I agree, run, run, run!! And cut out that junk food stuff.
My experience with losing fat is that do not take a harsh diet for long time, which is bad for your health, I had experienced losing hair because of that before
Best approach is to lose fat slowly through balanced diet and some training, if you lose weight very fast through a harsh diet you will regain it very fast after stopping it.
Well, My story started 2 years ago,
There used to be a hill right infront of my previous house, The hill had 2 hiking tracks, One led you straight to the top, while the other led you around the hill.
I used to go hiking there everyday from 5pm onwards, sometimes 1.5 hours and sometime 2 hours. And in just a months time, I had actually lost around 11 kgs.
And well now, I have dropped from being 77kg to around 64kgs, This was the best way for me
