The earlier video I mentioned was Are Cats or Dogs More Protective for Children’s Health? (http://nutritionfacts.org/video/are-cats-or-dogs-more-protective-for-childrens-health).
Viruses may also play a role in obesity. See Infectobesity: Adenovirus 36 and Childhood Obesity (http://nutritionfacts.org/video/infectobesity-adenovirus-36-and-childhood-obesity/). An Obesity Causing Chicken Virus (http://nutritionfacts.org/video/obesity-causing-chicken-virus) may help explain the link found between poultry consumption and weight gain (see Chicken Big: Poultry and Obesity (http://nutritionfacts.org/video/chicken-big-poultry-and-obesity)).
The important question is Can Morbid Obesity Be Reversed Through Diet? (http://nutritionfacts.org/video/can-morbid-obesity-be-reversed-through-diet). That’s why I made the video!
