NOTE: Ensure you answer all parts of this question (a, b,

c and d).

A 25-year-old female recreational athlete weighs 95 kg and

exercises for approximately 60–90 minutes, 5 days per week. Her activity level

is classified as moderately active (PAL = 1.8). She is aiming for weight maintenance while supporting her current training load.

The athlete recently changed her diet after receiving

nutrition advice from social media. She has:

• substantially

  reduced her intake of dietary fat, including foods such as nuts, avocado

  and olive oil;

• substantially

  increased her protein intake, primarily through protein supplements; and

• an

  estimated daily energy intake of 2500 kcal/day.

Despite these dietary changes, the athlete reports feeling

fatigued during training and experiencing lower energy levels throughout the

day.

Additional information:

Schofield equation for females aged 18–29 years:

BMR (kJ/day) = (62 × body weight [kg]) + 2,035

Estimated energy requirement:

EER (kJ/day) = BMR × PAL

1 kcal = 4.2 kJ

A) Discuss two considerations for this athlete associated with consuming very little dietary fat, with reference to health and exercise performance. (2 marks)

B) Calculate the athlete’s EER. Based on the result, comment on whether 2,500 kcal/day is likely to be adequate to support her current training load, and quantify the shortfall or surplus. (2 marks)

C) The athlete obtains a large proportion of her increased protein intake from protein supplements. Identify and explain two potential concerns associated with relying heavily on protein supplements in this situation. (4 marks)

D) The athlete has changed her diet primarily in response to nutrition advice from social media. Explain two characteristics of evidence-based nutrition advice that should be considered when evaluating this type of dietary recommendation. (2 marks)
