As a former fatty (now I am just chubby), it was the composition of my diet and NOT the calories that made me fat. It was changing the composition of my diet, and NOT exercise, that finally allowed me to lose weight, reverse my high blood pressure, reverse prediabetes, etc...
Sloth is a SIDE EFFECT of obesity. It is NOT the cause.
Great free lecture here if you are really interested in the science...

As for GMO in the food supply, unless you are growing it yourself, you are eating GMOs in some form. Even something as innocent as vitamin D enriched milk has corn in it. Corn oil is used as a carrier for the vitamin D. Speaking of vitamin D, I take supplements in winter. Found out the one I bought last time uses soy oil ARG!
Not sure about the absorption issue. That wasn't one of my research targets. I would like to see the nutrition text book info.
In general I am not an anti-science person. I am VERY MUCH against the business practices used against farmers, seed cleaners and the general public by Monsanto and others. I don't believe the gmo crops have been properly tested, and I don't believe they can be contained. I also think that things containing gmo should be clearly labeled so individual consumers can decide if they want them or not. The fact that so much effort has gone in to hiding the ingredients tells me A LOT.
So, with all this going on, I just made a seed vault that is going in my deep freeze for long term storage. My garden is expanding and I am switching my ducks and quail to non gmo whole grains and raising as much food as possible. The back yard is already mostly growing beds. I am working on the front yard this year.
