OBJECTIVE It is unclear if resting metabolic rate (RMR) and spontaneous physical activity (SPA) decrease in weight-reduced non-obese participants. Additionally, it is unknown if changes in SPA, measured in a respiratory chamber, reflect changes in free-living physical activity level (PAL). RESEARCH METHODS AND PROCEDURES Participants (N = 48) were randomized into 4 groups for 6 months: calori...

Abstract The present study aimed at determining the effects of dietary DL-methionine supplementation on water quality, bioflocs composition and Nile tilapia juvenile’s (initial body weight = 2.76 ± 0.06 g) growth performance in BFT rearing tanks (18 fish/100-L tank). Fish were or not subjected to artificial feed restriction. experimental treatments consisted two control groups: 1 - no restricti...

Our objectives were to evaluate maternal body changes in response to dietary restriction or the increased nutrient requirement of fetal growth. In Exp. 1, 28 mature crossbred ewes (61.6 +/- 1.8 kg initial BW) were fed a pelleted forage-based diet to evaluate effects of pregnancy and nutrient restriction on visceral organ mass. Treatments were arranged in 2 x 3 factorially, with dietary restrict...

BACKGROUND Polycystic ovary syndrome (PCOS), a common condition in women, improves with weight loss. Meal replacements in short-term weight loss and strategies for weight maintenance have not been investigated in PCOS. OBJECTIVE We compared in overweight women with PCOS the effects of meal replacements in short-term weight-loss and longer-term carbohydrate- or fat-restriction strategies on we...

Abstract The study objective was to evaluate the effect of single and/or extra doses vitamin C (VC) on water-restricted (WR) Xhosa goats, by evaluating their intake, digestibility, nitrogen, and mineral balance during summer. Goats (42) were randomly divided into seven groups: GI (control, received ad libitum water daily), GII (WR-70% lib. ), GIII (WR-50% GIV + VC [3 g/day orally]), GV GVI oral...

The rewarding effect produced by electrical stimulation of some lateral hypothalamic sites is modulated by chronic food restriction and weight loss. The sensitivity of the rewarding effect to restriction predicts the modulation of brain stimulation reward (BSR) by the adiposity hormone, leptin. The present study examined the effect of corticotropin-releasing hormone (CRH) on the rewarding effec...
