I was diagnosed with Type 2 diabetes last year. Paleo is very good for my blood sugar, and I have lost 60 pounds pretty effortlessly.
I do not eat with my hands or grunt (much). I eat meat, eggs, some dairy, lots of veggies, nuts, and a little fruit. I count carbs, and grains and sugar are so high in carbs that they aren't worth the cost. I 'cheat' once in while with small portions of pasta, barley, popcorn.
I don't worry about fat too much--fat satisfies, and makes things taste good.
I just haven't been the same
since that house fell on my sister.
