The documentary begins with the narration by James Wilks, a combative expert teaching fighting techniques to U.S Marines, U.S. Marshals, Navy and SWAT teams. He also won a UFC. He got injured (tore ligaments in both of the knees) at a point when he was sparring for heavy weight championship and was rested to bed for 6 months. He used this time to do study on peer reviewed science for research on nutrition and recovery. He then found/discovered some of the things:
The Gladiator Graveyard (Ephesus, Turkey) is the only one with a significant no of individuals buried there. Archeologists recovered the remains of at least 68 gladiators. There have been more than 5000 bones analyzed for this study. It was found that in the cross section of the bone there is high bone mineral density which indicated intense training and high-quality diet to build up strong muscles and strong bones. This diet gave the gladiators, a nick name Hordeari which means “beans and barley muncher”. Different food sources give different amounts of strontium in the bones. Highest strontium levels in vegetarians and lowest strontium levels in carnivores. The gladiators were predominantly vegetarian. This study blew James mind. Even in the UFC, in one of the greatest fight against Conor McGregor vs Nate Diaz. McGregor was a big meat eater, he eats steak all day. Diaz was on a plant based diet. There were several other plant based athletes.
Dr. James Loomis, a team physician (St Louis Rams/Cardinals) who was part of two championships, a world series and a super bowl said that several people has a perception that protein is what sustains the energy. The actual energy for exercise mainly comes from carbohydrates in the form of glycogen that we store in our muscles. And when we sacrifice those carbohydrate calories for protein calories in our diet what ends up happening is you will develop a glycogen depletion which leads to chronic fatigue and loss of stamina.
Proteins are strings of amino acids, there’s some amino acids that our bodies cannot make so we have to get them from food. One of the misconception is that plan-based diet is inferior to animal-based as they can’t get all amino acids from plants. Event single plant contains all amino acids in varying proportions. As long as the proper amount of amino acids are consumed the source is irrelevant.
Vegan is no meat, no milk and no eggs.
Some of the points mentioned in the documentary like: When I stopped eating meat, I became more stronger and bigger is absolutely absurd.
An experiment was conducted by Dr. Robert Vogel, co-chair of the NFL’s subcommittee on cardiovascular health. The endothelium is a lining of blood vessels, it regulates blood flow throughout the body. It knows that a particular muscle group or organ needs more blood flow, and it dilates, it opens up. When the endothelium is impaired it cannot open up, it cannot allow blood flow to increase as much. So the experiment is:
The test subjects three football players from Miami Dolphins. One day there were fed with three burrito breakfasts with lot of protein. Two of them have sources of animal-based protein and fat. One is from beef, one is from chicken. Third is a plant-based burrito which has beans in it, so the protein and fat came from a plant-based source. And the next day all those three were fed with plant-based burritos. Two hours after each meal the players had their blood drawn and put into a centrifuge. The red blood cells sinked to bottom and an amber colored fluid called plasma rises to the top. If the plasma is see through then it means there is not much fat in the blood and the endothelium is likely functioning well.

Looking at the above picture that shows what circulates in their bloodstream. At the top is fat circulating in the blood (the one that is cloudy from meat burrito). For the vegan guy, the blood is nice and clean
The Dr said that sources of animal-based protein and fat have tremendous impact on endothelial function that lasts for six or seven hours after you eat. So if you have bacon and eggs for breakfast, hamburger for lunch, and a steak for dinner. If this is going on all day long your blood will always be cloudy. And the ability to operate at your best is always impaired. Dr. Vogels experiment was backed up by numerous studies measuring how a single animal-based meal can impair blood flow. There is also a large body of research that showing plants have the opposite effect, improving endothelial function and increasing blood flow.
Controlled studies show that simply drinking beet root juice before training allows subjects to cycle 22% longer and bench press 19% more than the total weight. Getting enough energy and protein from meal is one thing but seeing a single-animal based meal would do to the bloodstream sealed the deal and proves plant-based diet is better.
