*For anyone who is interested in reading this post, I would also suggest you check out Layne Norton’s dissection of the film in question here. I have also caught wind that Robb Wolf may be doing a live debate with James Wilks which I anticipate being far more useful than the one with Chris Kresser (and James) on the Joe Rogan Experience. Standby.
I recently had dinner with a group of friends, and one friend was discussing taking better care of himself in 2020. One of his anticipated strategies was to take more of a plant-based approach to his diet. When I asked why he thought this would be a practical approach, he brought up the scene in the Gamechangers documentary, where the athletes who ate the high-fat meal before getting their blood drawn and centrifuged showed ‘fatty’ blood after their individual draws. This scene gave my friend a visceral feeling of concern when it comes to the nutrition of animal fat.
This is just one example of the unscientific, propaganda-driven junk that was used as ‘proof’ of the dangers of meat consumption in the documentary.
Without getting into details like the Randle cycle and how triglycerides and glucose compete for energy usage when both are in high demand, we can address this nonsense at a higher level with a simple context.
When you eat fat, fat substrates will end up in your blood- packaged in chylomicrons- which make the blood appear to be ‘cloudy.’ Guess what happens when you eat carbohydrates? Carbohydrate substrates will end up in your blood. Guess what happens when you eat protein? Protein substrates will end up in your blood. When you eat macronutrients, the broken down substrate should end up in your blood. Without it, the food you consumed would have zero nutritional value.
The movie’s producers imply that fatty acids in your blood are a sign of heart disease risk. This is false. In fact, without the metabolism of fat into its various substrates, you would suffer and die. When an unhealthy, overweight person with poor endothelial function overeats any energy source, and that energy source stays chronically elevated in the blood, that is a different story. But even the mechanism that makes that a problem is not what is implied in this video clip. If you notice, there isn’t any test of endothelial function in the ‘look, fat in the blood’ scene; just a context-less visual for shock value. This is the general theme of the entire film.
A plant-based diet may be helpful for you. In most cases, I would disagree that it is optimal, but it comes down to many individual factors. Just don’t be scared into believing animal foods are unhealthy due to scare tactic anecdotes like cloudy blood, 2-day boner studies, and the estimated diets of slave gladiators.
