Nothing wrong with supporting others - I myself strayed into H&F in search of advice...
So apologies if my comments came across as mocking.
Weight is an important factor in how we feel and perform, etc. But I see it as an output, with several contributing factors as inputs, which have other factors contributing to them. So, in my ignorance, I imagine we focus on weight as we can easily measure it; whereas the underlying factors, which might be stress or boredom, or cultural norms, are harder to get at and address.
Which might explain why dieting does not work for everyone. It is a bit like balancing your bank account by not paying some bills - makes the numbers look right in the short term but does not solve the issue.
I do know in the rare moments I have felt fit, healthy and generally 'good,' I have not had to worry about my weight - it took care of itself.
