TREAD LIGHTLY

I gather epigenetics appear to play a rôle in the Geographical distribution of obesity; it seems to appear more frequently in regions which experienced hardship a generation or possibly two generations ago (when the egg that became you was in your mother's ovary, while it developed in your maternal grandmother's womb). A quick google for "epigenetics starvation" brings up a Time magazine article on the subject. (For some reason the browser won't let me paste the address.) I've heard that this may go a long way to explaining the distribution of these problems on the above maps. It just suggests to me that it's more complex than "people here are less physically active, therefore…"

I agree that there is more to it than just physical activity, but it's a piece of the puzzle, and I think an important one. At least from my own experience, I out on weight when my mileage goes down, tend to lose when it goes back up. Anecdotal yes, but I know the formula for my body.

I've just finished the chapter on nutrition. I'm in better shape than I have been for a while, but it would be good to lose the rest of that paunch. Maybe with exercise and heeding your advice on diet I Will eventually pull it off.

Anyway, I'm really enjoying reading the book, especially as it's full of those facts that we've been waiting to see in one place.

Thanks, glad you're enjoying it!
