Thanks to everyone who attended my presentation at the 2012 Ancestral Health Symposium, “What Is Hunger, and Why Are We Hungry?”
Update: The video is now available! Click here to watch it.
Meanwhile, here are the references for the facts I discussed, and the data sources for the graphs in my slides.

Satiation, satiety and their effects on eating behaviour
There are many Berridge papers on the subjects of hedonic impact (‘liking’) and incentive salience (‘wanting’). These are available as fulltext:
Curr Opin Pharmacol. 2009 Feb;9(1):65-73. Epub 2009 Jan 21.
Dissecting components of reward: ‘liking’, ‘wanting’, and learning.
Berridge KC, Robinson TE, Aldridge JW.
Neurosci Biobehav Rev 20(1) 1-25, 1996.
Food reward: Brain substrates of wanting and liking.
Satiation and Satiety
Gastroenterology. 2010 January; 138(1): 65–72.e1-2.
Dietary Fiber Supplements: Effects in Obesity and Metabolic Syndrome and Relationship to Gastrointestinal Functions
Athanasios Papathanasopoulos, M.D. and Michael Camilleri, M.D.
[Note that the studies whose only intervention was additional fiber resulted in zero or insignificant weight loss, whereas the studies that resulted in significant weight loss were compound interventions of which fiber was only one minor component.]
