When a 2012 study reported that chocolate milk was an effective post-exercise recovery drink, athletes and exercisers everywhere rejoiced. Not only did the findings mean that you could save money by skipping some of the fairly expensive recovery products out there, but it also gave you an excuse to drink chocolate milk guilt-free.
A similar wave of excitement – albeit with a little more hesitation – is sweeping the health and fitness realm in response to a University of Montana research paper entitled “Post-exercise Glycogen Recovery and Exercise Performance is Not Significantly Different Between Fast Food and Sport Supplement.” While the title itself may not be particularly exciting, the findings of the study carry some interesting revelations for athletes when it comes to post-exercise nutrition.
What They Did and What They Found
For the study, 11 male subjects (all recreational athletes) completed two separate time trials on a stationary bike. First the men took on a 90-minute ride, designed to deplete their glycogen stores, followed by 4 hours of rest. During this rest period, muscle biopsies were taken to measure glycogen levels.
The subjects were also given a recovery meal, consisting of either traditional sports supplements or fast food. Each of the meals was designed to contain roughly the same amounts of total calories (about 1300) and macronutrients. At the end of the 4 hour rest break, the men were put back on their bikes for a 20K time trial.
After various numbers – including performance, glucose response, insulin response, cholesterol response – were crunched, there was no difference between the fast food and the sports supplements.
Implications and Cautions
After this story first broke several months ago, many publications latched onto it. But, according to one of the authors of the study, these articles misrepresented the findings. This study is not a free pass to load up on fast food.
The positive results in the study, related to eating fast food as a means of recovery, were achieved with small portions.
You also have to consider that food contains a lot more than just calories – especially fast food. There are plenty of preservatives, dyes, flavorings and texturizers added to processed food that may have any number of negative health effects. While these additives most likely will not have any acute impact on your athletic performance, they probably aren’t doing you any favors in the long-term. So, then, you have a choice to make: If you do not typically indulge in fast food, you may consider allowing yourself this one dietary lapse as a recovery meal. On the other hand, your repulsion from fast food might be too strong to even let that slide.
Either way, the facts remain: Fast food is – depending on your personal attitude toward the subject – an acceptable recovery meal. If your dietary conscience allows and you can practice moderation, grabbing a bite from the nearest fast food establishment can provide you with a cheaper, more accessible option than the more traditional sports recovery foods on the market.
