40/30/30 is how the Zone Diet reads - 40% carbs, 30% fat and 30% protein. That's how the Iowa caucus results came across for the Democrats. 38% for Obama, the sugars - what brightens our eyes, what gives us energy and motivates us. 30% for Edwards, the fats - buttering us up, telling us what we want to hear about change. 29% for Clinton, the proteins - for substance, strength and stability.
