Q. Hello! I came across your trip reports from your Disney World vacation in June while searching the web for some advice on healthy eating at Disney. Very helpful posts -- thank you! Our family was there last summer and we are going back next week. However, since January I have lost around 55 lbs (with a few more pounds still to go). I wasn't that concerned about eating healthy last summer, but I am worried this summer that I will gain weight during vacation instead of maintaining or losing weight, as I am still trying to do. I know that Disney World is tons of walking (it's me, my husband, and our two boys, ages 7 and 5), but there is no nutrition/calorie information for any of the food from Disney's table or counter-service restaurants. The main way that I have lost weight is by counting calories and exercising. So I feel a little "lost" when it comes to what I will eat on vacation. Also, my husband and kids are fairly picky eaters and so we pretty much only eat at places that offer the standard "hamburgers, hot dogs, chicken nuggets, pizza", etc. Thanks for your trip report -- sounds like you and your family had a wonderful time at Disney World!!!

A. Hi Melody. Lucky you! I wish I were going back to Disney next week! Hopefully my answer will prove to be the simple reassurance you need to relax and enjoy the magic of Disney. Sweetie ... you've lost 55 pounds; you already know what you are doing! All I want you to do is to continue pursuing the same fabulous food you choose at home in Delaware. Disney has totally cleaned up its act in the healthy food department. I literally found healthier menu items at Disney's Magic Kingdom than I have ever found in my own home town!

Wellness programs are gaining popularity with employers (about 1/3 of companies in the U.S. now offer them) and for many, it's a real blessing, after all who wouldn't want a free gym membership sitting out there that they can use or not, or free health screenings and flu shots available right on the job site?

You've probably heard that the brain consists of two distinct lobes -- the right and the left. The right is responsible for imagination, feelings and creativity, while the left is responsible for logic, details and facts. Want to know which lobe is dominant for you? Go to this link, look at the picture of the dancer and focus on which way she is turning. Is it clockwise? Or counter-clockwise?

If clockwise is your answer, you use your right brain more often. If you saw her moving in the other direction, you use your left. If you look really hard and focus on the dancer, you can see that she changes direction.

For me, she was turning counter-clockwise, which means my left lobe is more dominant -- therefore I'm more logical. What about you?

Are you surprised at all when I tell you American obesity rates are soaring? Probably not. I wasn't when my husband told me about this weighty article he'd read. It revealed that not one state showed a decline in obesity during the year 2006. Mississippi was the first state to crack the 30 percent barrier for obese adults. West Virginia and Alabama were just slightly behind. Colorado was the leanest state with a 17.6 percent rate. This year's report, looking at overweight children for the first time, has the District of Columbia topping the charts with heavy kids and Utah boasting the lowest rates for little ones.

Obesity is becoming an epidemic. And we need to treat it as an emergency. First step: determine where you stand. My hubby located this body mass index (BMI) calculator. I share it with you today so you can chart your own measurement. Just enter your height and weight and then calculate your BMI with one click of your mouse. If you come up with the number 30 or higher, you fit the definition of obese. If you find yourself in this predicament, you're in the right place. That's Fit offers an abundance of health and fitness tricks that can help you whittle away at your digits. If you are below the 30 mark, pat yourself on the back. And keep on truckin' in the direction of health, fitness, and wellness.

There's just one way to fix our nation's obesity problem -- plain old hard work. Each and every one of us must eat right, exercise right, and minimize our health risks. Only then can we watch our obesity statistics, like our BMIs, melt away to more perfect numbers.

Researchers have found a link between individuals who are strongly right-handed (meaning they rarely if ever use their non-dominant hand to lead tasks) and distorted body image/eating disorders. Experts say it seems to have something to do with the fact that the brain processes body image mostly in the right hemisphere and right-handed people often have "decreased access" to that entire right side. No definitive word in the article on how this may help with treatment.

I don't like the idea of "decreased access" to any area of my brain (I need every cell I have!), and aren't the majority of us right-handed? How unfortunate.

Choosing the right sneaker is one of the most important components of surviving a great workout without any injuries. Just as a mouthpiece is vital to a boxer, proper footwear is important to you. I've seen folks running in basketball shoes and doing dance aerobics in running shoes. Both cases are an injury waiting to happen.

Nowadays, we walk into a shoe store and see a zillion different shoe types: runners, cross trainers, cleats, high tops, low tops, all terrain, etc. Why so many? We didn't used to have so many options. Sneakers were sneakers and that was that. Well, research and technology is your answer. Now that we know better, we do better. Each shoe is now specifically designed to provide support in places where certain activities cause the most shock. I'm listing a few examples, and before you read the supporting text. Think about what each athlete's feet and ankles endure.

Runners. Every time a runner takes a step, three times his/her body weight is impacting down on each foot. That is why there are often gigantic air pockets on the bottom of each shoe. Running shoes are created so that both your heel and forefoot are extremely supported with padding. The bottom tread is rough to grab the road and help prevent slipping. This shoe is light so the weight of each shoe doesn't hinder the users performance. Runners are normally only moving forward, so lateral ankle support of a high top is unnecessary.
