People seem to desperately want some trick to losing weight that isn’t “eat less food.” It won’t be forthcoming. You can’t trick your body into losing weight. We are adapted to scarcity, but food is not scarce.
"good advice" - Advice that actually works, and makes the person like you more
"bad advice" - Advice that doesn't help the person and makes the person like you less.
"Eat less food" would fall in the latter category, pretty obviously.

"Everybody should have infinite self control" is an obscenely naive starting point that erases the whole practical problem. The practical problem is "What habits require the minimum amount of self-control/unpleasantness to get the results I desire"?
If I were asked, i’d say that all diets that produce a calorie deficit are similarly effective and to try different things until you hit on the plan you can see yourself following for the rest of your life (at maintenance calories). Lots of people lose weight, maintaining is the biggest challenge.
