Obesity and diabetes are two of the most prevalent health conditions in industrial nations. Recent studies suggest that a gut derived peptide, gastric inhibitory polypeptide (GIP), may be involved in the pathogenesis of type 2 diabetes and obesity induced by overnutrition. 2 The “thrifty genotype” hypothesis suggests that those who are prone to obesity have been favoured by natural selection in...
Diabetes has become one of the largest public health problems to date. Decreased physical activity, overnutrition, and nutrition transitions caused by changes in lifestyle contribute to the increasing incidence of chronic metabolic diseases as well as deaths related to them. The shift from undernutrition to overnutrition indicates that chronic diseases of affluence have become a public health p...
Known mutagens and carcinogens in the diet were compiled and the risk of cancer was estimated on the basis of average exposure levels in Switzerland and carcinogenic potencies from rodent bioassays. The analysis showed that, except for alcohol, the sum of all known dietary carcinogens could only explain a few percent of the cancer deaths attributed by epidemiologists to dietary factors. The dis...
Central regulation of metabolic physiology is mediated critically through neuronal functions; however, whether astrocytes are also essential remains unclear. Here we show that the high-order processes of astrocytes in the mediobasal hypothalamus displayed shortening in fasting and elongation in fed status. Chronic overnutrition and astrocytic IKKβ/NF-κB upregulation similarly impaired astrocyti...
On the basis of 3 comparable population-based surveys conducted in Brazil, we identified clear changes in the relative magnitude of women's undernutrition and overnutrition. In 1975, there were almost 2 cases of underweight to 1 case of obesity, whereas in 1997, there were more than 2 cases of obesity to 1 case of underweight. In 1997, Brazilian low-income women were significantly more suscepti...
This study aimed to examine the prevalence and trends of overweight, obesity and undernutrition in recent decades in India. Based on a systematic literature search on PubMed and other data sources, most published studies were regional or local surveys in urban areas, while good representative data from the India National Family Health Surveys (NFHS, 1992-1993, 1998-1999 and 2005-2006) allowed f...
Weight loss treatments include diets, drugs, physical training, and surgery, namely bariatric or obesity surgery. The current standard for bariatric surgery is gastric bypass. There are common beliefs that gastric bypass induces body weight loss because of a reduced food intake and that high-fat diet induces overweight and obesity because of overnutrition. The principal aim of the studies on ra...
Overnutrition may lead to obesity. Maternal obesity may affect fertility not only via anovulation, but also through direct effects on oocytes and preimplantation embryos, indicating that the periconceptional period is sensitive to conditions of overnutrition. The periconceptional period includes from folliculogenesis to implantation. Animal model studies suggest that oocytes derived from obese ...
