What is a characteristic of a fad diet?

A characteristic of a fad diet is the claim of effortless weight loss. Fad diets often promise quick results with minimal effort, leading individuals to believe that they can achieve their weight loss goals without making significant lifestyle changes or adhering to a balanced diet. This appeal can make these diets particularly tempting, as they typically suggest that followers can eat whatever they want without needing to exert the effort typically associated with successful, sustainable weight management.

In contrast, other options highlight essential components of healthy eating and sustainable weight loss strategies, such as balanced nutrition or guidance from health professionals, which are generally not emphasized in fad diets. Fad diets tend to lack the support of professionals and may not promote lasting lifestyle changes, focusing instead on short-term results, which is why the claim of effortless weight loss stands out as their defining characteristic.
