What should I eat?
With all the fad diets that emerge every year it's tough to know which one will work for you. The best thing to do... stay away from fad diets. None of these are designed for longevity. That's why they're fads. What you, need to do is stick to the basics straight from CrossFit's "World Class Fitness in 100 words". Eat meats, vegetables, nuts, seeds, some fruit little starch and no sugar. If you do this you'll be fine. Then you can learn to adjust the quantities based on your needs from there. But for now, as a start, just eat real food, not too much, mostly plants.
