Question: Shortness of breath and obesity?

What makes you think he isn't being great this time? You're 40 pounds overweight, and he recommended weight loss - sounds appropriate to me. Your body uses air as part of the process of using the energy in food. The more energy you are trying to use at any given time, the more air you need (which is why you breathe harder when exercising). Your blood circulates oxygen and energy through your whole body - muscle, fat, everything. So when a person is overweight, the circulatory system has to cover more ground. But the heart and lungs aren't any larger, so their only option is to work harder. Being out of shape means your systems aren't as efficient as they could be. The combination of these two things is why you experience shortness of breath.
