Rationale of the "BIO-OHS" study (Prevalence of Obesity Hypoventilation Syndrome): The overall prevalence of Obesity Hypoventilation Syndrome (OHS) has never been directly assessed in the general population. Actually, this prevalence has been assessed in patients referred to sleep clinics with a potential diagnosis of sleep-disordered breathing or in patients already diagnosed with sleep apnea. The purpose of this study is to determine the prevalence of Obesity Hypoventilation syndrome in obese patients referred to clinical laboratories for regular follow-up medical analysis.

Effects of foods or food substances on energy expenditure are of particular interest, because of the increasing prevalence of obesity and its consequent metabolic diseases like type II diabetes and fatty liver disease, all risk factors for the development of cardiovascular diseases (CVDs). Recently, the Goji berry (Lycium Barbarum, wolfberry) was introduced into the Western diet. L. Barbarum originates from Asia, where it is used to improve the health of several organs. Although L. Barbarum is promoted as a super food with many beneficial effects, consistent scientific evidence for these effects is lacking. In one study, it was found that short-term intake of L. Barbarum polysaccharides - equal to 150 g of fresh berries - increased postprandial oxygen consumption. This indicates that L. Barbarum might exert beneficial effects on energy expenditure. Furthermore, long-term intervention trials have shown beneficial effects of L. Barbarum on lipid and glucose metabolism in mice and type II diabetic patients and on inflammatory status in healthy elderly. Altogether, L. Barbarum has the potential to be used as a functional food to increase metabolic health, but detailed information on the postprandial effects of L. Barbarum is missing. We therefore propose this double-blinded, randomized, placebo controlled intervention trial to investigate the effect of a single dose of L. Barbarum on postprandial energy expenditure substrate oxidation, metabolic flexibility, lipid and glucose metabolism and inflammatory markers.
