The objective of this work was to study the effect of early weaning on circadian rhythm and the behavioral satiety sequence in adult rats. Male Wistar rat pups were weaned for separation from the mother at 15 (D15), 21 (D21) and 30 (D30) days old. Body weight and food intake was measured every 30 days until pups were 150 days old. At 90 days of age, the circadian rhythm of food intake was evalu...

Several studies have shown that isocaloric diets have different effects on satiety. The aim of the present study was to compare the effect of lunches with different glycemic indexes (GI) in type 2 diabetics. Ten men and women with type 2 diabetes participated in the study. Subjects were given two experimental lunches with glycemic indexes of 43 and 88. Visual analogue rating scales were complet...

Feeding to satiety decreases the acceptability of the taste of food. In order to determine whether the responsiveness of gustatory neurons in the nucleus tractus solitarius (NTS) is influenced by hunger, neural activity in the NTS was analyzed while monkeys were fed to satiety. Gustatory neural activity to glucose, fruit juice, NaCl, HCl and quinine HCl was measured before, while and after the ...

AIMS In humans, impaired gastric accommodation is associated with early satiety and weight loss. In animals, accommodation involves activation of gastric nitrergic neurones. Our aim was to study involvement of nitric oxide in gastric accommodation and in meal induced satiety in humans. METHODS The effect of N(G)-monomethyl-L-arginine (L-NMMA) 4 mg/kg/h and 8 mg/kg/h on gastric compliance, on ...

The impact of sleep restriction on the endogenous circadian rhythms of hunger and satiety were examined in 28 healthy young men. Participants were scheduled to 2 × 24-h days of baseline followed by 8 × 28-h days of forced desynchrony during which sleep was either moderately restricted (equivalent to 6 h in bed/24 h; n = 14) or severely restricted (equivalent to 4 h in bed/24 h; n = 14). Self-re...

Food texture seems to offer a promising strategy for the control of expected satiety, satiation and daily caloric intake. The aim this study was examine effect food texture, more specifically different levels viscosity, on perceived satiety through an online survey where viscosity protein-based beverages were visually using newly developed video-based demonstration. Whey protein prepared with v...

Although the effects of dietary fat and carbohydrate on satiety are well documented, little is known about the impact of these macronutrients on food hedonics. We examined the effects of ad libitum and isoenergetic meals varying in fat and carbohydrate on satiety, energy intake and food hedonics. In all, sixty-five overweight and obese individuals (BMI=30·9 (sd 3·8) kg/m2) completed two separat...

The role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of chlorpheniramine as histamine H1-receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male Ross broiler chicks reared in groups of four weeks, 16 samples (control and test) were then in...

BACKGROUND People who eat more fiber often have a lower body weight than people who eat less fiber. The mechanism for this relationship has been explained, in part, by increased satiety, which may occur as a result of changes in appetite-suppressing gut hormone levels, and decreases in food intake at subsequent meals. OBJECTIVE We hypothesized that increasing doses of mixed fiber, consumed in...

CD36 is a ubiquitous membrane glycoprotein that binds long-chain fatty acids. The presence of a functional CD36 is required for the induction of satiety by a lipid load and its role as a lipid receptor driving cellular signal has recently been demonstrated. Our project aimed to further explore the role of intestinal CD36 in the regulation of food intake. Duodenal infusions of vehicle or sulfo-N...
