1. Play footsie… with yourself

Are you a toe-tapper? A pencil twirler? A leg shaker? Don’t stifle it—all these little movements can bolster your metabolism.
Fidgeters can burn up to 500 calories a day without even thinking about it.
That adds up to losing nearly half a kilo a week.
Just make sure your fidget isn’t humming or otherwise making noise, as that may make your co-workers kill you, which would not be good for your metabolism at all!
Not a fidgeter? Take a look at these four simple lifestyle hacks that help you burn fat fast.
2. Down a cup or two of coffee

Caffeine is a central nervous system stimulant and your daily java can rev your metabolism five to eight percent, helping you burn an extra 98 to 174 calories a day, says Julie Lohre, a certified personal trainer, nutrition specialist, and American Ninja Warrior.
Drinking your cup of coffee before your workout can also help you stay more focused on your exercise, which can also boost your metabolism, she adds.
Everyone prefers coffee differently. Some people take it with cream, some with sugar. But when it comes to the brew, there are scientific best practices.

Few things are as coveted as good sleep. Drawing upon recent scientific research, these tips will help guarantee you wakeful days and blissful nights.
