Your metabolism is influenced by gender, age, amount of muscle you have compared to body fat and the amount of exercise you do on a regular basis. Male’s rates are higher than females because of testosterone.
Infants and growing children or teenagers have higher metabolic rates than adults because of growth hormone. Research into the use of HGH (human growth hormone) doesn’t increase metabolic rate nor is it a fountain of youth. HGH has some negative side effects for fully grown adults and is only prescribed for children who are not growing at a normal rate.
As you age, men are fairly consistent until about age 70 when testosterone levels drop off. Women’s metabolic rates increase during pregnancy and are even higher when breastfeeding, but drop when women go through menopause. Exercise increases metabolic rate for up to 15 hours after exercise. So get up off the couch, turn off the TV, and do an exercise you like for at least 30 minutes, 5 times per week with an intensity to break a sweat.
