In terms of location in the human body, there are three types of fat. Intramuscular fat is found interspersed in the skeletal muscle. Subcutaneous fat is found underneath the skin. Visceral fat (VF) is also known as organ fat because it is stored in between the internal organs and the torso, inside the peritoneal cavity. An excess of visceral fat is known as central obesity, abdominal obesity, potbelly and beer belly. VF includes epididymis white adipose tissue and perianal fat. Subcutaneous fat can be easily pinched between the fingers, but VF lies deep inside and can be found in thin people too. It is associated with an apple shaped body. Men have fat stored in the abdomen, while for women fat is stored in thighs and hips. After menopause, as the estrogen production falls, fat is stored in the abdomen. A Point to note is fat cells remain the same throughout the life span. What changes is the size of fat cells.
According to several studies including the MESA study published in Journal of American College of Cardiology (2014), higher VF was associated with cardio metabolic risk and coronary artery calcification, regardless of body mass index (BMI). It is the VF rather than subcutaneous fat that is more strongly associated with incident metabolic syndrome irrespective of age, race, or BMI. Metabolic syndrome is a series of risk factors that occur together as a group, raising risk of coronary heart diseases, stroke and diabetes. The five risk factors include large waistline or abdominal obesity; elevated triglycerides; low levels of high-density lipoprotein cholesterol (HDL-C); high blood pressure ; and elevated fasting glucose.
Most of the fat we consume through our diet, that is, as saturated, polyunsaturated, and monounsaturated fats are all types of triglycerides. They are a major source of our energy at rest and during low-intensity exercise. The digestion of fat is mainly processed in the small intestine. A scheme enters the duodenum, bicarbonate ions are secreted by the pancreas to neutralize the pH of the chyme, lipases and enzymes that break down fat. The gall bladder contraction allows bile to be released from the liver.
Fats, And triglycerides are hydrophobic, and do not dissolve in water. Bile prevents fat molecules to clump together to form one big fat molecule. Bile molecules have a hydrophobic end and a hydrophilic end. The hydrophobic end sticks to each fat molecule. The hydrophilic end protrudes and prevents the molecules from sticking together. The combined structures of fat molecules and bile molecules are called micelles, which are small spherical water-soluble droplets.
As fat Molecules become micelles, lipases break down fat molecules into free fatty acids and, which are easily absorbed through the small intestine. After they pass the intestinal wall, fatty acids and recombine to form triglycerides. The triglycerides Combine with Cholesterol, phospholipids and protein to form a structure called. It has a protein coating which makes it water-soluble, and it easily travels through the lymph vessels and then the bloodstream. These compounds are metabolized and used as a source of energy by the muscle fibers, and the utilized compounds are broken down and stored as free fatty acids in the liver or as body fat. Thus, right habits can help to lose belly fat in men and women.
