KEEP HYDRATED
The general population probably thinks this sounds like a broken record when it comes to the whole water thing, but it really is important. Drinking the recommended eight cups of water a day will help your body function at peak performance levels.
DESTRESS YOURSELF
Stress raises the amount of cortisol in your body. Cortisol is a hormone that tells the body to hold onto fat in case of a stressful situation (think more natural disaster-level stress, not a bad day at work-level). Experiment with yoga or meditation as ways to lower stress levels and clear your mind.
DECREASE DIET SODA
Although it's low in calories and seems like an easy swap for high calorie beverages, diet soda may actually have adverse effects on your metabolism. Water and seltzer are better options, but if you must drink diet soda, limit your consumption to two cans per week.
Getting a least seven to eight hours of sleep every night is crucial to a healthy metabolism. Anything less can adversely affect your body's ability to burn calories. Surprisingly, excess sleep may do the same thing. It's best to keep a consistent bedtime and wake up close to the same time every morning.
INCREASE WEIGHT BEARING EXERCISES
One pound of muscle burns 35 to 50 calories, while one pound of fat burns a measly 5 to 10 calories. Building more muscle can increase your body’s basal metabolic rate (BMR) by up to 40%. There's no need to hit the weights hard, either, simply using light weights at high repetition has been proven to tone muscle and burn fat.
Aside from curing workout boredom, interval training allows you to burn more calories in less time. This is a great way for busy people with less time to get in a maximum workout.
Take your pick: Jalapenos, chili, cayenne, habanero, etc.. These fiery little guys contain capsaicin, which is why you get a burning sensation in your mouth when you eat them. This same effect is created internally, causing a calorie burn for about 30 minutes afterward.
