Back in 1999, I was a brand new millionaire in Silicon Valley. But I was dying. Literally. I weighed 300 pounds and my doctor told me I was heading straight for a heart attack or stroke and I was only 30 years old. So for the next year and a half I hit the gym six days a week, ate a low calorie diet and even tried going vegan for 18 long and dark months. Nothing worked. The fat wouldn't budge. I could lose half of it and then it would come back with a vengeance. And then I drank a cup of something very, very strange at the top of a mountain on a spiritual pilgrimage. One sip flipped a switch in my brain that turned it on in a way I have never felt before. And when I started doing it regularly, it helped me drop 100 pounds of fat. And I still have abs to this day. Now you're probably wondering what the hell I drank. I still remember it like it was yesterday. I'm at 18,300ft up in the mountains of Tibet, in the middle of a high altitude trekking journey at Mount Kailash, the holiest mountain in the world. And I was sitting in a guest house, frozen to my core and still overweight, when a tiny Tibetan woman hands me this creamy cup of yak butter tea. I'd never seen anything like it. It was thick, golden, kind of oily. I took one sip and about 30 seconds later, my brain started tingling. I felt it in my entire body and my brain had not been working very well, for a long time, and I'm at high altitude. I shouldn't be feeling like I can snap awake, but I did. And the exhaustion that I've been dragging around just broke. And for the first time in years, especially at high altitude, I felt like dancing. I actually felt alive. And the crazy part is, I had never seen this drink before. Nobody in America talks about it. Not one doctor, not one trainer, not even diet books. And when I got home, I couldn't stop thinking about it. So I started experimenting. I swapped the tea for coffee and then mold free coffee and the yak butter with grass fed butter. I tried hundreds of different combinations to figure out did coffee or tea or the butter make the difference. And when I dialed it in, it crushed my cravings and it kept me energized for the entire day. I just didn't want to eat because my brain worked well, my body worked well, and I was burning fat for energy. And then quickly, the weight just dropped off with no pain, no suffering, no willpower. And here's where it gets weird. I stopped living at the gym. I started eating more food, not less. I quit being a vegan and added meat back in and the fat still kept melting off. And then I ended up achieving it. I lost the full hundred pounds I've been working on losing for more than a decade. I knew I had something special, so I decided to call it bulletproof coffee. Because I literally felt bulletproof when I drank it. I started sharing the story with this butter coffee online to anyone who would listen. And in a matter of months, CEOs in Silicon Valley were drinking it. Magazines like Vogue were writing about it. Even celebrities were swearing by it on national tv. Jimmy Fallon and Shailene Woodley were talking about bulletproof coffee. And I didn't know either one of them, and I didn't pay them to do it, because it works. And within a few years, millions of people across more than 60 countries were blending butter into their coffee every morning. There was even a global shortage of grass fed butter so severe that a Norwegian man was arrested for smuggling grass fed butter into Sweden for Christmas cookies. I wrote a book about putting butter in coffee and longevity that hit the New York Times bestseller list. And I launched a podcast that has over half a billion downloads. That cup of yak butter tea in Tibet changed everything for me. But it was only the beginning. It led me down a path that proved that nearly everything people teach about weight loss and living longer, it's just wrong. Because I tried the stuff that was supposed to work and it didn't work. And there are good reasons, and we know those. Thanks to longevity and biohacking. I learned why diets don't work, why I kept losing weight and then gaining it right back. Why more exercise can make you fatter, not thinner. And what controls fat burning at the cellular level. But the breakthrough that led me to lose those hundred pounds, understanding the truth, is about fat itself. Growing up, everyone around me told me the same story. If you eat fat, you'll get fat. Doctors, diet books, even school posters told me, fat makes you fat. And like most people, I believed it. I counted my calories, I avoided butter, and I bought low fat foods because the experts told me they were healthy. But I couldn't lose the weight, and I felt stuck in a body I didn't want. I even exercised six days a week. It didn't make a difference. I just got hungrier and the weight wouldn't budge. But when I started eating more