Move abroad. Get an italian or greek or spanish partner. You’ll have no option but to get into healthier eating habits.

Whislt the above suggestion might be a bit tongue in cheek, as with any lifestyle habit, whether it be drugs, drink, exercise or eating, your setting and company can make all the difference.

Maybe join a cookery class. Not only will you learn how to cook things that are tastier than snacky food, you’ll make friends with people that will likely have a positive attitude towards eating in general and that will likely rub off on you.
