Eat real food.

I haven't read Nina Planck's book, but I have been a proponent of real food for a few years now. (I am still trying to get over my childhood aversion to vegetables, which derived in large part from the fact that my family served only the canned kind. ) But butter is better than margarine, period. Real food is more satiating than fake food. And once you start down the real food path (homemade sauces and pesto, etc.), it's hard to go back to the over-sweetened chemical cocktails.

All this reminds me of Famine's business plan from Good Omens:

"CHOW^TM contained spun, plaited, and woven protein molecules, capped and coded, carefully designed to be ignored by even the most ravenous digestive tract enzymes; no-cal sweeteners; mineral oils replacing vegetable oils; fibrous materials, colorings, and flavorings. The end result was a foodstuff almost indistinguishable from any other except for two things. Firstly, the price, which was slightly higher, and secondly, the nutritional content, which was roughly equivalent to that of a Sony Walkman. [...]
MEALS^TM was CHOW^TM with added sugar and fat. The theory was that if you ate enough MEALS^TM you would a) get very fat, and b) die of malnutrition."
