"There are certain key nutrients that make a huge difference in not just how healthy you feel on the inside, but how healthy you look on the outside," says Tara Gidus, team dietitian for the Orlando Magic and spokesperson for the American Dietetic Association. Check out her "No-Effort Guide" to looking great this week on AOL Health. One tip? Do this simple detox: Drink enough water. This liquid flushes out toxins and transports oxygen to your cells, which can not only boost skin clarity and reduce the appearance of wrinkles, but water also affects how defined your muscles look and how much power they provide you when you need them for other purposes -- say working out. So what are you waiting for? Start looking better today.

I told you the other day why I exercise. It went like this.

• It makes up for the extra calories I eat.
• It fuels my day with energy -- I'm an AM exerciser.
• It motivates me.
• It makes me feel accomplished.
• It makes me feel healthy.
• It makes me feel strong.
• It helps me maintain my weight.
• It's give me time alone.
• It allows me to role model a behavior I hope my kids will embrace.
• It keeps cancer away -- research says five hours of weekly strenuous exercise helps prevent breast cancer recurrence.
  
  

Then I asked: Why do you exercise? Here's what a few of you said.

We all know that America has a weight problem. Most people seem to think it's because we eat too much, which is certainly true; but it's also because we move too little!

Our world, our environment, has changed dramatically in the last 25 years and physical activity has been engineered out of our lives. We have remote controls, garage door openers, robotic lawn mowers, and electric windows. We also have drive-in banks, restaurants, dry cleaners, pharmacies and believe it or not, near where I live, there's a convenient store that has a drive-up window where you can purchase lottery tickets. These days you can stay seated for almost anything. And, when I was a kid and got into trouble, I had to come inside. Now when a kid gets in trouble parents cut off video games, phones and TV (in our house, this is called 'electronic lock-down') and send the kids outside for punishment . The truth is we need to stop avoiding physical activity, instead we need to embrace it.

The human body has about 60 trillion cells and every single one of them is positively impacted when we move -- so if you want to lose weight, improve your health, and feel better, then eat a little bit less and move a whole lot more!
