Dr David Broom, senior lecturer in exercise science, spoke to health magazine, Furthermore, to explain why the harder you work the less hungry you will be.<\/strong><\/div>\n

Every athlete knows that education is a crucial part of performance.\u00a0Sport\u00a0and exercise research, insight from top trainers, science, and\u00a0technology\u00a0help you to better understand your body so you can craft a healthier lifestyle, workouts, and recovery plan.<\/p>\n<\/div>\n

According to a recent study in\u00a0The Journal of Endocrinology<\/em><\/a>, the harder you work out, the less hungry you’ll be. British researchers found that going for a run reduced levels of acylated ghrelin (the hormone that signals whether you’re hungry or not) as well as reported hunger levels in active men.<\/p>\n<\/div>\n<\/div>\n

\n
Dr David Broom, the lead study and senior lecturer of exercise science at Sheffield Hallam University, says the seemingly backwards reaction probably has to do with evolution:<\/div>\n
<\/div>\n
\n
\u201cWalking long distances or foraging at a low intensity and feeling hungry would give you the drive to find food. However, if you encountered danger and had to flee or fight, the last thing you want to be worrying about is your hunger.\u201d<\/div>\n<\/blockquote>\n
<\/div>\n
\n

Researchers have found that going for a run reduced both. “Blood is shunted away from the stomach when you exercise, so there is less supply of acylated ghrelin,” explains Broom, senior lecturer of exercise science at Sheffield Hallam University in England.<\/p>\n

But workout length didn\u2019t make much of a difference: As long as it was at the same easy to moderate pace, guys who finished a 90-minute run had the same suppressed ghrelin levels as after a 45-minute run. Essentially, your ghrelin dips to a certain point and remains steady along with your pace until you stop moving, at which point your hunger hormone levels will start to rise again, Broom explains.<\/p>\n

The interesting part, though, comes when you kick the intensity up a notch: athletes felt less hungry post-workout when they had a heart rate above 75 percent of their max compared to below it, no matter the duration. In fact, Broom adds that even a 30-second sprint proved intense enough to affect hunger hormone levels.<\/p>\n<\/div>\n<\/div>\n

\n
While the study was small and exclusively on men, previous research supports exercise\u2019s repression of ghrelin and appetite, and Broom notes that his team\u00a0has shown\u00a0these results would probably be the same for women.\u00a0If you\u2019re trying to curb your calorie intake, sweating at a higher intensity may help.<\/div>\n
