Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.

There was a time when food was just food. Humans lived off the land, eating some plants, the animals in the area and fruit, seeds and nuts when they were available. Today, the vast majority of “food” found in the grocery store are highly processed products created through modifying starch, or carbohydrate, in ways we’ve not seen in most of the history of the human race. Because these foods are the dominant foods in the places we buy our groceries, it takes a little thought before selecting an item. If meats, fish, poultry, produce, dairy, nuts and seeds were all the store sold, it would be easy to make your choices.

“I was borderline diabetic and my mother even suggested gastric bypass surgery, so I decided to try Atkins and pursue a low-carb lifestyle with the goal of coming back to school looking completely different. I reduced total net carbs and removed sugar from my diet. I also took advantage of the outdoor activities Lynchburg has to offer. In September my students didn’t even recognize me! Seeing the weight fall off, I began working out with a trainer at Planet Fitness, ran my first 5K race in Lynchburg’s Turkey Trot, and started walking with my children on the trails of Blackwater Creek. My proudest accomplishment, though, is that I inspired my daughter to start losing weight—she’s lost 50 pounds and counting.”
Gina Harney started The Fitnessista after she’d already lost 40 pounds. At the time, she was in maintenance mode in Georgia where, as she explains it, “healthy options were pretty scarce.” The blog was her way of chronicling how she sought out those healthy choices and often created them for herself. Today, Gina works as a certified personal trainer, group fitness instructor, and weight loss specialist. She loves sharing tips with her readers as they embark on their own journeys toward health.
