Unlimited Muscle Growth
When the Hoekstra family adopted their son Liam, they did so knowing that his difficult and premature birth might lead to a host of medical problems down the line, but happily the only thing that seemed odd about the little boy was that he was eating all the time but never gaining weight. As it turned out, Liam was eating big but staying small because he was turning all that food into muscle—he was able to support his own weight with his arms at the age of five months, and at nine months was climbing up and down stairs. Liam has an extremely rare condition known as myostatin-related muscle hypertrophy, meaning that certain proteins that would normally inhibit muscle growth just aren’t present in the same levels in his system. Even better, as far as doctors can tell, there’s no medical downside to his condition, unless you end up having to look after a superhuman baby that eats six meals a day and can crawl out of any playpen designed by man. Today, Liam is six years old, in perfect health, and making a name for himself in grade-school wrestling matches.
