Why 5 Lbs of Fat Is Necessary
I’ve come to realize that 5 lbs of fat is not just “extra weight” — it can actually serve a useful purpose in my body. My fat stores help protect my organs, support hormone production, and give me a reserve of energy when I’m not eating enough or when I’m going through a stressful period. In that sense, a small amount of fat is part of what keeps my body functioning properly.
I also notice that having some fat helps my body stay warm and provides cushioning for my joints and bones. My body is designed to keep a certain amount of stored energy, and that reserve can be especially important if I’m sick, recovering, or more active than usual. Without enough fat, I may feel weaker, colder, or less resilient.
So, for me, 5 lbs of fat can be a normal and necessary part of being healthy. It’s not just about appearance — it’s about balance, protection, and having the energy my body needs to work well every day.
