Nature's Sunshine Products, Inc.44 enrolled

Overview

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.

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.

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.

Outcomes

Primary Outcomes

Number of participants with treatment-related adverse events as assessed by CTCAE v4.0".

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.

Time frame: 13 weeks

Secondary Outcomes

Number of participants with treatment-related changes in basic safety labs

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.

Time frame: 13 weeks

Number of participants with treatment-related changes in vital signs

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.

Time frame: 13 weeks

Change in weight in pounds compared to baseline

Weight in pounds 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.

Time frame: 13 weeks

Change in body fat in percentage compared to baseline

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.

Time frame: 13 weeks

Change in BMI in kg/m2 compared to baseline
