I keep hearing a lot of my Facebook friends talk about spending several hours a week in the gym doing cardio in an effort to lose weight. The fact I keep hearing this means that they think doing more cardio is the most effective way to lose weight. I’m not really sure where that myth started, but as far as I’m concerned it spread like the plague.
Now let me be clear here, I’m not saying cardio is bad, but for weight loss purposes, it’s not really needed. Now there is a time and place for cardio but for the level of leanness you want to get to, it’s probably not even necessary. For weight loss, just stick to the basics, calories in vs calories out. Whether you walk a mile or run a mile, you burn about 100 calorie or so. You need to create about a 500 calorie a day deficit below EE (energy expenditure) to lose 1 pound of fat per week. If you did the math properly, that means you would need to log 5 miles a day 7 days a week without increasing your calories if you attempt to do this through cardio alone.
I’m not the smartest guy, but it’s much easier not to eat 500 calories than it is to eat them and try to burn them off. If you don’t believe me, try and do it. I could easily consume 2 Snickers Bars (about 500 cals) before you could run a mile. This extra exercise for weight loss can only provide a significant benefit if you keep your calories in check.
The next problem you have is the time factor. We live in such a fast paced world that there never seems to be enough time in the day. If knowing you have to run 5 miles a day just to lose a pound stresses you out, then it’s not worth it. And what happens if you miss a day, which you will?
Next, as you become more efficient at running, your body doesn’t burn as any calories for that same hour thus requiring you to have to run longer which once again requires more time that we already don’t have enough of.
The more you exercise the more likely you will get hungry and the more tempted you will be to overeat (or at least eat more than you were planning). Cardio CAN help if you keep those calories in check, but there is a cath 22. Even though you’ll burn more calories and lose weight faster if you add in extra exercise, you’ll also be tempted to eat more food. This is simply your bodies way of doing it’s best to keep you at homeostasis.
So to sum things up, you have to keep the calories you eat in control if you want to see the full benefit from adding in cardio sessions. Exercise for weight loss can be effective IF and only IF you’ve got a handle on your calories. And remember when it comes to weight loss, stick to the basics - calories in vs calories out. Usually the simplest answer is the best answer.
