From the viewpoint of diet and weight loss, metabolism is the process whereby the body converts food into energy (or uses it for bodily repairs) or stores it as fat for future use. In simple terms, if we have a faster metabolism we burn calories more efficiently and store less fat. If we have a slower metabolism we burn calories less efficiently and therefore store more calories as fat. In very si mple terms, our Metabolic Rate is the rate (and efficiency) with which our body performs these metabolic tasks.

How does Human Metabolism Work? - Resting Metabolic Rate (RMR)
-This is the amount of calories needed to run all essential functions and chemical reactions while in a rested and quiet state. RMR is the largest part of total metabolism and accounts for 65 - 75% of calories burned in a day.
-If lean weight is lost from the body through increased protein metabolism the RMR decreases. This often happens when people go on a strict diet, the body is forced into what's known as a "negative nitrogen balance" which means more protein is lost than what is replaced due to less protein/energy intake . This imbalance causes a gradual loss in lean weight thus lowering the RMR.
-Many dieters limit the amount of lean weight loss with some type of intense exercise in order for muscles to develop a

Basal Metabolic Rate (BMR)
-In order to compare one person's metabolism with another's, scientists have devised a new buzz word - basal metabolic rate (BMR). Your BMR is the rate at which you use u p energy when at rest - e.g. when you are sleeping or just lying in bed. You might call it your tick over speed.
- The more you weigh the higher your BMR will be. The metabolic rate of very fat wom en is 25% higher than that of thin women.
- BMR is much greater in childhood than in adulthood. After the age of about 20, it drops about 2 per cent, per decade.
- People whose bodies contai n a higher proportion of muscle to fat, tend to have a higher BMR than those with lower muscular proportions - all other things being equal.

Effective fat loss cannot occur when the metabolism is low!
-Its a physiological fact that when losing weight we also lose protein from muscle. The faster the weight loss the more protein is used f or energy and/or protein synthesis and a net loss of protein will always decrease the metabolism.
-As protein is lost from cells it gradually lowers the total lean body weight, this affects the bo dy composition and lowers the metabolism. As this occurs it means we gradually require less calories to maintain weight so if the present diet is continued results will eventually stop, its even possi ble to slowly GAIN back weight that was previously lost!

Even if more exercise is undertaken a net loss of protein can occur if calorie intake is low.
-Remember dieters reduce their calorie intake but exercise uses extra carbs so the body must breakdown extra protein to convert into carbohydrates. More carbs are needed because a less fit individual often has an untrained cardiovascular system and cannot supply enough oxygen for cells to burn fat for energy during the exercise. Also if no exercise is performed the body has no need to use extra body fat because so little energy is required when inactive.
-Exercise can increase metabolism but the trick for the unfit person is to perform the correct exercise and not cut calories too much too soon. To lose FAT weight fast the best way is to prepare the body by increasing the metabolism BEFORE c
