ISSA Case Analysis & Practical Application 3

Question 1

A 17-year-old male wrestler is trying to cut 8 pounds in 2 weeks before competition. He plans to severely restrict water intake. What is your PRIMARY concern?

Accepted Answer

Severe dehydration impairs performance and poses serious health risks

Answer

Rapid dehydration used for weight cutting significantly impairs physical performance and can cause dangerous health complications.

Question 2

A 40-year-old client with hyperlipidemia has total cholesterol of 240 mg/dL and high LDL. Which dietary change has the STRONGEST evidence for lowering LDL cholesterol?

Accepted Answer

Replace saturated fats with unsaturated fats and increase soluble fiber

Answer

Replacing saturated fats with unsaturated fats and consuming soluble fiber (e.g., oats, legumes) are the most evidence-based strategies for lowering LDL.

Question 3

A client reports following a ketogenic diet but is experiencing headaches, fatigue, and irritability in the first week. What is the MOST likely cause?

Accepted Answer

Electrolyte and fluid loss as glycogen stores are depleted

Answer

Glycogen depletion during keto adaptation releases stored water, causing electrolyte losses that produce the 'keto flu' symptoms.

Question 4

A 35-year-old male bodybuilder consumes 4,500 kcal/day during a bulking phase. His macros are 60% carbs, 25% protein, 15% fat. What concern should you address?

Accepted Answer

Fat intake is too low and may impair hormone production

Answer

Fat intake below 20% of total calories may compromise testosterone and other steroid hormone synthesis, which is critical for muscle building.

Question 5

A 62-year-old client recovering from hip replacement surgery asks about nutrition to support healing. What is the MOST important macronutrient to emphasize?

Accepted Answer

Protein, to support tissue repair and prevent muscle wasting

Answer

Adequate protein (1.2–2.0 g/kg) is critical post-surgery to support wound healing, tissue repair, and prevention of sarcopenia.
