I see a multitude of cases where jumping out of the plane without parachute won't kill me. From the plane being on the ground, to me being equipped with anything other than a parachute that lets me fly enough, jumping from a plane to another etc.
And I'm not just being facetious, that's exactly the issue we have with pathology related diets, there's a myriad of variables and circumstances to take into account, which makes vague common sense dogmas innaplicable.
Think about it: we have very thorough studies of people dying from hitting static surfaces at high velocity. Why don't we have the same level of evidence for long term obesity treatment if it's a obvious as you say it is ?
> we have very thorough studies of people dying from hitting static surfaces at high velocity
What are those studies?
Yes we do, because it works. Exercise burns more calories. Diet limits your calorie intake.
If you rebound into not doing exercise and overeating, that's on you.
