Is there an ‘exercise pill’ in our future?

Suppressing production of the protein myostatin enhances muscle mass and leads to significant improvements in markers of heart and kidney health, according to a study conducted in mice. Joshua T. Butcher, PhD, a postdoctoral fellow at the Vascular Biology Center at Augusta University, will present the work at the American Physiological Society’s annual meeting during the Experimental Biology 2017 meeting, held April 22–26 in Chicago.

The researchers zeroed in on myostatin because it is known as a powerful inhibitor of skeletal muscle growth, meaning that people with more myostatin have less muscle mass and people with less myostatin have more muscle mass. Studies suggest obese people produce more myostatin, which makes it harder to exercise and harder to build muscle mass.

“Given that exercise is one of the most effective interventions for obesity, this creates a cycle by which a person becomes trapped in obesity,” Butcher said.

Obesity is linked with a range of factors that increase the risk of heart disease and diabetes, including high blood pressure, high cholesterol, insulin resistance and kidney damage. The researchers bred four groups of mice: lean and obese mice with uninhibited myostatin production and lean and obese mice that were unable to produce myostatin. As expected, mice that were unable to produce myostatin developed markedly higher muscle mass, though the obese mice remained obese even with more muscle. The obese mice that were unable to produce myostatin showed markers of cardiovascular and metabolic health that were on par with their lean counterparts and dramatically better than obese mice with uninhibited myostatin production.

“In our muscular obese mouse, despite full presentation of obesity, it appears that several of these key pathologies are prevented,” Butcher said. “While much more research is needed, at this point myostatin appears to be a very promising pathway for protection against obesity-derived cardiometabolic dysfunction.

“Ultimately, the goal of our research would be to create a pill that mimics the effect of exercise and protects against obesity. A pill that inhibits myostatin could also have applications for muscle wasting diseases, such as cancer, muscle dystrophy and AIDS,” he added.

I would just like to add that a pill that inhibits myostatin can indeed be a very helpful tool in fighting obesity among other diseases of disrepair, but I will never believe that a pill will substitute for an exercise workout. We are organic machines and, as such, need to work, not just take drugs. Let’s not get caught up chasing fool’s gold.

  1. Your comments in the last paragraph are perfect. There is no substitute for the real deal.

  2. I completely support your comment, Tony.
    There is controversy over the effects of myostatin inhibitors on the tendons that protect against muscle injuries. Our bodies release these proteins for a reason. Trying to “short cut” nature in favor of inducing artificial muscle growth or function (in the case muscle dystrophy) is likely to cause unforeseen harmful side effects. All synthetic drugs, unfortunately, cause some level of secondary complications.
    Disciplining oneself to healthy habitual behaviors will always be a necessary priority to achieve a healthier outcomes. This means good old fashioned exercise and quality nutrition remain important components in healthy living.
