The Biohacks I Actually Recommend to Patients (And the Ones I Don't)

Patients bring me biohacking questions almost every week now — cold plunges, red light panels, continuous glucose monitors, $400 supplement stacks. Some of it is genuinely useful. Most of it is expensive noise dressed up as science. After thirty-six years in medicine, here’s my honest breakdown of what’s actually worth your time and money, and what isn’t.

The Trend I Take Seriously — and the Marketing I Don't

Some of what gets called biohacking is just good medicine with a trendier name — sleep optimization, resistance training, stress regulation. Other parts are marketing dressed up as science, sold to people who'd get the same result from eight hours of sleep and a walk. My filter is simple: does it change something I can measure, or does it just feel like progress?

Think about it: when you improve your sleep quality, manage stress effectively, and fuel your body with the right nutrients, you’re not just surviving—you’re thriving. This approach aligns perfectly with the “mouth, muscle, and mind” philosophy, which emphasizes balanced nutrition, physical fitness, and mental clarity. By biohacking these areas, you can create a foundation for a longer, healthier life.

My Filter: Does It Change a Lab Value or Just a Feeling?

Before I recommend anything to a patient, I ask one question: is there a measurable outcome — inflammatory markers, heart rate variability, fasting glucose, muscle mass — or is the improvement purely subjective? Subjective isn't worthless, but it's not the same as verified. Here's where that filter lands on the five biohacks I get asked about most.

At its core, biohacking for longevity is personalized. What works for one person might not work for another, so it’s important to listen to your body and track your progress. Some common biohacks include intermittent fasting, cold exposure, mindfulness meditation, and supplementing with antioxidants. These methods aim to reduce inflammation, improve cellular health, and support hormonal balance—all key factors in aging well.

The Five I Actually Recommend

None of these require a purchase over $30. But they're the ones I've watched move real numbers in real patients.

1. Sleep — Worth It, No Question

Sleep is your body’s natural repair system. Without enough restorative sleep, your cells can’t regenerate properly, and your immune system weakens. Aim for 7-9 hours of uninterrupted sleep each night. Create a bedtime routine that signals your body it’s time to wind down—think dim lights, no screens, and calming activities like reading or gentle stretching.

Try to keep your bedroom cool and dark. If you struggle with falling asleep, consider natural supplements like magnesium or herbal teas such as chamomile. Remember, good sleep hygiene is a cornerstone of longevity.

2. Nutrition Timing — Worth It, Skip the Supplements

What you eat directly impacts how you age. Focus on whole, nutrient-dense foods that support cellular health. Incorporate plenty of colourful vegetables, healthy fats like omega-3s, and lean proteins. Avoid processed foods and excessive sugar, which can accelerate inflammation and aging.

Experiment with intermittent fasting or time-restricted eating to give your digestive system a break and promote cellular cleanup processes like autophagy. Hydration is equally important—drink plenty of water throughout the day to keep your cells functioning optimally.

3. Resistance Training — Worth It, and Underrated

Exercise is a powerful biohack for longevity. It improves cardiovascular health, boosts mood, and supports muscle mass, which naturally declines with age. Aim for a mix of aerobic activities, strength training, and flexibility exercises.

Even short bursts of movement throughout the day can make a difference. Try walking during breaks, stretching at your desk, or doing bodyweight exercises at home. Consistency is key—find activities you enjoy so you’ll stick with them.

4. Stress Regulation — Worth It, Free

Chronic stress is a major aging accelerator. When your body is constantly in fight-or-flight mode, it produces excess cortisol, which can damage tissues and disrupt hormonal balance. Incorporate stress management techniques like mindfulness meditation, deep breathing exercises, or yoga.

Even a few minutes a day can help calm your nervous system and improve resilience. Don’t underestimate the power of social connections and laughter—they’re natural stress busters that support longevity.

5. Gut Health — Worth It, Skip the $80 Probiotic

Your gut health plays a crucial role in overall wellness and aging. A balanced microbiome supports digestion, immune function, and even mental health. Include fermented foods like yogurt, kimchi, and sauerkraut in your diet to nourish beneficial bacteria.

Consider prebiotic fibres found in foods like garlic, onions, and asparagus to feed your gut microbes. If needed, a high-quality probiotic supplement can help restore balance. Remember, a happy gut means a happier, longer life.

What I Actually Tell Patients to Track

Biohacking is a journey, not a destination. It’s important to track your progress and adjust your strategies as needed. Use journals, apps, or wearable devices to monitor sleep, activity, and mood. Celebrate small wins and be patient with setbacks—they’re part of the process.

Ask yourself regularly: How do I feel? Am I sleeping better? Do I have more energy? These questions help you stay connected to your goals and motivated to keep going. Remember, every positive change you make is a step toward a vibrant, longer life.

The One-Sentence Verdict

If a biohack doesn't improve your sleep, your bloodwork, or your ability to walk up a flight of stairs without getting winded, it's probably not worth your money. The five above will. Start there before you start anywhere else.

That's the whole verdict. Everything else is optional.
