Good question, now this is a very difficult question because everybody is going to have an opinion on this. I am going to tell you the first thing I tell my clients before they start a wellness program with me. These are the basics.
For each meal you need to eat each of these macronutrients: Protein, Carbohydrate, and Fat. Without all 3 of these it does not constitute as a meal.
The best way to get each source:
Protein: Organic free range animals. Fish, Chicken, Turkey, Deer, Beef - all good sources of protein -- black beans, legumes, pinto beans
Carbohydrates: The best source is Vegetables - fresh organic -- sweet potatos, yams, Oatmeal, but I would stay away from breads and pastas. (if you can)
Fats: Good source of fats are: Vegetables - olive and cocunut oil, nuts, and fish.
You should be supplementing with a GOOD QUALITY multi vitamin, and a heavy metal free Omega 3 source (fish oil)
1. drink water (half body weight in oz/day)
2. cut out sweets
3. stay away from fried, processed, frozen, and packaged meals.
4. Eat more vegetables, you usually always need more
5. Have a positive attitude.
6. Anything that has 0 calories is Artificial and not made to go in your body!!!
7. Organic fruits vegetables and meats are very good for you
8. Do a cleanse every 6 months
9. Just because its "low fat" does not make it healthy
10. Learn to read labels - hydrogenized, artificial, High fructose corn syrup fructose, many other things = not healthy.
Hope this helps
