Exercise won’t necessarily help you lose weight, but it will help you … – Los Angeles Times

Hoping to shimmy into those skinny jeans by adding an extra spin class to your workout routine or spending more time on the treadmill?

Sorry, say experts, youre out of luck. Exercise, while enormously beneficial for maintaining a healthy weight, doesnt tend to be effective for shedding pounds. The best way to trim the flab is to minimize the food on your plate.

You cannot outrun a bad diet, as an editorial in the British Journal of Sports Medicine put it.

Yes, exercise would work if you did enough of it its just so much easier to eat less, says James Hill , professor of pediatrics and medicine at the University of Colorado Anschutz Medical Campus in Aurora. It takes mere seconds to scarf a 200-calorie candy bar, but 40 minutes of walking to burn that off. And with weight loss, youre not just trying to break even youre aiming for a calorie deficit.

Some people about 15% of us may even find that exercise makes them much hungrier, countering weight loss goals, says Dr. Tim Church , a professor of preventive medicine at the Pennington Biomedical Research Center in Baton Rouge, La.

But exercise does playa key role: It helps keep weight off once youve lost it. Since 1994, Hill has tracked more than 10,000 people in the National Weight Control Registry who shed an average of 66 pounds each and kept it off for more than five years. Only 9%of them maintain their weight without significant exercise so its possible, but its very rare, Hill says.

For one thing, its hard to cut food calories over the long term. Exercise, on the other hand, burns added calories. It also improves metabolism, including how the body manages blood sugar and appetite. Youre giving yourself a safety margin for those days when you eat a bit too much.

But dontoverestimate that margin, Church warns. Taking the stairs does not earn you a cheeseburger.

In addition to keeping you trim, exercise is good for the heart, the liver and other essential organs, studies show. It even helps the brain by alleviating depression and anxiety, and by warding off cognitive decline later in life.

You name it, exercise helps it, Church says.

Hill says those whove lost a lot of weight and dont want to regain it should exercise for70 minutes a day. (People who were never obese can get away with less yes, life is unfair.) That could include planned workouts like going to the gym, but also casual activities like walking around a mall or playing Pokemon Go.

Figure out what works for you, Church says.
