Joe Cross wasn’t just overweight when he started filming. He was dying. Or at least, it felt that way. He was carrying an extra hundred pounds, his skin was erupting in hives from an autoimmune disorder called chronic urticaria, and he was popping Prednisone like it was candy. He looked in the mirror and saw a man who had reached the end of his rope. So, he did something that most doctors at the time thought was absolutely insane: he stopped eating solid food for 60 days.
That journey became Fat Sick and Nearly Dead. It wasn't just a documentary; it sparked a global obsession with masticating juicers and green drinks that smelled like a lawnmower’s bag.
The Raw Reality of the Juice Fast
Let’s be real for a second. Drinking nothing but kale, cucumber, and apple juice for two months is brutal. It’s not "cleansing" in the spiritual sense; it’s a physical overhaul that forces your body to find energy elsewhere. Joe Cross traveled across the United States, tethered to a juicer in the back of his car, meeting people who were just as broken as he was. The most famous of these was Phil Staples, a truck driver who weighed over 400 pounds and suffered from the same rare skin condition.
Phil's transformation was arguably more impactful than Joe's. Why? Because Phil was the "everyman." He didn't have Joe's resources initially. Watching a man who could barely walk start to reclaim his life by sipping "Mean Green" juice was a cultural reset. It moved juicing from the fringes of hippie culture into the mainstream kitchens of suburban America.
But what actually happens to your body when you go Fat Sick and Nearly Dead style?
You lose weight. A lot of it. Joe lost 100 pounds. Phil lost even more. But the science behind why it works—and why it’s dangerous—is more complex than the film makes it out to look. When you stop eating fiber, your digestive system goes into a sort of standby mode. You're getting a massive hit of micronutrients, sure, but you're also missing out on essential proteins and fats. It’s a crash course in caloric restriction.
What the Documentary Got Right (and Wrong)
Joe Cross was right about one big thing: the "Standard American Diet" is killing us. Processed sugars, lack of micronutrients, and an over-reliance on "dead" food lead to the very inflammation that caused his hives. By flooding his system with plant-based enzymes and vitamins, he essentially flipped a metabolic switch. He gave his body a break from the constant inflammatory load of junk food.

However, the film leans heavily on the "detox" narrative. Modern science is a bit more skeptical about that word. Your liver and kidneys are already detoxing you 24/7. What Joe did wasn't necessarily "flushing toxins" in the way a plumber flushes a pipe. Instead, he was providing his body with the tools it needed—specifically antioxidants and phytonutrients—to heal itself while simultaneously removing the triggers (processed flours, sugars, and dairy) that kept him sick.
It's also worth noting that Joe had medical supervision. Dr. Joel Fuhrman, a well-known physician and author of Eat to Live, was a key figure in the background. Most people watching at home didn't have a world-class nutritionist on speed dial. This is where the Fat Sick and Nearly Dead movement got a bit messy. People started doing these fasts without checking their electrolyte levels or considering their underlying health issues.
The Legend of the Mean Green Juice
If you've seen the film, you know the recipe. It’s basically the protagonist of the whole story.
- 1 Bunch of Kale
- 1 Cucumber
- 2 Celery Stalks
- 1 Green Apple
- 1/2 Lemon
- 1 Thumb of Ginger
It tastes... green. It’s tart, a bit spicy from the ginger, and undeniably earthy. The brilliance of this specific juice is the balance. The cucumber and celery provide massive hydration. The lemon and ginger cut through the bitterness of the kale. The apple provides just enough sugar to make it drinkable without causing a massive insulin spike.
But let’s talk about the fiber. This is the biggest criticism of the Fat Sick and Nearly Dead approach. When you juice, you throw away the pulp. That pulp is the insoluble fiber your gut microbiome craves. Without it, the sugar in the juice hits your bloodstream faster. While Joe’s results were undeniable, modern nutritionists often suggest blending (smoothies) instead of juicing to keep that fiber intact. Or, at the very least, using juicing as a supplement to a whole-food diet rather than a total replacement.
Why We Are Still Talking About It 15 Years Later
The documentary came out in 2010. Since then, we’ve seen a million health trends come and go. Keto, Paleo, Carnivore, Intermittent Fasting. Yet, Joe Cross remains a staple in the wellness world. Why?

