When your ripped six pack is covered by a thick layer of fat.

A
Correct answer
Explanation
Yo-yo dieting causes repeated metabolic stress, weight cycling, and cardiovascular strain. The rapid weight fluctuations are harder on the heart and organs than maintaining a stable overweight status. This pattern can increase risks of hypertension, inflammation, and metabolic syndrome.

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.
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.

-
that laughing is a common cause of death
-
that a few people are reported to have died while laughing
-
laughing makes heart weaker
C
Correct answer
Explanation
While extremely rare, there are documented cases of people dying from laughter, typically due to heart failure or asphyxiation. The most famous historical case is the Greek philosopher Chrysippus (3rd century BC) who reportedly died of laughter after watching a donkey eat figs. Modern cases include fatalities from laughter-induced cardiac arrhythmias or rupture of the weak blood vessels in the brain from excessive laughing.
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.
