Which of the following results in reduced satiety and over-consumption of nutrients?

Question

When considering the question, we must evaluate how each resistance would affect satiety and nutrient intake.
Option a: Ghrelin resistance. Ghrelin is an appetite-stimulating hormone released before meals. If there were ghrelin resistance, the signaling that increases hunger would be blunted, potentially reducing or altering meal initiation rather than causing reduced satiety and overconsumption. This makes the option unlikely as the primary driver of overconsumption.
Option b: Leptin resistance. Leptin is the long-term adiposity signal that promotes satiety and reduces food intake. When the body becomes resistant to leptin, the brain does not respond properly to leptin’s satiety cues, leading to diminished satiety after meals and greater caloric intake, which directly aligns with reduced satiety and overconsumption.
Option c: Peptide YY (PYY) resistance. PYY is released postprandially and reduces appetite. If resistance to PYY existed, the anorexigenic effect would be weakened, which could contribute to increased appetite and intake, similar to leptin resistance, but the question targets the primary or most classic mechanism. PYY resistance could contribute to overconsumption, yet it is not as central or well-established as leptin resistance in driving reduced satiety.
Option d: Insulin resistance. Insulin signaling in the brain also influences energy balance, but insulin resistance is more strongly linked to metabolic syndrome and glucose homeostasis than to a direct, consistent reduction in satiety signals alone. While it can influence eating behavior, it is not the classic, direct cause of reduced satiety and overeating compared with leptin resistance.

In summary, each option explains a mechanism that can affect appetite, but leptin resistance is the most prototypical and well-established cause of diminished satiety signaling leading to overconsumption of nutrients, making it the best match for the question.
