I saw this documentary last night: https://www.pbs.org/wgbh/blood-sugar-rising/
Maybe you watched it too. When trying to build muscle, we eat a lot of carbs, like 2x body weight in grams or more, supposedly the good carbs like potatoes and rice most of the time. And we use that glucose for energy, it doesn't go to our waist line. I get all that. But has any research been done about active bodybuilder types developing type 2 later in life?
