No, the energy you use to speed up will negate any einstinian effect

If you are an Olympian and can run 100m in under 10 seconds, your body weight would not increase by even a fraction on the best scale you can find. Even if you could run 10 million times as fast (1/3 the speed of light) your body weight would not increase significantly. And even if you could run almost as fast as light, your weight would increase, not your waist!
The Lorentz equations that talk about the increase of mass at higher speeds only work if you move very close to the speed of light. Other problems would occur before you notice this on running (if it were possible), notably you'd literally vanish consuming all your body mass and transforming it into running energy. This of course only if you could keep increasing your speed long enough to attain the required speed. Using the same example of the Olympian, you'd have to increase your speed as he does during the first 60-80 yards, but not for the 5-6 seconds it takes him but for almost one straight year!

What a great excuse for not exercising! But, no. Unless you are able to run at relativistic speeds (like the Flash) you do not have to worry about becoming more massive. He has the Speed Force, so he can go that fast without having problems breathing or seeing where he is going, or needing to consume infinite quantities of food. We don’t. So, at non-relativistic speeds, the faster you run, the more calories you will burn and the more weight you will lose. Nice try, though.

No. If you carried a mirror with you as you run, you would look the same (you are at rest in your own frame). On the other hand, someone else who is observing you run faster will see you actually get thinner (length contraction). This is why the theory is called Relativity. It all depends on relative motion. To someone in your rest frame (running along side you) you will appear unchanged, but to an observer standing by you will appear to be shortened in the direction of travel.

If you are eating Einstein bagels quicker the faster you run, Einstein would agree you will get fatter.

You wont get fatter (if you are not considering length elongation) but only your mass would increase and that to by negligible amount. Its not that if you 40 kg mass and you start running your mass would become 41 kg. To have any significant changes in your mass you need to run at speeds which are comparable to speed of light.

A colourful distortion of Einsteins General theory of relativity.
Try it and see!

No, I think you`ll get longer the faster you run????

No. Your belt size will remain the same but your mass will increase.

How did you work that one out?
