This has me wondering whether these individuals lose weight because (a) they experience less of the scent/flavor "reward" that comes with eating and drinking tasty things and (b) therefore eat less? It stands to reason that if food tastes flat you'll be less motivated to take that next bite, and the one after that.
The alternative hypothesis is that as persons with less scent/flavor perception gets less reward per bite, they'll eat more bites to get the same total positive experience. They would therefore gain weight.
My gut says the first hypothesis is correct. Will someone study this please?
