this video is a must watch... youtu.be/Q0rFEbGYnEE
I read the book by Dr David Kessler, The End Of Overeating and it is a 5 star book.
Former head of the FDA goes into fantastic detail how the food industry uses salt, sugar, fat to manipulate your cravings and actually create addiction. The science behind it is un- assailable in my opinion...
The video is a brief overview that explains it pretty well.... worth the watch if you really want to understand how food affects you.
