At what age does your metabolism slow down?

    For males the average age range is between twenty eight and thirty five. However for some the metabolism doesn't change all that significantly.

    This is largely a myth - metabolism mostly slows down because people move less as they age.

    There is a small natural decrease in Basal Metabolic Rate (how much your body burns without exercise) but its only about 20 calories per decade.

    For example, if an individual continued to move the same amount throughout their life and maintained the same body composition, their maintenance calories would go from say 2,400 at 40 years old, to 2,380 at 50 years old. 

    By the time they reach 80 their maintenance calories would still be roughly 2,320 - not a big difference

    The first slow down happens at about age 20. That's when people stop growing.  Anyone can tell you how much a thin high school student can eat and how heavy that same person can be just a couple years later if they don't change their calorie consumption.

    From that point, our metabolism slows and the rate at which we break down food decreases by 10 percent each decade after age 20.

    That noted, a slowing metabolism actually has a minimal impact on weight.  The main reason people gain weight as they age has to do with increased consumption of calories and more sedentary lifestyles.

    Everyone's Brain and body takes a real nose dive by 40.

    Mathematicians are done by 40 in most cases. 

    So are 99% of athletes. The body just starts giving in.

    That can vary just based on lifestyle, gender, and other factors that would need to be considered based on each specific person.

    In general, your lifestyle and your choices can slow your metabolism BEFORE your age would ever do it.

    Even if doing everything perfect - just changes that happen as we age can affect metabolism.  Changes in hormone levels and changes in how the body functions in general impacts metabolism.  Before the age of 20 - teens burn calories easier because their body is still growing.  When the body no longer needs to spend calories to grow, the first change in metabolism happens.  Then, as people age, metabolism declines at about 10% per each decade of age.  It is part of the natural aging process.

    I didn't find too much related directly to male health - but male hormones also change as men age and lifestyle habits would have similar issues on men as they do on women.
