Its effect on weight loss stems from its impact on insulin and glucose. The evidence supporting the use of weight-loss dietary supplements is limited, inconclusive, and unconvincing.

While our initial intentions were to include observational studies, the volume of studies, their design and outcomes, and the importance of limiting to RCTs, made this impossible. In those that did use appropriate methods or were of high quality, few were statistically significant, with findings not clinically significant. This includes increasing the sample size and study duration, but also evaluating both homogeneous and heterogeneous ethnic and age-appropriate cohorts.

However, in subgroup analyses, calcium did reduce body weight in some groups, including children, adolescents, adult men, premenopausal women, women older than 60, and people with normal BMI . These reviews include a 2009 evidence report from the Agency for Healthcare Research and Quality whose authors concluded that, overall, clinical trial results do not support an effect of calcium supplementation on weight . Most weight-loss supplements use chromium picolinate in daily dosages of 200 to 400 mcg. Chromium is thought to play a role in carbohydrate and lipid metabolism, potentially influencing weight and body composition.12 However, data on healthy persons without diabetes do not support this theory, and data on patients with diabetes are inconclusive.13 Ephedra products comprised only 0.8 percent of all dietary supplement sales in 2001, yet they were responsible for 64 percent of all herb-related adverse events reported to U.S. To counsel patients appropriately, physicians must be knowledgeable about the efficacy, safety, and quality of common weight-loss supplements.

Could a low-carb diet give you an edge in losing weight? According to an in-vitro study, P57 stimulates cholecystokinin secretion in human enteroendocrine cells, while cholecystokinin has been studied for insights into its appetite-suppressing effect through the vagus nerve. Research into the effects of P57 in vivo have shown that intraventricular injection of purified P57 in rats decreases food intake and significantly increases hypothalamic ATP production, which may decrease the appetite response. While the active compound causing the anorexigenic effect of Hoodia gordonii is not yet clear, P57AS3 (P57), an oxypregnane steroidal glycoside, is commonly considered to be the metabolite responsible for these effects 43-45.

Research indicates that CLA exists in multiple forms, with two primary isomers – c9,t11 and t10,c12 – showing the most promising effects on body composition.
