yes yes and yes. I came back from travelling having eaten a 'normal diet' for my whole life (yet albeit on the healthier side with less fried food and more home grown veg/homecooked meals etc) and being partiularly prone to spots because i had weakened my gut through stupidly eating all sorts of food filled with nasty bacteria like a dead clam. Ug, bad times.
So, i spent a year trying different gurus advice, raw vegan, sprouted grains, kefir, goji berries and all this rubbish. I cleared my skin a little because i was eating so little it gave my body a rest to heal, but ended up being incredibly weak and thin such that if i did eat any western food, or had a beer or a late night i was so weak i would break out.
And then i stumbled across a website called 'Marks Daily Apple' which basically said, "Stop eating according to fashions, idealogies and cults, and start eating the way you body has evolved/adapted to eat." Another year of research from that point and I am proud to say I no longer follow 'diets' as such, but rather the only actual diet. Whether or not i eat crap is my choice be at least i know whats what now. Its not a game to be won (ie this diet vs that diet), it is looking at your natural history, trying it for yourself, and opening your eyes to the actual place food has in ones exsistance.
Needless to say I have perfect, glowing skin if I maintain this lifestyle, but if someone wants to not jump in at the deep end because of social conditioning, give up particularly bad culprits like up dairy, grains and nuts.
I must say when i walk past people in the street with bad skin and spots i just know that such a large percentage of those poor people are doing it to themselves with what garbage they eat.
Also dont scrub yourface, wash gently with luke warm (the cooler the better) water, stop using any soaps or products on you skin, drink plenty of spring water (or any other good water) and never ever ever squeeze your stops. A diet with plenty of raw animal fats, moderate raw animal protein and suplimented with some fruit, plus daily exercise and some sunshine will teach you a lesson you will never forget.
Hell if you want 1 to 1 help i'll be happy to. After all the ONLY reason i started taking an interest in this subject was to stop getting spots. Which i did. And i was so misarable back then that ill be happy to help you if you want me to.
All the best,
david
