In terms of your health, your body fat percentage should fall within a certain range. For men, that means a body fat percentage of less than 21 percent, and for women it's less than 31 percent.
Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat. [5] Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6]
Both are important measures of health, but body fat — and whether you store it around your middle — may be more helpful in determining whether you have a healthy weight or a higher risk for ...
“You need fat for energy,” Korner explains. “Subcutaneous fat is important to protect the bones and internal organs, provide insulation and even produce some beneficial proteins.”
For example, bears hibernate for about 7 months, and during this entire period, the energy is derived from degradation of fat stores. Migrating birds similarly build up large fat reserves before embarking on their intercontinental journeys. [17] The fat stores of young adult humans average between about 10–20 kg, but vary greatly depending on ...
The typically female (or gynecoid) pattern of body fat distribution around the hips, thighs, and buttocks is subcutaneous fat, and therefore poses less of a health risk compared to visceral fat. [37] [38] Like all other fat organs, subcutaneous fat is an active part of the endocrine system, secreting the hormones leptin and resistin. [35]
In 1827, William Prout recognized fat ("oily" alimentary matters), along with protein ("albuminous") and carbohydrate ("saccharine"), as an important nutrient for humans and animals. [ 13 ] [ 14 ] For a century, chemists regarded "fats" as only simple lipids made of fatty acids and glycerol (glycerides), but new forms were described later.
