I’m told that 5% of dieters keep off the weight long-term. (Interestingly, this is also the success rate of quitting smoking.) Unless 5% of people who don’t try to lose weight also lose weight and keep it off, sounds like diets work, just not very well.

You would have to compare to how many non-dieters lose weight and keep it off long-term.
Is there a standard abbreviation for “I would like to see this testable prediction tested”?
5% is a very small effect. Not only would you want to see the control group, but you’d need a huge sample size to get anywhere.
