There are three body types, meso, endo and ecto morphs. Most are somewhere between 2 of those types. Numerically endomorphs are the largest group, at around 50%. If you are even partially endomorphic then you will gain weight easily and lose weight very slowly and with great difficulty. We are seeing more endomorphs now because the invasive immigration for the last 50 years has been from th 3rd world with a high endomorphic population.
High fructose corn syrup. Child obesity, all obesity, skyrocketed after this was added to the food chain.
