I'm not going on a diet, I am embarking upon a complete lifestyle change.
And this is what most don't get. You are stuck in a corner, you try to fight back with a diet change you hate with your guts and after a while, you go back to the same damn routine you once were. Going on a strict diet may hasten the process a bit but it doesn't do much in the long run. Been there, done this many times, didn't work.
Changing the whole lifestyle is the only way to sustainable metabolism.
Kudos to you!
Not wishing any good luck, 'cause you ARE gonna do it!
