So now we have this piece of utter nonsense:
Firstly, let get one thing straight. Activity and exercise are not the same thing. Going for a walk is not exercise, it’s just an activity. Bear that in mind if you want to lose weight.
When i walk, which i do briskly, i burn 180 calories an hour. That’s an activity. My heart rate barely ever goes above 100bpm.
When i cycle, at bottom to middle of zone 2, i burn over 360 calories an hour. This is light exercise.
When i cycle at the top of zone 2 / bottom of zone 3 i burn over 450 calories and hour. This is normal exercise.
The difference is what it makes your body do afterwards. The exercise will put into action changes in your body in the recovery period which will make your body far more efficient at burning calories and will also raise your resting metabolic rate, burning even more calories. Activity doesn’t do anything like that.
Exercising for 2 hours a day, i can easily burn 6300 calories a week. That equates to burning 36.4kg of fat a year. That’s 5.7 stone of fat. And that’s just in the exercise period, that doesn’t begin to factor in the extra calories that will be burned in the recovery period due to the exercise, or the increase in resting metabolic rate due to the exercise.
But if i was to go for a brisk walk for two hours every morning i would only be burning 14 kg of fat a year.
I hope you can see the difference?
But even still, if everyone who is overweight just did 2 hours of brisk walking a day that would make a huge difference over a year. Especially considering that i’m only 9.5 stone in weight and the heavier you are the more calories you will burn when you walk.
How do you know what a brisk walk is? Buy a heart rate monitor and use it every time you go for a walk. Buy a good one that you can program your weight into with GPS tracking for speed and distance as that gives you a more accurate read on calories burned. Garmin make great heart rate monitors. Yes, a good one may be expensive, but it will give you many years of happy healthy fulfilled life in return. It’ll be one of the best investments you’ve ever made.
A good, fully GPS, whistles and tinsel, sports watch that tracks everything you do will make you realise just how little you are actually doing. We can so easily convince ourselves that we’ve just walked 8 miles at a brisk pace but a good sports watch will soon tell you that you only walked 5 miles at slow pace. There’s no cheating with these things.
Anyway, for these so called experts to be saying that exercise (and even activity) is no good in the treatment of obesity, one has to ask just what their agenda is. Because i would welcome the chance to go on national television with them and debate this live for the whole country to see. The science is solid in what i have written above. 1kg of fat is 9000 calories. If you burn 6300 calories a week then you will burn 36.4kg or 5.7 stone of fat a year – at least. And as i said above, these figures are for me at 9.5 stone, the heavier you are the more calories you will burn.
Granted, most people could not go out today and start burning that amount of calories straight away. I certainly couldn’t when i bought Waldo last October. But 6 months of riding with Waldo and 6300 calories a week is easily doable. A bit more each time you exercise, a bit faster, a bit further, and within 6 months most of us can easily be burning a huge amount of fat off our waistlines.
Waldo is my ‘Giant Defy 1’ road bike, in case you were wondering.
But then i hear people say, i haven’t got two hours a day to spare. Well i beg to differ. Throw the television away for a start – there’s nothing on it that will make your life any good whatsoever, you’ll just sit there eating crap, drinking crap staring at it going brain dead, staying up late and not getting enough sleep. Not getting enough sleep is a cause of obesity and if you seriously want to lose weight then you need to get a good night’s sleep every night, and staring at a back lit screen before you go to bed does not allow you to get a good night’s sleep. Go to bed at 7pm having read a book for an hour first, and get up at 3.30 and go for a bike ride when there’s no traffic about and the air is cleaner. Stop driving or taking public transport to work and cycle there instead, and start taking detours as you get fitter and faster to make the journey longer and burn more calories doing it. Get a bike rack with big paniers and do your shopping using your bike instead of your car. Where there’s a will, there’s a way.
But to say that exercise is no help in treating obesity is just total nonsense.
And the other benefit of exercise is that it improves both your physical and mental health at the same time as burning loads of calories. You will feel younger, happier, more enthusiastic for life. What’s not to like?
I will discuss the diet part of the above BBC article in my next post. Cause that’s a load of nonsense as well!
