This is what you would get if Michael Moore wanted to make you go vegan. I think I now count as an endurance athlete, as I made it through this slog, and without even switching to a plant-based diet.
There is some really interesting data at the core of this movie, but it's so wrapped up in garbage, misinformation and hyperbole that it entirely undermines itself.
First, while they were clearly doing everything possible to avoid the word Vegetarian, having every single person in every supposed interview use the exact same phrasing of "a plant-based diet" kind of undermines the authenticity.
The cherry-picking is painful. It goes into how the Roman Gladiators were vegetarian... But not the why (barley helped build up a layer of fat over muscle, which matters a lot if you get hit by bladed weapons professionally. Personally, I'm not training for that).
Nope, instead it's breezing past scientific journals that cross-fade past us with only a few words highlighted and then we're on to absurd claims.
"Two months as a vegan got my battle ropes time from under eight minutes to over an hour!" Uh-huh. Your strength endurance went up more than six times due to giving up meat over a couple months. Sure. Right.
If the claims here were true then the world of professional athletes would be 100% vegetarian, as the filthy meat-eaters could never compete against their vegan superiors. Explains our narrator's triumphant return to MMA after he recovered from his injury, followed by all those championships. Oh, wait.
If you want some interesting reading about sports nutrition, check out the studies referenced in this movie. Some really cool stuff there! If you want dramatic music, cherry-picked examples that consider non-vegetarian, low-carb and ketogenic diets interchangeable (whichever looks worst against vegetarianism!), and a whole lot of you might enjoy this. I sure didn't.
