Energy balance and reproduction.
The physiological mechanisms that control energy balance are reciprocally linked to those that control reproduction, and together, these mechanisms optimize reproductive success under fluctuating metabolic conditions. Thus, it is difficult to understand the physiology of energy balance without understanding its link to reproductive success. The metabolic sensory stimuli, hormonal mediators and ...
متن کاملEnergy balance and cancers.
Energy balance results from the exact equilibrium between caloric intake and caloric expenditure. A caloric intake larger than caloric expenditure results in overweight, even obesity, but other determinants, like hormonal dysfunction and/or genetic traits may play a part in obesity syndrome. Obesity, and even overweight, have been recognized as risk factors for the development of cancers. Human...
متن کاملReflexions on energy balance.
Calorimetry is the basis of the science of nutrition, a statement I iirst saw as the title of a paper by the chief of the department of medicine at the Mayo Foundation (Wilder, 1959). Our science began when Lavoisier put a guinea pig into a calorimeter, measured the amount of ice melted and showed that this was quantitatively related to the amount of fixed air or carbon dioxide given off by the...
متن کاملEnergy in the Balance
The peroxisome proliferator-activated receptors (PPARs) and the retinoid X receptors (RXRs) are ligand-activated transcription factors that coordinately regulate gene expression. This PPAR-RXR transcriptional complex plays a critical role in energy balance, including triglyceride metabolism, fatty acid handling and storage, and glucose homeostasis: processes whose dysregulation characterize obe...
متن کاملEnergy balance in obesity
The current epidemic of human obesity implies that whilst energy balance appears to be regulated, the extent of this regulatory process is being overwhelmed in large numbers of the population by environmental changes. Clearly, the shift towards positive energy balance reflects both alterations in energy intake and decreases in physical activity. Increased energy intake and, in particular, the r...
