Every time the New York Times publishes a health-related article, the comment section is filled with comments just like this: just self-congratulations without any useful takeaways for anyone else, and zero self-awareness that would enable them to realize, hey, not everyone is like me.
Whenever one feels tempted to utter “it’s all in your head”, my advice is to take a step back and reflect on how little I know about the circumstances of others, and then, you know, maybe just keep it to myself.
Behavioural patterns are heavily influenced by hormonal balance and as such, success-rates of different self-help strategies (diets, fasting, resistance and/or endurance training) are highly individual. This also extends to addictive behaviours.
"Hormon-typical" individuals have an easier time shaping their behavior because they don't face imbalances that complicate adherence. For them, sticking to a program is trivial. Combine that with lack of reflection, and many of these individuals delude themselves into thinking their success of following simple programs (which are simple in design, and only difficult in adherence) is somehow an accomplishment worthy of note. Low-empathy individuals, in particular, often interpret this as evidence of their own superiority, while dismissing others as mediocre.
So you see such comments a lot, because many people are "hormon-typical" and also low empathy. See any discussion about diet, fitness, Ozempic, etc.
