- Brief Summary
The study evaluated and compared the safety, tolerance and acceptability of a lifestyle modification program with or without nutritional supplementation in generally healthy overweight subjects with cardiometabolic risk factors.
- Detailed Description
To investigate the safety, tolerance and acceptability of a low-glycemic load diet combined with exercise and lifestyle modification education (DIET) or a similar program with a meal replacement formula and targeted nutraceuticals (PROG) in generally healthy, overweight subjects, forty to fifty subjects with two or more cardiometabolic risk factors, aged 18 to 69 will be randomized into different arms, 13-week intervention trial. To evaluate safety and tolerability, questionnaires were collected weekly. Additionally, baseline, week 9 and 13 fasting blood samples will be drawn for blood counts, metabolic profiles, plasma lipids, and additional cardiovascular risk factors. Vitals signs, weight and body composition were monitored weekly.

- Target Recruitment
- 44
Generally healthy subjects (men and women ≥ 18 and ≤ 69 years old) were required:
- to be overweight or obese (BMI ≥ 27 kg/m2 and ≤ 50 kg/m2),
- to exhibit visceral obesity (waist circumference ≥ 35 inches for women and ≥ 39 inches for men),
- and demonstrate signs of cardiometabolic dysfunction. Specifically, subjects were required to have:
- elevated LDL cholesterol ≥ 130 mg/dl
- and/or elevated TG defined as TG ≥ 130 mg/dl. Additionally, subjects were required to have at least one of the following criteria (unless subject had both elevated LDL and TG):
- HDL < 50 mg/dl for women and < 40 mg/dl for men,
- blood glucose ≥ 100 mg/dl, HbA1C ≥ 5.7%,
- or Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) score defined as ≥ 2.0.
Exclusion Criteria included:
- Pregnancy
- Lactation
- Recent changes in prescription medications, over-the-counter medications, medical foods, and nutritional supplements
- Recent or regular use of narcotics, investigational drugs, corticosteroids, anticoagulants, neuroactive medications, or medication or supplements relevant to hyperglycemia or hyperlipidemia
- Chronic use of over-the-counter medication which would interfere with study endpoints including NSAIDS, laxatives and antacids
- Allergy or intolerance to study products
- Serious, unstable medical conditions including known infection with HIV, tuberculosis or hepatitis; cardiovascular disease; Diabetes Mellitus; autoimmune diseases; malignancy; psychiatric disease; substance abuse;
- Abnormal laboratory findings
- Participating in or planning to begin a weight loss diet during the study period
- Difficulty in swallowing pills
- Lifestyle or schedule incompatible with the study protocol.

- Primary Outcome Measures
Name Time Method Number of participants with treatment-related adverse events as assessed by CTCAE v4.0". 13 weeks Data collection including questionnaires at individual and group visits and physician interviews at individual visits (baseline, week 9 and week 13) will be used to assess participants for treatment-related adverse events.
- Secondary Outcome Measures
Name Time Method Number of participants with treatment-related changes in basic safety labs 13 weeks Phlebotomy will be conducted at individual visits (baseline, week 9 and week 13). Comprehensive Metabolic Panels and Complete Blood Counts will be assessed for treatment-related change from baseline.
Number of participants with treatment-related changes in vital signs 13 weeks Blood pressure and peripheral pulse will be monitored at individual visits (baseline, week 9 and week 13). Collected data will be assessed for treatment-related change from baseline.
Change in body fat in percentage compared to baseline 13 weeks Body fat in percentage will be monitored (Tanita body composition monitor) at individual visits (baseline, week 9 and week 13) and group visits. Collected data will be assessed for treatment-related change from baseline. Comparison will be made between DIET and PROGRAM arms.
Change in fasting insulin in mIU/l compared to baseline 13 weeks Fasting insulin in mIU/l will be measured at individual visits (baseline, week 9 and week 13). Collected data will be assessed for treatment-related change from baseline. Comparison will be made between DIET and PROGRAM arms.
Change in BMI in kg/m2 compared to baseline 13 weeks BMI in kg/m2 will be monitored (Tanita body composition monitor) at individual visits (baseline, week 9 and week 13) and group visits. Collected data will be assessed for treatment-related change from baseline. Comparison will be made between DIET and PROGRAM arms.
Change in Total Cholesterol in mg/dl compared to baseline 13 weeks Total Cholesterol in mg/dl will be measured at individual visits (baseline, week 9 and week 13). Collected data will be assessed for treatment-related change from baseline. Comparison will be made between DIET and PROGRAM arms.
Change in oxidized LDL-Cholesterol in mg/dl compared to baseline 13 weeks Oxidized LDL-Cholesterol in mg/dl will be measured at individual visits (baseline, week 9 and week 13).

Change in Metabolic Syndrome Score compared to baseline 13 weeks A Metabolic Syndrome score (0-5) will be calculated for participants at individual visits (baseline, week 9 and week 13). The five features of Metabolic Syndrome (visceral adiposity based on waist circumference, hyperglycemia, hypertension (or use of antihypertensives), hypertriglyceridemia and low HDL-Cholesterol will each be assigned a point value of 1. Subjects will receive 1 point for each feature they demonstrate on collected data. Score will be assessed for treatment-related change from baseline. Comparison will be made between DIET and PROGRAM arms.
Change in LDL-Cholesterol in mg/dl compared to baseline 13 weeks LDL-Cholesterol in mg/dl will be measured at individual visits (baseline, week 9 and week 13). Collected data will be assessed for treatment-related change from baseline. Comparison will be made between DIET and PROGRAM arms.
