Step-by-step explanation:
A fad diet is a type of diet that becomes popular for a short period of time and often promises quick weight loss results. These diets can be very restrictive in terms of food choices and may involve extreme measures. For example, the keto diet, which is a popular fad diet, restricts carbohydrates and promotes high fat intake to induce a state of ketosis in the body.
Fad diets often lack scientific evidence to support their claims and can be potentially harmful to one's health. They may lead to nutrient deficiencies, muscle loss, and rebound weight gain. It's important to approach dieting with a balanced and sustainable approach instead of relying on fad diets.
