Men's Fitness. Supplements: What you need now! (May 2008): You try to eat healthy, but there are still those splurges on nachos, beer and pizza. (And that's just the short list of your cheat foods.) So you're likely nowhere close to getting all the nutrients you need each day. You're not alone. Who really eats nine servings of fruits and veggies every day? That's where a few well-chosen capsules can help.

Oxygen. Surprising fat traps (Winter 2010): It's a no-brainer that milk shakes, margaritas and M&Ms can make you pack on the pounds. Yet fat traps aren't always that obvious. In fact, you could be indulging in them and not even know it. Here are five diet offenders that could be adding to your bottom line.

Prevention. Lose the last 10 pounds (Oct 2008): You've cleaned up your diet, sweated off countless calories, and watched pounds melt away. But now the scale has come to a screeching halt. What gives? It's an unfortunate law of weight loss: The last 10 pounds are harder to shed than the first 30. That's because the slimmer you become, the fewer calories you burn just going about your day, explains Madelyn Fernstrom, PhD, founding director of the Weight Management Center at the University of Pittsburgh Medical Center and author of The Runner's Diet. For every pound you lose, your metabolism slows by up to 20 calories a day. But we do have some good news: Easy tweaks to the good habits you've already established can push you past your plateau and help you reach your final weight loss goal.

Reader's Digest's Walk It Off. Eat this, burn fat! (Spring 2010): We've all been there: Staring at a snack pack of Chips Ahoy and knowing we should eat the fat-free yogurt in the fridge instead. Same number of calories, though, so what's the difference, right? Surprisingly, a ton, especially if you're hoping to KO some fat from your frame. While there's no magic bullet for weight loss, the following foods and beverages naturally increase your body's fat-burning potential.

Real Simple. Food labels, decoded (March 2008): You can't judge a food by its cover, especially when product packaging trumpets some pretty confusing claims (low in this, free of that) and each label implies that its package's contents are healthier than another's. Some statements are based on sound science, but others carry little weight and even stretch the truth to lure you into buying. To help you make the wisest choices, Real Simple decoded common label terms. Read this and reap the benefits of a healthy diet.

Runner's World. Running on D (Dec 2009): Deena Kastor went to the 2008 Beijing Olympics full of hope and expectations. But barely three miles into the race, the American marathon record holder fractured a bone in her foot. A blood test soon after revealed a surprising possible culprit: vitamin D deficiency. Although Kastor's body had adequate amounts of bone-building calcium, she couldn't fully absorb the mineral because her vitamin D levels were low. "I wasn't aware of the serious consequences of low vitamin D," she says now.

Women's Health. Never have a pig-out again (April 2009): You sail through Super Bowl parties every year without dipping a single chip and survive the annual Girl Scout cookie blitz. So why does one lousy night with your boyfriend land you elbow-deep in a tub of mac'n cheese? Maybe because a dieter's worst enemy isn't temptation: it's really a foul mood.
