I think my life is a good balance of both--I believe in everything in moderation. There are definitely times when I live to eat. The best example of this is chocolate m&ms. I am well aware they give me little to no nutritional value. But in terms of my every day life, I can confidently say that with every chocolate m&m, my life gets a little better. So in these instances, I am living to eat. But in an equal amount of cases, I eat to live. For example, if I had no idea about nutrition, I would never drink cups of milk (I've hated the taste of milk from a young age). But because I know that without the calcium from milk my bones would deteriorate, I drink milk to live. Without a mix of both, I don't think I would be doing justice to my life as a whole.
A mixture of both. Especially in our society, where we constantly emphasize "body image" issues, I think its good to be conscious of what you're consuming, but not to the point where you're staving off hunger and counting calories. I also think it's also important to recognize your cravings - its fine to indulge once in a while (for me, with chocolate) as long as you keep it in moderation.
