Studies conducted at The Nutrition Institute at the University of Tennessee suggest that consuming dairy may help your body metabolize fat more efficiently. Other studies have shown that increased calcium intake from dairy products (though not from supplemental calcium carbonate) caused study participants to poop out more fat as opposed to it sticking around on the body.


It’s important to remember that you are unique: Everyone was born with a different biochemical make-up. You have trillions of little energy factories called mitochondria that provide the fuel to run everything in your body. If you can remember high school biochemistry class, you know mitochondria convert the oxygen you breathe and the food you eat into energy for your body to use.
That doesn't mean you have to live on the high-protein Atkins diet. But you should make sure that 10 to 35 percent of your total daily calories comes from protein. So if you're on an 1,800-calorie diet, 360 to 630 of those calories should come from lean sources of protein, such as fish, chicken, low-fat cheese, yogurt and legumes. "Aim to have a serving of protein, such as nuts, a small can of tuna, or a piece of low-fat string cheese, at every meal and snack," says Hampl.
Clocking in at caffeine counts higher than a cup of coffee, kola nut teas are sure to zap any morning drowsiness—and set your metabolism up for a hotter burn. In a study published in the journal Food Science and Biotechnology, researchers found that caffeine revs the sympathetic nervous system and increases lipolysis. Look for teas made from this caffeine-containing fruit; if you want to skip the label reading, just grab a box of Celestial Seasonings Fast Lane, which clocks in at 110 milligrams of caffeine.
The leaner your muscles, the faster your metabolism. But if only a few muscles on your body are super-lean due to repeated exercises, you’re not going to get maximum results. Kimberly suggests engaging in activities that strengthen more than one muscle group at a time. “For example, instead of sitting and doing bicep curls, stand and do bicep curls while squatting,” she says. “Working multiple muscle groups simultaneously naturally increases caloric expenditure. On top of this, more muscle groups working translates into more muscle fibers created.” You’ll burn more calories and increase lean muscle mass.
Think of every bean as a little weight-loss pill. One study found that people who ate a ¾ cup of beans daily weighed 6.6 pounds less than those who didn’t—despite bean eaters consuming, on average, 199 calories more per day. The magic is in the perfect combination of protein and fiber: Studies show that those who eat the most fiber gain the least weight over time and that eating fiber can rev your fat burn by as much as 30 percent. Aim for about 25 grams of fiber a day—the amount present in about three servings each of fruits and vegetables.
While drinking in moderation every so often won’t do too much harm to your waistline, making it a habit can slow down your metabolic rate. Why? When your body has a cocktail to break down, it takes precedence over any food that you’ve already eaten that’s waiting to be digested. This slows down the entire metabolic process. On the occasions that you decided to indulge, stick to low-calorie drinks. Alternate your alcohol with water to slow your pace, and cut yourself off after two drinks. Avoid ordering high-cal bar food like fries and burgers. An important note: Wine in moderation can have numerous benefits, including weight loss!
Tea, often used in many diet fads is scientifically proven to boost your metabolism while trimming your waist line. In a study published in the Journal of Medicine Investigation, researchers tested the effects of oolong tea on energy metabolism in 11 healthy Japanese females who either consumed water, oolong tea, or green tea. In comparison to water and green tea, oolong tea increased energy metabolism by 10 percent which increases the overall metabolic rate. The polyphenols — compounds found in tea — are said to be responsible for the enhancement of the females' metabolism.

After a week or two, your body will adjust to a more active lifestyle. That's when it's time to add workouts that increase metabolism. If you are healthy enough for vigorous exercise add one HIIT or Tabata session per week. Then gradually add one or two more. You can also add up to 3 strength training workouts per week to increase your metabolism with lean muscle mass. 
Some things, though, aren’t that simple. For instance, someone with a higher metabolism burns more calories at rest than someone with a lower metabolism, and can therefore get away with eating more food—even junk food. But a high metabolism isn’t a privilege reserved for a select few lucky enough to be born with it. You can raise yours and reap the benefits, too.
So how many calories should you consume? Depending on your level of activity, you can safely lose anywhere from half a pound to two pounds a week if you multiply your current weight by 11, says Applegate. (For example, if you're 120 pounds, aim for around 1,320 calories a day.) Unless you're less than five feet tall, don't let your daily calories dip below 1,200. "Research shows that women who consume less than this amount see their resting metabolic rate plummet by as much as 45 percent," notes Dale Huff, R.D., a St. Louis nutritionist.
Spicy foods have natural chemicals that can kick your metabolism into a higher gear. Cooking foods with a tablespoon of chopped red or green chili pepper can boost your metabolic rate. The effect is probably temporary, but if you eat spicy foods often, the benefits may add up. For a quick boost, spice up pasta dishes, chili, and stews with red pepper flakes.
Here's welcome news: You may have inherited your mom's slow-mo metabolism, but you’re not stuck with it. New research shows you can trick your body into burning calories more efficiently, especially if you hit the gym. By strength-training just a couple of times a week, for example, you’ll reverse 50% of the seemingly inevitable metabolism slow-down that comes with age, says Gary Hunter, PhD, a professor of human studies at the University of Alabama at Birmingham. So take control of your metabolism by making these boosters part of your routine—and (finally) stop sweating every cookie.
As the endocrine system controls the rate and direction of metabolism, what you consume and your level of physical activity will overall influence the speed of your metabolism and how much you weight you gain. The belief that your metabolism is to blame for increased fat is not correct. Eating more calories than you can burn is the primary cause. The best way to control how many calories you burn is through your level of physical activity, according to the Mayo Clinic. What appears to be a faster metabolism in others is more often a more active lifestyle, that leads to weight loss or maintaining a steady weight.
