Originating in the 1930s when dieting first became popular, the Grapefruit Diet has endured over the years, going in and out of fashion and outlasting many other food “fads.” This low-carb regimen, which was also called the Hollywood Diet, centers around (you guessed it) the fat-burning powers of grapefruit. Early versions of the diet were very low calorie—as low as 585 calories per day. There are numerous variations today; most of them suggest eating around 800–1,000 calories daily. Here’s a sample Grapefruit Diet menu that we found online. Keep in mind that this plan is designed for short-term use, around 10–12 days.

The Story of Better Nutrition was founded by Jack Schwartz in 1938. Schwartz returned from the military with a business idea—start a magazine about nutrition. He loved helping friends and family find natural solutions to health problems, and he figured others would be interested in this too. He saw an opportunity to fill a niche and, at the same time, satisfy his passion for health and nutrition. And just like that, Better Nutrition magazine was born. Fall back in time with us this year as we revisit popular trends in nutrition, vitamins, recipes, and more with this limited-edition section.
