Staying positive, says Dr. Orloff, is the very best thing you can do to boost your energy and promote good health.”

Avoid the four energy drains. Want to feel energetic all day long? The trick is to do things that ramp up your energy and steer clear of the ones that suck it all away and make you feel drained. Eliminate these energy vampires, and watch your vitality skyrocket:
    
     1. Caffeine. Drinks such as Red Bull, Full Throttle and Mountain Dew are loaded with caffeine. Even coffee and regular sodas contain enough to give you a buzz. It’s true that a little bit of caffeine can provide a burst of energy, but it doesn’t last long. Drinking caffeinated beverages after lunch also can affect the quality of your sleep, leaving you without much energy the following morning.

    2. Sugar. Eating too many high-sugar foods, such as candy bars, soda and ice cream, can cause your blood sugar to drop, making you want to curl up for a nap. These foods also are filled with empty calories, so you won’t feel full for long. If you’ve got a sweet tooth, choose snack options that contain natural sugars – such as fruit – for a lasting lift.

     3. Energy bars. Contrary to their name, energy bars are not the best source of energy. Many are highly processed and high in calories, making them inferior to other snacks, such as nuts, cheese and crackers. “Avoid energy bars that are filled with gooey ingredients. They might sound tasty, but they aren’t that healthy,” Moores says. “If you must have an energy bar, choose one that has 10 to 15 grams [g] of protein, 2 to 3 g of fiber and fewer than 300 calories.”

     4. Television. Curling up on the couch to watch TV might seem relaxing, but the opposite actually may be true, Kornblatt says. “Television entertains us, but it doesn’t relax us. We have to make a lot of decisions when we watch TV – ‘What show should I watch?’ ‘How do I feel about the characters?’ ‘Is there something else on?’ ‘Do I want to eat the snack I just saw advertised?’," she says. "Those thoughts are exhausting. You’ll have more energy if you turn off the TV and go for a walk instead.”
