Question

Read the passage below and answer the following question.

It is perhaps unsurprising that fad diets are so common given the level of obesity in American society. But over the long term, most fad diets are harmful both to the health and to the waistline. Many such diets advocate cutting out one major nutrient, such as fats or carbohydrates. Others suggest fasting over long periods or eating from fixed menu options that may not meet the body’s needs. Most of these diets are highly impractical, and many lead directly or indirectly to binge eating and other unhealthy behaviors.

The topic sentence of this paragraph is:

The topic sentence of the paragraph is about the commonness of fad diets due to obesity. Fad diets are often harmful, leading to unhealthy behaviors and potential health issues. Long-term, sustainable eating habits and lifestyle changes are recommended over fad diets.

Step-by-step explanation:

The topic sentence of the paragraph you provided is: "It is perhaps unsurprising that fad diets are so common given the level of obesity in American society." This sentence introduces the main idea that the paragraph will discuss, which is the prevalence of fad diets due to obesity rates. The rest of the paragraph provides supporting details explaining why most fad diets tend to be harmful and impractical, ultimately leading to unhealthy behaviors such as binge eating.

Fad diets often promise quick weight loss and may require cutting out major nutrients or fasting, which can be detrimental to one's health. Over time, these diets can lead to malnutrition, kidney stones, gout, and other health problems. Rather than helping, they may contribute to a yoyo dieting effect, where weight is lost and then regained once a person returns to their previous eating habits.
