I sure will.
4:09
And that's a loaded question because obesity has so many moving parts, okay? And genetics absolutely plays a role.
4:20
For sure.
4:20
We do know that genes, studies that were done in...
4:28
Kaiser and the CDC years ago shows that there's genetic with twins and adoptions shows that the genetic pool, 40 to 70% of individuals have genetic association with obesity.

So say, for instance, if there is an adopted child with cancer, non-biologic parents that adopted child will carry the genes that their biologic parents have so that body habitus is typical of the parents that they were born from sure and similar with twins we do see that but environment certainly impacts all of that and environment is a loaded loaded gun okay yeah because access to good healthy foods Especially now with the production of all of the ultra processed foods that are out there, say the corn, the soy and the wheat products.
