Adipose tissue, the fat under your skin, is irrigated by blood vessels and any fat stored there is irrigated and used as a building block for tissues and hormones, and also for energy.
Visceral fat only happens because you’ve overloaded your adipose tissue storage and because of an inflammation driven blood profile it ends up “sticking” around your internal organs where it’s decaying releasing inflammatory cytokines like interleukin 6, and other nasty stuff. This in turn causes further inflammation.
Who gets this visceral fat? Anyone eating sugars. Bread, pasta, rice, potatoes, alcohol, fizzy drinks are the highway to this hell. Calories in vs calories out is Coca Cola propaganda along with many rampant nutrition misconceptions. Rosalyn Yallow won the 1977 Nobel Prize in Physiology or Medicine for development of the radioimmunoassay technique showing insulin is forces our metabolism into fat storage. Any sugar consumption will raise our insulin levels. Eating sugars at every meal, something we weren’t doing 200 years ago, results in the obesity epidemic that “nobody seems to know where it comes from”.
Someone won a Nobel Prize for finding this, yet it was swept under the rug and most of the developed world ended up with a food pyramid recommending more grains and vegetable oils, the sure path to cancer, stroke, and heart disease that quickly followed.