fat, the right kinds of fat, the same kind of fat that was in that yak butter tea, I noticed something shocking. Instead of getting fatter, my body flipped into fat burning mode. And that's when I realized that avoiding fat kept me overweight all those years, because the right kind of fat kept me from being hungry. And this was just the first piece of the puzzle. When I gave my body the right fats, I had energy all day. Without the roller coaster of highs and lows from carbs, I didn't just feel more alert. I felt in control. My energy went way up, my hunger went way down, and the weight finally just started coming off. My brain ran better, my focus lasted longer, and I didn't hit that 3pm crash that used to just ruin my days. Your brain, it's mostly fat, and it burns fat as one of its main fuels when it can. And good fats support your hormones, like your testosterone is made out of saturated fat, and it keeps your metabolism running. And good fats give you steady energy. But on the other hand, people will tell you carbs are energy. And I did believe that for decades. Eat your oatmeal for breakfast. Grab an energy bar when you're tired. Slam a sports drink full of sugar before your workout. But that energy, it's just a sugar spike and you get a quick burst. And then the crash hits and your brain goes foggy. Your cravings come back even harder, and you get hungry again fast. So you eat more and the cycle traps you. That's what had happened to me. I kept feeding my body sugar and refined carbs because they're low fat and I thought I was fueling myself. In reality, I was running on fumes when I had a full tank sitting right there around my waist. But fat. Fat is different. It is stable. It is clean, long burning fuel when it's the right kind of fat. No spikes, no crashes, just steady energy that lasts. And once I made that switch, my body started burning the fat that I'd been carrying for years. So if you want to try this yourself, start your morning by blending mold free coffee with a tablespoon of grass fed butter and a tablespoon of MCT oil, no sugar. You'll notice a difference in how long your focus lasts and how good you feel. I lost 100 pounds by eating more fat than the government ever recommended. Here's how you can use this in your own life. First, stop fearing all fats. There's a huge difference between good fats and bad fats. Good fats are things like grass fed butter, MCT oil, coconut oil and the natural fats in grass fed meat. Bad fats are things like processed vegetable and seed oils and anything hydrogenated or trans fats. So step one Swap out the bad fats in your kitchen. Replace vegetable oil with butter or ghee or grass fed beef tallow. Step two is you add good fats to your meals. Start small. Blend some butter or MCT oil and your coffee. In the morning, drizzle some extra virgin olive oil on your salad with or cook your eggs in ghee. Do it consistently and you'll train your body to expect good fats that it can actually use to build healthy cells and burn for fuel. And that's when the real fat loss starts. Not from starving yourself, not from low fat foods, but by feeding yourself in the right way. But even after I discovered the power of fat, I was still stuck in one old belief that if I could just eat less calories and I could just work out harder, the fat would melt away. Back then I thought I was doing everything right. I counted every single calorie, I tracked every meal and I spent 90 minutes a day in the gym, six days a week for 18 months straight. I got stronger. But the mirror told a different story. So did my belt. 46 inch waist when I started. 46 inch waist after 18 months of low fat, low calorie overtraining. No matter how hard I worked, the fat wouldn't come off. I felt like I was trapped in a broken system, fighting my own body with no way out and just using my willpower every single day. Just say no to food to just get on the treadmill, to just pick up more weight. It didn't work. And that's when I realized the calories in, calories out rule was just a straight up lie. The formula doesn't explain what's really going on inside your body. That model ignores the bigger players, hormones, metabolism, and inflammation. So it wasn't just about the numbers on a label. Two foods with the same calorie count could act completely differently when I ate them. So I learned it wasn't the quantity of food that controlled fat loss. It was the quality. Nutrient dense foods can send powerful signals to my body and flip my metabolism from storing fat to burning it. And when you eat the right nutrient dense foods, you're giving your body the raw materials to run its engine. And vitamins and minerals and high quality proteins send a we're safe and we have enough energy signal. And when that signal's on, your metabolism doesn't have to cling to every calorie. It can release stored