Xellex is a unique patented complex of plant-based polysaccharides and esterified fatty acids to improve diet and exercise results. Designed to target Leptin, to reduce stored body fat and promote sustained weight loss by reducing propensity for insulin resistance and metabolic syndrome. Recent clinical studies showed evidence of Xellex's ability to improve the body's response to available leptin, providing ability to boost metabolism and burn calories increasing the body's energy production.* Xellex allows the body to avoid leptin resistance and continue to lose weight without the body's natural "starvation mechanism" counteracting the effect, therefore it can be concluded that the addition of Xellex would be beneficial to all weight loss protocols to sustain long term weight loss without the re-bound or 'yo-yo' effect. * (Eur J Appl Physiol (2009) 105:665-672 DOI 10.1007/s00421-008-0944-y)
