Acceptable Macronutrient Distribution Ranges (AMDR), are a range of intake specified as a percentage of total energy intake. Used for sources of energy, such as fats ...
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [ 2 ] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
Android fat distribution describes the distribution of human adipose tissue mainly around the trunk and upper body, in areas such as the abdomen, chest, shoulder and nape of the neck. [1] This pattern may lead to an "triangle"-shaped body or central obesity , and is more common in males than in females.
Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [ 1 ] [ 2 ] It also contains the stromal vascular fraction ( SVF ) of cells including preadipocytes , fibroblasts , vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages .
In 2006 the typical American diet was about 2,200 kilocalories (9,200 kJ) per day, with 50% of calories from carbohydrates, 15% protein, and 35% fat. [7] These macronutrient intakes fall within the Acceptable Macronutrient Distribution Ranges (AMDR) for adults identified by the Food and Nutrition Board of the United States Institute of Medicine ...
It is an important electrolyte in the form of phosphate. [72] Food sources include cheese, egg yolk, milk, meat, fish, poultry, whole-grain cereals, and many others. [69] Potassium, an electrolyte (heart and nerve function). With sodium, potassium is involved in maintaining normal water balance, osmotic equilibrium, and acid-base balance.
A typical fat cell is 0.1 mm in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
The main fuel stored in the bodies of animals is fat. A young adult human's fat stores average between about 15–20 kg (33–44 lb), but varies greatly depending on age, sex, and individual disposition. [10]
