In general, limit your consumption of sugar for better weight control (which affects energy) and steadier blood sugar. When possible, switch from refined sugar to alternatives like agave nectar. Made from the cactus plant, this liquid sweetener has a lower glycemic index and glycemic load than sugar, meaning that ounce for ounce it will keep your blood sugar more even.
Christina Giallourakis, certified holistic health counselor and owner of Inspire Nutrition, suggests substituting agave nectar for sugar in beverages like tea. Or try Giallourakis’ natural lemonade: Squeeze half a lemon into a tall glass of cold water and sweeten with a teaspoon of agave nectar.
