Ali Fedotowsky shows off her banging bikini body after her weight fluctuated while filming "The Bachelorette." The reality star packed on 10 pounds.

She told OK magazine, "I was always hungry. I didn't think much of it, but everyone noticed."

How did she get back into shape again? She went on a low-calorie, high protein diet and started running every day.  Weeks later she dropped some of the weight and is now showing the results!

If only it was that easy for the rest of us!
