there is a lot of great healthy food, people just don't realize it because a lot of health food is crap. eating healthy but tasty requires more work than eating unhealthy, because most of the unhealthy crap you eat (burgers, fries, potato chips) is just fried and salted into oblivion. after you get rid of the crap, you actually have to develop flavors.
chicken breasts and lean meat are both healthy and can be delicious. fish is also very healthy. replace cooking oil with olive oil. stop drinking soda, replace it with water or low-sugar juices.
a grilled chicken salad can be either crappy or incredibly tasty. it's all about how you prepare it.
