If you're a man and have man boobs, then you know it's time to hit the gym.
However, if you're a boy in the UK, you can just get them surgically removed.
Sounding like an urban legend, this is a true story according to the Daily Mirror. Obesity in boys and teens are leading to increasing and abnormal hormonal changes.

It causes firm, tender female breast tissue to grow under the nipples. "
