Honestly, it’s been over a decade since it first dropped, but the conversation hasn’t really slowed down. People are still debating it. If you decide to watch Forks Over Knives documentary, you aren't just sitting down for a movie; you’re basically walking into a giant, high-stakes science lecture that tries to convince you that your dinner is killing you.
It sounds dramatic. It is dramatic.
The film focuses on a pretty radical idea: most of the "diseases of affluence" like type 2 diabetes, heart disease, and even several types of cancer can be prevented—and sometimes even reversed—just by ditching animal products and processed oils. We’re talking about a Whole Food Plant-Based (WFPB) diet. It’s not just "being vegan" for the animals; it’s a specific nutritional approach focused on health outcomes.
The Men Behind the Science: Campbell and Esselstyn
The heart of the film follows two researchers who didn't even know each other at first. T. Colin Campbell, PhD, a nutritional biochemist from Cornell, and Dr. Caldwell Esselstyn, a top surgeon at the Cleveland Clinic.
Campbell grew up on a dairy farm. He literally grew up thinking milk was the perfect food. But then he went to the Philippines to solve a childhood malnutrition problem and noticed something weird. The wealthiest kids, the ones eating the most meat and dairy, were the ones getting liver cancer. It didn't make sense. Later, he led "The China Study," which is often cited as one of the most comprehensive studies of health and nutrition ever conducted. He found a massive correlation between animal protein consumption and chronic disease.
On the other side, you have Esselstyn. He was a surgeon seeing people with advanced heart disease. He realized he was just putting "band-aids" on a problem that was fundamentally caused by what people were putting in their mouths. He took a group of patients—people who were essentially told they were going to die soon—and put them on a strict plant-based diet.

Why People Still Watch Forks Over Knives Documentary Today
The world has changed a lot since 2011. Back then, finding almond milk was a mission. Now, it’s everywhere. But the reason people still watch Forks Over Knives documentary is that our health crisis hasn't gone away. If anything, it’s worse.
It’s Not About Moderation
The film is controversial because it rejects the idea of "everything in moderation." It argues that if you have heart disease, eating "a little bit" of the stuff that caused it is like smoking "a little bit" of cigarettes while you have lung cancer.
- It challenges the USDA food pyramid.
- it looks at the influence of the dairy and meat lobbies on government guidelines.
- It features real people—not just actors—reversing their meds in weeks.
One of the most striking parts of the film is seeing patients like Ruth Heidrich, who was diagnosed with stage IV breast cancer and transitioned to a plant-based diet. Or Joey Aucoin, a guy who was on a cocktail of pills for cholesterol and blood pressure and managed to get off almost all of them just by changing his plate. It feels real because it is real.
The Nuance: Is It All 100% True?
Look, no documentary is without its critics. If you’re going to watch Forks Over Knives documentary, you should also know the counter-arguments. Critics often point out that the film (and Campbell’s China Study) focuses heavily on correlations. Just because two things happen at the same time doesn't always mean one caused the other.

Some nutritionists argue that the film demonizes all animal products a bit too much and doesn't give enough credit to the dangers of sugar and highly refined seed oils independent of meat. Others say the diet is too restrictive for the average person to maintain long-term.
But even the skeptics usually admit one thing: Americans eat way too much processed junk and not nearly enough fiber or vegetables. Even if you don't go 100% plant-based, the core message of "eat more plants, less processed stuff" is basically bulletproof in the medical community now.
The Western Diet vs. The Rest of the World
The film does a great job of showing the "natural experiment" that happened during World War II. In Norway, when the Germans confiscated all the livestock to feed their troops, the Norwegians were forced to eat plants. The rate of death from circulatory diseases plummeted. As soon as the war ended and they went back to eating meat? The rates shot right back up.
It’s hard to ignore data like that.
Actionable Steps After You Watch
If you’ve seen the film or are planning to, don't just feel guilty about the burger you ate for lunch. The goal of the documentary is empowerment. Here is how you actually apply what the film teaches without losing your mind:

- Focus on the "Whole" part. If you replace steak with Oreos, you’re vegan, but you aren't healthy. The film emphasizes "whole foods"—potatoes, beans, brown rice, greens.
- Don't do it alone. The "Forks Over Knives" brand has grown into a massive ecosystem. They have a meal planner app, a magazine, and a bunch of cookbooks. It's way easier to stick to a diet when you actually know how to cook a bean chili that doesn't taste like cardboard.
- Check your numbers. If you decide to try this, get a blood test first. Check your cholesterol and A1C. Then try it for three weeks. The film claims you’ll see changes in 21 days. Test it yourself.
- Learn the "Wet" vs. "Dry" cooking method. One of the biggest takeaways from the film's chefs is sautéing with water or broth instead of oil. Oil is pure fat and incredibly calorie-dense. Cutting it out is the fastest way to drop weight according to the film's logic.
The Long-Term Impact
The documentary really sparked a movement. It paved the way for newer films like The Game Changers or What the Health, but Forks Over Knives remains the "OG" because it sticks mostly to the medical and scientific side rather than just the "bro-science" of athletics or the pure shock value of animal cruelty.
It’s about you. It’s about your heart. It’s about why your grandfather might have had a stroke and how you can avoid that same path.
Ultimately, watching the film is a bit of a wake-up call. You might not agree with everything Dr. Campbell says. You might think Dr. Esselstyn is a bit too intense. But you’ll never look at a glass of milk or a piece of cheese the same way again.
Final Practical Advice
Start small. You don't have to clear out your pantry tonight. Try "Meatless Mondays." Then try "Plant-based until 6 PM." The film shows that even significant shifts toward plants can have a massive impact on your energy levels and long-term health markers.
Next Steps for Your Health Journey:
- Visit the official Forks Over Knives website to find their "Beginner’s Guide."
- Download a plant-based recipe app to find at least three "go-to" meals that don't involve meat.
- Consult with a plant-based friendly doctor or nutritionist if you are currently on medication for blood pressure or diabetes, as your dosages might need to be adjusted quickly once you change your diet.
