I'm amazed at the few ignorant comments made about this movie. They claim this and that and the movies facts just aren't true. Well this is a perfect example of the brainwashing we have been subjected to for nearly 70 years. Old ideologies are hard to die but the ones whom open their minds and let go of what they were taught will reap the benefits of doing low carb or no carb. These ignorant dufuses throughout their lives have held on to the outdated information and epidemiological studies that of course prove nothing. Great job on this documentary and hopefully there will be one about not only the keto diet but also the tens if not hundreds of thousands of people eating the carnivore diet.
