Get into the habit of starting your day with a big glass of water with fresh lemon juice upon waking up. Lemon is cleansing, alkalizing and revs up your metabolism. Every function in our body runs on water, including elimination and cleansing. Water helps with healthy digestion, regularity, detoxification, mental clarity, energy and satiety. Aim to drink half of your body weight in ounces throughout the day. More if you are active or sweating.
