What are the two relevant types of body fat?
Beforewe start, it is important to make clear that there are two types offats within a human body. And those would be essential fats andstorage fats.
Essentialfats are critical components of a normal metabolism and a number ofstandard bodily functions. They take up to two to five percent inmen, and ten to thirteen percent in women. This is because a woman'sbody needs more fats in order to perform certain hormonal activities,as well as childbirth.
Essentialfats are stored in the lungs, liver, kidneys, intestines, bonemarrow, muscles, spleen as well as in the CNS.
Dissimilarly,storage fats, are accumulated in the loose connective tissue. Theyrepresent stored energy which may be called upon and used up. Anotherfunction of this tissue is to provide additional protection for otherinternal organs and such.
Storage fats take up about 15% in women and 12% in men.
So what is then the ideal body fatpercentage?
Well,this may vary from person to person. There is a number of factorswhich must be calculated into the equation before coming up with afirm answer. These factors would include: body type, age, sex, hereditary, as well as lifestyle and eating habits.
Ideally,the preferable amount for women is 12% and 5% for men. Women with apercentage lower than 10% and men with a percentage lower than 3% canbe considered unhealthy because of their lack of fat.
Infact, the total body fat percentage of fat is somewhat above thepercentage of the essential body fats. This is because the bodyrequires a source of energy which it may draw upon if needed. Andthis is also why the recommended body fat for a person is alsodetermined by his/her field of work.
Soaccordingly, the American Council of Exercise has created fourrelevant categories: athletes, fit, acceptable and obese.
How would someone measure his or herbody fat percentage?
Thegoal of measuring body fat is to help the person trying to regulatehis/her own, determine whether, according to all of the relevantfactors (age, sex, body type, and so forth) that are plugged into theequation, needs to gain, maintain or lose some.
Whilstlosing body weight, it is very important to determine whether thelost weight comes from the lean body mass or, in fact, the fat mass.
Additionally,BMI is used to determine possible health risks involving weight loss,or to the contrary, suffering from excessive body fat. This methodmainly uses a person's height and weight as the variables which areplugged into the equation, and does not involve measuring body fatpercentage.
