Nutritional fat is one of the most controversial topics in nutritional research, particularly against the background of obesity. Studies investigating fat taste perception have revealed several associations with sensory, genetic, and personal factors (e.g. BMI). However, neuronal activation patterns, which are known to be highly sensitive to different(More)
OBJECTIVE Obesity and type 2 diabetes mellitus (T2DM) are associated with altered food-related neuronal functions. Besides weight loss, substantial improvement of glucose metabolism in patients with T2DM can be achieved by bariatric surgery. We aimed to target the neuronal and behavioral correlates of improved glycemic control after bariatric surgery. (More)
BACKGROUND Besides its advantages, bariatric surgery implicates a risk of nutritional deficiencies, which might result in impaired bone metabolism. We assessed the effect of laparoscopic sleeve gastrectomy (LSG) on blood markers of bone metabolism in obese patients during a 3-year observation period. METHODS In 39 obese patients (29 women, 10 men, mean(More)
Multiple lines of research have demonstrated that humans can perceive fat in the form of free fatty acids (FFAs). However, the dietary concentration of FFAs is generally very low and fat is mainly consumed as triacylglycerol (TAG). The aim of this study was to examine the perception of different fatty stimuli and possible associations between them.(More)
