The opposing travel strategies for this game garnered a lot of attention on social media, and for good reason. Really cool to see this natural experiment play out. @SleepAndSports— saw your podcast on this one and thought you might be interested
Sitting down for #MondayNightFootball and still thinking about *that* Melbourne game? Well, you’re in luck. Our new pre print (led by @datadude33) examines the different travel strategies used by @49ers and @RamsNFL in 🇦🇺 (as well as their prior 🇬🇧 games) and performance. 1/

Fitbit was ahead of the game on this one. They’ve had hourly move reminders on their watches for like 10 years. Very cool!
If you work at a desk, incorporating "micro-exercise breaks" into the day can greatly improve your metabolic health. A 12-week study found that doing 3-minute exercise breaks every hour during the workday (e.g., marching in place, push-ups, squats, heel raises) improved fasting blood glucose, insulin sensitivity, and even waist circumference, blood pressure, and HDL cholesterol. These metabolic benefits happen because muscle contraction stimulates insulin-independent glucose uptake. This is especially beneficial after meals. Big upside for a low time and effort investment!

It’s bittersweet just how interconnected physiological systems are. Your health can drastically improve (or worsen) by the smallest behavioral change.
Consuming around 75 grams of added sugar is enough to temporarily drop your testosterone by ~25% That’s about as much sugar as you'd get from a donut and a soda Research shows this testosterone drop occurs within just 2 hours, driven in part by insulin spikes interfering with hormonal signaling While the dip is temporary, regularly snacking on sugar-loaded, ultra-processed foods likely means frequent hormonal disruptions, impacting mood, energy, and muscle mass

Sleep optimization for high performers is still massively underdeveloped compared to training and nutrition. Excited to see companies like Absolute Rest tackling it. @Absolute_Rest
A few years ago, I was sitting in a closed-door meeting with some of the most elite minds in human performance on the planet. The topic: how do we actually optimize sleep for the world's highest performers? We went around the room. These were people responsible for astronauts, Tier 1 military operators, Olympic athletes, and billion-dollar executives. And the answer was the same from everyone: Consumer wearables OR a clinical sleep study in a creepy hospital. That was it. That was the ceiling. I've spent my career working with some of the most decorated athletes in history: UFC fighters, MLB All-Stars, Olympic medalists, Hall of Famers, etc. We have incredibly precise tools for just about everything for training, nutrition, recovery — but when it came to sleep, the most fundamental pillar of human performance, we were stuck choosing between a $300 tracker OR a single night wired up in a hospital so we could be told we may or may not have apnea and sent home with a CPAP machine. Both of those options share the same fatal flaw: they tell you that your sleep is bad. But THEY DON'T TELL YOU WHY - so they don't give you a real plan to fix or improve. That gap is what led me to co-found @Absolute_Rest with my partner, Josh Ruben, a neurotechnology entrepreneur who was running into the same wall while building eye-tracking diagnostic systems for NASA and the DOD. We asked ourselves a simple yet radical question: if you had an unlimited budget and wanted to build the world's most precise sleep-optimization system from scratch, what would it actually look like? Over the last five years, we've assembled an interdisciplinary team — sleep clinicians, neuroscientists, clinical psychologists, performance coaches — to build exactly that. Today, Absolute Rest combines AT-HOME & WIRELESS FDA-cleared clinical-grade hardware (as good or better than you'll find in any sleep hospital or research lab), advanced biomarker testing, environmental analysis, and world-class expert coaching into a single, end-to-end platform. What started as a bespoke program for elite athletes and executives has grown into something much bigger. We've now supported hundreds of clients from all walks of life who have one thing in common — they are done being told they're bad sleepers and ready to finally feel how sleep can go from an anchor to an advantage. I am grateful to those of you who've supported us thus far. HUGE things are coming soon with this remarkable company. absoluterest.com to learn more.

Few things are a bigger performance multiplier than sleep. Great opportunity to enhance athletic performance, even for elite athletes. Really interesting data from Ohio State athletes found, among other things: 1. Average sleep time ~7hr/night (most data indicate that should be closer to 9hr/night for maximal athletic performance) 2. 8 of their sports teams AVERAGE <7 hr/night as a group. More education. More monitoring. More feedback. More realistic schedules. Imagine what we would see!

