Sad that it's gotten to the point where he has to copy/paste all that info everytime before anyone will listen...
MG has helped me out on my diet exponentially, and I in no way consider myself to be a "guru", but by the time you are done consuming your two "meals" of oatmeal and toast, I've eatten ~900 calories, 34g Fat, 60g of Carbs, and 100g of Protein - and I'm 5'9 170lbs!
It sounds like your weight loss was from a total lack of nutrients. Do you think 160g of protein is enough to support your goal of gaining lean muscle?
I reccommend further research...
