A study put elite athletes who burned almost no carbs on a treadmill. They recorded the highest fat-burning rate ever measured in a human.
The FASTER study. 2016. Published in Metabolism. Twenty of the best ultra-endurance athletes on earth. Ultramarathoners. Ironman triathletes. The kind of people whose careers depend on knowing exactly what fuel works.
They were split into two groups.
Ten ate the standard high-carb athlete diet. The diet every sports nutritionist still pushes. Eat the carbs. Load the carbs. You cannot perform without the carbs.
Ten had been low-carb and keto-adapted for an average of twenty months. Same elite level. Same competitions. No carbs.
Both groups ran three hours on a treadmill. Researchers measured exactly what fuel each body was burning, breath by breath.
Here is what they found.
The keto group burned fat at 2.3 times the rate of the carb group. Peak fat oxidation hit 1.5 grams per minute.
The textbooks said the human body maxes out near 0.7 grams per minute. The keto athletes doubled the supposed limit.
The highest fat-burning rate ever measured in a human, full stop.
Then the part that should have ended the carb-loading dogma forever.
The fear was that without carbs they would run out of muscle glycogen mid-race. They did not. Their glycogen use during the run and their refill afterward matched the carb athletes exactly.
They were running on their own fat at elite intensity. With glycogen behaving identically.
The body was never carb-dependent.
It was carb-trained.
You can train it differently.
Almost a decade later, every endurance handbook still tells athletes to load up on carbs. The data has been sitting there the whole time.
Chelsea Football Club is delighted to announce the appointment of Xabi Alonso as Manager of the Men’s Team.
The Spaniard will begin his role on July 1, 2026, having agreed a four-year contract at Stamford Bridge.
Welcome to Chelsea, Xabi!
Klopp via FB: “ Since I stepped away from the daily pressure and noise, I’ve entered a completely new phase of my life. To be completely honest with you, some days I didn’t even know what games were being played! I’ve been entirely disconnected from that world, and for the first time in 25 years, I am living a truly normal and quiet life.I spend my time now working out, enjoying the good weather, and spending as much time as possible with my grandchildren and family—the simple things that football kept me away from for so many years. For a long time, I lived like James Bond, waking up every day to do the same intense routine over and over again to succeed. Now, there is no more standing in the rain for hours, and no more press conferences three times a week.I’m 58 now, and although people keep asking me about returning to coaching, at this moment, I don’t feel like I miss anything at all. I am incredibly happy with what I am doing now, whether it's my new role with Red Bull or just being a normal guy enjoying every single minute of his https://t.co/koRdt5DwOx is too short, and now it’s finally time for me to enjoy it and all the little details I never got to see before.I hope you all have a wonderful day, and keep smiling! ❤️”
🇫🇷🏔️Ascension du Mont Blanc en 4 h 41 min 24 s : l’exploit de deux Français. Ces deux guides de montagne ont battu le précédent record en réalisant l’aller-retour depuis Chamonix. #JT20h
We’re going to need a few days to recover from this one… 😮💨
2 men under 2 hours. 3 men breaking the world record.
We have officially entered the new era of marathon running 🫳🎤
Many years of TrainingPeaks data from top cyclists I have worked with show a consistent pattern:
~40–60% of the best 5, 10 and 20 min power outputs were achieved during training in individually prescribed HIIT sessions
~40–60% occur during races.
In simple terms:
-Zone 2 builds the mitochondrial engine.
-HIIT adds the glycolytic turbo.
Both bioenergetic stimuli must coexist in a training plan of competitive and recreational athletes.
No engine ➡️ the turbo blows up.
This is why the Zone 2 vs HIIT debate is futile. It was never either/or.

For decades, peer review has been treated as the gold standard of scientific validation.
Yet many scientists know the reality: the system is far from perfect. Peer review is broken and sometimes even corrupted.
The process can be slow, inconsistent, and vulnerable to bias. Reviewers are sometimes asked to judge work outside their true expertise. In other cases, they may be evaluating ideas that challenge the very paradigm in which they were trained. And occasionally, reviewers are simply competitors.
Ironically, the most prestigious journals can also be the most conservative. Truly new ideas are often met with skepticism, while safer work that fits the current narrative moves more easily through the system.
Increasingly, papers are judged less by the originality of the idea and more by the volume of data, the sophistication of statistics, and the beauty of the figures. Science risks becoming data-rich but idea-poor.
But there is an important reality to remember: journals do not ultimately decide the impact of scientific work. Impact is decided later, by the community. By the scientists who read it, test it, debate it, and cite it.
In the end, citations and ideas determine the legacy of a paper, not the impact factor of the journal that first published it.
Science has always advanced by questioning assumptions. Perhaps it is time we also question the system that filters scientific ideas.
Unreal numbers 👀⚡️
"JPMorgan estimates that, had Germany not phased out nuclear power, the country would have generated 50% less electricity from fossil fuels and 84% less electricity from natural gas in 2024. Electricity prices in Germany would have been around 25% lower, and the country would have imported half as much electricity.."

“Dad, was Nadal actually as good as they say?”
“Son, he defeated peak Federer at Wimbledon. Beat prime Djokovic in two USO finals. Olympic Gold in his first try. Won AO from 0-2 down at 36... he was the best.”
“Wow! But that's all on grass & HC. Was he not that good on clay?”
“Hi! I’m Dave Grohl. I’m not Jewish.”
But the @foofighters founder is still excited to release a Chanukah album.
One song on each of the 8 days.
Dave Grohl, you are my new favourite little latke.🕎
