Don’t Always Believe the Science

Don’t Always Believe the Science

Science has given us some amazing inventions over the centuries. Personally I’m a big fan of the light bulb (thanks Thomas) and the Wright brothers were certainly having a good day when their flying machine finally took to the air at Kitty Hawk all those years ago. But I guess the scientific breakthrough at the very top of my list was created by that little-known inventor, designer, engineer and scientist… Ogg.

    Who would have guessed all those millennia ago when Ogg emerged from his cave to invent the wheel that not only would he make his and Mrs Ogg’s life a crap-load easier but all these years later my favourite toy (my motorbike) would be totally dependant on his neolithic creativity and invention.

    So thank you Ogg from the bottom of my high-octane heart.

    Science impacts on virtually every part of our lives. It is something we consider, negotiate and benefit from every day. It’s also something which misleads us and confuses us from time to time. Ask five experts one question about nutrition and your head might explode from the variety of answers. Ask ten conditioning coaches or exercise scientists one question about training and we might find you two days from now sitting in the corner sucking your thumb. Or visit ten medical experts with one condition and you’re likely to get numerous diagnoses and more prescriptions than you can poke a stick at.

    Part of the problem with some scientific ‘facts’ is that they aren’t facts at all; they are scientific theories.

    Every day somewhere in the world another scientific ‘fact’ bites the dust. It is exposed for the fraud that it is. I could give you a hundred examples of this but I don’t want to put you to sleep, so instead I’ll give you a few things to chew on which might be relevant and of interest to you.

    1. Height/Weight Charts

    To say that a person should weigh a certain amount because they are so many inches tall is not only misleading but potentially dangerous. Stupid in fact. At best, these charts are vague indicators or guides of what may be a healthy weight range for some individuals. We have a rugby team here in Melbourne, Australia called the Storm. If you were to compare the weight of the individual players against the ‘scientific weight recommendations’ for their height you would discover that close to one hundred percent of the team would be classified as overweight or obese. And therefore all fall into the high health risk category. When in reality the only immediate health risk to the Storm boys is getting their heads ripped off by some unhappy neanderthal opposition players. According to ‘science’ I should weigh somewhere between about 12 kgs (26lbs) and 22 kgs (48.5lbs) less than I do right now. My body fat as I write this is 16% (healthy). If only I was seven feet tall… my weight would be perfect!

    2. BMI

      BMI stands for body mass index and it is a scientific formula used to classify people on a scale from underweight to obese. The equation is:

      Your weight in kilograms divided by your height (in metres) squared.

      Here’s my BMI equation

      91 kgs divided by (1.78m x 1.78m) = 28.72.

      This result tells me that I am significantly overweight and borderline obese. Hmmm.

      This science doesn’t factor in how much muscle individuals have.

      Check this out:

      Subject one:
      Male
      Height 180cm: (5’11”)
      Weight 100 kgs: (220 lbs)
      Actual Body-fat: 12% (low)
      BMI classification: 30.9 = FAT!

      Subject two:
      Male
      Height: 180 cm (5’11”)
      Weight: 80 kgs (176 lbs)
      Actual Body-fat: 25% (high-ish)
      BMI classification: 24.7 = NORMAL!

      Scientific crap.

      3. Girth Measurements

        The other day I was chatting with one of my trainers who asked me what my waist measurement was. She wanted to see how I rated on the scientific table which estimates my health risk (potential for disease) based on my waist measurement. According to the ‘science’, blokes with a waist measurement over 40 inches (101.6cm) are in trouble and girls with a waist measurement greater than 35 inches (88.9 cms) are at much higher risk also. Fortunately I’m a fair way under the danger zone but this science is flawed also. It’s vaguely indicative but by no means absolute as it doesn’t factor in the height of the individual. Surely a 40 inch waist on a guy who’s 5’4″ can’t be compared to a 40 inch waist on a guy who’s 6’7″? Well, apparently it can. And then we’ll call it a health risk assessment.

        Is waist measurement an indicator of potential health risk? Sometimes. For some people. Is it good to use a ‘set figure’ (in this case a 40 inch waist measurement) to evaluate the potential health risk for an entire population? Er… nope. Could a bloke have a 35 inch waist and be a higher risk than another bloke with a 40 inch waist? Of course.

        4. Recommended Calorie Intakes

        Dr. Bumnuts: “Okay, let’s see Mrs Smith… you’re 5’6″, you’re 42 years old, you currently weigh 70 kilos (154 lbs) and you have a sedentary job. Therefore you need 1,650 cals per day to maintain your current weight and 1,150 cals per day to drop down to 65 kilos (143 lbs) over the next ten weeks.”

        This almost sounds plausible. And if Mrs Smith expended the exact same amount of energy every day (1,650 cals worth of energy in this case), then the expert would be speaking the truth. But naturally our energy expenditure (how many cals we burn) can and does vary greatly from day to day. If Mrs Smith spends Saturday hiking, rock climbing and wrestling bears (as she does), she might need 4,000 calories just to break even for the day. But on Sunday as Mrs Smith and her sore muscles recline on the couch for the entire day, her energy needs will be drastically reduced – perhaps to as little as 1,200 calories. Same body – different needs. Bodies requirements vary from day to day which is why I always encourage people to learn to drive their own body rather than just following some generic one-approach-fits-all driver’s manual. The Point? Our energy needs (calorie requirements ) are not ‘set’ so consuming the same number of cals each day is not necessarily smart science.

