The appropriate answer is 3. Fats. Fat is a triglyceride molecule. Collectively fats form a type of tissue known as adipose tissue. The primary function of fat is energy storage but when concentrated in adipose tissue it provides thermal insulation and also doubles as a shock absorber for vital organs in the body.
Nucleic acids transmits genetic information and is used in cellular activities such as protein synthesis. Carbohydrates when broken down provides heat but are not involved in insulating the body.
Fat is a quite simple component to measure. Increased or
above normal/ average body fat has been proven to be linked with many health
risks.<span>
<span>Body weight is not always an accurate indication
of body composition. If you were to equate an NFL running back who is 5'
10" and weighs 200 lbs, to a 5'10" 200 lbs. banker, there body
composition would be VERY unalike although there weight is exactly the same. Of
course the football player is healthier, because he is perhaps carrying one
third of the body fat as the banker of the same weight. Maintaining that muscle
mass would also infer healthy habits like nutrition and exercise.</span></span>
