Metabolism is the rate at which your body consumes calories. Someone with a high metabolic rate is able to burn calories more efficiently than someone with a slower metabolic rate. Assuming these two people eat roughly the same amount of calories, the individual with a faster metabolic rate “burns up” more of the calories she eats; the person who has the slower metabolism doesn’t burn all the calories taken in, so the extra calories are “saved” and then converted to fat.
Since many factors can affect your metabolism (e.g. age, overall health), it can actually slow down without you making any lifestyle changes. The good news is that aerobic exercise is an ideal way to increase your metabolism and combat weight gain.
Aging in particular has a noticeable impact on your metabolism, due to changes in hormone balance. That doesn’t mean aging makes weight gain inevitable. A 2001 study by the USDA Agricultural Research Service showed that older people can significantly improve their metabolism and fend of weight gain by participating in strength training (using weights or other resistance) exercise. The reason both exercise and strength training can improve your metabolism? Muscle burns calories more efficiently than fat; the more muscle you have in relation to your body fat, the higher your metabolism will be.
Metabolism is an important part of the weight-loss formula. It’s important to burn as many calories as possible when trying to lose weight, and metabolism plays right into that.
