The success I had in weight loss can be directly attributed to a simple concept -- the understanding that processed foods pack more calories into a smaller package.

Think for a second about the volume of two extremes; a thousand calories of vegetables vs. a thousand calories of vegetable oil. The former will completely fill your stomach, while the latter will barely line your stomach walls. It takes a few weeks for your palate to adjust, but once you find the pleasure of eating unprocessed fresh fruits, vegetables and grains, you will find that you can finish each meal filled and fulfilled and begin an "effortless" decline of body weight. All without the charts and graphs, and scientific explanations - just as nature intended.
