Being overweight because you eat too much is one of the most needlessly self-destructive things we can ever do to our own bodies, but weight that's caused by excess eating is also the easiest weight to shift. All you need to do is cut down to the right amount of calorie intake for your height, and the rest will take care of itself. In circumstances like this, weight loss can be rapid, and dramatic.
Even taking that into account, the 167-pound weight loss of this woman is remarkable - as is the fact that she managed to do it all within one year! As we've seen before, losing weight around the face can really help to draw attention to someone's eyes, and hers are sparkling now. That's the happy smile of someone who knows that they've gone head to head with their own weight - and won!
