Eliminate massive amounts of processed foods such as white sugar, white rice, and white flour.
Also limit things made with white flour such as pizza, white bread, biscuits, tortillas, pancakes, and other stuff that is simply delicious.
Limit intake of white potatoes, and choose when you can sweet potatoes and yams.
Rather than white rice, choose brown rice.
Rather than hard liquor, choose a red or white wine for your evening drink.
