What is the benefit of avoiding high-fat meals before flying?

The benefit of avoiding high-fat meals before flying primarily stems from the physiological effects that such meals can have on the body. Consuming high-fat foods can lead to a sensation of heaviness and can slow down digestion, potentially making a person feel lethargic or drowsy. This sluggishness can impair cognitive function, reaction times, and overall alertness, which are crucial for safe flying.

When flying, it is essential for pilots to maintain clear mental acuity and physical responsiveness. Thus, steering clear of high-fat meals helps ensure pilots remain vigilant and focused, significantly decreasing the risk of drowsiness during flight.

In contrast, increased energy levels, better communication with crew, and improved flight instrument accuracy are not directly related to dietary choices in the same manner. While energy levels can be affected by what is consumed, the specific link between high-fat meals and drowsiness is a more significant factor in this context.
