Anyone know of scientific literature on the biologically rooted psychological changes which might occur due to changes in body mass? I always assumed that weight loss or gain induced personality changes because of differences in the social acceptability of an individual's weight, but am wondering about the possible shifts in the body's biochemical pathways due to change in the amount of body fact. I began to wonder about this because of the average increases in body mass over the past generation, and what social and cultural ramifications it might have besides those of health.
