I really enjoyed this page on permanent weight loss, particularly this part (emphasis added):
Here are two views on healthy eating.
First, the demonic view: Look at everything you are currently eating. Delete the foods that are too sweet, too fatty, or junk. Oh no! There’s almost nothing left? We’re going to starve! Must find food now! Must eat now! Eat to live!
The other view is that there is a lot of really good food out there. Adopting a healthier diet can open up lots of new choices.
The bad part of living in an age of abundance is that we overeat. The good part is that there is an amazing variety of wonderful, affordable, good foods available to you every day. It will take some study, but your efforts will be rewarded.
