Robert Lufkin, MD: The NYT Bestselling Author on Metabolic Health, Prevention, and What Your Doctor Isn’t Testing
Dr. Robert Lufkin was a medical school professor at UCLA and USC for decades. He followed every guideline, got his checkups, and exercised regularly. Then four chronic diseases showed up at once, years earlier than his own father had developed them. His doctors offered lifetime prescriptions. Instead, he reversed all four through lifestyle changes alone.
His NYT bestselling book argues that metabolic dysfunction is the shared root behind most chronic diseases we die from. The uncomfortable part: standard bloodwork misses it. You can be lean, active, and have perfectly normal glucose while the real problem builds silently for years.
In this interview, he shares the single blood marker that reveals what routine panels don’t, why 80 to 90 percent of adults may already be affected, and how to layer nutrition, fasting, and recovery in the right order.
Short Hack Long Life
The 10-Minute Post-Meal Walk
A 10-minute walk immediately after eating lowers peak blood glucose by roughly 10% compared to sitting. The effect is strongest after dinner, when insulin sensitivity is naturally at its lowest. You don’t need intensity. A relaxed pace works. Timing matters more than duration: walking right after the meal outperforms a longer walk taken 30 minutes later. For anyone tracking metabolic health, this is one of the simplest interventions with consistent evidence behind it. A meta-analysis of 28 studies confirmed that walking after eating consistently outperforms exercising before meals for glucose control.
The Protocol:
🕐 When: Immediately after your largest meal. Dinner is ideal because insulin sensitivity drops in the evening. Set a recurring alarm if you tend to sit down after eating.
🎯 Specificity: 10 minutes at a comfortable, conversational pace. No need for workout clothes or elevated heart rate. Around the block, through the office, even pacing at home counts. The key is starting within 5 minutes of your last bite.
🚫 Friction removal: If weather or logistics make it impossible, walk in place or do light movement indoors. A shorter walk still beats sitting. If you skip a day, just resume the next meal.
📊 Tracking: If you wear a CGM, compare post-meal glucose spikes on walking vs. non-walking days. Without a CGM, track energy and alertness 60 minutes after dinner. Studies show measurable glucose improvements from the first session, with consistent benefits building over weeks.

WhatsApp Group Summary
Free Product Testing Program
Discussion: After a recent product test received strong interest, we announced a new research program where members can test wellness and longevity products for free in exchange for honest feedback.
The verdict: Members can sign up at newzapiens.com/register, head to “Research” in the menu, and apply. If selected, products arrive free. The first 100 spots are free before it becomes a paid feature.
Consider this: This is how the New Zapiens brand directory stays trustworthy. Real reviews from real users shape which brands get recommended. If you already track supplements, wearables, or test kits, your feedback has value. Secure your spot early.
Breastfeeding and Getting Sick
Discussion: A breastfeeding mom came down with a fever and asked the community what’s safe to take while nursing a 9-month-old.
The verdict: Members pointed to Embryotox, a database that rates medication safety during breastfeeding and pregnancy. Paracetamol and ibuprofen were flagged as commonly considered safe options, alongside staying hydrated and supplementing with electrolytes.
Consider this: Getting sick while breastfeeding is stressful because most packaging doesn’t tell you what’s safe. Embryotox is a free, evidence-based resource maintained by a German research institute that covers nearly every medication. Worth bookmarking before you need it. As always, check with your doctor before taking anything.
Where to Buy Your Health Stack in Europe
Discussion: A member asked whether there’s a DACH or EU-based platform with a wide range of longevity and wellness products, similar to Healf in the UK, to avoid customs fees.
The verdict: Biogena came up as a trusted pick for supplements, especially for anyone who struggles with large capsules since they offer liquid alternatives. For a broader range of health optimisation tools, members recommended Hololife Center, Upgraded Humans, and Live Helfi as EU-based shops with wide selections.
Consider this: The European health optimisation market is still fragmented compared to the US or UK, which makes curated discovery harder. Checking the New Zapiens brand directory is another way to find vetted brands that ship within Europe without the customs headache.

Marie-Luise Huber
A nutrition scientist and dietitian specialising in metabolic health, hormones, and routines that fit real life. She built her health stack around what actually works when time is short, from supplements to wearables.
Marie-Luise`s Health Routine
Morning
Marie-Luise starts around 6:15 with a light stretch and ginger-lemon tea, then drops her toddler at daycare by 8:15, squeezing in a run or bike ride when the weather allows for early sunlight and movement. Breakfast is yoghurt loaded with collagen, hemp seeds, berries, cocoa nibs, and sun butter, paired with a vitamin D+K2 supplement. Deep work and client calls run through the morning, usually fuelled by a coffee with creatine stirred in.
Afternoon
Lunch is protein, fibre, and colour: greens, beans, salmon, avocado, or whatever leftovers are ready. A 10-to-20-minute walk right after eating keeps glucose steady and resets her focus for a second block of coaching, programme development, and writing. Around 3:00 she has a light snack and trains, alternating between strength sessions, short runs, or walks depending on energy.
