Health problems. Lots of things that can go wrong here but I wont bother to go into too much detail because you have heard it all before. These problems are very dosage dependent and drug dependent. Enlargement of the heart is probably the biggest problem. Although enlarging your heart sounds like a good thing, its very, very bad and is what leads to heart attacks in young bodybuilders. Damaging your kidneys and liver is another relatively common problem as the body works overtime to filter out stuff that it doesnt want. Then there is the problem with natural testosterone production being shut down.
Martin, you are great, always improving your articles based on the feedback from your followers. I am the one who brought up the shorter men issue.
You wrote: `Shorter guys (below 170 cm) seem to skew the formula towards being heavier.´
I am the opposite. I weigh 57 kg at 166 cm. But what´s interesting is that I am a mesomorph that looks quite muscular and fairly lean! So, I really can´t picture myself at 66 kg while not looking like Donna Simpson.
Unlike most men, I tend to put fat not on the abdominal area but on my legs, ass and lower back.
Could it be that uncommon fat distribution patterns are a main cause of inaccurate BF % assessments?
