If you're just beginning your journey to healthy living, start small, don't jump in head first and try to; eat right, count calories, stop eating after 7pm, workout ,give up soda, and chocolate all at once, I promise you, you'll fail. You'll wake up with a chocolate chip cookie in one hand and Cheeto's in the other wondering "what the hell?" Try starting small, I call it stack building goals. Make a commitment to drink nothing but water for the next week. Once that goal has been met, make another commitment. Do not overwhelm yourself, ease yourself into healthy living, because it's a huge adjustment. Remember this is a marathon, not a sprint, or a race, slow steady endurance will get you there.
