Which dietary strategy is supported by evidence for preserving lean muscle mass during a caloric deficit?
Answer: Adequate dietary protein (1.6–2.4 g/kg body weight)
Research consistently shows that consuming 1.6–2.4 g of protein per kg of body weight during a caloric deficit helps preserve lean mass by supporting muscle protein synthesis.
The 'set point theory' of body weight suggests that:
Answer: The body defends a biologically preferred weight range through metabolic and hormonal adjustments
Set point theory proposes that the body uses hormonal and metabolic mechanisms to resist deviations from a defended weight range, making sustained weight loss physiologically challenging.
Which measurement tool provides a quick field assessment of relative body fat distribution by comparing waist size to hip size?
Answer: Waist-to-hip ratio (WHR)
Waist-to-hip ratio divides waist circumference by hip circumference to assess fat distribution patterns, with higher ratios indicating greater central (android) adiposity.
A client's body composition shows 30% body fat. After a 12-week program they are at 27% body fat with no change in scale weight. What most likely occurred?
Answer: The client gained lean mass and lost an equal amount of fat mass (body recomposition)
Body recomposition — simultaneous fat loss and muscle gain — can occur with adequate protein, resistance training, and modest caloric deficit, resulting in improved body composition without scale weight change.
Which behavior change technique involves helping a client identify internal triggers that lead to overeating?
Answer: Self-monitoring and stimulus control
Self-monitoring (food journaling, hunger tracking) and stimulus control (identifying and modifying environmental cues) are evidence-based cognitive-behavioral techniques for addressing emotional or triggered eating.
According to the Dietary Guidelines for Americans, what is the recommended maximum percentage of daily calories from saturated fat for weight management and cardiovascular health?
Answer: 10%
The Dietary Guidelines for Americans recommend limiting saturated fat intake to less than 10% of total daily calories to reduce cardiovascular disease risk.
