bottom line is it is all genetics and where your ancestors were from.
the upside of the article is it makes people that are overweight and obese feel better.
the downside of the article is it would cause some people that REALLY need to lose weight to say, hey, I don’t really have to try losing any more. And given weight loss IS difficult, I’d say MORE people would jump to that conclusion.
We all know northern Europeans can handle the extra weight, sometimes up to 50-100 lbs and they still do not have metabolic findings such as diabetes and cholesterol and hypertension.
And we all know southern Europeans can probably handle just 20-30 extra lbs on them.
Most Americans are of mixed origin, unless you know you are of pure German stock, you are still better off trying to aim for the low end of overweight or normal weight.
