The Calorie Myth / Smarter Science of Slim - Jonathan Bailor

Fat Burning Man - Abel James

I cannot recommend these two guys highly enough for how much they have helped me in my transition towards living better. Not only are they both extremely lovely and supportive guys, they are also deeply passionate about helping people live better, they walk their own talk and they provide a lot of information based on science while also staying open-minded and not engaging in shouting matches (see a conversation between them here).