fat for energy. And those same nutrients, they can also calm inflammation. A lot of people think that inflammation is just soreness, but it's a constant chemical alarm that your body sets off when it's under attack from processed oils and sugar spikes and toxins. And that alarm breaks two different critical hormones that can control how you feel and how much you think about food every single day. It's insulin and leptin. When your insulin is always elevated, your fat cells stay locked in. Your body can't access stored energy. And when leptin stops working, your brain never gets a message that you're full. So you stay hungry no matter how much you eat. And when inflammation drops, insulin and leptin start to do their job again. Insulin stops locking fat away. And leptin can finally signal you're full. And that's why when I finally ate the right foods, my hunger just naturally changed. My brain wasn't starving for nutrients anymore. My hormones started working properly again. My appetite just adjusted on its own. And I didn't think about tacos all the time. No more constant willpower battles. My body was finally working with me instead of against me. And feeling lots of energy and being lean just came naturally and effortlessly. And here's how you can make this shift for yourself. Stop obsessing over counting calories and start asking, is this food nutrient dense? Does it have enough protein? Does it have the right kinds of fat? That matters way more than calories. And fill your plate with foods that come from nature. Grass fed meats wild caught low mercury, seafood Organic, low tox and vegetables cut out processed foods that drive inflammation and mess with your hormones. When you eat better quality, you notice you don't need to snack as much. In fact, you won't even think about food for four or five hours after you have a meal. When the meal has enough good fat in it, your metabolism will run hotter, your hunger calms down, and losing weight just starts to feel natural. There's no forcing, there's no effort. It just falls off. But there was another mistake that I was making with my food. I believe the advice that said, eat six small meals a day to keep your metabolism running. Otherwise they go into starvation mode. I thought grazing all day was was the secret. Every few hours I'd grab a snack or a little bit of protein, thinking I was keeping my metabolism all fired up. But instead of getting leaner, I was stuck. My energy dipped. Cravings never went away and I just couldn't burn the fat no matter what I did. So I tried something different. I started skipping breakfast. From the time I went to bed until my first meal the next day, I just wouldn't eat for about 16 hours. It's called intermittent fasting. And at first it felt strange. For years people had said breakfast is the most important meal of the day. But by starting intermittent fasting, I finally gave my body a break. And my system could switch from burning sugar to burning stored fat. That's fat burning mode. And I wrote the first major New York Times bestseller to talk about intermittent fasting because it works so well. And when you give your system a real break like that, something amazing happens in it's called autophagy. This is your body's built in cleaning program. It starts recycling damaged parts of your cells and it makes your metabolism run even better than it did before. And as a result, my hunger calmed down, my energy stopped spiking and crashing, and I lost weight without feeling like I was starving myself. Here's how you can try it. You have that same coffee with butter and some MCT oil blended in in the morning. And that keeps your hunger away. And it keeps your body in fat burning mode. And it won't break an intermittent fast. Because of biochemistry, your insulin doesn't change and some other hormones don't change. So this is a hack for fasting. And then you eat your first real meal at lunch and your second meal at dinner, and that's it. Two meals. No constant grazing, no hunger, no energy crash, no thinking about food. You're just done. It's effortless and it saves you time anyway. When you do this consistently, your body learns to tap into stored fat for energy, your appetite naturally drops, and your weight loss just stops being a fight. So for me, the fat was coming off. My hunger was under control. My energy was steady for the first time in many years. But I still wasn't losing weight as fast as I could have been. Something was blocking it. And I finally found the problem. I was exercising wrong. For years, I thought the answer was simple. Run more or walk more. Sweat more, Burn more fat, lift more. So every day, I would punish myself. Long cardio sessions, 45 minutes on a treadmill at a slope, chasing the idea that every mile on the treadmill would burn fat. But the harder I went, the worse things got.
