How the hell do you not have full abs at 8%?This quote is hidden because you are ignoring this member. Show Quote
Let me rephrase being "normal". Its not healthy.
For males the main concern is lowered testosterone. Its proven when you take your bodyfat below 5% and under your testosterone can drop up to 75%. This can lead to alot of bad things.
For females it is shown that dropping below 15% can cause them alot of issues with reproduction. I know multiple fitness competitors that have taken fat levels to crazy lows and never competed again because of losing there period, lack of sleep etc.
Last but not least it can cause serious heart problems. People forget that you have essential fats (heart, liver, kidney etc) and storage fat (that fat you notice).
Its been proven repeatedly that the healthy norm for males is 10-20% and females is 18-28%.
Next time you diet yourself you should get blood work done before and after. Id be very surprised if you are hitting 3% and not doing some serious damage.
