I, too, think there are other factors in addition to calories consumed and calories burned.

There are many, many external endocrine disruptors now. Arielle mentioned the BPAS, and hormone disruptors in plastic. Those hormone disruptors are also in the flame retardants in upholstery.

And there are the massive EMFs. Dr. Samuel Milham published a book called, Dirty Electricity, showing the differences in cases of serious diseases between those who use electricity and those who don't, such as the Old Order Amish.

The way cattle and crops are raised and processed now is drastically different.

To me, this situation points to eating the cleanest food we can manage.

I don't remember snacking being a norm in the 80s. At least not with the people I know. For me, this came after 2000. Now, it seems people just eat whatever they choose, whenever they choose.

Eating regular meals, and not munching on that and that between meals, seems to be swimming upstream. Perhaps it's just who I notice.
