                                Originally popularized in the 1980s by authors Harvey and Marilyn Diamond, the Fit 4 Life diet is an eating plan that operates on the core, though scientifically disputed, principle of food combining. This holistic approach emphasizes eating whole, unprocessed foods and aligning meals with the body's natural digestive cycles.
