One of the current “fat” gags going the rounds jokes that if you step on the scale and the little window reads “To be continued” then you know that you need to lose weight. Funny? Well, maybe. However, obesity is no laughing matter. It’s a serious disease at epidemic proportions. Dr. Joseph Mercola, author of The No Grain Diet, maintains that “a staggering 61% of American adults currently meet the scientific definition of obesity, putting them at increased risk of heart disease, diabetes, stroke, arthritis, depression and several forms of cancer. Obesity rates among US adults have gone up 30% since the late 1970s.” The statistics for Canada show a similarly depressing picture.
