To get more energy, you have to produce it. Stop complaining that you have no energy to workout, to eat right, to pack a lunch, etc.! How do you expect to HAVE energy, when you continue to do LITTLE or NOTHING about it? Your body LOVES to do no nothing. Then it doesn't have to work as hard. That means you don't burn as many calories. That means you have a harder time losing weight. That means you increase you body fat. That means loss of lean muscle. That means you get out of shape real fast. Force your body out of that "comfort zone." Yes, if you're particularly low on energy, it is critical for you to get off your duff and get moving. Yes, there is the initial stage effort, even to just go far a 5, 10, or 20-minute walk. But, it gets easier. You must know that. Even after a few workouts, you'll easily notice an increase in your energy levels. Strength training makes you stronger, so you can do more vigorous tasks without undue muscular fatigue. Aerobic exercise conditions you heart and lungs, delivering nutrient-rich blood to working muscles and organs. Ultimately doesn't have to work as hard just to pump blood. And don't forget sound nutrition. The right balance of nutrients, at the right times, in the right amounts gives you the fuel you need to function at your absolute best every day. But high energy won't be handed to you on a silver platter. Go make it happen!
