I saw this ad for fast food at a bus stop in downtown Chicago last night.  I disagree!

Dr. David Kessler, who used to run the FDA, has published a fascinating book, “The End of Overeating: Taking Control of the Insatiable American Appetite” (Rodale) – see book review in the NY Times. His work suggests that the food industry purposely sets out to find the combinations of fat, sugar, and salt that addict us. Yes, fast foods can “light up” the same areas of the brain that cocaine and heroin do!
For me, therefore, I have avoided these foods completely. After a couple of weeks of withdrawal, I became perfectly satisfied by the foods I eat – complex carbs, low fat meats (steamed), fish (steamed), lots of green veggies (nuked with 1 teaspoon olive oil). I add spices, not fat, sugar, and salt, for flavor.
