Calculate The Age Of Your Body.

male-agingEach of us has a chronological age that we count in days, weeks, months and birthdays. And then we have a biological age which is determined by the health of our bodies. This biological age is a better predictor of functional capacity at a later age than, for example, the number of times your body has circled the sun.

Researchers at the Norwegian University of Science and Technology have put together a very basic calculator to give some insight into each of our biological ages. It asks for your sex, exercise commitments, chronological age, waistline and resting heart rate. Then, you get your answer. According to the calculator, for example, my body is that of a teenager.

Of course, this calculator is just a very rough estimate. It doesn’t take other risk factors into account – like smoking, drug use, disease, etc. But it can still provide some good insight.

So go ahead! Calculate your biological age.

And then, in the comments below, share your chronological age and biological age. Were you surprised by the difference?

How Many Calories Should I Be Eating? [Harris Benedict Calculator]

If you’ve looked at a nutrition label in the United States, you’ll notice that it says “based on a 2,000 calorie diet.” Does that mean that everyone should be eating 2,000 calories – from Michael Phelps to your grandmother in her nursing home? Of course not.

The Harris Benedict Equation is a formula that will give you a better idea of your ideal caloric intake. It requires four steps.

  1. Calculate your Basal Metabolic Rate (BMR) using one of the equations below:
    Men (Imperial Units/United States): BMR = 66 + ( 6.23 x weight in pounds ) + (12.7 x height in inches ) – ( 6.76 x age in years ) = ________
    Men (Metric Units): BMR = 66 + ( 13.7 x weight in kg ) + ( 5 x height in cm ) – ( 6.76 x age in years ) = ________
    Women (Imperial Units/United States): BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age in years ) = ________
    Women (Metric Units): BMR = 655 + ( 9.6 x weight in kg ) + ( 1.8 x height in cm ) – ( 4.7 x age in years ) = ________
  2. Determine your current fitness level:
    Sedentary: little or no exercise
    Lightly Active: light exercise/sports 1-3 days/week
    Moderately Active: moderate exercise/sports 3-5 days/week
    Very Active: hard exercise/sports 6-7 days a week
    Extra Active: very hard exercise/sports & physical job or 2x training
  3. Calculate the number of calories that you require in a day based on BMR and fitness level:
    Sedentary:  Daily calories needed= BMR x 1.2    = __________
    Lightly Active: Daily calories needed= BMR x 1.375  = __________
    Moderately Active:  Daily calories needed= BMR x 1.55  = __________
    Very Active: Daily calories needed= BMR x 1.725    = __________
    Extra Active:  Daily calories needed= BMR x 1.9  = __________
  4. Compare. Use a journal to track your caloric intake against your actual weight – this is really the only way to know for sure!

It’s not as complicated as it sounds. For example, at 155lbs, 5’9” and leading a very active lifestyle, I should be consuming 2,840 calories a day according to the equation. Or, just less than a full 14″ cheese pizza from Pizza Hut. 😛

Why does it matter? Weight loss can only be achieved through a calorie deficit – that is, taking in less calories than are used. Using this equation, you can get a rough idea for how many calories that should be.

And if you’re not trying to lose weight, it’s still a good idea to get a general sense of how many calories you should be eating in order to avoid weight gain.

So, whip out your calculate and crunch the numbers. How many calories should you be eating? Let me know in the comments below!
