3. Q3Short answer·2 marks
   Dietary fibre gives the body no usable energy, yet it is included among the components of a sportsperson's diet. Explain why it is included in the diet.
   Show answer and step marks

   1. Fibre passes through the digestive tract largely undigested, adding bulk to the stool and keeping bowel movements regular, which prevents constipation.+1
   2. Fibre makes the stomach feel full for longer, which helps control food intake and maintain a healthy body weight.+1

   Answer: Dietary fibre aids digestion by preventing constipation and gives a feeling of fullness that helps control food intake and body weight.
4. Q4Short answer·3 marks
   Meera is a 16-year-old hockey player whose body needs about 2800 kcal each day for training and school. Before a tournament she starts eating only 1200 kcal each day to lose weight quickly. (a) Calculate the daily energy deficit Meera creates by eating 1200 kcal instead of 2800 kcal. [1] (b) Explain why this crash diet can reduce her performance in hockey. [2]
   Show answer and step marks

   1. (a) Daily energy deficit = $2800 - 1200 = 1600$ kcal.+1
   2. (b) Very low energy and carbohydrate intake leaves her muscles and liver with little glycogen, causing fatigue and poor endurance during matches.+1
   3. (b) The body breaks down muscle protein for energy, so strength falls and recovery between training sessions becomes slower.+1

   Answer: (a) 1600 kcal per day. (b) Low energy and glycogen cause fatigue and poor endurance, and muscle protein breakdown reduces strength and slows recovery.
5. Q5Short answer·3 marks
   Ritu spends about two hours each day travelling by bus and sitting through lectures. She wants to keep a healthy body weight without skipping meals or following a strict diet. Explain how she can balance the food she eats with the energy her body uses during the day.
   Show answer and step marks

   1. Energy intake from food should roughly equal the energy the body uses (basal needs plus physical activity), so that body weight stays healthy.+1
   2. She should choose balanced meals with cereals, pulses, milk, fruits and vegetables, and avoid fried or sugary snacks on the bus.+1
   3. She should add physical activity, such as walking to the bus stop or climbing stairs, to use up extra energy.+1

   Answer: Ritu should match her energy intake to her energy use by eating balanced, nutritious meals and snacks and by staying physically active during the day, without skipping meals.
