Again, black and white thinking doesn't solve the problem. It just alienates people, and sometimes worse.
It is an objective fact that caloric surpluses and deficits are fundamental to manipulating bodyweight.
Any solution will be about getting people to maintain a surplus or deficit long enough to reach their goal weight.
There are many ways to communicate that to people, but pretending or trying to convince others that it isn't true is factually incorrect and literally counter-productive to their goals.
But it's ok. I loose weight by exercising and eating less. Like the climate change denialists, you can lead people down the dark path if you like.
Me I'll stick with me 3kg loss of weight every month and celebrate.
It's missing the forest for the chlorophyll.
