I didn't read the whole article because I got a sudden itch to play the piano. But, I remember learning mitochondrial DNA is stronger, as far as what's passed on to the child - hence why more men are born colorblind or with sickle-cell anemia than women (Y chromosome doesn't carry either of these, automatically upping the chances if the mother passes it on). Then, everything you put into your body alters DNA/rNA transcription (anatomy/physiology was years ago and not a part of my career, though I'm fascinated), whether good or bad.  Once DNA is altered, it can - but not 100% positive - be passed onto children, though it won't be expressed within the first generation. Like, blue eyes; the parents of the first blue-eyed person didn't have that color, but they had the gene given to them from their parents.  Anyway, after skimming, it does makes sense to me. Most people my age (late 20's -mid 30's) have young children or are starting families, and their parents were the generation exposed to easily processed junk foods and possibly both their parents working (recession in the 70's). So, my parents and their generation started the bad habits and poorer diets than previous generations, people my age look terrible, and their kids are fat. Kind of still a nature vs. nurture thing, but it worries me not because obesity is genetic, but perhaps the genes that control where fat is stored are being altered from safer places (hips and legs) to more dangerous places because of the introduction of crap food circa 1950, which may also screw with satiety hormones. Not sure if fat distribution affects satiety, but I know stomach fat can screw with hormones. Damnit, now I've just confused myself. Gonna play piano, will get back to this.
