An Examination of a Weight Loss Formula on Health (NB14)

An Examination of a Novel Weight Loss Formula on Anthropometry and Indices of Cardiovascular Disease Risk

The aim of this study is to examine a novel weight loss formula with and without common stimulants on anthropometry and indices of cardiovascular disease risk.

Study Overview

• Status: Completed
• Conditions: Weight Loss
• Intervention / Treatment: Dietary supplement: Active with caffeine; Dietary supplement: Active without caffeine; Dietary supplement: Placebo

Detailed Description

Obesity remains a problem for overall health and risk for cardiovascular disease worldwide. While dietary modification and increased levels of physical activity remain steadfast recommendations, alternative strategies related to supplementation remain an interest for the general populace and medical communities. A potential objection to the use of dietary supplements is that they often contain stimulants designed to increase metabolism. However, consumers and health practitioners alike are wary of such formulae; hence, the continued investigation of non-stimulant supplements is warranted. Therefore the aim of this study is to examine a novel weight loss formula with and without common stimulants on anthropometry and indices of cardiovascular disease risk.
