“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.”

“Activating brown fat upon cold exposure may improve glucose and insulin sensitivity, increase fat utilization, and protect against diet-induced obesity. Studies in animals and humans have indicated that brown fat can improve glucose and insulin sensitivity, increase fat oxidation, and protect against diet-induced obesity.”

“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.”

“When the mice were given a 400 mg/kg/bw nicotinamide riboside supplement, their mitochondrial biogenesis (the process by which new mitochondria are made inside cells) increased in both muscle and brown adipose tissue.”

“Brown fat activity contributes to overall energy expenditure and the regulation of body fat. The authors of the study conducted a two-part investigation. In the first part, 21 healthy men (20 to 50 years old) underwent positron emission tomography (PET) scans to detect the presence of brown fat.”

“Some nutrients and bioactive compounds, such as curcumin, capsaicin, resveratrol, and omega-3 fatty acids, may increase brown fat production, too. Link to full study. Listen to this podcast in which Dr. Rhonda Patrick describes how cold exposure induces brown fat production.”

“Cold exposure increases brown fat activity in humans, possibly benefitting whole-body glucose utilization and insulin sensitivity. Learn more about the effects of cold exposure in our overview article. Read study abstract and preview.”

“The assay can detect within-person changes in autophagic flux, but it remains a research method and is not a validated clinical biomarker of biological aging. Deregulated nutrient sensing The body employs many sensing pathways that detect intra- and extracellular fat, amino acid, and sugar concentrations.”

“FTA: > Dillin and colleagues found that not only did the brown fat ramp up its activity in the smell-deficient animals, but some of their white fat also became more like brown fat. “They rewire their metabolic programming to burn more calories,” he says. When a mouse can’t smell its food, he speculates, it may “think” that it has eaten more than it really has, prompting it to use more energy.”
