Muscle vs. Fat
Body fat and muscle are two completely different tissues. Have different structures and functions, they react to training in different ways and, in short, one does not have the ability to become the other.
Composition and Functions
Adipose tissue is a specialized connective tissue in which conjunctival cells called predominantly adipocytes.
Adipocytes store energy in the form of triglycerides. Due to the low density of these molecules and their high caloric value, fat is very efficient in the function of energy storage.
It also serves to insulate the body and protect organs and to produce hormones important in regulating appetite.
Muscle tissue is a tissue that is formed by the muscle fibers or myocytes.
It comprises approximately 40% and 45% of the mass of humans and is specialized in the contraction, allowing living creatures to move. Are also responsible for stabilizing the position, it serves as a source of energy and heat.
Loss / Increase
The loss or gain of body fat is entirely related to the calories and the amount we have is directly influenced by the number of calories consumed with calories expended. Calories consumed obviously come from the food we eat.
It is important to recognize that when we consume any food in excess, whether carbohydrate, protein or fat, it turns into body fat. You can not lose fat in a localized area. Fat loss occurs throughout the entire body at once.
Your body stores fat for fuel and when a weight loss program your body burns fat from all areas of your body so that part is not depleted starts. That’s because fat also acts as an insulator body and your body does not want to leave an area without thermal insulation.
Although the profit or loss of muscle mass is also closely related to intake and caloric expenditure, changes in muscle are also influenced by the normal stresses that are placed on each one individually.
These stresses can be through work-related activities, daily tasks, activity aerobic or strength training. The key factor is that the muscle will only react if the stress placed on it exceeds the daily stress to which he is accustomed. Unlike fat, each muscle can increase specifically so you can choose the specific area you would like to improve.
Sure you’ve heard that fat weighs less than muscle, but technically it is not correct. A kilo is a kilo if it is a kilo of fat, muscle kilo or a kilo of feathers. It is more correct to say that fat is less dense than muscle, which means that:
A kilo of fat takes up more space on the body than a kilo of muscle.
Two people can have the same height and weight, but the person who has a higher percentage of body fat will use a size larger clothes.
Since muscle is heavier than fat, muscle weighs more than fat if two portions of the same size are compared. On average, the density of the fat is 0.9 g / ml. The muscle density is 1.1 g / ml . 1 liter of muscle weighs 1.06 kg, or 2.3 lbs., While that 1 liter of fat weighs 0.9 kg, or 1.98 lbs.
Muscles are metabolically more active than fat. A pound of muscle (453g) burns about 6.5 calories s per hour. Muscle burns 5.5 times more calories than fat. A pound of fat burns about 1.2 calories pound per hour.