Honestly, it’s the human element. The film didn't feel like a lecture. It felt like a road trip. Joe was likable. He was honest about how much he missed pizza. He didn't pretend it was easy. When he met Phil Staples at a truck stop, it wasn't a staged "Loser" style weigh-in. It was a genuine moment of connection between two men who were literally eating themselves to death.
Phil's story in the sequel, Fat Sick and Nearly Dead 2, added a layer of much-needed nuance. It showed that staying healthy is a lot harder than getting healthy. Phil struggled. He gained some weight back. He had to figure out how to live in a world that sells cheap calories at every corner. That's the part the first movie glossed over: the "forever" part.
The Risks Nobody Mentions
You can’t talk about being Fat Sick and Nearly Dead without mentioning the dark side of extreme fasting.
- Muscle Loss: When you don't eat protein for 60 days, your body might start breaking down muscle tissue for amino acids.
- Gallstones: Rapid weight loss can cause the liver to secrete extra cholesterol into bile, leading to stones.
- Nutrient Deficiencies: You might get plenty of Vitamin C, but you’re getting almost zero Vitamin B12, Vitamin D, or Omega-3 fatty acids on a juice-only diet.
- Disordered Eating: For some, extreme "cleanses" can trigger a cycle of bingeing and purging behaviors.
It’s a "nuclear option." Joe used it because he was in a nuclear situation. If you just want to lose five pounds for a wedding, drinking nothing but green juice for a month is probably overkill—and potentially counterproductive.
Practical Steps for the Modern Human
You don't have to go 60 days without chewing to see results. The legacy of Joe Cross is really about the power of plants. If you want to take the spirit of the film and apply it to a normal life, here is how you actually do it without losing your mind.
Start with the "One Juice a Day" rule. Instead of replacing all your meals, just replace one. Or, better yet, drink a green juice before your regular breakfast. It crowds out the junk. You’ll find you’re less hungry for that second bagel because your cells are actually getting the nutrients they need.

Focus on the micronutrient density. The whole point of Fat Sick and Nearly Dead was moving the needle from "calorie dense" to "nutrient dense." Look at your plate. If everything is beige (bread, meat, pasta), you’re doing it wrong. Add color. Purple cabbage, deep orange carrots, dark leafy greens.
Don't ignore the protein. If you are going to do a short juice "reboot" (maybe 3 to 5 days), consider adding a clean pea protein or collagen powder to at least one drink. Your muscles will thank you, and you won't feel like a zombie by 3:00 PM.
Check your bloodwork. Joe had doctors monitoring his progress. If you’re planning on a radical diet shift, get a baseline. Check your C-Reactive Protein (a marker for inflammation) and your fasting insulin. See where you are. Then, after a month of adding more plants, check again. The data doesn't lie.
Understand the "Why." Joe Cross didn't just want to be thin. He wanted to be off medication. He wanted to stop itching. He wanted to live. If your only goal is a number on a scale, you’ll likely fail when the juice starts tasting like dirt. Find a "why" that is tied to your quality of life, not just your pants size.
The reality is that most of us are a little bit fat, a little bit sick, and hopefully nowhere near dead. But we are trending in the wrong direction. The "Mean Green" isn't a magic potion, but it is a potent reminder that what we put in our mouths is either medicine or poison. Joe Cross chose medicine. He’s still healthy today, still juicing, and still reminding people that your body has an incredible capacity to heal if you just stop getting in its way.
Actionable Takeaways for Your Health Journey
- Buy a Juicer (But Use It Wisely): Masticating juicers are better than centrifugal ones because they don't heat up the juice, preserving more enzymes. But don't let it become a coat rack.
- The 80/20 Rule: You don't need to be 100% juice. Aim for 80% whole, plant-based foods and 20% whatever else you enjoy. This is sustainable; a 60-day fast is not.
- Watch the Sugar: Even "natural" juice from fruit is high in fructose. Keep your juice ratio at 4 parts vegetable to 1 part fruit.
- Walk: Joe didn't just juice; he walked. Movement is essential for lymphatic drainage, which helps your body process the changes it's going through.
- Community Matters: Joe had Phil. Phil had Joe. Don't try to overhaul your health in a vacuum. Find a group, a friend, or an online community to keep you grounded when the cravings hit.
- Transition Carefully: If you do a juice fast, the first meal back shouldn't be a cheeseburger. Start with watermelon or a light salad. Your stomach needs time to wake up.
