Carbohydrates: The Good, the Bad, and the Biohacking
In the world of nutrition, few food groups have been as maligned as carbohydrates. For decades, they've been blamed for a litany of health issues, from obesity and diabetes to heart disease and digestive woes. But what if the real problem isn't carbs themselves, but how we eat them? Enter Dave Asprey, the founder of the biohacking movement, who argues that carbs shouldn't be public enemy number one. In fact, he eats them freely, with a few clever rules.
The Anti-Carb Movement
The anti-carb movement took off in the 1970s, thanks to Dr. Robert Atkins and his popularization of the idea that restricting carbs could push the body into ketosis, a metabolic state where fat is burned for fuel instead of glucose. This philosophy roared back in the 1990s and remained a staple well into the new millennium, with Asprey championing a high-fat, low-carb diet he dubbed the "Bulletproof diet."
However, Asprey has since shifted his stance. "I do not advocate a keto diet," he says. "There’s this gross oversimplification: ‘If you ever eat carbs again, you’re a bad person. Sugar is poison.’ Sugar is not poisonous. It’s the primary source of energy in your body. Excessive sugar is very bad for you, but it’s normal for people to have some."
The Problem with Toxic Carbs
Asprey's issue with carbs isn't carbs themselves, but "toxic carbs." He explains, "Wheat comes with gluten and lectins that punch holes in your gut lining. Excess fructose hammers your liver. Ultra-processed grains spike your blood sugar and leave you crashing an hour later." But low-toxin carbs are a different story. "White rice, low fructose fruits like blueberries, and occasionally a real homemade sourdough made from European soft wheat with proper fermentation," he recommends. "Those are carbs your body can actually use."
Cooking and Pairing for Optimal Benefits
According to Asprey, certain cooking methods and pairings can maximize the benefits of carbohydrates while minimizing their drawbacks. For instance, cooking white rice and cooling it before eating converts some of it to resistant starch, which feeds gut bacteria instead of spiking blood sugar. Additionally, C8 MCT oil, a supplement made from medium-chain triglycerides, can be taken alongside carbs to provide ketone fuel for the brain.
The Importance of Overall Health
At the end of the day, Asprey emphasizes that overall health is the sum of everything you do, not just a single diet choice. He recommends exercise, bloodwork, and stress management. "Do resistance training and maybe some high-intensity interval training, but not too much," he advises. "Also, get your hormones checked, including your thyroid hormones. Those can impact the way you process carbs."
Conclusion
In my opinion, Asprey's approach to carbs is a refreshing take on a much-maligned food group. By focusing on low-toxin carbs, smart cooking methods, and overall health, he offers a more nuanced perspective. What makes this particularly fascinating is the idea that carbs can be part of a healthy diet when eaten mindfully and in moderation. From my perspective, it's a reminder that the key to health is balance and listening to your body's unique needs.
