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 .
Thermogenesis is the process of heat production in organisms.It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily (Sauromatum venosum), and the giant water lilies of the genus Victoria.
BMP7 not only stimulates brown adipogenesis, [20] [21] it also stimulates the "browning" of brite or beige adipocytes, turning them from a white-like phenotype into a brown-like phenotype (with induction of UCP1 and able to perform non-shivering thermogenesis, which allows to disperse energy as heat). [22]
However, brown adipose tissue is highly specialized for this non-shivering thermogenesis. First, each cell has a higher number of mitochondria compared to more typical cells. Second, these mitochondria have a higher-than-normal concentration of thermogenin in the inner membrane.

The UCP1, or thermogenin, gene likely arose in an ancestor of modern vertebrates, but did not initially allow for our vertebrate ancestor to use non-shivering thermogenesis for warmth. It wasn't until heat generation was adaptively selected for in placental mammal descendants of this common ancestor that UCP1 evolved its current function in ...
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 ...
Since plateau pikas live in such extremely cold environments and are a non-hibernating species, they have acquired physiological adaptations to better assist with their survival. These adaptations include their high resting metabolic rate and non- shivering thermogenesis along with the production of leptin which is a thermogenesis regulatory ...
