Words matter and your weight cannot determine whether you are "healthy", the "normal".
First, scales do not measure the presence or absence of health, so the term "healthy weight"means literally nothing.
Second, the CDC defines a "Normal weight"as one giving a person a BMI of between 18.5 and 24.9 if we used the word correctly, it would vary by country and would reflect the average BMI of its population. So in Nauru for example the normal weight would be one a person with a BMI of 32.5, while in Eritrea there would be someone with a BMI of 20.5. Since the median BMI in the US and Canada is 28.8 and 27.2, respectively, in North America, must be taken into account unusual have a BMI between 18.5 and 24.9.
What can we use instead of this?
Weight, while not a guarantee of any medical problem, increases the risk of many, and so I suggest that instead of conditions giving rise to a crisis, we categorize weight as low risk, medium risk and high risk, and in doing so we will stop incorrectly use of healthy and normal a term that constantly and hybridly promotes weight bias, shame and stereotype.
