A Study to Investigate the Effect of 7-Keto on Resting Metabolic Rate in Overweight Adults

This study will investigate the effect of two different doses of 7-Keto compared to placebo on resting metabolic rate. One third of subjects will be given the lower 7-Keto dose, one third will be given the higher 7-Keto dose and one third will be given the placebo.
