The charity, Diabetes UK, has recently launched its Measure Up campaign, which focuses on the relationship between waist size, obesity and the likelihood of developing diabetes mellitus.
Two recent studies, the second of which is reported herein, provide evidence that genetic variation in the sweet receptor subunit, TAS1R3, and the second messenger, gustducin (GNAT3), affect the ability of people to correctly sort ascending concentrations of sucrose. These findings raise questions
Leptin, the product of the obese (ob) gene, is a hormone primarily produced in adipose cells, and also at smaller amounts in some other peripheral organs. It regulates food intake, energy expenditure, and body weight. Leptin is thought to promote weight loss, at least in rodents, by suppressing
BACKGROUND
Previous studies have suggested that patients who are defined as so-called sweet eaters have more difficulties to lose weight and to maintain weight loss after both conservative treatment and restrictive bariatric surgery, such as gastric banding. There is, however, no agreement on the
MicroRNAs (miRNAs) have recently been found to be critical regulators of metabolic homeostasis. A study in Nature by Trajkovski et al. (2011) shows that the highly related miRNAs miR-103 and miR-107 modulate insulin sensitivity and glucose homeostasis in obese mice. These miRNAs might represent
Taste hedonics drive food choices, and food choices affect weight maintenance. Despite this, the idea that hyper-palatability of sweet foods is linked to obesity development has been controversial for decades. Here, we investigate whether interpersonal differences in sweet-liking are related to body
Taste responses of normal-weight, obese, and formerly obese individuals for sucrose and fat containing stimuli were examined using a mathematical modelling technique known as the Response Surface Method. The subjects accurately rated intensities of sweetness, fatness, and creaminess of 20 different
Excess energy intake is recognised as a strong contributing factor to the global rise of being overweight and obese. The aim of this paper was to investigate if oral sensitivity to complex carbohydrate relates to ad libitum consumption of complex carbohydrate foods in a sample group of female
Fibroblast growth factor 21 (FGF21) is a hormone induced by various metabolic stresses, including ketogenic and high-carbohydrate diets, that regulates energy homeostasis. In humans, SNPs in and around the FGF21 gene have been associated with macronutrient preference, including carbohydrate, fat,
Vertical banded gastroplasty (VBGP) was compared with Roux-en-Y gastric bypass (RYGBP) in a randomized prospective trial that included preoperative dietary separation of "sweets eaters" versus "non-sweets eaters." Randomization was stopped at 9 months after 20 patients had undergone each procedure
This study compared 40 female participants in a behavioral weight loss program who frequently reported craving sweets to 40 who rarely reported craving sweets using 2-week behavioral eating diaries. The two groups were compared on physiological, demographic, and questionnaire measures and no
Serotonergic involvement has been implicated in preferential consumption of treat foods. We tested the effect of acute tryptophan depletion (ATD) on food consumption by overweight and lean adults with and without a history of recurrent major depressive disorder (MDD). ATD and taste-matched placebo
