You know you should exercise and eat healthfully to keep your weight in check. The thing is, research suggest that when people devote time to one healthy habit, they spend less time on the other . So which is more important if you’re worried about your waistline: your workout or your diet? Turns out, people who think that diet is the most important factor in weight control tend to have a lower body mass index (BMI) than those who believe that exercise is the key, according to six new studies published in the journal Psychological Science.
BMI (Body Mass Index) English Units: BMI = Weight (lb) / (Height (in) x Height (in)) x 703
On the flip side, if you believe that eating a healthy diet is the best way to maintain your weight, you might worry less about exercise—but closely watch what you eat. And that’s smart, especially because most people grossly underestimate the amount of calories they consume, says McFerran.
The problem: Many people think they can work off extra pounds—but there’s a ton of scientific evidence to support the fact that changing your diet is a more effective way to drop weight, says McFerran. “If we eat a 3000-calorie lunch, nearly no one has enough free time in the rest of the day to exercise it off,” he says.
Luckily, McFerran’s best advice for weight control doesn’t take much time: Steer clear of foods that are high in calories, and trade large plates and bowls for smaller ones to ensure you fill them with more restrained portions.
That said, you should probably hold onto your gym membership, too. Although it’s tough to slim down with exercise alone, staying active does help with weight control—and it’s absolutely crucial for your health, says Keri Glassman, RD, a Women’s Health weight loss expert. Not only does exercise produce endorphins that increase your metabolic rate and motivate you to eat better—it also supports heart health, strengthens your bones, helps you sleep, decreases stress, and boosts mental health. All awesome reasons to hit the gym when you can!
