Nutrition is tricky. Not only is there individual variance on the physical level, but there are some very deeply ingrained social and environmental factors that play a role in eating habits.
Add in the social stigma associated with being overweight (be it real or imagined), and nutrition quickly becomes a topic best avoided in polite company, along with religion and politics.
However, if you just want some general rules for eating a bit better and some resources for further study, here you go.
The Crossfit Prescription for nutrition boils down to:
Base your diet on garden vegetables, especially greens, lean meats, nuts and seeds, little starch, and no sugar.
From working with athletes, here’s a few other important pointers:
– Get enough Sleep- Not getting enough sleep wrecks havoc on fat oxidation, mental and physical performance, etc. Do yourself a favor, get enough sleep.
– Take a multivitamin- Odds are very high that you don’t get all the vitamins and minerals that you require from your food. Take a “once-a-day” multivitamin.
– Don’t rely on willpower- If you want to eat healthier, don’t have unhealthy food within easy access. Willpower inevitably fails. Make it as easy as possible to achieve your goals, especially when starting out.
