 So when I first lost my leg, it was absolutely mind blowing to me how hungry I was every second of every day, especially when I started using my prosthetic, learning how to walk again. No joke, I would like have a full meal of steak and potatoes and still be ravenous, which didn't compute because you lose a part of your body, you think your body probably needs less energy to process. False, because your body is using so many muscles to balance, stabilize and compensate for the loss of a limb, if you lose your leg below your knee, you are expending about 20% more energy than if you were walking on two meat legs. Mind blowing, I never would have thought that. And especially as an amputee, as the gift of being pretty mobile and pretty active, I am hungry all of the time.
