Step-by-step explanation:
A fad diet is a type of diet that becomes popular for a short period of time and then fades away. These diets usually promise quick weight loss by restricting certain food groups or drastically reducing calorie intake. However, they are often not based on scientific evidence and can be harmful to health.
One example of a fad diet is the juice cleanse, where individuals consume only fruit or vegetable juices for a certain period of time. Another example is the keto diet, which involves consuming very low amounts of carbohydrates in order to force the body into a state of ketosis.
It is important to approach dieting with caution and consult a healthcare professional for personalized advice and guidance.
