Hi, I'm Dave Asprey, the father of biohacking. I've lost over 100 pounds of fat in my life, so I know a thing or two about losing weight. But I recently sat down with one of the top weight loss doctors in the world and asked him one question. If you had to lose 50 pounds fast, what would you do?
What he said next is exactly what I would do if I had to lose weight all over again. So in the next few minutes, I'm going to tell you what he told me. Now, there's something you must know about losing 50 pounds.
The reason it's hard to lose weight is likely because your body has a metabolic block. This block is related to insulin. Insulin is the hormone that helps move sugar from your blood into your cells so your body can use it for energy.
But when you eat a lot of sugar too often, your insulin levels remain high. When insulin levels are always high, it starts to become less effective at moving sugar into your cells. It's like a door that won't open anymore, no matter how hard you knock. This block is insulin resistance. This means your body has to pump out more and more insulin just to get the same job done. Now, here's where it actually starts to hurt your fat loss. Insulin doesn't just manage blood sugar. It's also your body's main storage hormone. Whenever insulin is around, it tells your fat cells to store energy instead of releasing it. Think of insulin as a lock on your fat.
When insulin is high, your body has a much harder time burning stored fat for fuel. That lock starts to open when insulin drops back down. But if your insulin is elevated all day long, that lock almost never comes off. Your fat always stays sealed no matter what you do.
Your body stays stuck in storage mode even when you eat less. This is why you feel like you're doing everything right and still can't lose weight. No amount of effort will work if your system is blocked. You can cut calories, grind through cardio and white-knuckle your way through hunger. But as long as insulin keeps that lock on, none of it will work. So what do you do when your body is stuck in storage mode? That's the exact question I put to the doctor. Between the 100 pounds, I've lost myself and a man who wrote a best-selling book on burning fat and healing your metabolism, you'd expect the answer to be complicated. It isn't. He told me he wouldn't cut calories harder and he wouldn't touch a single fat burner. He'd do just three simple things to lower insulin resistance and finally lose weight. The first step is the one most people skip because they think weight loss is only about eating fewer calories, but it's actually about removing the food that keeps your cravings high and your body stuck in storage mode. That is why you must first cut out ultra-processed foods. Ultra-processed foods are not just normal foods with extra calories. They contain added sugars, flavorings, and textures that make them addictive. And because they are usually low in fiber and protein, they do not give your body a strong fullness signal. So even after eating a bunch of calories, your brain keeps searching for more food because your body still feels undernourished. When you constantly eat ultra-processed foods, your blood sugar rises. This is especially true with foods high in refined carbs and added sugar.
Your body responds by releasing insulin, which is normal. The problem starts when you trigger that signal all day from constant snacking. The problem starts when you trigger that signal all day from constant snacking, and when insulin stays high too often, your body has a harder time accessing stored fat. So the first job is to remove the foods that keep pushing insulin up and hunger out of control. Instead of ultra-processed foods, start eating meat, eggs, fish, grass, fed a too dairy and low toxin vegetables and carbs. These foods will improve your blood sugar control and make it easier for insulin to come back down between meals. But cutting out processed food alone is not enough. Because if you're eating all day long, you are still keeping your insulin elevated, you're still keeping that metabolic block in place, and that fat isn't going anywhere. That's why the second step is where most people misunderstand fat loss. Because even after you remove ultra-processed foods, you can still keep your body stuck in storage mode if you are eating all day. Most people think the only thing that matters is what they eat. Because every time food enters your system, insulin rises. Even if the meal is clean, grass-fed, and blessed by a monk on a mountain, insulin still rises. And when insulin is elevated, your body is not in fat burning mode. It is in fuel storage mode. So if you are constantly snacking from morning until night, your fat never gets a clean signal to burn. That is why the second step is not about starving yourself.
