From an article by Philip Greenspun illustrating how the web allowed writers to find an audience for things that are too long for magazines yet too short for books, a simple and effective method for dieting developed by Steve Ward.
“All that you need for my diet is graph paper, a ruler, and a pencil,” Steve would explain. “The horizontal axis is time, one line per day. The vertical axis is weight in lbs.

You plot your desired weight on a desired date towards the right side, making sure that you’ve left the correct number of lines in between (one per day). You draw a line from the current weight/date to the desired weight/date. Every morning you weigh yourself and plot the result. If the point is below the line, you eat whatever you want all day. If the point is above the line, you eat nothing but broccoli or some other low-calorie food.”
