Your Body: Some Interesting Facts and Numbers

Okay, so today I’m wearing my exercise science hat, my research lab coat and my coach’s whistle. All at the same time. If you’re already in Olympic condition, feel free to bypass this instalment and swing by tomorrow. 

  • There are 1440 minutes in every day.
  • Despite popular thinking, nobody has any less time (in their day) than anyone else.
  • The most common ‘reason’ given for not exercising is… lack of time.
  • The average Aussie watches around 25 hours of TV each week (the number is similar for many other countries).
  • The average Aussie is (1) overweight and (2) doesn’t want to be.
  • As little as 15 minutes of daily exercise will produce noticeable physiological change within one week.
  • If the average Aussie substituted 20% of their TV time for exercise, they would (1) still be watching 20 hours of TV each week (2) spend 260 hours exercising each year and (3) be in much better shape.
  • More than 80% of current gym members either (1) never actually go to the gym or (2) rarely go.
  • Research shows that most people who start a new weight-loss or fitness program on a Monday fail.
  • Why? Because nobody starts on a Sunday.
  • If you consistently expend 500 more calories than you consume (each day), your real weight loss (that is, fat loss) will be about one pound (just under 0.5kg) per week.
  • Rapid weight loss should not be confused with rapid fat loss. They are not the same.
  • My weight can vary by as much as 2.5 kgs (5.5lbs) in one day. For some people, the number is greater. This is not an indication of fat loss or gain on my part but rather, hydration levels along with stomach and bowel contents (you wanted to know).
  • 1 litre of water weighs 1 kilogram. Therefore, the woman who weighs 60 kgs at 8am and (for some reason) decides to drink a litre of water at 8.01am will show 61 kgs on the scales by 8.02am. Clearly, there is temporary (and instant) weight gain but no fat gain.
  • Most commercial metabolism boosters (fat-burners) increase blood pressure, resting heart rate, core body temperature and risk of heart attack, stroke and death.
  • 100 grams (3.5oz) of peanuts contains 622 calories, while the same weight of strawberries contains a mere 28.
  • It will take a 73kg (160lbs) individual walking at 5kph (3mph) 2 hours and 21 minutes to expend (burn off) those peanut calories. Not worth it, really. ;)
  • If you are overweight, one advantage is that, when you exercise, you will expend more energy (burn more cals) per unit of time than your annoyingly skinny friend doing the exact same workout. :)
  • Severe low carb diets are more likely to lead to temporary stinky breath, lethargy, impaired mental function, constipation, headaches, kidney stress and moodiness than any kind of lasting weight or fat loss.
  • Height-weight charts suggest that I’m currently about 10 kgs (22lbs) overweight; despite having a body-fat percentage of less than ten.
  • Body composition provides a much more accurate indication of current or future health risk than does body weight.
  • Unless you do exactly the same thing every day (I mean exactly), then your nutritional needs (cals, protein, fats, carbs, vitamins, minerals) will vary from day to day.
  • The U.S. spends about 170 million dollars each day on weight-loss programs, products and services. Interestingly, obesity levels are not declining.
  • It will take a 60kg (132lb) woman 1.55 hours of cycling at 20kph (12mph) to ‘burn off’ one Big Mac. Salad anyone?
  • 92% of the Calories in Nutella come from fat and sugar.
  • If you’re still reading this, there’s an 84% chance you’re an over-thinker.
  • I totally made that last stat up.
  • Or did I? ;)

I could go on but that’s probably enough for now. :)

I enjoyed reading this, it was very interesting. One thing makes me curious though – if you are 22 lb overweight for height/weight charts, and you know that eating 500 cals less than you expend per day will give you 1 lb weight loss a week, it would only take 22 weeks for you to be within an “acceptable” weight – what prevents you from deciding to lose those last 22 lb? (Not implying at all that you should lose it btw, just intererested)

Love your work!!!!!!

Timely Harps.
I am still on a bit of high with my “self in one year’s time”. Clocked up 12,000 steps today … plus added a 1 hour workout of ‘park footy kicks’ with my 13 year old son. Must be one of the great ways to work out. Trying to keep yo my target of 70,000 steps a day. Walking to and from work every day I can … AND walking heaps more at work … staff LOVE that I am out and about every chance I get. and really …. cutting out Big Mac’s aint that difficult.
Your presentation to our group is still making a difference. Thanks

@Anonymous. He could in a sense get “fatter” if he lost those 22 pounds. He is considered “overweight” but probably has less body fat than someone at the “acceptable” weight. In other words the acceptable weight says nothing about how you should weigh. Each person’s “acceptable” weight is different and will vary depending on activity.

Thanks for explaining this


Erinn August 12, 2012 at 10:34 pm

“Or did I?”



Nikki August 12, 2012 at 10:57 pm

Umm. I was was mindlessly eating peanuts, while reading your article. I’m throwing the rest of them in the bin! Why, because all this time I’ve been seeking inspiration from your articles, I’ve actually gained weight and it’s finally hit home that I am one of ‘those people’ that you often refer to. You know the ones that actually know, discuss, read positive stuff but Never actually do!! So that’s it. I’ts time to take ACTION. Bye bye take out and hello the way nature intended us to eat!


Carmelo August 13, 2012 at 6:29 am

There’s an 84 point FIVE percent chance that you DID make up that last stat!

Some of those were very funny, Craig. Thanks for the levity as well as the info. I’ve found that awareness is the biggest factor in staying in shape. Aware of what you eat, when you eat (when hungry or not), and what your level of activity is.

Excellent! My memory of the Nutella ads is they say ‘it’s made from hazelnut, so it’s healthy’. How do people get away with these sort of statements?


Evan August 13, 2012 at 8:57 am

All true. And there are social factors to be considered too – from neighbourhood design to the casualisation of the work force.


Beach bear August 13, 2012 at 9:31 am

Thanks for putting it so simply Craig… really isnt rocket science but its still one of the worlds biggest health problems. I must admit that i am an over-thinker so i was reading intently when i got to the last point ha ha. Thanks for the straight forward in your face way you give us this info i love it so much :)


Anita August 13, 2012 at 9:36 am

Great article. I would like to add that it is not only sitting in front of TV that wastes time – the good old internet and all the social media can be just as time consuming. Then again you could be researching how to start your training regime or being motivated by Craig!

great I got a giggle and some useful facts, thanks!


Maylene August 13, 2012 at 10:55 am

Hi Craig,
I’m taking on that 20% TV time on exercise as a challenge. Thanks for the hint.


Ruth August 13, 2012 at 10:55 am



amanda August 13, 2012 at 11:04 am

Great! Thanks Craig!


agm August 13, 2012 at 12:56 pm

Is it true that muscle weighs heavier than fat? And so it is difficult for some people to be in the right weight range for their height if they have muscly body form; not a gym junky, but naturally muscly due to daily physical work activities over their life.
Thanks Ch for the good info.


Craig August 13, 2012 at 5:17 pm

Hi agm,

yep, muscle does weigh slightly more than fat and the point I was trying to make was that, if your body-fat level is in a healthy range then your weight is redundant. :)


Suu August 13, 2012 at 6:13 pm

84% chance that I’m an overthinker if I’d read that far?
More like brain-boggled to the point of having numbers and ‘facts’ swimming around in front of my face as if I’d watched a lightglobe for too long and looked away and still have that black spot in my sight for ages afterwards!
Can you underthink something for tomorrow please? KISS?
Lovenhugs to all
Suu xxoo