        5. High carb, Low carb, No carb, My head hurts.

        Advertising

          I’m not going to explore this debate in detail here but I will say that there are numerous books, studies and experts which (who) totally contradict each other on this subject. The interesting thing is that many of the conflicting theories on the matter are backed up by indisputable ‘scientific fact’. Sound scientific research. Sure. Sometimes scientists are compelled to find a way to support their hypothesis. If you know what I mean.

          6. Australia the Fattest Country.

          A couple of weeks ago here in Australia we were informed by the scientists that we are now the fattest country in the world. Here are two excerpts taken from a leading newspaper Melbourne Herald Sun:

          “AUSTRALIA is the world’s most overweight nation, ahead of the notoriously supersized Americans, according to a new study.”

          ” The report, released ahead of the federal government’s obesity inquiry, presents the results of height and weight checks carried out on 14,000 adult Australians nationwide in 2005.”

          So in a country of 21,000,000 people they tested 0.06 percent of the population which means that they didn’t test 99.94 percent of us! I have two questions:

          1. How do they know that the 0.06 percent is representative of the 99.94 that they didn’t test?

          2. Why would they use an assessment (height/weight chart) which is scientifically flawed?

          Science is an incredibly valuable and necessary part of our existence, survival and development here on the big blue ball and I’m passionate about it. I’m also passionate about not being mislead or misinformed. We can learn and benefit so much from so many clever people in the world of science but like anything that involves humans, it’s flawed.

          7 Ways To Make Exercise Fun For Everyone

          7 Ways To Make Exercise Fun For Everyone

          From Atkins to Paleo to eating gluten-free despite not being one of the rare few people afflicted with celiac disease, fad diets are everywhere. It drives me crazy because I believe these diets do more harm than good. Your body is made up of a variety of vitamins, nutrients, and minerals, and losing weight healthily isn’t possible when you fill your body with unnecessary synthetic plastics, sugars, and powders. There’s no easy button in life.

          What you need to do is exercise, which isn’t very appealing to many people. Workouts take work, so there’s already a stigma involved in going to the gym. Starting a healthy workout regimen becomes easier when you make it fun. If you want to live long and prosper, get off the couch and try these methods to turn your workout into a playout.

          1. Take the scenic route.

          Walking is an easy way to transition to a healthy lifestyle, and it’s free. Not only do you burn calories (check out this calculator for how many calories you burn based on your weight), but you see the world in a different way. Hiking in nature is great if you have access to it, but don’t let living in an urban area deter you from walking.

          Whenever I’m creatively stuck I get my head straight by walking a couple of miles. It’s also how I discover new paths, meet new people, and stumble upon hole-in-the-wall spots I never would have found otherwise. You could drive past the same place every day and never appreciate the beauty, nor even notice it’s there.

          2. Distract yourself.

          No matter what exercise routine you choose, use the time to meditate. You may wonder how marathon runners are able to put so many miles on their bodies. It’s because the pain from running that you avoid is something they’ve learned to harness to enter a transcendental state. If you’re aware of the benefits of meditation and exercise but don’t have time to do both, you can combine them, killing two birds with one healthy stone.

          3. Listen to music or podcasts.

          There are few experiences in life more pleasurable than turning up the music and drowning out the world around you. With so many podcasts and music apps available on your smartphone, you can easily find entertainment options perfectly suited to your personal tastes. Never worry what people may think of you when working out;instead, crank up the volume and get lost in your own world. You’ll be in shape before you know it.

          4. Bring a friend.

          Some people can’t go anywhere alone. While I highly recommend dining out and seeing a movie in a theater alone, having company while exercising is very helpful. It allows you to pace yourself with someone else, and gives you a coach to motivate and push harder than you may have on your own.

          Many exercises are safer when done with a friend, and some sports can only be played with another person. Involving others in your goals can mean the difference between success and failure. Just remember to continue exercising if the other person flakes, or they’ll be in control of your health.

          5. Accessorize.

          There are accessories that can make exercise easier, and sometimes buying a new toy can add some much-needed fun to your routine. With apps like RunKeeper and Nike+, your smartphone is capable of tracking your vitals and progress. Wrist weights can add a new dimension to your workout, and, if you exercise at night, a headlamp can help you see what’s in front of you so you don’t trip.

          For urban runners and power-walkers, one of the biggest obstacles is other people. It’s difficult to get in your meditative zone and enjoy your music when you constantly have to dodge people. To resolve this vexing issue, Runbell, a startup in Tokyo, has developed the runner’s version of the bicycle bell. With this lightweight brass bell warning people you’re approaching from behind, you’re free to maintain your transcendental state while continuing your workout. Head to their Kickstarter campaign to pledge your support.

          6. Compete.

          A little healthy competition can motivate you to push yourself further in your workout regimen. There are apps like Zombies, Run! which turns your run into a video game, and MyFitnessPal which allows you to connect with others in the exercise community. Whether you’re directly competing with a friend, an online community, or against your previous self, setting goals is the key to reaching them. Running with no destination can feel like an impossible task, and it’s easy to get distracted.

          7. Relax.

          The best part about exercising is how much you enjoy the downtime. If you think laying on your couch all day is enjoyable, it has nothing on that hour you spend as a couch potato after a rigorous workout. Jay-Z said it best, “in order to experience joy, you need pain.” The harder you push yourself while exercising, the better you’ll feel when you’re relaxing.

          Advertising

          With that said, don’t relax too much, or it loses the effect. It’s okay to indulge every so often. Treat yourself to some junk food you’re craving, imbibe a drink here and there, and spend a day vegging out on your couch. Staying healthy doesn’t have to be torture. Just turn down when you can and dedicate some time to better the health of your body. You only get one.
