Abstract

Efficacy and safety of a weight-­‐loss formula (LeanSpa, Orange, CT) designed to increase metabolism, improve appetite, and influence hormonal balance positively in order to deplete excess body fat while preserving fat-­‐free mass (FFM) and bone mineral density (BMD) was assessed in an open-­‐label, single-­‐group study. This was performed using conditions that closely resembled those under which consumers would most likely use the formula. The formula consisted of chromium, 5-­‐hydroxytryptophan, iodine, natural caffeine, octopamine HCL and extracts of Garcinia cambogia, green tea, and acai berry. Efficacy, assessed in 20 over-­‐weight adults enrolled in a 60-­‐day regimen, focused on changes in dual energy x-­‐ ray absorptiometry-­‐-­‐derived body composition and resting metabolic rates (RMR). Safety was assessed by analyses of a 40-­‐item clinical chemistry panel, vital signs, and daily tracking reports of appetite control, adverse events, and self-­‐reported quality of life. Over two-­‐months, subjects lost an average of 3.8 lbs of body fat (P <0.0003) while gaining 1.3 lbs of fat-­‐free mass (FFM) (P=0.054). BMD increased, but statistical significance was not reached. Total % body fat was reduced -­‐1.7% (P=0.0017); and abdominal fat, by -­‐1.7% (P=0.0035). At mid-­‐study, RMR increased 7.5% (P=0.0165) and remained elevated until the end. While self-­‐reported appetite control increased from baseline to end of study (P=0.042), no significant changes were found in blood pressure, resting heart rate, and daily self-­‐ratings of adverse/positive effects. These results suggest the potential for formulas designed to have a multi-­‐ mechanistic effects (increase metabolism, aid eating control, better hormonal balance) to improve body composition by facilitating loss of excess body fat without concomitant adverse effects on FFM and BMD.
