Nice tool and thank you for posting it and bringing out attention to it
Healthy weight is part of the picture. A healthy weight person is not necessarily a healthy person, although obesity is definitely unhealthy and very risky. What you consume is also vitally important; a person can maintain a healthy weight on a high fat, high sugar, low fiber, low nutrient diet, unfortunately. Weight is one part of the issue, eating to nuture the inside as well as the outside is another and important part.