Dr. Scott Stall, a former olympian and a team physician for the USA olympics team said the below:
In animal products we are getting protein packaged with inflammatory molecules like Neu5Gc, endotoxins and heme iron. The study that showed that single hamburger impairs blood flow also showed that it can increase measures of inflammation by 70%. In the arteries, inflammation reduces blood flow. In the muscles and joints it can increase soreness and delay recovery. On the other hand in plant based products we are getting protein that’s packaged with antioxidants, phytochemicals, minerals and vitamins that are gonna reduce inflammation and helping to optimize blood supply and body’s performance. The antioxidants that Dr. Stall is talking about are found entirely in plants which have 64% antioxidant content of animal foods. Even iceberg lettuce has more antioxidant content than salmon or eggs. As a result switching to a plant-based diet reduces the measures of inflammation by 20% in just three weeks.
When you eat animal foods you start to form plaques in the coronary arteries. Plaque formation in the arteries doesn’t just limit the function of arteries it can also block the blood flow and that’s when the heart starts to having some real problems. For nearly 50 years we were told that the primary causes of heart disease was saturated fat and cholesterol. The research now also shows that other inflammatory compounds in animal based foods like those that can impair athletic recovery also play a significant role in the development of heart disease.
Studies found that Heme iron which comes from animal protein (red meat, poultry, seafood, fish) is one of the cause for coronary heart disease (CHD). According to that one milligram of heme iron a day is associated with 27% increase in risk of CHD. To put that in perspective an average hamburger patty has about two to three milligrams heme iron. And it isn’t just the iron that causes heart problems, it’s actually the animal protein itself. When the protein found in animal food is cooked, preserved or even digested by our gut bacteria highly inflammatory compounds are formed that corrode our cardiovascular system. This helps explain people who get all of their protein from plants reduce their risk of heart disease by 55%.
The studies also found that patients with CHD after started taking animal foods, there is good blood flow, the heart pumps blood more normally. After a year, even severely clogged coronary arteries became measurably less clogged and even more improvement after five years. On the contrary who are eating red meat, seafood, poultry and doing less exercise their arteries got more clogged after one year and even more clogged after five years. It is also said that there is accumulating evidence that high consumption of proteins from diary sources is related to a higher risk of prostate cancer.
Arnold Schwarzenegger said he ingests 250 grams of protein a day as he weights 250 pounds. He said after changing to plant-based diet his cholesterol went down to lowest.
Everyone kept warning that you could only get B12 vitamin from animal foods. But it turns out B12 isn’t made by animals after all. It’s made by bacteria that these animals consume in the soil and water. Before industrial farming, farm animals and humans could get B12 by eating traces of dirt on plant foods or by drinking water from rivers or streams. But now because of pesticides, antibiotics and chlorine they kill the bacteria that produces this vitamin. Even farm animals have to be given B12 supplements. And up to 39% of people tested, including meat eaters are low in B12. As a result the best way for humans to get enough B12, whether they eat animal foods or not is simply to take a B12 supplement.
One doctor conducted a experiment on three athletes and proved that those who eat more meat on a regular basis loose manhood and might not get erections after sometime. Where for those on plant-based diet erections happens more often it seems 😛
Conclusion:
To sum up, it seems the objective or purpose of the documentary to to emphasize that animal based diet is not superior than plant-based and it is just a misconception. Have said it above, As long as the proper amount of amino acids are consumed the source is irrelevant.
The documentary also emphasized about the following:
- It also wants to prove that animal based foods impairs the blood flow by effecting the endothelial function. The blood test with the Miami Dolphins NFL players measure how a single meal could affect blood flow through the entire body.
- Animal food increases inflammation and delays the recovery process.
- Ingestion of animal protein increases the risk of heart problems as it has heme iron in it. (They explicitly stated that animal food increases the risk of heart attacks).
- Switching from animal-based diet to plant-based diet reduces the risk of high blood pressure and heart problems.
- One doctor also said that the scientific study shows the more meat men eat the more quickly they loose manly manhood.
