“Diet-induced thermogenesis involves an increase in the metabolic rate that occurs after consuming a meal. Cold-induced thermogenesis involves uncoupling electron transport from ATP synthesis and repetitive, non-productive transport of ions across the adipose cell membrane.”

“Every other day fasting primarily alters the gut microbiota composition to promote the generation of acetate and lactate and this increased mitochondrial density in adipose tissue. The higher mitochondrial density in white adipose tissue caused the "browning" of the fat which results in increased energy expenditure through non-shivering thermogenesis.”

“Capsaicin (the active compound in chili peppers) activate a receptor called Transient Receptor Potential (TRP) channels and this has been shown to stimulate cellular mechanisms against obesity, by altering mediators of lipid catabolism and thermogenesis.”

“The delayed rats' brown fat contained higher quantities of various proteins involved in thermogenesis, including fibroblast growth factor 21 (FGF21). FGF21 activates neurons in the brain involved in metabolic regulation.”

“Slower caffeine breakdown keeps circulating levels elevated for longer periods, which may increase energy expenditure through caffeine-induced thermogenesis and fat oxidation. Experimental work suggests caffeine enhances mitochondrial activity, increases sympathetic nervous system signaling, and shifts brown fat tissue toward a more metabolically active state.”

“The color of fat tissue – white, brown, or beige – dictates the role the tissue plays in the body. Whereas white fat is involved in lipid storage and the release of free fatty acids for energy, brown fat is involved primarily in thermogenesis – the production of heat.”

“Non-exercise activity thermogenesis (NEAT): the energy expended during unconscious activities throughout the day. TEF accounts for around 30% of total daily energy expenditure. Physical activity: the energy we expend doing purposeful exercise.”

“Other hormetic responses to cold exposure include increased production of PGC1-alpha, a protein that promotes mitochondrial biogenesis, the production of new, healthy mitochondria, and the activation of brown fat – a phenomenon once thought to occur only in newborns, but now known to occur in adults, especially after cold exposure.”
