Food Deprivation

SIRT1 is a NAD+-dependent deacetylase implicated in longevity and diverse physiological processes. SIRT1, as a key mediator of beneficial effects of caloric restriction, regulates lipid and glucose metabolism by deacetylating metabolic regulators, as well as histones, in response to nutritional deprivation.

We measured life span and fecundity of three reproductive modes in a clone of the monogonont rotifer Brachionus manjavacas subjected to chronic caloric restriction (CCR) over a range of food concentrations or to intermittent fasting (IF). IF increased life span 50%-70% for all three modes, whereas CCR increased life span of asexual females derived from sexually or asexually produced eggs, but not that of sexual females.

Recent studies in fruit flies have imposed dietary restriction (DR) by diluting yeast and have reported increased lifespan as the yeast-to-sugar ratio decreased. In this study, the effects of DR on the lifespan of Bactrocera dorsalis were investigated using constant-feeding diets with different yeast:sugar ratios and an intermittent-feeding diet in which flies ate every sixth day. Antioxidant enzyme activities and the malondialdehyde concentration were also measured in virgin females under constant-feeding DR protocols to investigate their relationships with lifespan.

The current research examines the effect of self-regulation on the likelihood of committing infidelity. Thirty-two college students in exclusive romantic relationships interacted through a private chat room with an opposite-sex confederate. Prior to this interaction, a food-restriction task depleted half the participants of self-control. As predicted, depleted levels of self-regulation increased the likelihood of infidelity.

The study of the interaction between the "animal hypnosis" and hunger dominant after its multiple creation showed that the first applications of the forced immobilization against the background of hunger dominant optimum elicited the long-lasting hypnotic state of the animal (4-20 minutes). The hunger dominant was retained in hypnotic state of the animal, i.e., the testing stimuli produced summation swallowing and masticatory movements.

Influence of intragastric formula infusion rate on resting thermogenesis was evaluated in 24 healthy subjects. Metabolic rate (M) was measured by indirect calorimetry following an overnight fast. Subgroups then received a continuous intragastric infusion of a formula diet at three levels: submaintenance (mean +/- SEM, 1.02 +/- 0.04 times fasting M, n = 6), maintenance (1.39 +/- 0.01 times fasting M, n = 20), or supramaintenance (2.77 +/- 0.2 times fasting M, n = 14). Formula inflow was started in the evening, and intraprandial M was measured throughout the following day.

Prolonged total food deprivation in non-obese adults is rare, and few studies have documented body composition changes in this setting. In a group of eight hunger strikers who refused alimentation for 43 days, water and energy compartments were estimated, aiming to assess the impact of progressive starvation. Measurements included body mass index (BMI), triceps skinfold (TSF), arm muscle circumference (AMC), and bioimpedance (BIA) determinations of water, fat, lean body mass (LBM), and total resistance. Indirect calorimetry was also performed in one occasion.

OBJECTIVE: To observe the physiological and biochemical effects of intermittent fasting combined with hunger-resistant food on mice, and to evaluate the safety and beneficial effects of this regimen. METHODS: One hundred and forty-four adult ICR mice were divided into 4 groups: standard feed AL group (ad libitum intake of standard feed), hunger-resistant food AL group (ad libitum intake of hunger-resistant food), standard feed IF group (feeding standard feed and fasting on alternate days), and hunger-resistant food IF group (feeding hunger-resistant food and fasting on alternate days).
