So there is a definite lack of good weight forum. It's all basically owned by people with no incentive to advance technologies and create cures such as gene therapies or it's not getting alot of attention.
I'd like to add a weight loss section to the Lifestyle forum that would be separate from calorie restriction. I'd start by moving topics from around the forum on the subject of weight loss to it and start conversations to that effect.
Weight loss is a giant industry, and an easy target for improvement by futurists such as ourselves who are looking to new technologies and self experimenting with things.
