Cardio improves definition and burns the fat that covers your muscles, especially belly fat. Combining regular aerobic exercise with strength training will give you the slimming effect you've been going for. After all, toning without cardio is like building a house on a weak foundation. Blast calories with these 20-minute cardio workouts from celebrity trainer Jackie Warner.
"Stay away from processed, high sugar, junk food, even fruit juice," says Michael Mountain, author of Ultimate Fat Loss Solution. Stick to protein, which increases metabolism by 30 percent for up to 12 hours, whereas carbs and fat increase metabolism by 4 percent for less than one hour. And don't forget fiber—it binds with metabolized fat and removes it from the body.
When it comes to the best workouts for weight loss, neither weights nor cardio can completely move the needle on their own. Interval training is the best way to shed pounds, increase your metabolism, improve your cholesterol profile, and improve insulin sensitivity. At the gym, sign up for a HIIT class, or turn your favorite aerobic exercise, (running, biking, even walking) into an interval workout by adding periods of intense speed (start with 30 to 60 seconds) followed by periods of rest (normal speed) for the same amount of time. Do this six to 10 times to complete a fat-slashing workout. As you get better, slowly increase the amount of time of increased intensity.
Muscles are fat-burning furnaces, so be sure to do enough resistance training to build and maintain them (these fast workouts tone your whole body in 30 minutes), and follow your workout with a healthy meal or snack that contains protein, carbohydrates and fat. Building new muscle raises your Resting Metabolic Rate (RMR) so you'll burn more calories every day.
Some ingredients in energy drinks can give your metabolism a boost. They're full of caffeine, which increases the amount of energy your body uses. They sometimes have taurine, an amino acid. Taurine can speed up your metabolism and may help burn fat. But using these drinks can cause problems like high blood pressure, anxiety, and sleep issues for some people. The American Academy of Pediatrics doesn’t recommend them for kids and teens.
Skimping on sleep can derail your metabolism. In a study at the University of Chicago, people who got four hours of sleep or less a night had more difficulty processing carbohydrates. "When you're exhausted, your body lacks the energy to do its normal day-to-day functions, which include burning calories, so your metabolism is automatically lowered," explains Peeke.
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.
