If you couldn’t let anything cross your lips from 5:00 p.m. to 9:00 a.m., but you were allowed to eat anything you wanted for eight hours a day and still lose weight, would you try it? That’s the apparent bottom line of a rat study published in the journal Cell Metabolism, which recently stirred up the weight loss pot.

Top 50 Summer Diet Foods for Weight Loss

Scientists put groups of mice on different diet regimens for 100 days. One group of rodents ate healthy food while animals in two of the groups chowed down on high-fat, high-calorie feed. Half of the junk food eaters were allowed to munch whenever they wanted to while the others only had access to feed for the eight hours they were most active. The conclusion: even though they ate a fatty diet, the mice who were forced to fast for 16 hours were almost as lean as those who ate the healthy fare. Interestingly, the round the clock junk food eaters became obese and developed health problems, even though they consumed about the same amount of fat and calories as the time-restricted junk food fed mice.

When I started losing weight, I often looked at women who were thinner than I was and thought, "Wow, her life must be so easy." I knew that once I got to my goal weight, I'd feel awesome, and healthy living would be just as easy for me as it was for all the "I can eat whatever I want and not gain weight" women around me.

11 Ways to Rev Up Your Metabolism

Now that I've lost 75 pounds, I can say that I do feel awesome . . . but I can't say that a healthy lifestyle comes easy. Weight maintenance isn't as simple as I expected. While being at my goal weight has its perks, I have to admit: I failed to appreciate some of the great benefits I enjoyed along the way. If I did it all over again, then here's what I'd do differently:

You've always heard that when it comes to building muscle mass, heavy weights are preferred over lighter weights. But a new study published in the Journal of Applied Physiology has found that isn't always the case. In fact, you can build just as much muscle by lifting lighter weights. If you do it right...

10 Health and Fitness Myths You Still Believe

The key is working the muscle to total failure or exhaustion, says Michele S. Olson, professor of exercise science at the Human Performance Laboratory of Auburn University Montgomery and the star of the workout DVD Perfect Legs, Glutes and Abs.

8 Reasons Why You Should Lift Heavier Weights

"Failure, in this sense, is a success," Olson says. "If you work your muscles, on each set, until you cannot execute another repetition with appropriate form, the heaviness of the weight becomes less important."

The weather is getting nice and you may have been bitten by the "run bug." To make the transition from indoor runs to the great outdoors seamless and safe, I compiled a list of my top five tricks to get the most out of your outdoor run. Whether you have had some success running on the treadmill, or you are completely new to outdoor running, there are two crucial factors that you must understand.

25 Most Deceiving Exercises (They Tone More Than You Think).

First, let's talk about a little guy named Newton. See, Newton has this law that states that for every action, there is an equal and opposite reaction. Are you with me so far? Good. Well, with runners, the concern is what we run on. The harder the surface the greater the ground reaction force, which is basically the force exerted by the ground back onto the body (in this case, our little legs) that are in contact with it, is. To simplify this, surfaces like concrete and pavement will cause a greater reaction back into our joints and legs than an energy absorbing treadmill. This not only makes us work harder, but will tire us out faster and cause greater stress on our joints.

Second, the treadmill is a flat belt that provides consistency with each step. There are no stones, traffic, or inclement weather activity that would cause you to be off balance or have to change your gait. Running outdoors forces the body to make constant small adjustments.  That said, here is what’s going to make your outdoor run a successful one.

Ah, that infamous area along the back of your arms, the nemesis of so many women. How do you tackle the jiggle? First, I want to tell you what not to do, as people are often tempted to take the wrong course of action. And that is the concept of spot reducing, or lowering fat stores in one specific area of the body. It is essentially impossible to accomplish and should not be a part of your fitness regimen. Fighting arm flab requires more than just spot treatment!

In order to tone the backs of your arms, which is where your tricep muscles are, you have to remember this: specific exercises to increase your lean muscle mass will get you results, but you must also decrease your fat intake without risking too much muscle loss. (Sound familiar? Have you managed to lose fat, but still carry some extra bulk around the tricep?) So, to lose the wiggle and jiggle, be sure to eat a healthy balanced diet with proper nutrients; get at least six to eight hours of sleep so that your body can repair, recover, and build muscle; and consistently maintain your exercise program. And be sure to incorporate these five flab-fighting exercises into your workout routine.

We're all familiar with the things that signal spring’s arrival: extra hours of daylight, budding flowers, and Cadbury Crème Eggs on display at every supermarket and drugstore in America. It’s easy to justify grabbing one (or two) of the seasonal treats on your way to the checkout (They’re only available for a few weeks out of the year). But have you ever wondered what’s inside the chocolate shell? You'll be happy to learn that there is actual egg in Cadbury Crème Eggs, but the rest might (or might not) surprise you.

Q: Could my post-workout snack be making me fat? I've read that chocolate milk is a great post-workout drink, but is that still true if I just took a beginning Zumba class (or did a similar low-intensity workout)?

20 Foods That Can Ruin Your Workout

A: No, your post-workout snack is not making you fat. In fact, quite the opposite. The holy grail of nutrition is to be able to preferentially send the nutrients in your food toward your muscles for energy and repair and not to your fat cells. Exercise is the one thing that can do this. Exercise causes your muscles' cells to actively pull sugar out of your bloodstream and into your muscles with much more fervor than any other time of day.

Yes, pink slime is gross. No one wants to think about anything being in their burger except actual meat. But the huge controversy may be about more than just pink slime.

The biggest concern with pink slime is that we're buying (or eating) a product and we don't exactly know what it's made of, says Prescott Frost, a champion of sustainable agriculture and a rancher and producer of organic, 100 percent grass-fed beef.

"I’d have to say that the controversy over pink slime is a reaction to corporate farming, and the reaction is a natural one to our concerns about corporate farming and big agriculture," Frost says. "Every day we become more and more aware of their effects on our daily lives, whether it is the food we eat, the environment we live in, or the way we treat our animals."
