Beyond the fact that just telling people to do so is ineffective, my experience is that most people have a very poor idea of what is and isn't calorie dense (I've been there!), how many calories they consume in snacks, or how to eat in a way that leave you feeling full without gobbling down calories.

I've been around people who made legitimate good-faith efforts to diet and eat "healthy", but have no idea that "just a bowl of rice to go with it" and "I need my afternoon milk tea" and maybe another snack are like 500+ extra calories each day, that hardly even leave you full.
