A couple of points: 1) The low-carb hypothesis is that there is a fundamental physiological reason that highly refined carbs cause weight gain. It goes something like this: highly refined carbs get stored by your body as fat. Because they get stored as far, they are unavailable to be used for energy. Because they are unavailable to be used as energy, you get hungry (this is your body signaling that it needs energy). So you eat more carbs. Wash, rinse, repeat. Do you have a specific claim as to how this hypothesis is incorrect? 2) It is a complete non-issue that it's hard to compete in long distance running races while on a low-carb diet, especially for people who are obese. Running has an incredibly high injury rate (on the order of 20-90% of runners get injured per year, Google "running injury rate"). It's about the worst way imaginable for an obese person to be active.
