Concomitant changes in sleep duration and body weight and body composition during weight loss and 3-mo weight maintenance.

Background: An inverse relation between sleep duration and body mass index (BMI) has been shown.

Objective: We assessed the relation between changes in sleep duration and changes in body weight and body composition during weight loss.

Design: A total of 98 healthy subjects (25 men), aged 20-50 y and with BMI (in kg/m(2)) from 28 to 35, followed a 2-mo very-low-energy diet that was followed by a 10-mo period of weight maintenance.

Physiological response of adipocytes to weight loss and maintenance.

Background: Metabolic processes in adipose tissue are dysregulated in obese subjects and, in response to weight loss, either normalize or change in favor of weight regain.

Objective: To determine changes in adipocyte glucose and fatty acid metabolism in relation to changes in adipocyte size during weight loss and maintenance.

Methods: Twenty-eight healthy subjects (12 males), age 20-50 y, and BMI 28-35 kg/m(2), followed a very low energy diet for 2 months, followed by a 10-month period of weight maintenance.

No effects of Korean pine nut triacylglycerol on satiety and energy intake.

Background: Triacylglycerols (TAG) have been shown to have potential appetite suppressing effects. This study examined the effects of 3 g and 6 g Korean pine nut triacylglycerols (PinnoThin) on appetite and energy intake.

Methods: 130 g Isoenergetic yogurt containing either placebo (milk fat) or PinnoThin TAG was consumed as a breakfast, after an overnight fast, in a double blind randomized crossover design.

Effects of oligofructose on appetite profile, glucagon-like peptide 1 and peptide YY3-36 concentrations and energy intake.

In rats, oligofructose has been shown to stimulate satiety hormone secretion, reduce energy intake and promote weight loss. The present study aimed to examine the effect of oligofructose supplementation on appetite profiles, satiety hormone concentrations and energy intake in human subjects. A total of thirty-one healthy subjects (ten men and twenty-one women) aged 28 (SEM 3) years with a BMI of 24·8 (SEM 0·3) kg/m(2) were included in a randomised double-blind, cross-over study.
