Gary Taubes' Good Calories, Bad Calories was the book that convinced me to go low carb, the cancer chapter in particular. Why We Get Fat came out after and is excellent, what I still recommend almost a decade later. That shorter book has Dr Westman's Diet right in the back, super simple how to eat LC. https://www.dietdoctor.com/se/wp-co...starch_diet.pdf

But the cancer info was cut from the short version, so depends on your tolerance for many studies. The first time his work made an impact was in 2004, cover of the NYT Magazine, What if it all is a Big Fat Lie? http://garytaubes.com/works/

The Fat Fiction Movie is good if you haven’t seen this type of documentary before, there are other ones available on DietDoctor And Netflix that cover the same ground. This one seemed to have a good budget and was well done technically.
