Ironsluggo is correct!

It is all about the math and percentages. Lower intensities burn more fat so if you're just sitting around the house you're actually burn almost all fat to fuel your body. But how many total calories did you actually burn? Nobody ever got thin and healthy by sitting around. As the intensity rises so the fat-burn percentage lowers but in the end the total calories burned make the total calories from fat greater.

Intervals are a healthy way to do it. It mixes things up and keeps our bodies guessing. This helps in a lot of different ways.

Everyone just needs to keep at it! Maybe some days its going to be better to do something at a lower intensity than nothing at all because the pace or intensity seems to much to handle.

Thanks, IRONSLUGGO! That's super helpful, too!

All callers agree... being lazier isn't going to help.

Hey, Just want to clarify...the fat-burning zone is not a myth. Rather it has been misrepresented.

When we exercise our bodies need fuel. Fuel comes from either fat or glycogen (sugar/carbs). (We may also break down muscle protein but that is a different post).

Low intensity exercise will use a higher percentage of fat for fuel rather than use glycogen. Higher intensity exercise will use a higher percentage of glycogen.

Presented as such it seems that we'd burn more fat at a lower intensity. This is the misrepresentation. Given that the amount of time exercising is the same, higher intensity exercise will burn significantly more calories. While the ratio of fuel comes more from glycogen, the total amount a fat burn is still higher.

There is more but just wanted to clarify quickly.

That said, to optimize our bodies efficiency we should be working out at varied intensities. Some aerobic activity should be long and slow, sometimes do intervals or HIIT, sometimes do steady state at a moderate intensity.

Hope this helps.

Your gut was right - why work at a slower pace and burn less calories? And they don't burn fat calories. Silly machine makers.

When the metabolism starts slowing down as we age, it makes it harder to keep the lower weight we had in our 20s and so. Just make sure you don't restrict too much and keep at it!

Thanks! My gut says you're totally right. It just makes no sense to me that you'd lose more bodyfat while burning fewer calories.

I am doing a very good amount of weight training. It's part of my regular lifestyle, too. I like it because it shows very satisfying visible effects and there is nothing wrong with a little "vanity motivation" if it's for a good cause and within reason.

"Fat Burning Zone" is a myth. There is absolutely zero scientific proof anywhere that demonstrates a higher loss of fat when people exercise at a lower target rate.

Are you doing strength training? Adding that to your cardio will help you build lean muscle mass, which boosts the metabolism. You might gain some "weight" but it will be a combination of denser muscle replacing fat and those muscles soaking up water; it's not gaining fat.

And make sure you're eating enough to fuel the body - don't restrict and overexercise, that can be just as bad as overeating and underexercising. Finding that balance is difficult, but you must eat enough to fuel the body.

I've been a cardio-hound all of my life. I've also been lean all of my life. Now that I'm in my mid-30's, however, I've put on a handful of pounds even though my lifestyle hasn't really changed. I'm having the damndest time getting those 5 pounds off! I'm struggling. I'm restricting my calroies, increasing my daily activity, I'm doing all the basics right, but the padding is staying put. So, I'm looking for that extra knowledge I need to break this up.

I'm wondering if maybe I'm working out too hard. I've *always* gone for extended heart rates above 180 and I still do, but I can't help but notice that the "weight loss zone" is much, much lower.

Should I be easing up? Could that help?
