Ask the best looking people at your school what they think
C
Correct answer
Explanation
Doctors are trained to assess healthy weight ranges using metrics like BMI, growth charts (for children), and individual health factors. Comparing yourself to celebrities or asking non-medical people provides unreliable, potentially harmful information. Medical professionals give evidence-based guidance appropriate for your age, height, and health status.
A
Correct answer
Explanation
Regular tea consumption has been associated with numerous health benefits in scientific studies. These include antioxidant properties, potential cardiovascular benefits, possible cancer-preventive effects, improved mental alertness, and better metabolic health. The antioxidants (catechins and flavonoids) in tea, especially green tea, have been widely studied. While research continues, many health organizations acknowledge the positive effects of moderate tea consumption.
-

-
a membership in a health club is a poor investment.
-
walking outdoors provides a better workout than walking indoors.
-
fitness walking is a convenient and valuable form of exercise.
-
poorly designed athletic shoes can cause major foot injuries.
D
Correct answer
Explanation
The paragraph emphasizes that fitness walking requires no commute to a gym and minimal equipment - just good shoes. This supports the conclusion that fitness walking is convenient and valuable. Options A and C make unsupported comparative claims about exercise quality. Option B wrongly generalizes from 'no need for commute' to 'poor investment'. Option E discusses shoe injuries, which isn't mentioned.
B
Correct answer
Explanation
Not all stress is bad - stress can be positive (eustress) when it motivates and helps us perform better, like the excitement before a competition or the focus that helps meet a deadline. Only chronic or excessive stress becomes harmful to the body.
C
Correct answer
Explanation
Lime juice with honey in warm water is a traditional home remedy believed to aid weight loss and reduce obesity. The combination is thought to boost metabolism, improve digestion, and help burn fat. While lime provides vitamin C and antioxidants, and honey offers natural sweetness, this is more of a supportive practice rather than a standalone obesity treatment.
A
Correct answer
Explanation
Using a smaller plate creates a visual illusion that makes portions appear larger, which naturally leads to eating less without feeling deprived. This psychological effect, known as the Delboeuf illusion, helps reduce calorie intake while maintaining satisfaction with meals.
A
Correct answer
Explanation
After intense exercise, your body experiences excess post-exercise oxygen consumption (EPOC), often called the afterburn effect. During recovery, your body continues burning additional calories to repair muscle tissue and restore energy stores, even while you sleep.
B
Correct answer
Explanation
While diet changes alone can cause weight loss, exercise provides crucial benefits including muscle preservation, metabolic health, and sustainable weight maintenance. Without exercise, weight loss from diet alone often includes muscle mass loss and can slow your metabolism long-term.
B
Correct answer
Explanation
Even healthy foods contain calories and can cause weight gain if consumed in excess. Fat-free cookies often replace fat with sugar, and while nutritious, fruit still contains natural sugars and calories. Portion control remains essential regardless of how healthy the food appears.
A
Correct answer
Explanation
Severely restricting calories triggers your body's starvation response, causing it to slow metabolism and conserve energy. This adaptive mechanism makes weight loss increasingly difficult and can lead to weight gain even with reduced calorie intake as your body becomes more efficient at using fewer calories.
B
Correct answer
Explanation
Weight gain depends on total calorie intake versus expenditure, not the timing of meals. Your body processes calories the same way regardless of when you eat. However, late-night eating may lead to weight gain if it causes you to exceed daily calorie needs or make poorer food choices.
B
Correct answer
Explanation
The statement is false. Strength training is beneficial at any starting weight. Building muscle helps boost metabolism, increase fat burning, and preserves lean muscle mass during weight loss. Waiting to start strength training delays these important benefits.
B
Correct answer
Explanation
The statement is false. Muscle and fat are completely different types of tissue with different cellular structures. When you stop exercising, muscle tissue may atrophy (shrink) and fat cells may expand if you consume excess calories, but muscle never literally transforms into fat.
A
Correct answer
Explanation
Weight gain and obesity are complex conditions influenced by multiple factors including genetics, diet quality, physical activity levels, hormonal imbalances, medications, stress, sleep patterns, and environmental factors. Rarely is there a single cause.
A
Correct answer
Explanation
Moderately vigorous exercise increases metabolic rate, builds muscle tissue (which burns more calories at rest), and improves insulin sensitivity. These physiological changes are often essential for sustainable weight management when combined with dietary changes.
