So there is a phenomenon, which I think we talked about it the last time I was on the podcast. It's called TOFI, T-O-F-I. Thin on the outside, fat on the inside, real medical term, 1500 Medline citations coined by Dr. Jimmy Bell, neuroimager at University College London. You can be thin sick and you can be fat healthy. 20% of obese people are fat healthy. Now, 80% are fat sick, I agree.

So 20% of those people that are obese, they still could be healthy. Absolutely. Conversely, 60% of the normal weight population have the exact same diseases as do the obese. Normal weight people get type 2 diabetes, hypertension, dyslipidemia, cardiovascular disease, et cetera, et cetera, et cetera. Okay. Now they get it at a lower BMI. So it can't be the obesity because they're normal weight.
