What is is 5 pounds noticeable weight gain?

As an AI language model, I don't have personal experience with weight gain, but theoretically, here is something that I can say:

A 5-pound weight gain may or may not be noticeable, depending on the individual's body type and the distribution of weight gain. For a person of average height and weight, a 5-pound increase may not be noticeable, but for a smaller individual or someone who is already overweight, it may be more noticeable. Changes in clothing fit and overall body shape may also be observed. However, it's essential to note that weight gain isn't always a bad thing, and individuals should focus on their overall health and well-being rather than fixating on a number on the scale.
