6 WAYS TO BOOST YOUR METABOLISM

If anyone has ever told you that you’re stuck with your slow metabolism—they’re wrong.

In fact, new research suggests that while energy expenditure is partly genetic, you can trick your body into burning calories more efficiently. Take your calorie-burning and weight loss potential to the next level with these 6 surprising metabolism hacks, inspired by new research in the New York Times bestsellerZero Belly Diet:

It’s no joke: genuine laughter may cause a 10–20 percent increase in basal energy expenditure and resting heart-rate, according to a study published in theInternational Journal of Obesity. That means a 10-15 minute giggle fest could burn up 40 to 170 calories. Let me hear you lol!

A striking new study published in the journal Diabetes suggests that simply turning on the AC may subtly transform a person’s stores of brown fat—“good” fat, stimulated by cold temperatures, that serves to keep us warm by burning through “bad” fat stores. Participants spent a few weeks sleeping in bedrooms with varying temperatures: a neutral 75 degrees, a cool 66 degrees, and a balmy 81 degrees. After four weeks of sleeping at 66 degrees, the men had almost doubled their volumes of brown fat. Cool! (In fact, your bedroom is an often-overlooked weight loss booster.

It’s well reported that fiery capsaicin (think: hot sauce, cayenne, chilies) can rev up the metabolism, but study findings presented at the Experimental Biology meeting in Anaheim, California, showed similar weight loss potential in dihydrocapsiate (DCT), the non-spicy cousin of hot peppers. Participants who ate the most DCT experienced a metabolic boost that was nearly double the placebo group! Bottom line: pile on the poblanos! (Craving something spicy while you’re out?

Weight loss doesn’t get easier than this: Simply drinking more water may increase the rate at which healthy people burn calories, according to a study inThe Journal of Clinical Endocrinology and Metabolism. After drinking approximately 17 ounces of water (about 2 tall glasses), participants’ metabolic rates increased by 30 percent. The researchers estimate that increasing water intake by 1.5 liters a day (about 6 cups) would burn an extra 17,400 calories over the course of the year—a weight loss of approximately five pounds!

Add mustard to your meal, and feel the burn—literally! Scientists at England’s Oxford Polytechnic Institute found that by eating 1 tsp of mustard (about 5 calories) can boost the metabolism by up to 25 percent for several hours after eating. The benefits, researchers say, may be attributed to capsaicin and allyl isothiocyanates, phytochemicals that give the mustard its characteristic flavor.

Forget slogging on the treadmill for hours, research printed in the journalPhysiological Reports showed that people who did five 30-second bursts of max-effort cycling, followed by 4 minutes of rest, burned 200 extra calories that day. That’s just 2.5 minutes of work for a resting metabolism boost that will last 24-48 hours!
