Weight Gain Quiz
Questions: 16 · 10 minutes
1. Why can a small serving of an energy-dense food contribute more energy than a larger serving of a low-energy-density food?
Energy density describes how much energy a food provides relative to its weight
Small servings are always digested twice
Larger portions contain no energy when they include water
The body's energy use depends only on the physical size of a meal
2. What is an important limitation of body mass index, or BMI?
It identifies the medical cause of a person's weight change
It can only be calculated for people who exercise regularly
It directly measures the amount of fluid retained by the body
It does not directly distinguish fat, muscle, bone, or fat distribution in an individual
3. Which statement best describes the relationship between ongoing stress and weight gain?
Stress may alter sleep, appetite, routines, and activity, but its effects differ among people
Stress affects weight only when a person consciously decides to eat more
Stress inevitably causes substantial weight gain in every person
Stress hormones make energy intake and expenditure irrelevant
4. Can particular foods or exercises make gained body fat go only to one chosen body area?
Yes; eating protein directs all new fat to the arms
Yes; exercising an area forces all gained fat to settle there
No; fat distribution is influenced by factors such as genetics, hormones, sex, age, and overall weight change
No; everyone stores body fat in exactly the same pattern
5. Over time, what most directly allows body weight to increase?
Meals contain more grams of food than the body weighs afterward
Carbohydrates are eaten at any time after sunset
Energy intake consistently exceeds energy expenditure, with the excess stored in body tissue
Dietary fat is eaten, regardless of total energy intake
6. Which combination accompanying unexplained weight gain is worth discussing with a clinician as a possible thyroid-related pattern?
Temporary thirst after exercise and warmth on a hot day
Muscle soreness after a new workout and improved appetite
Brief hunger before lunch and tiredness after staying up late
Persistent fatigue, feeling unusually cold, and constipation
7. Two people add similar amounts of food to their usual diets but do not gain the same amount of weight. Which explanation is most accurate?
Only one of them must be reporting honestly
Equal portions always produce identical weight changes in every person
Food energy stops mattering for anyone with a fast metabolism
Differences in activity, body size, physiology, absorption, and adaptation can affect the result
8. Sam is underweight and has been advised to gain weight. Which approach generally supports nutritional quality while they arrange appropriate professional guidance?
Rely mainly on sugary drinks because nutrients do not matter during weight gain
Add regular meals and snacks with energy-rich, nutrient-dense foods and adequate protein
Skip daytime meals and eat one very large meal before bed
Avoid strength activity because gained weight should never include muscle
9. Maya weighs 1.5 kg more the morning after a salty restaurant meal. What is the most likely short-term explanation?
Temporary water retention and the weight of food still being digested
She gained 1.5 kg of muscle while sleeping
All of the meal's energy was immediately converted into body fat
Her scale can no longer provide any useful information
10. Someone notices gradual weight gain after starting a prescription medicine. What is the most appropriate response?
Stop the medicine immediately without advice
Assume the medicine cannot be involved because prescriptions do not affect weight
Discuss the timing and possible effects with the prescriber before making changes
Double the next dose to test whether the medicine is responsible
11. Jordan begins progressive strength training and gains weight while their waist measurement changes little. What could reasonably explain part of the gain?
Waist measurements always shrink whenever muscle increases
Exercise has permanently stopped the body from using energy
Every kilogram gained during strength training must be body fat
An increase in muscle tissue and its associated water storage
12. A person's weight rises quickly over several days, and their shoes and rings feel unusually tight. What does this pattern particularly suggest?
A large increase in skeletal muscle from ordinary daily movement
Fluid retention, which may need medical assessment depending on its cause and symptoms
A permanent change in bone length
Proof that one particular food has caused lasting fat gain
13. Which weight-related situation calls for urgent medical help rather than waiting to take an online quiz?
Rapid gain or swelling accompanied by breathing difficulty, chest pain, fainting, or severe symptoms
A small difference between morning and evening measurements
A gradual change after routinely eating larger portions
A slow increase after several months of strength training
14. Alex wants to know whether their weight is truly trending upward rather than fluctuating day to day. Which method is most informative?
Compare a morning measurement with one taken after dinner
Use several different scales and keep only the highest reading
Measure under similar conditions and examine the pattern across several weeks
Judge the trend from how tight one outfit feels after a meal
15. Which statement about aging, menopause, and weight is most accurate?
Menopause makes major weight gain unavoidable for everyone
Hormonal, muscle, sleep, activity, and lifestyle changes can interact, but individual experiences vary
Age-related weight change is caused only by hormones
Body composition cannot change after early adulthood
16. How can regularly insufficient sleep contribute to weight gain for some people?
It creates body fat without any connection to behaviour or physiology
It can affect appetite, food choices, energy regulation, and willingness to be active
It prevents the digestive system from absorbing any nutrients
It guarantees the same amount of weight gain in everyone