Last year, $9B of the $35B that the National Institutes of Health (NIH) granted for research was used for administrative overhead, what is known as “indirect costs.” Today, NIH lowered the maximum indirect cost rate research institutions can charge the government to 15%, above what many major foundations allow and much lower than the 60%+ that some institutions charge the government today. This change will save more than $4B a year effective immediately.

Want to speed up your metabolism? Here's what science says about boosting your metabolism. There are numerous evidence-based ways that actually work! But… most of what you've heard is wrong. So, let’s clear up the confusion on what’s bogus, what’s real, and what ‘speeding up your metabolism’ really means - and what it does not! A deep dive into the research with surprising findings: First: You can't actually "speed up" your metabolism. That's like saying you can make your car drive faster when it's parked. What you can do is influence how many "miles" your metabolism drives each day. Here's how it works: Your Total Daily Energy Expenditure (TDEE) has 4 components: 1. Exercise Activity (EAT): 0-30% of calories 2. Non-Exercise Activity (NEAT): 5-30% 3. Thermal Effect of Food (TEF): 8-15% 4. Resting Metabolic Rate (RMR): 40-80% The research shows there are both acute (temporary; minutes to hours) and chronic (long-term; days to weeks or months) ways to influence these components. Most of the nonsense in this topic comes from people making claims about things that enhance ‘metabolic rate’ acutely - which as you’ll see, is actually quite easy to do. But this is very deceiving because acute increase often means very little in the long-term, especially for outcomes like fat loss, and they aren’t necessarily increasing your metabolism in the way you think (they ramp up RMR, for a few minutes, but then it goes right back down to normal, or even below baseline). So, it’s quite easy to deceive with legitimate science here. That said, let's look at what actually works for acute changes, and by how much: Acute Boosters: 1. Spicy foods (peppers, ginger, chilis, etc.) - Increases RMR by 3-5% - Effect lasts 1-2 hours - Often through capsaicin in chili peppers 2. Cold exposure - Lowering room temp by few degrees - Can lead to significant fat loss over time 3. Caffeine - Increases RMR by 3-11% - Lasts 1-3 hours - Also reduces appetite 4. Green tea - 4-5% RMR increase - Similar duration to caffeine - Compounds with caffeine for better results But here's what's really interesting: The chronic (long-term) changes are what really matter for sustainable results. Research shows 4 key factors for long-term metabolic enhancement: 1. Quality Sleep - Poor sleep reduces RMR - Increases hunger hormones - Can reduce fat loss by 55% - Affects muscle preservation 2. Fish Oil (3g/day) - 14% increase in RMR - 19% increase in fat oxidation - 4% increase in lean mass over 12 weeks 3. Muscle Mass - Each pound burns 6-10 extra calories daily - Primary factor in age-related metabolic decline - Explains up to 80% of RMR variance 4. Exercise - Strength training: +100 cal/day RMR - Cardio: +50-60 cal/day RMR - Combined: +75 cal/day RMR The most effective approach? Combining multiple strategies: - 200 cal from additional exercise - Fish oil + green tea (+25-50 cal) - Protein increase (+45 cal from TEF) - 15-min daily walk (+100 cal) - Small calorie reduction (-80 cal) This approach works because it: - Doesn't crash your metabolism - Preserves muscle mass - Avoids adaptive thermogenesis - Creates sustainable habits The key isn't finding one magic solution - it's stacking small, evidence-based changes. Remember: Your metabolism isn't "fast" or "slow." It's responding to your daily choices in sleep, nutrition, activity, and muscle mass. Focus on these factors consistently, and you'll create lasting metabolic health.

This is why @BioLayne is one of the few people in the health & fitness world I can actually trust. Great article breakdown on YT👍
Remember that cold water immersion study that 'led to more fat loss' that so many of you went nuts about? That study that I absolutely dismantled here? youtube.com/watch?v=GkmCvIJB… Yea that study? Yea it got retracted: pubmed.ncbi.nlm.nih.gov/3659… Hey @Garybrecka1 where you at?
