Take notes on how food makes you feel after you eat it, and several hours later. Is it nourishing you? Filling you up? Do you feel energized for several hours? Clarity can only be gained after analysis.
I have tried going vegetarian, vegan, no carbohydrates, gluten free, low calorie, low fat and also raw! The diet that serves my body best is a Macrobiotic lifestyle. The premise of this nutritional plan is that your body stays balanced with Yin and Yang (acidic and alkaline) so that it is in a neutral state.
