No professional would recommend a crash diet for a typical person, so I'm not sure what your point is. You're right; moderate deficit is best, but I don't see anyone recommending anything else and you implied that calorie accounting in general doesn't work, which is nonsense. Also, one big issue yo-yo dieters encounter is that, once they reach their goal, they go back to their old habits. You can eat more once you hit your goal, but you can _never_ go back to your old, unhealthy diet if you want to maintain what you accomplished.
