I got the impression that there was some data mining that supported the premise for the study. Excluding under 25YOs gets rid of large numbers of very healthy people with BMIs under 25. Focusing on the modestly overweight group excludes the anorexics/bulemics as well as the obese and morbidly obese. So if you take a group that is over 25 and slightly overweight (BMI of 25-30), you're probably getting a subset that eats well nutritionally, exercises, isn't diabetic or suffering from other serious illness. IMO, it would make more sense to compare groups with common risk factors. E.g. - Is there any significant difference in mortality for Type 1 diabetics based upon BMI? Type 2? ... Is there any difference in mortality for groups that eat well nutritionally, exercise based upon BMI?
