A quote from the article:

"The risk of weight-related illness rises when your weight goes up. For example, if you already have insulin resistance, type II diabetes, or heart disease, then you need to lose weight. If you don’t have these illnesses, you can be overweight and healthy, depending on certain health markers. According to Dr. Nadolsky:

You can still be healthy and overweight. While the BMI cutoff of overweight is 25 to 30, there are plenty of individuals who are healthy in this range. We generally look closer at metabolic markers of health when in that range and also distribution of weight and body composition. Blood pressure, glucose, and lipid markers must be examined as well in order to determine risk profile."
