Low-impact exercise helps obese boys burn more fat

Hey, look! It's another sh** for brains study.
"For obese boys, lower-intensity exercise like walking may be better at burning fat than more-vigorous workouts, a small study suggests.

In exercise tests of 30 thin or obese 12-year-old boys, French researchers found that obese boys burned the most fat when they worked out at a modest intensity -- akin to riding a bike on level ground.

Once the activity became more challenging, their bodies began to use substantially less fat compared with normal-weight boys...

During the tests, the researchers measured the amount of oxygen the boys inhaled and the amount of carbon dioxide they exhaled, which allowed them to estimate how much fat the boys were burning at a given exercise intensity.

he researchers found that at lower-intensity levels, thin and obese boys burned fat at a similar rate. But at higher intensity levels, obese boys' fat-burning rate lagged behind the thinner boys' rate. Moreover, obese boys hit their maximum fat-burning potential at a fairly low intensity of exercise.

The reason for the disparity may have to do with muscle, according to Zunquin's team."

Look up the so-called anaerobic threshold, you stupid, stupid researchers.
