Unlike most of the other women in today's list, Mary Helen Bowers is not a professional weightlifter, bodybuilder or even a fitness instructor. Mary is a ballerina, as you can see in the above photo - that's why her figure and muscle mass are much smaller than the other featured girls. Ballerinas have to keep a low weight in order to be as nimble and agile as possible.
She explains her diet, "For breakfast, I will have coffee and 1) slow-cooked oats with some raw nuts and fresh fruit. In the winter it tends to be a lot of citrus, especially grapefruit. I also eat an 2) apple every day, because they are so easy, fast and full of fiber. For lunch, I usually try to have a 3) large salad with a ton of fresh greens, veggies and a side of grilled chicken, salmon or steak and some wheat bread."
