While I'm sure genetics makes a difference (as it does with everything), I doubt it's that significant. I'd be shocked if there's more than a 10% difference, if even that much.

Would love to see a source that backs up your claim.

It's enough of a difference to turn a surplus into even a deficit. Long term, it makes someone skinny or obese, or preferably normal weight.
