257: What Is a Diet, Really? Why We've Misunderstood the Word "Diet"

from Real World Nutrition · host Shelley A. Rael, MS RDN LD

What does the word "diet" actually mean? For many people, the word immediately brings to mind weight loss, restriction, food rules, and giving up favorite foods. But the original meaning of diet is much simpler: it is the pattern of foods and beverages a person typically consumes. This episode looks at how the word diet became so closely associated with weight loss and restrictive eating, why everyone has a diet whether they consider themselves "on one" or not, and how dietary patterns differ from short-term weight-loss plans. Topics include the non-diet approach, the idea that all foods can fit into an overall eating pattern, and why medically necessary dietary restrictions are different from arbitrary rules promoted by fad diets. This episode kicks off a series that takes a closer look at diets, dietary patterns, and how nutrition advice can shape how we think about food and health. Read More: What Is a Diet, Really?
