This feels like a pretty uncharitable take, for a start sugar is pretty addictive and reducing / cutting it out of your life if you're used to having lots of it isn't easy. Secondly I vaguely recall the shift as a university student routinely eating take away to cooking for myself, it's not a trivial step, you have to pickup habits around shopping, meal planning and cooking. There's a lot of steps someone who's not used to doing it can drop off on. So yes, I can believe that people both know what are healthier options, but have no idea how to actually practically execute them in their life. It is deeply unhelpful to give people advice that they can't action and then expect them to thank you for it.
