I love exercise. Seriously, I’d train hard every single day if I could. That hour in the gym is often the most relaxing part of my day.
My relationship with exercise isn’t unique; a lot of people truly enjoy doing it. After a few weeks in my coaching program, practically all my clients report looking forward going to the gym.
While this feeling isn’t unique, it’s not exactly common either. Plenty of people dread exercise and going to the gym, but they do, mostly because they want to lose weight.
We’re constantly made to believe that if we want to lose weight, we need to exercise, we need so many minutes of activity per day, and we need to be in the gym “x” number of times per week sweating out the calories.
Exercise has a ton of health benefits, there’s no denying that. But is weight loss really one of them? And does counting how many calories you burn actually do more harm than good?
Let’s take a look…
Every January 1st, gyms are flooded with new memberships because if you want to lose weight, you need to exercise…right?
If exercise were the answer to weight loss, we’d all be a lot thinner. But judging by increasing obesity rates, it’s not. Here’s why:
Most machines at the gym ask your to input your height and weight, and by the end of your 30-minute sweat-sesh you’ve burned 600 calories.
Errrrrmagahd, McDonalds here I come!
But a lot more goes into measuring energy expenditure than height and weight. Things like body composition, gender, age, exercise selection and intensity all factor in as well. And that’s not even counting the hormonal environment going on inside each individual. So two people of the same height and weight, running on the treadmill for 20 minutes could burn calories at two very different rates.
Not to mention that the more often you perform the same exercise at the same intensity, the fewer calories you burn. As the body gets more efficient at an activity, it expends less energy while doing it.
Time is the one thing we can’t get back. And when it comes to weight loss, exercise alone is an inefficient use of your time.
A 2010 study by the International Journal of Obesity found that without any diet changes, it takes approximately 35 hours of cardio to burn one pound of body fat. That’s 35 hours you could spend doing something productive or spending with your family.
Instead of spending hours upon hours exercising without any dietary changes, you can simply just eat a few hundred calories less every day and save yourself a lot of time.
While the concept of whether or not exercises actually makes us hungrier is up for debate, it does appear that exercise can actually make us eat more; particularly among those who track how many calories they burn.
When you think about exercise simply in terms of “calories”, you’re essentially placing the same value on exercise that you do on food. Subconsciously, this opens the door to the belief that you can reward yourself for exercising with food.
The biggest problem is, according to a study published in the New England Journal of Medicine, people are horrible at estimating calories. The study found that when asked to self-report their energy intake and expenditures, the participants underestimated how many calories they were eating AND overestimated how many calories they were burning; both by almost 50%.
This means that not only do many people eat more calories than they think, they also don’t burn as many either.
So as you can see, exercise alone is a poor method for inducing weight loss, and the act of counting how many calories you burn through activity may actually be detrimental to your efforts.
So what should you do? Here are a few tips:
I want to emphasize that in no way do I think exercise, of any kind, is bad. Every single one of my clients perform multiple days of resistance training each week.
We just need to change our thinking on exercise. We need to stop counting how many calories we burn, and stop viewing it as the best vehicle for weight loss. Because it’s not, and viewing it as such only serves to hurt our weight loss efforts, not help them.
Focus on building a solid foundation with a good diet, while engaging in activity that you enjoy, and will benefit your health over the long term. If you do that, weight loss will come.
