Not a good mindset you have there Zamzow, that you can out run or out exercise a poor diet or that you can't override genetic inclinations.
Genetics might determine frame size and the tendency for some to either be noticeably slender or stocky (curvy for females), but a proper more natural diet along with daily physical activity (intentional or incidental) play the most important role in determining size and overall health. And time. Whatever you do, you have to give it lots of time.
We might all come in slightly different shapes and sizes, but a little education and self-discipline will get you where you need to be. And I find that the more education you have on living a healthy lifestyle, the less self-discipline you need, because one doesn't have to live on 'rabbit food' or be a 'gym rat' to make slow steady progress and maintain it.
