You would not think what goes as "obese" those days when you ask a doctor - my boyfriend, 49 years, 1,85 m tall, arrived at 94 kg last year. Admittedly, a lot of those kilos were at the belly.
His doctor used the "obese"-word (which my boyfriend felt as an insult) and strongly advised him to lose 14 kgs. Which he managed (over the period of 6 months), for the sake of his health and the fact that ALL his trousers didn't fit any longer.
Sverre Magnus is 13. He'll hopefully lose those extra kilos when he grows another 10 to 20 cm, but currently, I'd also say that's too much of a fat roll he has at the belly, and also the rest of his frame looks rather heavy.
Haakon was rather slender at the same age:
I haven't weighed myself for a long time, but most of the time (since puberty) I weighed 80 kg. Even when I looked rather slender. Never had comments from doctors, some were even surprised I was 80 kg. The past couple of years I gained a muffin top, in other words extra body around my belly (especially) and hips. I want to decrease it myself, but still have to find a suitable way of extra exercise and such.
But to come back to the topic. My dad has always been the biggest in size of his brothers and sister. Often warned by non-professionals for vascular and heart diseases. He indeed ended up with one, but according to the surgeon and cardiologist his body was in very good health. His legs were even that muscled that they had a hard time to get the vein for a bypass. While my dad's 2 year older brother was always very slender (and still is) suffered from a heart infarct. Fortunately he survived it in relative good health, but based on his weight and appearance nobody expected this. So appearance doesn't predict all, but you have an increased change.
Recently friends and I were wondering if children in NL and Europe are getting bigger these days. In comparison how we ourselves were at that time. Are we following the USA with regard to size?
