Oh, I do think genetics plays a part, but diet obviously has an impact. My husband calls himself a cockroach. Why? Because it seems that no matter how horridly he eats, how out-of-shape he is, how very very overweight he is (300+ pounds), he does pretty well healthwise and can survive. Now, I admit things are starting to catch up with him.... a little bit. He still has BP that is ok (130/84 - not perfect, but not horrid) and his cholesterol is 170. His mom is very overweight, and takes a cholesterol pill. That's it. BP is fine. Blood sugar is fine.
Me? My BMI is fine although I know I have a little extra fat to lose, and my BP gives me all sorts of problems. I need to be SKINNY to keep my BP down to good numbers. My mom is the same, overweight and therefore on tons of medications with all of the SAD ailments. If I don't adhere strictly to a healthy diet, my numbers go haywire and I get splitting migraines. I've had gallstones, acne, joint aches, all related to the SAD in the past years even though overall I have eaten at a healthier level than my husband. We both agree about this.

A lot of this really does seem to be genetic. I can't think of any other reason than fortunate genes.
Well, I would disagree with that - I personally believe that it isnt good genes one inherits from one's parents - its good/bad eating and exercise habits.
