Non-exercise activity thermogenesis (NEAT), also known as non-exercise physical activity (NEPA), [1] is energy expenditure during activities that are not part of a structured exercise program. NEAT includes physical activity at the workplace, hobbies, standing instead of sitting, walking around, climbing stairs, doing chores, and fidgeting .
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 during weight loss. [5] This excess reduction is termed adaptive thermogenesis and it is estimated that it might compose 50 to 100 kcal/day in people actively losing weight. Some studies have ...
The low demands of thermogenesis mean that free fatty acids draw, for the most part, on lipolysis as the method of energy production. A comprehensive list of human and mouse genes regulating cold-induced thermogenesis (CIT) in living animals or tissue samples has been assembled [15] and is available in CITGeneDB. [16]
Metabolism comprises the processes that the body needs to function. [2] Basal metabolic rate is the amount of energy per unit of time that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles ...
Specific dynamic action (SDA), also known as thermic effect of food (TEF) or dietary induced thermogenesis (DIT), is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage. [1]
Non-shivering thermogenesis is a regulated process in which the proton gradient generated by electron transport in mitochondria is used to produce heat instead of ATP in brown adipose tissue. [3] Animals that hibernate include bats , ground squirrels and other rodents, mouse lemurs, the European hedgehog and other insectivores, monotremes and ...

Thermogenic means tending to produce heat, and the term is commonly applied to drugs which increase heat through metabolic stimulation, [1] or to microorganisms which create heat within organic waste.
