Is fiber the key to losing weight?

I just read a report in FutureFood2050.  They often report on how our food world is changing. Make sure you subscribe to them to learn so much more about the future of our food. They have so many facts and insights that are truly astounding – why 40% of the food in the U.S. is never eaten, how flies are aiding in nutrient recycling, what’s new in meat alternatives, why the world’s girls are the missing link in global food aid programs, how 3D food printing works in space, what it will take to feed the mega-cities of tomorrow, and so much more. The one I was reading was about fiber. Back in the paleolithic era we ate 100g of fiber per day or more. Now we are eating 10-20 g fiber compared to what we used to eat. I was pretty impressed. So it makes me wonder. If I eat more fiber then will I lose more weight because I will feel fuller longer? What do you think? What’s your favorite article on the site?
