With so much confusion around exercise and weight loss, let’s just get back to basics. How about we use some common sense?
When we get mobile and active ie when we exercise, it takes energy.
This energy either comes from what you eat, or, if you eat the same, it will come from your body stores ie from fat.
So exercising more uses up fat, and you will lose weight.
Straight-forward enough.
NO!!!
Common sense has failed you and everyone else who pushes this line of thinking. Don’t kill the messenger. I’m just passing on the researched reality.
Exercise has a pitifully small weight loss advantage.
Mild to moderate exercise removes an average of less than 3 pounds / 1 kilogram. Vigorous exercise produces barely any more weight loss at 4 pounds or 1.5 kilograms.
That’s all!
Now that isn’t to say exercise doesn’t have other important. It does.
Exercise tones up your muscles, improves your heart, is a more effective mood enhancer than anti-depressants, helps you live longer, among other benefits. Pretty important if you ask me.
It’s just that exercise isn’t all it’s cracked up to be for losing weight.
This totally non-commonsense finding is systematically proven by a review of all the best literature on exercise put together by the most authoritative research collation body in the world, the Cochrane Collaboration. They are not sponsored by medical companies so they are uniquely independent reviewers.
The header of their “Exercise for overweight or obesity” review does indeed say…
We found that exercise has a positive effect on body weight
But buried lower down in the sleep-inducing technical details they admit how miserably small the weight loss is…
When compared with no treatment, exercise resulted in small weight losses across studies. Exercise combined with diet resulted in a greater weight reduction than diet alone (WMD – 1.0 kg; 95% confidence interval (CI) -1.3 to -0.7). Increasing exercise intensity increased the magnitude of weight loss (WMD – 1.5 kg; 95% CI -2.3 to -0.7).
The small weight loss is the same whether you exercise for 6 weeks, 12 weeks, 6 months or 12 months!
Not only that but no matter what type of exercise it is, the results are still unerringly the same.

In summary…
When someone, a gym instructor, a personal trainer, a friend, a health adviser, or even a medical authority, tells you that exercise will help you lose weight, I invite you to challenge them.
Ask them how much weight they think exercise will help you lose, and how they know? Watch them ignore your question, squirm, or outright invent stuff.
If they disagree with the study above then have them send their research proof to me. No one has yet.
Stop the myth-making.
The evidence-based reality is that, on average, exercise will indeed lose you weight. It’s just not going to lose you that much.
You got to be doing something else to shift those scales. That’s what this site is about.
