Straight from Samit’s best podcast episode, these biohacks aren’t just science-backed—they’re simple, practical, and life-changing. Want more energy, sharper focus, and better longevity? Start with these easy tweaks!
1️⃣ Start Your Day with an MCT Boost ☕️
One of the simplest brain hacks? Adding MCT oil to your morning coffee or shake. It fuels your brain with ketones, giving you instant mental clarity and lasting energy. MCTs bypass standard digestion and are directly converted into fuel, making them one of the fastest ways to feed your brain. Trust me, once you try it, you’ll never go back!
2️⃣ Hack Your Sleep Like a Pro 😴
Your recovery game starts at night. Here’s how to get deep, quality sleep:
- Keep your room cool & pitch dark (this supports melatonin production)
- Avoid screens 1 hour before bed (blue light blocks melatonin release!)
- Try magnesium & glycine—these calm the nervous system and improve deep sleep cycles
3️⃣ Fast Your Way to Longevity 🔄
Ever heard of autophagy? It’s your body’s built-in detox mode, where it clears out damaged cells and regenerates new ones. The easiest way to trigger it? Intermittent fasting (16:8).
- Fasting reduces inflammation and insulin spikes.
- Helps in preserving mitochondria, the powerhouses of your cells.
- Studies show fasting may even support brain plasticity and cognitive health!
4️⃣ Boost Your Brain with Nootropics 🧠
Nootropics = brain fuel. If you want sharper focus and mental clarity, try:
- Creatine (not just for muscles—great for memory and brain health!)
- Choline supplements (essential for neurotransmitter function)
- Acetyl-L-Carnitine (supports dopamine and mitochondrial function)
5️⃣ Cold Showers = Instant Mood & Energy Boost ❄️
Cold exposure increases dopamine, improves circulation, and fires up metabolism. It also enhances nitric oxide production, which improves vasodilation and oxygen transport to the brain. Start with 30 seconds at the end of your shower and build up from there!
6️⃣ Train Smarter, Not Longer with HIIT 🔥
Want maximum fat burn, endurance, and longevity in the shortest time? High-Intensity Interval Training (HIIT) is your best friend. It boosts VO2 max, which directly correlates with longevity. Studies show that HIIT can:
- Improve mitochondrial efficiency
- Boost growth hormone levels naturally
- Increase catecholamine neurotransmitters like dopamine, norepinephrine, and epinephrine
7️⃣ Fix Your Gut, Fix Your Life 🌿
Your gut is your second brain, and if it’s off, everything’s off. Keep it happy by:
- Eating fermented foods (kimchi, yogurt, sauerkraut)
- Taking probiotics & prebiotics
- Avoiding processed foods that cause inflammation
Your microbiome produces key neurotransmitters like serotonin (the happiness molecule), so gut health = mood stability!
8️⃣ Get That Morning Sun ☀️
Sunlight = nature’s best biohack. A few minutes of sunlight in the morning regulates your circadian rhythm, boosts vitamin D, and improves mood. Sunlight exposure also increases dopamine release, making it a natural energy booster!
9️⃣ Dopamine Hacks for Motivation ⚡
Dopamine is your motivation neurotransmitter—but junk dopamine (social media, sugar, endless scrolling) drains you. Try these real dopamine boosters instead:
- Complete small tasks ✅ (small wins = big momentum)
- Exercise 🏃♂️ (dopamine surge + endorphins = happiness!)
- Meditation & deep breathing 🧘 (reduces cortisol, sharpens focus)
- Tyrosine-rich foods like almonds and eggs (precursors to dopamine production)
🔟 Breathwork = Your Free Performance Enhancer 🧘♂️
Just 5-10 minutes of deep breathing a day can reduce stress, improve focus, and regulate your nervous system.
- Try box breathing (4-4-4-4 pattern) to calm anxiety.
- Wim Hof breathing increases oxygenation, which can boost mitochondrial function.
- Breathwork can even trigger nitric oxide release, which improves circulation and cognitive function!
Bonus: Modafinil & Nootropic Stacks 💊
One of the most powerful cognitive enhancers used by biohackers is modafinil, a dopamine-boosting wakefulness agent.
- Increases focus and attention span.
- Used by executives and students for high productivity.
- Not a supplement, but a prescription drug—so consult a doctor first!
Final Thoughts: Start Small, Think Big!
Biohacking doesn’t mean complicated science experiments—it’s about small, daily upgrades that make a huge difference over time. Pick one or two hacks, try them for a week, and feel the difference.
