With so many men now looking overweight or obese, developing a set of man boobs (or gynecomastia to give the condition its proper name) is alarmingly easy these days.
If you are self-conscious about your body and, in particular, are embarrassed about your so-called 'man-boobs', then don't be, you're certainly not alone and with the right attitude and expert advice, they'll soon become a thing of the past.
For the majority of you out there, carrying excess body fat is most likely the cause of your man boobs. Walsh says: "To be classed as healthy, your body fat should be less than 22%, and anything above this will begin to contribute to man boobs."
As with any fitness or weight loss goal, losing your moobs is all about commitment and willingness to adopt a healthier lifestyle for longer than just a few weeks.
Working out regularly is obviously going to be key to staying flat-chested, but forget about doing nothing but chest exercises.
Your workout schedule should be a sweaty mix of high-tempo cardiovascular training, like interval training or spinning classes, mixed in with weights to promote muscle growth.
To say goodbye to your moobs forever, regular exercise and, just as importantly, a healthy, balanced diet needs to become something you adhere to every day, not just when you feel guilty or down about your body.
For some men it may just be a case of losing the excess weight and the man boobs will vanish. If this isn't the case for you, however, then you still have options.
Once your exercise and diet regime has taken effect, it's important that you don't slip back into your old lifestyle, which will only undo all your hard work.
