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.

A few weeks ago, I had a video about The Best Diet for Weight Loss & Disease Prevention (http://nutritionfacts.org/video/the-best-diet-for-weight-loss-and-disease-prevention). But what triggered the whole obesity epidemic? It’s a multitude of factors, and I covered many of them in my 11-video series on the epidemic:
• The Role of Diet vs. Exercise in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-diet-vs-exercise-in-the-obesity-epidemic)
• The Role of Genes in the Obesity Epidemic (https://nutritionfacts.org/topics/the-role-of-genes-in-the-obesity-epidemic)
• The Thrifty Gene Theory: Survival of the Fattest (http://nutritionfacts.org/video/the-thrifty-gene-theory-survival-of-the-fattest)
• Cut the Calorie-Rich-And-Processed Foods (http://nutritionfacts.org/video/cut-the-calorie-rich-and-processed-foods)
• The Role of Processed Foods in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-processed-foods-in-the-obesity-epidemic)
• The Role of Taxpayer Subsidies in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-taxpayer-subsidies-in-the-obesity-epidemic)
• The Role of Marketing in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-marketing-in-the-obesity-epidemic)
• The Role of Food Advertisements in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-food-advertisements-in-the-obesity-epidemic)
• The Role of Personal Responsibility in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-personal-responsibility-in-the-obesity-epidemic)
• The Role of Corporate Influence in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-corporate-influence-in-the-obesity-epidemic)
• The Role of the Toxic Food Environment in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-the-toxic-food-environment-in-the-obesity-epidemic)

There are other ways by which we are what our moms ate:
• Heart Disease May Start in the Womb (https://nutritionfacts.org/video/heart-disease-may-start-in-the-womb)
• Maternal Diet May Affect Stress Responses in Children (https://nutritionfacts.org/video/maternal-diet-may-affect-stress-responses-in-children/)

  1. 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.

  2. I was over 9lbs at birth. I was fattest at 12, then I took over and things improved. My mother was never overweight, so it could also be the food amount consumed during pregnancy. Eat for 1.1, not for two when pregnant.

  3. If this is true this is Brilliance. Now one wonders if other lifestyle choices also set your children up for problems such as if the mother had viruses that cause immune response such as cancer or MS,…

  4. 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

  5. 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.
