Summary
Explore the science behind fast diets versus healthy weight loss in this B2 English lesson. Students will discuss diet experiences, analyze a video on different dieting approaches (focusing on glycogen use and metabolic responses), and learn key terms like fad diets, energy deficit, and sustainable practices. The primary grammar focus is the passive voice, emphasizing its use in scientific contexts to describe processes objectively. Activities include vocabulary matching, comprehension tasks, and extensive practice transforming sentences and writing about health using the passive voice.
Activities
Discuss diet experiences and opinions: Students share personal views on dieting, societal pressures, and healthy weight management, fostering conversation and critical thinking about various health and lifestyle approaches.
Analyze a video on dieting science: Learners watch a video comparing rapid versus gradual weight loss, focusing on concepts like glycogen stores and metabolic effects, and answer detailed comprehension questions.
Master vocabulary for health and diets: Through contextual reading and matching exercises, students learn and practice key terms such as fad diets, energy deficit, starvation response, and sustainable.
Practice the passive voice for scientific descriptions: Students engage in multiple exercises transforming active to passive voice, completing sentences, and describing physiological processes related to diet and weight loss.
Vocabulary focus
This lesson focuses on crucial vocabulary for discussing health and nutrition, including terms like fad diets, energy deficit, glycogen, releases (verb), starvation response, detoxification diets, compromise (verb), restrict, promote, regimens, sustainable, and maintained. Understanding these terms will help students articulate concepts related to various dieting methods and their physiological impacts more accurately.
Grammar focus
The primary grammar point is the passive voice (form: to be + past participle). Students will learn why it's frequently used in scientific and health contexts—to emphasize the action or process rather than the agent, to describe procedures, and to present information objectively. Exercises cover forming the passive in different tenses and applying it to describe health-related phenomena.
