Ludicrous.
All top endurance runners are very slim.
She is just tall compared to the East Africans are typically well below average height for a woman and so it accentuates her build. She is not even that tall 5'9 or 10. Nesxt to a load of 5'2 short arses she stands out. Their body fat would be very similar.
When I was running I could get down to 10st 7lb or even 10st 5 to 6 foot (why don't Americans use stone if you are going to stick with imperial do it right. Stone Pound ounce dram.
Anyway sneaked into a race for top uk runners and my dad said I looked like a body builder next to them. I could get my weight down purely by training but an international once said I had legs like a rugby player. Well that's not really a runners legs!
Look at Mo Farah that's what it takes. Bekele & Geb only looked slightly more bulky because they are both very short as are a lot of distance runners -less weight
A lot of wester distance runners are slightly overweight or bulky for distance.
A lot of it is down to severe diet restriction of East Africans. The look like typical Brits 100-120 yrs ago. They are half starved it affect height as well. An Ethiopian international told me of the lack of food growing up. Plus they don't have all the crap sugar and cakes we have. One day Kenya will become developed then their runners will disappear. Sooner once everyone realises like Kipro that they're not just skin and built to run...its off the back of EPO
This whole post should really be taken down and the moderators should know better.
Salazar was banned for life partly down to his weight shaming. Eilish is just built naturally like that with JH it was whatever old Salad Bar was up to and she noticably changed
