Nutrition, Lifestyle & Weight Management Flashcards

Which sleep-related factor most significantly impairs exercise recovery and glycemic control in clients with chronic disease?

Answer: Chronic sleep deprivation below 6 hours per night, elevating cortisol and insulin resistance

Chronic sleep deprivation elevates cortisol, promotes systemic inflammation, and impairs insulin sensitivity, compounding the metabolic burden in clients with existing chronic disease.

What is the most evidence-based recommendation for stress management to complement an exercise program for a client with cardiovascular disease?

Answer: Mind-body practices such as mindfulness, yoga, or diaphragmatic breathing to reduce sympathetic nervous system activation

Mind-body practices reduce sympathetic activation and cortisol, lower blood pressure, and improve heart rate variability — all beneficial outcomes in cardiovascular disease management.

Which supplement has the strongest evidence for reducing muscle loss (sarcopenia) in older adults when combined with resistance training?

Answer: Creatine monohydrate and leucine-enriched essential amino acids

Creatine enhances phosphocreatine resynthesis and lean mass gains, while leucine-enriched EAAs maximally stimulate muscle protein synthesis in older adults with anabolic resistance.

Which lifestyle behavior modification approach is most effective for helping a client with obesity sustain long-term caloric restriction?

Answer: Flexible dietary restraint with regular self-monitoring and personalized food preferences incorporated

Flexible dietary approaches that incorporate food preferences and monitor intake consistently outperform rigid restriction in long-term adherence and sustained weight loss.

A client with type 2 diabetes asks about the safety of post-exercise protein shakes. What is the most accurate guidance?

Answer: Post-exercise protein is beneficial for muscle repair and has minimal effect on blood glucose when carbohydrate content is modest

Protein has a minimal acute glycemic effect and supports muscle protein synthesis after exercise; shakes with moderate carbohydrate are generally safe and beneficial in well-controlled type 2 diabetes.

What is the recommended caloric deficit range per day for safe, sustainable weight loss in clients with obesity and comorbid conditions?

Answer: 500–750 kcal/day deficit to achieve approximately 0.5–1 lb per week weight loss

A 500–750 kcal/day deficit produces a clinically meaningful 0.5–1 lb/week loss without triggering metabolic adaptation or compromising lean mass preservation.
