The Role of Brown Fat and Circadian Rhythms (gethealthspan.com)
Circadian rhythms regulate numerous physiological processes, including metabolism, and their disruption is increasingly linked to obesity, insulin resistance, and metabolic disorders. Concurrently, brown adipose tissue (BAT) has emerged as a key player in metabolic health, capable of burning calories through thermogenesis and significantly influencing glucose and lipid metabolism. Recent evidence indicates that BAT activity is strongly influenced by circadian timing, exhibiting diurnal fluctuations that peak in the morning.

Gut microbiota functions:metabolism of nutrients and other food components(2017) (nlm.nih.gov)
The diverse microbial community that inhabits the human gut has an extensive metabolic repertoire that is distinct from, but complements the activity of mammalian enzymes in the liver and gut mucosa and includes functions essential for host digestion.

Oligodendroglial fatty acid metabolism as a CNS energy reserve (nature.com)
Brain function requires a constant supply of glucose. However, the brain has no known energy stores, except for glycogen granules in astrocytes. In the present study, we report that continuous oligodendroglial lipid metabolism provides an energy reserve in white matter tracts.

Obesity is driven by a build-up of molecular mesh around hunger neurons (nature.com)
The accumulation of a network of proteins and sugars called the extracellular matrix stops insulin from reaching hunger-regulating neurons, disrupting normal food intake and metabolism, and contributing to obesity.

Metabolism – How to reduce half-life of caffeine? (stackexchange.com)
Caffeine has a typical half-life of 5–6 hours, but some of us take much longer to metabolize it (1 cup of coffee at breakfast can leave me sleepless that night).
