It's all about environment. I don't know about you, but in college I quickly noticed that if I hung out with the hard workers I would get great grades and do all my work on time, and if I hung out with slackers I would just play video games all day.
Put the unfittest, unhealthiest person you know in a house with crazy healthy and fit people for a few months, and you'll notice drastic changes in their habits and behaviors. The opposite is true - put a healthy person in a house where their roommates eat pizzas and watch TV all the time, and they'll quickly get to their level.
On one hand it's depressing (if all your friends and family follow the same patterns you'll have a hard time breaking out of it), but on the other hand it's empowering: you can modify your environment to encourage healthier habits (if all you have in your fridge is healthy food, you won't be snacking on Cheesy Poofs when you're hungry at 4pm).
