Visceral fat
Visceral fat is different from other body fat. Visceral fat, also called intra-abdominal fat, refers to the fat that surrounds the internal organs. Subcutaneous fat, on the other hand, is body fat that is close to the skin's surface and is considered less dangerous, and easier to lose, than visceral fat.
Studies have shown that those with visceral fat are more susceptible to heart disease, stroke, diabetes and hypertension. Sedentary people, smokers and drinkers have been shown to have more intra-abdominal fat, or visceral fat, than active people who are non-smokers and non-drinkers. Stress may also be a factor in the storage of visceral fat on the body.
Visceral fat is harder to lose than subcutaneous fat because it is more deeply embedded in the body's tissues. Visceral fat is only measured accurately by an imaging machine that can see how much of the abdomen is made up of visceral fat. A person may be within a healthy weight range, but still have too much intra-abdominal fat around the internal organs.
The liver metabolizes visceral fat and releases it into the bloodstream as cholesterol. Harmful, or "bad" cholesterol, which is Low-Density Lipoprotein (LDL), builds up into a plaque that blocks the arteries. Losing weight through proper diet and effective exercise can help reduce visceral fat. How much fat a person eats does matter as studies have shown that those who eat 30% or more of their diets as fat usually have high amounts of visceral fat.
Walking is considered by many health and fitness experts to be a much better way of helping to control visceral fat than by doing exercises such as swimming where gravity keeps the body afloat. Walking at a fairly fast pace for a half an hour six days a week has been shown to help reduce visceral fat, while walking only three days a week has not been shown to have much affect on the reduction of visceral fat. However, doing no exercise at all has shown to increase the amount of visceral fat in the body.

Skeletal muscle
Skeletal muscle is a form of striated muscle tissue existing under control of the somatic nervous system. It is one of three major muscle types, the others being cardiac and smooth muscle. As its name suggests, skeletal muscle is linked to bone by bundles of collagen fibers known as tendons.
Skeletal muscle is made up of individual components known as muscle fibers. These fibers are formed from the fusion of developmental myoblasts. The myofibers are long, cylindrical, multinucleated cells composed of actin and myosin myofibrils repeated as a sarcomere, the basic functional unit of the cell and responsible for skeletal muscle's striated appearance and forming the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers held together by connective tissue.

Body fat percentage
A person's total body fat percentage is the total weight of the person's fat divided by the person's weight. The resulting number reflects both essential fat and storage fat.
Essential fat is that amount of fat necessary for maintenance of life and reproductive functions. The percentage for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Essential fat is 2–5% in men, and 10–13% in women.
Storage fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. The minimum recommended total body fat percentage exceeds the essential fat percentage value reported above. A number of online tools are available for calculating estimated body fat percentage.
Arguably, body fat percentage is the superior gauge of an individual's fitness level, as it is the only body measurement which directly calculates the particular individual's body composition without regard to the individual's height or weight. The widely-used body mass index (BMI), on the other hand, simply makes blanket assumptions as to what every individual of a certain height should ideally weigh, regardless of the body composition which makes up that weight. The BMI gives particularly inaccurate information with regard to individuals with above-average lean muscle mass, classifying such individuals as "overweight" or "obese" despite the fact that their body fat percentage would indicate they are in excellent physical condition.
