Do people with fast metabolism have shorter lifespans

There is no direct correlation between fast metabolism and lifespan. The speed of metabolism is influenced by various factors such as genetic factors, exercise habits, dietary structure, hormone levels, and underlying diseases.

Metabolic rate reflects the efficiency of energy expenditure in the body. Fast metabolism is usually manifested by rapid conversion of calories after eating, slightly higher body temperature, or more energy consumption from daily activities. Some studies suggest that a high basal metabolic rate may be accompanied by an increase in free radical production, but clinical data shows that differences in metabolic rate among healthy individuals have limited impact on lifespan. Long term observation has found that although regular exercise groups have higher daily metabolic rates, their average lifespan is actually better than that of sedentary groups, indicating that metabolic rate is not the core factor determining lifespan. In extreme cases, excessive metabolism caused by pathological conditions such as hyperthyroidism may affect health. This type of disease can accelerate heart rate and induce osteoporosis, but metabolic abnormalities can be corrected by controlling thyroid hormone levels with medication. Similarly, slow metabolism caused by severe malnutrition or chronic wasting diseases can also shorten life expectancy. These conditions all belong to pathological metabolic abnormalities and cannot be equated with natural metabolic differences in the general population. The key to maintaining metabolic balance lies in scientifically managing lifestyle. It is recommended to consume sufficient amounts of high-quality protein and complex carbohydrates daily to avoid extreme dieting or overeating; Engage in moderate aerobic exercise and strength training every week to avoid low metabolic rate and excessive consumption; Regular physical examinations focus on thyroid function and bone density indicators. Health and longevity depend more on maintaining overall quality of life, rather than solely pursuing metabolic rate.
