The article in the current issue of Hypertension by Aucott et al1 raises some interesting questions. Does weight loss in the long term (ie, 3 years) result in a decrease in blood pressure (BP) levels? Is there difference in the effect of weight loss on decreased systolic BP (SBP) versus diastolic BP (DBP)? They combined 8 clinical trials and 8 cohort studies and tried to evaluate the linear rel...

BACKGROUND & AIMS Leptin, the protein product of the ob gene, increases energy expenditure and reduces food intake, thereby promoting weight reduction. Leptin also regulates glucose homeostasis and hepatic insulin sensitivity via hypothalamic proopiomelanocortin neurons in mice. Roux-en-Y gastric bypass (RYGB) induces weight loss that is substantial and sustained despite reducing plasma leptin ...

OBJECTIVE Diabetes Prevention Program (DPP) participants randomized to the intensive lifestyle intervention (ILS) had significantly reduced risk of diabetes compared with placebo participants. We explored the contribution of changes in weight, diet, and physical activity on the risk of developing diabetes among ILS participants. RESEARCH DESIGN AND METHODS For this study, we analyzed one arm ...

OBJECTIVE To evaluate the impact of a diet and physical activity intervention (BeWEL) on weight change in people with a body mass index >25 weight (kg)/height (m)(2) at increased risk of colorectal cancer and other obesity related comorbidities. DESIGN Multicentre, parallel group, randomised controlled trial. SETTING Four Scottish National Health Service health boards. PARTICIPANTS 329 ov...

Background Weight loss usually decreases energy expenditure (EE) because of changes in body composition (BC). The reduction in EE may contribute, in part, to long-term weight regain. Patients undergoing bariatric surgery might experience a decrease in EE, mainly due to reduced resting metabolic rate (RMR), explained by a decreased lean body mass (LBM), similarly to what occurs to patients after...

Spontaneously hypertensive rats were placed on weight-reducing diets either by limiting regular feedings to twice weekly or by providing half the normal ration daily. Significant reductions in body weight and blood pressure were observed at 2,4, and 6 weeks after beginning the diet. Blood pressure fell despite maintenance of a normal or elevated sodium intake indicating that the reduction was n...

Ketogenic diets have been used as an approach to weight loss on the basis of the theoretical advantage of a low-carbohydrate, high-fat diet. To evaluate the physiological and metabolic effects of such diets on weight we studied mice consuming a very-low-carbohydrate, ketogenic diet (KD). This diet had profound effects on energy balance and gene expression. C57BL/6 mice animals were fed one of f...

Abstract Overweight and obesity has increased in prevalence over the last two decades in many developed and developing countries including Iran. The aim of this present study was to compare the weight reduction effects of ketogenic and low calorie diets on overweight and obese Iranian children. Seventy-six overweight or obese children aged 9-16 years recruited from outpatient Ghaem Hospital, Nu...

A B S T R A C r The effects of obesity and caloric intake on biliary lipid metabolism were investigated in a series of related studies. The degree of saturation of gallbladder bile with cholesterol was found to be significantly higher in a group of 23 obese healthy subjects than in a group of 23 nonobese controls matched for age, sex, and race. Bile was also significantly more saturated in 11 o...
