The weight of an individual is determined by many different factors, some of which are within the control of the individual while others are beyond control. The height of an individual as well as the density of bones is something that is impossible to change. Other factors that influence the weight of the individual are muscle mass and fat quantity on the body. These are two factors that are within the control of an individual. When food is consumed, it is broken down in the digestive system and passed into the blood stream. Through the blood, food is transported to different parts of the body.
The different parts of the body break down food to generate energy. Energy is required for every single body function and this is produced by the process of metabolism. Food consumption takes place three or four times a day typically. Food is therefore stored temporarily in the muscle tissue and in the liver. This temporarily stored food can be used later in the day for energy production. Food that is unused can be converted into fat. When the diet contains lots of fat, the body tends to store some of this fat for later energy production. These two factors are the main reasons why people suffer from overweight problems. The definition of overweight depends on which type of scale one is using. The most popular scale to define this condition is the body mass index calculation. Using this calculator, one can arrive at a numerical figure for the mass index of an individual based on the height of the individual and his or her weight. The index then classifies the individual as underweight, normal weight or overweight. Both extremes of this classification are dangerous to the long term health of the individual. Underweight and overweight people are more likely to develop medical conditions than people with normal body weight, statistically speaking. The most common overweight causes are diet and exercise regimes. When an individual consumes an unhealthy diet with insufficient healthy food, he or she is setting up for a situation where the body will not function efficiently. Weight gain is a result of consuming too much food, especially food that is not particularly nutritious. A lack of nutrition often causes the individual to seek more food as the body will require nutrition to perform its functions. When an individual is already overweight, he or she is likely to eat heavily in order to sustain the excess body mass. This causes further weight gain. Exercise is required to burn off energy that is produced in the body. This will make it necessary for the body to produce even more energy and this leads to the breakdown of more food. Initially, the body will access nutrition that has recently been consumed and temporarily stored nutrition for energy. When the body runs out of these sources, the process of fat breakdown will take place. This is why one needs to undertake endurance exercises in order to burn fat and lose weight.
