In which scenario might high visceral fat levels be less evident using BMI?

High visceral fat levels might be less evident using BMI in a scenario where there is high fat in both the stomach and lower body. This is due to the nature of BMI as a measurement that only considers weight in relation to height, failing to differentiate between fat distribution in different body areas. When there is a significant accumulation of fat in both the stomach (where visceral fat is typically stored) and the lower body, the overall BMI may still appear within a "normal" range, potentially obscuring the actual visceral fat levels.

In contrast, individuals with isolated fat in particular regions, like excess fat in the arms or with low activity levels, may exhibit different body shapes that would contribute to a higher overall BMI, which is more revealing of an increased fat percentage. High water retention could also influence weight without directly impacting body fat levels, but it typically would not affect the visibility of visceral fat as much as the fat distribution described in the correct scenario. Therefore, the combination of fat in both the stomach and lower body can maintain a BMI that does not accurately reflect the visceral fat levels present.
