The myth that muscle is heavier than fat likely stems from a difference that does exist between fat vs muscle: density. Muscle is denser than fat, which means that if you have one pound of each ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

Experts explain the relation of fat and muscle on weight, how body composition effects overall health, and tips for how to gain muscle and lose fat.
But BMI tends to overestimate body fat in people with a lot of muscle and it doesn’t show how much abdominal fat you have, which is a risk factor for health issues like cardiovascular disease.
Muscle is a soft tissue, one of the four basic types of animal tissue. Muscle tissue gives skeletal muscles the ability to contract. Muscle is formed during embryonic development, in a process known as myogenesis. Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement.
It is now known that brown fat is related not to white fat, but to skeletal muscle. [ 22 ] [ 23 ] [ 24 ] Studies using positron emission tomography scanning of adult humans have shown that brown adipose tissue is still present in most adults in the upper chest and neck (especially paravertebrally).
Your weight will remain 180 pounds, but you’ll have a lower body fat percentage and should look noticeably more muscular, especially compared to if you just gained five pounds of muscle or lost ...
It is a common belief that targeted exercise reduces fat in specific parts of the body —for example, that exercising muscles around the belly reduces fat in the belly. This, however, is now proven to be a misconception; these exercises may change body shape by improving muscle tone but any fat reduction is not specific to the locale. Spot ...
