The Physiological Regulation of Body Fat Mass

Gastroenterology Clinics of North America, 2023
Disturbances inbody weight and adiposity in both humans and animals are met by compensatory adjustments in energy intake and energy expenditure, suggesting that body weight or fat is regulated. From a clinical viewpoint, this is likely to contribute to the difficulty that many people with obesity have in maintaining weight loss.

A Novel Mechanism of Body Mass Regulation

Journal of Experimental Biology, 2001
ABSTRACT While significant attention has been devoted to the identification of hormonal factors that control body mass, little attention has been paid to the role of mechanical loading on animal mass. Here, we provide evidence that intraperitoneal implantation of metabolically inert mass results in a compensatory reduction in tissue mass.

Regulation of Metabolism and Body Fat Mass by Leptin

Annual Review of Nutrition, 2000
The relative stability of body weight over the long term and under a variety of environmental conditions that alter short-term energy intake and expenditure provides strong evidence for the regulation of body energy content. The lipostatic theory of energy balance regulation proposed 40 years ago that circulating factors, generated in proportion to ...

Regulation of body mass in rats exposed to chronic acceleration

American Journal of Physiology-Legacy Content, 1975
Female rats approximately 6 mo old were chronically centrifuged for up to 30 days at 2.76 G or 3.18 G and sacrificed at intervals for body-composition study. Both fat and the fat-free body mass (FFBM) were reduced during the 1st wk of centrifugation, with the fat showing considerably more variation both within and between groups.

Effects of weather on daily body mass regulation in wintering dunlin

Journal of Experimental Biology, 2002
SUMMARYWe investigated the influence of changes in weather associated with winter storms on mass balance, activity and food consumption in captive dunlin (Calidris alpina) held in outdoor aviaries, and compared the aviary results with weather-related body mass differences in free-living dunlin collected at Bolinas Lagoon, California.

Strategic diel regulation of body mass in European robins

Animal Behaviour, 2000
Stochastic dynamic programming (SDP) is a computational technique that has been used to model daily routines of foraging in small birds. A diurnal bird must build up its fat reserves towards dusk in order to avoid starvation during the night, when it cannot feed. However, as well as the benefits of avoiding starvation, storing fat imposes costs such as

Seasonal thermogenesis and body mass regulation in plateau pikas (Ochotona curzoniae)

Oecologia, 2006
Changes in photoperiod, ambient temperature and food availability trigger seasonal acclimatization in physiology and behavior of many animals. In the present study, seasonal adjustments in body mass and in several physiological, hormonal, and biochemical markers were examined in wild-captured plateau pikas (Ochotona curzoniae) from the Qinghai-Tibetan ...

Regulation of body mass and management of childhood overweight

Pediatric Blood & Cancer, 2005
AbstractObesity has become an increasingly important public health problem. Recent evidence suggests that obesity has become a close second to tobacco use as a preventable cause of death in the United States. During the past decade an increase in the prevalence of type 2 diabetes in adolescents has been observed.

Towards an Understanding of Physiological Body Mass Regulation: Seasonal Animal Models

Nutritional Neuroscience, 2000
This review is based around a number of interlinked hypotheses that can be summarised as follows: (i) mammalian body mass is regulated, (ii) the mechanisms that effect this regulation are common to all mammalian species, including humans, (iii) the neurochemical substrates involved in long term body mass regulation and in determining the level of body ...
