The process of heat production in warm-blooded animals.

“Integral to the cold shock response is the release of norepinephrine, a hormone and neurotransmitter produced in the adrenal glands and some brain regions. Norepinephrine increases heart rate, activates thermogenesis (heat production), constricts blood vessels, and modulates immune function.”

“Dr. Rhonda Patrick speaks with Ray Cronise, a former NASA material scientist and co-founder of zero gravity, a company that offers weightless parabolic flights to consumers and researchers.”

“The indirect calorimetry tests revealed that the participants' diet-induced thermogenesis after breakfast was generally 2.5 times higher than after dinner. The participants' glucose levels were, on average, lower after breakfast than after dinner.”

“Cold-induced thermogenesis involves uncoupling of the mitochondrial electron transport chain, reducing the efficiency of ATP synthesis. This less efficient mode of energy production consumes more calories than normal ATP production and gives off heat as a byproduct.”

“> The new study shows that deleting the BDNF gene also impairs thermogenesis -- the ability of cells to burn fat to produce heat. The study further reveals two distinct types of BDNF neurons -- those that control appetite or satiety and those that control thermogenesis.”

“Adding a sugar-sweetened beverage to a protein-rich meal decreased fat use and diet-induced thermogenesis by more than 40% in people. The study involved participants that spent 24 hours in a metabolic chamber on two separate occasions.”

“For example, the inflammatory response that is triggered after a meal contributes to a less hospitable environment for foodborne pathogens. Furthermore, diet-induced thermogenesis, a rise in body temperature that occurs after eating, may also serve an antibiotic role.”

“Cryotherapy promotes the development of a healthy immune cell population, including cytotoxic T lymphocytes, which play key roles in protecting the body from cancer. Cryotherapy and metabolism The metabolic responses to cryotherapy serve one purpose: to warm the body through a process known as thermogenesis.”

“Repeated, intensive cold exposure can also recruit brown adipose tissue and increase cold-induced thermogenesis. In six men, two hours of daily cooling for four weeks increased active brown-fat volume by 45 percent and more than doubled cold-induced brown-fat oxidative metabolism.”
