Occurrence of obesity and its associated metabolic disorders continues to escalate. The present study evaluates the anti-obesity effects of ethanolic fruit extract of Terminalia chebula (EETC) on high fat diet induced obese mice. The bioactive compounds present in the EETC is evaluated by Fourier-transform infrared (FT-IR), Gas chromatography-mass spectrometry (GC-MS), and Liquid chromatography-mass spectrometry (LC-MS) analysis. The effects of EETC on energy intake, glucose tolerance, and various biochemical parameters were analyzed using laboratory mice. Relative gene expression of Fatty acid synthase (FAS), Peroxisome proliferator-activated receptors (PPAR ), Carnitine palmitoyltransferase-1 (CPT-1), Tumor necrosis factor alpha (TNF-) as well as Interleukin 6 (IL-6) were analyzed in liver and adipose tissues. The findings reveal the hypolipidemic and anti-obesity potential of EETC on high fat fed obese mice. EETC exerts its anti-obesity effects by suppressing lipogenesis through reduction in lipogenic enzyme (FAS) expression, increased fatty acid oxidation via PPAR and CPT-1 and by triggering the anti-inflammatory responses. To our knowledge, this is the first report of the effect of EETC on PPAR and CPT-1 in in vivo.

Taste sensation enables humans to make nutritionally important decisions such as food preference and consumption. It functions as deterministic factors for unpropitious eating behavior, leading to overweight and obesity. The hedonistic feeling on consumption of fat and sugar-rich meals, in particular, has a negative influence on health. In addition, impairment in the taste receptors alters the downstream signaling of taste transduction pathway. Hence, genetic polymorphism in typical taste receptors is a predictor of taste sensitivity variance across individuals. The present review summarizes the effect of a single nucleotide polymorphism (SNP) in sweet taste receptors (T1R2/T1R3) on taste perception among individuals of various body mass index (BMI). Furthermore, in the context of obesity, we discussed the possibility of crosstalk between fat and sweet receptors as well as taste dysfunction in diseased individuals. In overall, a greater understanding of the physiological relationship between taste receptors, altered taste sensitivity, and genetic polymorphisms should lead to more effective obesity prevention approaches.
