Alarcon et al. (1) recently demonstrated that b-cell insulin secretory dysfunction is rapidly restored by exposure of islets to low-normal glucose ex vivo in db/db mice. The authors allude to the potential clinical relevance for “transient b-cell rest” in type 2 diabetes (T2D). Could transient b-cell rest be accomplished by manipulating diet? Lim et al. (2) have shown that a very low-calorie di...

BACKGROUND/AIMS Moderate maternal calorie-restriction during gestation programmes offspring for a major propensity to develop metabolic alterations in adulthood. We aimed to assess whether increased hepatic fatty-acid oxidation (FAO), at early ages, by gene transfer of Cpt1am (active mutant of carnitine palmitoyltransferase-1a), may be a strategy for reversing metabolic disturbances associated ...

Mammalian sirtuins have diverse roles in aging, metabolism and disease. Recently we reported a new function for SIRT5 in urea cycle regulation. Our study uncovered that SIRT5 localized to mitochondria matrix and deacetylates carbamoyl phosphate synthetase 1 (CPS1), an enzyme which is the first and rate-limiting step of urea cycle. Deacetylation of CPS1 by SIRT5 resulted in activation of CPS1 en...

A 33 year old man presented with biliary colic and transient obstructive jaundice. In the 4 weeks preceding admission he had been taking a very low calorie diet (the Cambridge Diet) and celebrated achieving his target weight with a fatty meal on the morning of admission. An ultrasound of the gallbladder suggested biliary sludge. We suggest that he developed the biliary sludge as a consequence o...

OBJECTIVE This is an Asian study, which was designed to examine the correlations between biochemical data and food composition of diabetic patients in Taiwan. METHODS One hundred and seventy Taiwanese diabetic patients were enrolled. The correlations between biochemical data and diet composition (from 24-hour recall of intake food) of these patients were explored (Spearman correlation, p < 0....

Background: Obesity can cause leptin and insulin resistance which will affect the production of GnRH FSH. One risks factor obesity is high calorie intake chronicaly. Exercise plays a role in regulation blood body weight. However, effect exercise on subjects with high-calorie diet FSH unknown. This study aims to determine moderate intensity interval training (MIIT) level female rats. Method: Sam...

OBJECTIVE The investigation of the relationship between high density lipoprotein (HDL) and adiponectin. DESIGN Thirty-seven obese or overweight [body mass index ≥27 Kg/m(2)], hypertriglyceridemic patients underwent one of the following interventions for 3 months: 1) Low-calorie diet (n=19), 2) Low-calorie diet plus fenofibrate (n=18). RESULTS Circulating total adiponectin did not change sig...

Background & Aims: Nonalcoholic steatohepatitis (NASH) is part of nonalcoholic fatty liver disease (NAFLD). No special medical treatment is known for this disease, and lifestyle modification is the best known method of treatment. We aimed to compare the effect of diet and aerobic exercise with that of diet alone on the quality of life of patients with NASH. Methods: In the present study, 25 pat...

Dietary restriction (DR) extends life span in diverse organisms, including mammals, and common mechanisms may be at work. DR is often known as calorie restriction, because it has been suggested that reduction of calories, rather than of particular nutrients in the diet, mediates extension of life span in rodents. We here demonstrate that extension of life span by DR in Drosophila is not attribu...

BACKGROUND Although the Health & Fitness category of the Apple App Store features hundreds of calorie counting apps, the extent to which popular calorie counting apps include health behavior theory is unknown. OBJECTIVE This study evaluates the presence of health behavior theory in calorie counting apps. METHODS Data for this study came from an extensive content analysis of the 10 most popu...
