Individual Metabolism Rates: why do some people lose weight more quickly than others?

Metabolism depends on several individual traits and factors: age, sex, body composition, existence or absence of certain diseases, practice of physical exercise, nutrition and recent weight loss, among others.

Considering all of these factors, there are individuals with similar weight and age, but who show a difference of up to a thousand kcal / day in their energy metabolism, that is, one is slower while the other is accelerated.

Those who have accelerated metabolism tend to lose weight faster.

What is metabolism?

Energy metabolism is the set of chemical reactions that coordinate the mathematics of calories that occur in the body in order to produce, consume and store energy daily.

From the age of 45, a reduction in metabolism from 3% to 4% per decade can occur as a result of the loss of muscle mass occurring with advancing age.
Body composition is also a key factor in energy expenditure. Half a pound of muscle mass causes the body to consume 40 kcal / day and a half pound of fat, 6 kcal / day. The more muscle mass we have, the more accelerated is our metabolism.

Another factor that can influence metabolism is the indiscriminate use of very restrictive and ‘trendy’ diets, because after such deprivation, the body usually protects itself from severe caloric restriction and weight loss with a reduction in energy expenditure greater than expected loss of fat and muscle mass.
This reduction in metabolism is called adaptive thermogenesis and causes an individual to expend less and less calories.

In addition, the type of diet also influences energy expenditure. High-protein foods increase caloric expenditure through diet-induced thermogenesis. Diets with more carbohydrates cause a lower reduction of thermogenesis induced by the diet, that is, they favor slower metabolism.

The level, time and type of physical activity also influences, logically, metabolism. However, more and more, we note the importance of lifestyle and involuntary or daily physical activity in energy expenditure. More active people, who do daily work activities that require walking or some other type of physical activity on a regular basis, tend to have higher rates of metabolism.

In conclusion, some individuals lose weight faster than others because of differences in their body composition, diets, physical activity, and age. The greater their muscle mass, the more adequate and healthy their diet and the more active the patients are, the greater their chance of losing weight quicker.
