 15, (1 packet mixed in water or favorite beverage once a day) Supplement B Days 1 - 90, (1 capsule taken three times a day with a meal) Supplement C Days 1 - 90, (2 capsules taken with morning and evening meal) Experimental group will be instructed to consume every day, dietary supplements and a moderate protein eating plan delivering approximately 1200-1500 Kcals. Placebo and Low Fat Eating Plan Placebo and Low Fat Eating Plan Placebo Supplement A Powder Mix Days 1 - 15, (1 packet mixed in water or favorite beverage once a day) Placebo Supplement B Days 1 - 90, (1 capsule taken three times a day with a meal) Placebo Supplement C Days 1 - 90, (2 capsules taken with morning and evening meal) The placebo group will be instructed to consume every day, a low fat standard of care eating plan delivering approximately 1200-1500 Kcals.
- Primary Outcome Measures
Name Time Method Determine the effect of a novel weight management program on body fat mass over 90 days. Days 0 and 90 Evaluate changes in body measurements (weight and BMI; arm, waist, hip, thigh, claf, and ankle circumferences) and body composition (fat mass, fat free mass, % body fat) by Dual Energy X-ray Absorptiometry (DEXA) scanner.
- Secondary Outcome Measures
Name Time Method Determine the safety of novel weight management program (CBC, Comp. metabolic, lipid panel, heart rate, blood pressure and adverse events) Throughout 1 year Evaluate the changes in gene expression from the baseline visit to day 90. Day 0 and 90 Full gene arrays will be made on peripheral blood mononuclear cells. The gene expression changes will be made at baseline and day 90. There will also be a comparison back to proteins (i.e. hormones and inflammatory markers).
Determine skin carotenoid (Biophotonic Scanner) measurement changes. Throughout 1 year Biophotonic Scanner utilizes raman spectroscopy to determine skin carotenoid concentrations.
Evaluate resting energy expenditure and substrate utilization from baseline to days 90, 180, and 365. Days 0, 90, 80, and 365 Resting metabolic rate (RMR)and substrate utilization (R-values to determine wheather subjects are utilizing more fats or carbohydrates to meet energy demands) will be measured by CPET Quark.
Determine subjective measurements of hunger and appetite from standardized questionnaires (IWQOL Hunger/Appetite and overall wellbeing) Throughout 1 year Evaluate the changes in metabolism and appetite hormone levels from the baseline visit to day 90. Days 0 and 90 Leptin, Insulin, Adiponectin, Pancreatic Polypeptide, gLP1, C-peptide, Glucagon, Resistin and HbA1c
Evaluate changes in body measurements (weight and BMI; arm, waist, hip, thigh, claf, and ankle circumferences) and body composition (fat mass, fat free mass, % body fat) by Dual Energy X-ray Absorptiometry (DEXA) scanner. throughout 1 year Evaluate the changes in inflammatory markers from the baseline visit to day 90. Days 0 and 90 hsCRP, IL-6 and TNF Receptors 60 and 80
