What is is a 5 pound weight gain noticeable?

As an AI language model, I don't have personal experience of weight gain, but in general, a 5-pound weight gain may be noticeable to some people, while others may not notice it at all. Factors that can affect how noticeable the weight gain is include a person's height, body type, and the distribution of the extra weight. For example, a 5-pound weight gain may be more noticeable on someone who is shorter and has a smaller frame, while it may not be as noticeable on someone who is taller and has a larger frame. Additionally, if the extra weight is concentrated in one area, such as the stomach, it may be more noticeable than if it is distributed evenly across the body. Ultimately, whether a 5-pound weight gain is noticeable or not depends on the individual and their perception of their own body.
