I disagree. Moderation works, if the definition of moderation adjusts with changes in your body, activity level, and age. My definition of moderation is different at 35 than it was at 25, and will be at 45.
It also depends on what your goals are - is it weight loss? Training for an athletic event? Improving gut health? Working to reverse high cholesterol, BP, or diabetes?
I believe diet and exercise is an incredibly personal choice and there is no one size fits all plan or approach. Everyone’s situation and motivation is different. Every step someone takes to improving their health is a good one, even if it doesn’t line up with what your point of view may be.
