Total daily energy expenditure, or TDEE, is just jargon for what most of us know as metabolism. In simpler terms, it’s about understanding how your body burns energy throughout the day.
Losing or gaining weight affects the energy expenditure. Reduced energy expenditure after weight loss can be a major challenge for people seeking to avoid weight regain after weight loss. [4] It is controversial whether losing weight causes a decrease in energy expenditure greater than expected by the loss of adipose tissue and fat-free mass ...
Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.

Metabolic rift is a theory of ecological crisis tendencies under the capitalist mode of production that sociologist John Bellamy Foster ascribes to Karl Marx.Quoting Marx, Foster defines this as the "irreparable rift in the interdependent process of social metabolism".
Energy usage in transportation and residential sectors (about half of U.S. energy consumption) is largely controlled by individual domestic consumers. Commercial and industrial energy expenditures are determined by businesses entities and other facility managers. National energy policy has a significant effect on energy usage across all four ...
"Sustainability [is] the long-term viability of a community, set of social institutions, or societal practice. In general, sustainability is understood as a form of intergenerational ethics in which the environmental and economic actions taken by present persons do not diminish the opportunities of future persons to enjoy similar levels of ...
The deployment of energy efficiency technologies is highly restricted by factors such as geography, infrastructure and human resources. Behavioral barriers are problems that characterize the end-user's decision-marking relating to energy consumption. Four examples are discussed below. Attitudes toward energy efficiency.
