The Role of Epigenetics in the Obesity Epidemic

Epigenetics may explain why a baby born to an obese surrogate mother with a skinny biological mom may harbor a greater risk of becoming obese than a baby from a big biological mom born to a slim surrogate.

There are other ways by which we are what our moms ate:

Thanks for watching. I hope you’ll join in the evidence-based nutrition revolution!

First time I’ve heard anyone discussing epigenetics in relation to diet. Very interesting subject that is barely understood in all aspects, let alone dietary effects.

Such an insightful video, epigenetics affects us much more than we think.

Don't eat less, eat smart! 🌱💚💪🏻😊

More on epigenetics please!!! This is fascinating and it needs to become more common knowledge.

[bettyglick]

2:06 wow. That is an incredible statistic. Speaks volumes about how important our diet is, affecting us and future generations..

[chrismd]

Epigenetics is waaaay under discussed imo

[angelavasiliu]

Amazing info! Thank you! Please keep these videos coming.

The methylation and demethylation involved in epigenetics make sense as it may allow organisms to adapt in subtle ways aiding in their survival. Good video.

I also saw a similar study about sperm health. Obese men’s sperm have negative changes which are reversed after weight loss.

Thanks for the revelation, Dr G. No wonder non of my kids can get fat. When i was pregnant i cannot gain more than 7kg even when i tried my hardest & eat the most calorie dense food like fat & cakes. However whenever i’m pregnant, i always crave that chinese soft tofu pudding w/ sweet ginger soup.

Thanks. But the very last point, "not an all or nothing proposotion" wasn't clear to me. Does it mean that obese mothers who lose weight before pregnancy reduce risk to the child, even though they may safely gain weight again after the child is delivered? Or, delivered and weaned.

[JayAntoinette]

Wow.. I knew a mother's health and weight were important during pregnancy but this information is still startling. 😳

I just watched this Chef AJ interview, and I am honestly just interested in a review of the study to double check this since it was discussed in the interview. It wasn't the nicest, but I don't think he meant any disrespect. I hope not because Dr. Greger is my hero.

20:50 is where it starts.

My kids were all born over 8 lbs and they're all thin adults. Hmmmm...

[ddpwe]

Wait, so we're saying that people who are over weight don't over eat if their mother/grandmother was overweight when they had their kids? I could have sworn, no matter what is wrong with you biologically, calories in, calories out. This is just going to give those who are over weight more excuses not to put the fork down. Eating less(properly) is so hard to do. smh

[carfusz]

Did he just use a lot of big words to say the healthier the mom, the healthier the baby?

[zukodude]

Maybe the leaner mom had less junk in the house making the kids less likely to have junk available 🤨🤔🧐🤓

[Heidi_]

Absolutely! Obese women seldom can get pregnant but if they do guarantee the babies will be predisposed to obesity.
