“How do we decide what and how much to eat? Maybe satiety consists of different pathways that control different types of nutrients,”<p>This is a pet theory of mine. That, vastly simplifying, our bodies try to make us eat until we have a sufficient amount of whatever number of elements they need to function. The more varied you eat, the less you need to eat, conversely, the more homogeneous your sources of food (bread, rice...), the more you'll need to eat to try to get what is hardly there.<p>I have no idea whether this idea is mainstream between researchers but it always seemed to me as feasible as a satiety mechanism as just counting calories, and it explained quite well the observations I've made about myself. Anybody here could point to the current state of the art in the field ?
I've got a real sweet tooth and excessively eat sweet things.<p>I also have a 23andMe account and looked up to see if I have the FGF21 gene?<p>I found that I have 2 SNP's on gene FGF21.<p><a href="http://i.imgur.com/qnRD5M4.png" rel="nofollow">http://i.imgur.com/qnRD5M4.png</a><p>Any idea what this means relative to the study?
