(in no particular order)

1. Balance your Omega 3s & 6s. Learn more here and here.
2. Eat a lot of antioxidants, especially if you’re exposed to a tremendous amount of toxins and bacteria, i.e. city folk, people working around pesticides or chemicals, hospital workers etc.. For high exposure people a super-supplement is often necessary; I use NingXia Red.
3. Eat very little PUFAS and an abundance of natural, saturated fats. Learn why here, here, here, here, here, here, here and here.
4. Follow the TOP 10 FOOD INFLUENCES ON YOUR METABOLISM 
5. Match your nutrition with your activity levels, daily. Most importantly your carbohydrates should match your energy expenditure; therefore, if you sit all day you don’t need as much as you do when you’re active.
6. Eat real food as it was intended to be, grow, feed & roam, etc.
7. Avoid processed soy (see here, here & here), and while you’re at it, avoid everything else processed.
8. Focus on these three oils; olive, macadamia & coconut oil
9. Avoid those items on the No-No list
10. Don’t feel guilty about eating the wrong foods. Nobody is perfect and that includes you. Stick to the plan as best as you can – measure yourself by how you bounce back from imperfections and how far you have come.
