Question

what happens to the levels of ghrelin and leptin hormones as you age and become less physically fit? (1 point) ghrelin increases and leptin decreases. ghrelin and leptin both increase. ghrelin decreases and leptin increases. ghrelin and leptin both decrease.

Explanation:

Ghrelin is a hunger - stimulating hormone, and leptin is a satiety - promoting hormone. As people age and become less physically fit, body composition changes (often with increased fat mass). Fat cells produce leptin, so more fat mass leads to increased leptin production. At the same time, with age and reduced fitness, the regulation of ghrelin can be disrupted, and ghrelin levels tend to decrease. So the correct relationship is that ghrelin decreases and leptin increases.

Answer:

Ghrelin decreases and leptin increases.
