oa.mg appears to be some sort of search aggregator that wants you to buy the article for $17 even though it's open access (freely available).
Repackaging and selling free stuff is a business model that is hundreds of years old.
Occasionally, it's worth it, as the repackaging may come with some help understanding the material, or help in organizing it.
And I can sell you any GPL program I got for free, if you're willing to buy it...

Not sure why OP linked to this index. The article is Open Access, yet this intermediary site has a prominent "Buy article PDF →" link at the top which tries to sell it for $17. OA.mg seems like some kind of scam.
So do most of their recent submissions. Presumably they have a vested interest in oa.mg selling access to papers.
They previously linked to citationsy.com which came from the same team.

I bet people with high BMI but low fasting glucose and low c-reactive protein are mostly athletes, people who weight a lot due higher muscular weight. It wouldn't be surprising they are healthier.
