Kehonrasvan

Kehonrasvan is the term used to describe body fat, a type of adipose tissue that stores energy in the form of triglycerides. It also serves as an insulating layer, cushions organs, and functions as an endocrine organ by secreting adipokines that influence metabolism, appetite, and inflammation.

There are different forms of adipose tissue. White adipose tissue stores excess energy and provides insulation, while brown adipose tissue burns fat to generate heat through thermogenesis, a feature more prominent in infants and in some adults under certain conditions. Beige or brite adipose tissue can develop brown-like properties in response to external stimuli. Adipose tissue is distributed in various depots, with subcutaneous fat beneath the skin being the largest, and visceral fat surrounding internal organs. Ectopic fat can accumulate in organs such as the liver or heart.

Kehonrasvan is involved in several physiological processes beyond energy storage. It releases hormones and signaling molecules, influencing glucose metabolism, lipid handling, immune responses, and appetite regulation. The amount and distribution of body fat affect health risks: increased visceral adiposity is associated with higher risks of metabolic syndrome, type 2 diabetes, cardiovascular disease, and inflammation. Body fat can be assessed directly or indirectly via methods such as DEXA scans, MRI, or CT; skinfold measurements and bioelectrical impedance offer estimations. Body fat percentage and distribution often provide more insight into health status than body mass index alone.

Regulation of kehonrasvan is dynamic, responding to energy balance, hormones (including insulin and cortisol), and lifestyle factors. Aging, sex, and genetics influence its amount and distribution, with typical patterns showing more visceral fat in men and a shift toward subcutaneous fat in some women after menopause. Exercise and nutrition remain key modifiers of body fat stores.
