I'm not sure it would be a best seller. People don't want to hear this advice, they want "one weird trick" and paleo diets and juice fasting and fast cures that don't involve hardwork or fewer slices of bacon
I am sure eating processed food, containing growth hormone, antibiotics, artificial food coloring, phosphoric acid, BPA (just to name w few things) has nothing to do with epidemic of weight gain. I know a female marathon runner here in Bellingham. She runs marathons in around 3:05, so she doesn't lack training of fitness, but is still on fat side. Sorry, but a proper diet is equally important in weight loss.
It's so hard to tell, are you agreeing with me again?
