Is the Fat Burning Zone a Mythical Creature?

Is the Fat Burning Zone a mythical creature?

It must be! Otherwise, all those people plodding along on the treadmills at the gym would be in great shape. Like a beautiful, sparkly unicorn, we want to believe that it exists but the concept of the fat burning zone has been regularly misinterpreted and misunderstood.

The fat burning zone theory is that lower intensity exercise, at about 55% – 70% of maximum heart rate, burns more fat. Basically, your body burns more fat at a lower intensity of aerobic exercise than it does at a higher intensity. This sounds good in theory. After all why work harder if you don’t have to, right?

The misinterpretation of this theory happens because there is a difference between percentage of fat burned vs. actual fat burned. In reality, you burn a higher percentage of fat at lower intensities but generally more fat overall at higher intensities. Your body draws energy from two sources, fat and glycogen or stored carbohydrates. The percentages of these two fuel sources vary depending on the intensity of your exercise.

At a lower intensity, you may burn 60% of total calories from fat. And at a higher intensity only 45% of total calories from fat. On the surface, that seems like lower intensity would be better. But at a higher intensity you burn more calories OVERALL which bumps your actual fat calories up even though the percentage is lower.

For example:

The numbers above are just for example purposes but hopefully, you get the point. Percentage vs. actual are very different. Lower intensity exercise has its place in a workout program but if you’re relying on it to help you burn fat, it’s not the best idea. Circuit or interval workouts are efficient and help you burn more calories in less time.

Stop searching for the mythical creature! To truly burn maximum fat, focus on building muscle with a comprehensive strength training program and healthy eating habits. These will do far more to help you reach your goals then chasing the unicorn at the end of the treadmill!

Happy Exercising!

Is High Intensity Always the Way to Go?

High Intensity Workouts are a Good Addition to an Overall Fitness Plan

There’s no denying the popularity of high intensity interval or boot camp style workouts that promise to torch fat, kick your butt and get you in great shape. You can find local classes, gyms or even online videos everywhere. These workouts can be as quick as 7-10 minutes or as long as a 1-hour class and if done right, will leave you feeling like you want to sprawl on the floor and not move the rest of the day. The idea that you can get in killer shape quickly is appealing to so many people. How could it not be, right?! The intensity of the workouts makes for great Instagram and Facebook posts too! But is working at such a high intensity all the time, even for 10 minutes, a good idea?

Steady state cardio seems to have fallen out of favor in recent years. After all, why do something that takes longer and isn’t as effective as a HIIT workout? But high intensity training is tough on your body and often recovery takes longer than most people allow for themselves. My 44-year-old body does not recovery from that kind of workout in just a day! And a number of my clients have the same recovery challenges.

If you’re trying to lose fat, often you’re restricting your calories in general and sometimes your carbs. This could make it difficult to get through a very intense workout. You need those carbs! If you’re trying to improve speed or sports performance then high intensity workouts are important. If your primary goal is fat loss then strength training and diet should be your new best friends. High intensity workouts are fine as part of an overall fitness plan but not ALL THE TIME!

As with so many other things, the old saying “Everything in moderation” applies here too. Definitely include high intensity workouts in your fitness plan but don’t make them the whole plan.

Here’s a 9-minute interval workout you can do at home… But only once or twice a week!

Do each exercise for 30 seconds moving immediately from one to the next.

  1. Plank
  2. Star jacks
  3. Push-ups
  4. Curtsy lunges
  5. Crunches
  6. Side-to-side pushups
