WHY DO I FEEL HUNGRY ALL THE TIME?
For those of us who have tried dieting, the experience of rebounding weight gain is all too common. Dieting typically comes with an insatiable hunger that often leaves us wondering: “Why am I constantly hungry?”
YOUR GENETIC EXPRESSION CAN MAKE FEEL HUNGRY ALL THE TIME
The article on Epigenetics of Nutrition explained the mechanism by which our environment influences epigenetic changes in our DNA. The composition of nutrients in diet can work to activate and deactivate genes in our DNA at the molecular level. It can influence the activities of enzymes, and it can even turn off genes that promote aging.
It makes sense from an evolutionary viewpoint that intermittent fasting would prolong life. Our ancestors survived famines and long-term food shortages by epigenetic changes that promoted longer lifespan and retarded their reproductive systems.
The genetic expression of aging genes is not only related to epigenetic modifications. It works across generations when natural evolutionary forces decide who survives and who does not. When food is abundant, natural selection favors fertile women with shorter lifespans. When food is scarce, natural selection favors women with longer lifespans.
As James Holland Jones put it: “High fertility increases the selective premium placed on early survivorship, while high life expectancy at birth decreases it.”
POVERTY AND OBESITY
As Gary Taubes repeatedly points out in his book, The Diet Delusion, obesity is most common amongst the poorest in society. Moreover, evidence shows that this group does not have a READ MORE.
