BMI charts like this are ridiculously outdated.
That’s what this is - BMI. It’s misleading and doesn’t take a person’s overall muscle mass or body fat percentage into consideration. This chart makes absolutely no distinction between weight gained from fat stores and weight gained from lean tissue - It literally does not comment on your health, nor was it ever intended to. Instead, it lumps everyone of a certain height together into one group, regardless of their activity levels, genetics, body composition, medical history, frame size and age.
Your height is not the sole determinant of how much you can weigh while being healthy. It is one variant among many. To say that height and weight are so strongly linked is to ignore every other aspect of your health and physiology.
There is nothing inherently good about being 5’7” tall and 123-164 pounds. Targeting that weight is rather arbitrary for most of us. For some people, that will be far too thin and for others it will be far too fat. The healthiness of our body composition is going to depend on whether or not we are actually healthy at that weight. If you are 5’7” and 210 pounds, but you are suffering from no issues with blood pressure, cholesterol, insomnia, blood sugar levels, etc, then that weight is fine for you. It can even be your personal Target weight. Problems only occur once you start to develop medical trouble that directly stems from your weight. And even in that case, considering that “good health” will look and feel different for everyone, it does not mean that your weight is something that has to change.
Please stop promoting the concept that there is a universal ideal weight for everyone. Our bodies are not the same and they will not always function in the same way. Trying to force the same standard onto everyone is just a way of ignoring an individual’s personal health.
