Some common factors which change the metabolism
The most common question I get asked is how to increase the metabolism. I believe many dieters understand that a faster metabolism will speed up weight loss, but they tend to want a faster rate with little or no effort. The most important way to speed up a metabolic rate is regular exercise, however, there are many other ways to influence the pace of human metabolism. Although I must state I do not necessarily recommend some in the list below.
AGE:
Age affects the metabolism for both men and women. After 30 years of age there is usually a gradual decline in lean body weight and an increase in fat weight although this is mainly due to hormonal changes. This will lead to a lowering of the metabolism.
A decline in our metabolic rate can also be attributed to a gradual change in lifestyle which is one thing we can control. It is interesting to note that regular exercise in adulthood will slow the rate at which lean weight is lost and help keep an optimum metabolism.
BODY SIZE:
Size of the body has a major influence on metabolism. A bigger body means more cells to maintain and this requires energy therefore larger people have a higher metabolism. If muscles and build ( body composition ) are naturally large then this will increase metabolism even further.
The extra weight also helps increase metabolism, each movement requires more recruitment of muscle cells to move the mass even if the extra weight is stored fat it still takes more effort to move.
BODY COMPOSITION:
Body composition is another important factor which determines rate of metabolism. Body composition is the difference between total lean weight compared to fat weight. A higher percentage of lean body weight results in a higher metabolism compared to individuals of the same weight will a lower percentage, think of a body builder against a Sumo wrestler!
SEX:
Men naturally have a higher percentage of lean muscle and research suggests this is mainly due to male sex hormones leading to a difference in body size and composition. Therefore men have a higher metabolism than women however most female sportswomen will increase metabolism through years of training.
DIET:
Every time we eat it takes a small amount of energy to digest and absorb all the nutrients present in food (thermogenesis) so eating more frequently can help burn more calories and increase metabolism albeit slightly.
Research shows that after a meal the process of thermogenesis is greater when protein is ingested with the meal rather than just carbohydrate and fat.
PSYCHOLOGICAL STATE:
Stress and anxiety can cause a rapid increase in energy expenditure. When a person is said to be "on edge" or nervous they are in a state of high alert, different chemicals circulate the blood vessels and communicate to cells to break down energy stores ready to provide a greater supply of energy if needed.
DRUGS:
There are many pharmaceutical drugs that can influence the metabolic rate but the more common ones are nicotine and caffeine although the effects are very slight.
