Insulin is a fat-maxxing hormone.
You might think you're eating healthy because someone told you to eat "mostly plants" or that "oatmeal reduces cholesterol" but what you don't realize is that the insulin spikes these high carbohydrate foods create are locking you into a fat-storing metabolism.

It has come to our attention that some medical doctors and Instagram influencers may have been living under a rock since 2023 when @joerogan explained to @derekmoreplatesmoredates that cold plunge should be done BEFORE exercise, and not after -- a fact that Joe picked up from @seagertp and the @hubermanlab podcast with Stanford Professor Craig Heller.
If this is new to you, then please accept our apologies for thinking that the man with the most popular podcast in the world could not possibly have escaped the attention of the Instagram experts who have suddenly discovered some new secret knowledge of ice baths.
After 3 years.
Watch back @emilykaplanX & Dr. Drew cover COVID, Fauci, and more!
Texts extracted from Dr. Fauci's iPhone include a 2021 thread admitting a 2nd COVID vaccine "theoretically could be associated with miscarriage." But is this really a smoking gun? @sasha_latypova @emilykaplanx & @dryostradamus join me LIVE at 7et xitter.gq/i/broadcasts/1jGXgBgnO…

Medical history is filled with discoveries that were rejected long before they were accepted.
From handwashing to ulcers caused by H. pylori, many of medicine's biggest breakthroughs challenged the prevailing consensus, and faced resistance because of it.
The lesson isn't that every new idea is right. It's that science moves forward by questioning assumptions, testing evidence, and remaining willing to change our minds when better data emerges.
This article was featured in this week's Broken Science Weekly newsletter. Every Wednesday, we highlight our newest articles, videos, podcasts, and research worth your attention- so you'll always be the first to see new content as it's released.

Women were told to fear estrogen. Meanwhile, osteoporosis drugs became blockbusters. It’s time to ask who benefited.

Dehydration can cause a headache primarily because a lack of adequate fluid volume leads to a temporary shrinking of brain tissue as water is drawn out of cells. This microscopic reduction in volume causes the brain to pull slightly away from the skull, putting tension on the surrounding pain-sensitive membranes and blood vessels.
Additionally, dehydration triggers a reduction in blood volume and blood pressure, which decreases the overall delivery of oxygen and essential nutrients to the brain. In response, blood vessels in the brain may dilate or constrict irregularly, further activating local pain pathways and resulting in a dull, throbbing ache or tension-like headache.
Electrolyte imbalances that frequently accompany dehydration—such as drops in sodium and potassium— also impair normal nerve signaling and muscular tension regulation. Rehydrating by drinking water and restoring electrolyte balance typically alleviates these pressures and resolves the headache as normal fluid volume and blood flow are restored. #explainingyourbody

Muscle memory is a neuromuscular process where a specific motor skill or movement sequence is consolidated into procedural memory through repetition, allowing you to perform it automatically without conscious thought. Despite the name, the physical muscles themselves do not actually store memories; instead, the adaptation occurs primarily within the motor cortex of the brain and the peripheral nervous system.
When you practice a new physical activity-such as playing an instrument, typing, or riding a bike-your brain establishes and strengthens dedicated neural pathways that coordinate the exact timing and firing of motor units.
With consistent repetition, these pathways become heavily myelinated, enabling electrical signals to travel faster and more efficiently so that the movement can be executed fluidly and effortlessly.
At the cellular level, long-term training can also induce physical changes within muscle fibers, such as adding new myonuclei that permanently increase the muscle's capacity for growth and rapid skill re-acquisition. This structural adaptation explains why physical skills or fitness levels that have deteriorated over time can often be relearned and recovered much faster than it took to acquire them initially. #explainingyourbody

Why do some people naturally maintain their weight while others seem to be constantly fighting their biology?
The answer may have less to do with willpower and more to do with where your body sends its fuel.
Fuel partitioning describes how the energy you consume is distributed between:
-Producing cellular energy
- Supporting activity and metabolism
- Being stored as body fat
This shifts the question from “How much are you eating?” to “Where is the fuel going?”
Understanding obesity starts with understanding fuel partitioning—not simply calories.

The U.S spends billions treating chronic disease, yet far less attention is given to what may be helping drive it in the first place.
Ultra-processed foods have become a staple of the modern American diet, while rates of depression, anxiety, type 2 diabetes, heart disease, and certain cancers continue to rise.
The root cause matters.

The value of a burpee.
Three months ago when Barb started training, she was using a walker. She is training for a cruise 🚢 in November, but has said she’ll now continue afterward.
She has also given up donuts 🍩 and has vowed to walk the grocery store (vs motor cart). – at Ottawa, Ontario

Every hour, 70 people die from cancer in the United States. That’s roughly 1,700 lives every day.
When I read those stats, I realised how overwhelming it can feel to try understand this disease and why it can feel almost impossible to navigate the science behind it.
That is why I invited Professor Thomas Seyfried back to try and understand the science further, question the system and explore what we may still be getting wrong.
Thomas has spent 50 years researching cancer. He is a Professor of Biology at Boston College, the author of more than 150 peer-reviewed papers and one of the most passionate people I have met when speaking about this disease.
His work explores a metabolic view of cancer. In simpler terms, he believes we need to pay much closer attention to how cancer cells create energy, how their metabolism differs from healthy cells and what that could mean for future research.
We discussed things like:
- The new research he brought into the studio in a confidential envelope…
- How damaged mitochondria could change the way we understand cancer.
- The three things he believes matter most for living longer.
- Why cutting sugar alone does not fully explain how cancer cells survive.
- Where keto can become dangerous or misunderstood?!
- Changes he would make if he were responsible for public health.
There were moments when I asked Thomas to simplify his explanations and pushed for clarity on what's been demonstrated in research and what still needs further study.
That distinction matters.
Thomas's work is focused on scientific research, not clinical practice.
I left this conversation thinking about how progress often begins - someone asks a question that doesn't fit comfortably inside the existing explanation, then spends decades trying to answer it.
Cancer will affect almost every family in some way. This is a challenging conversation, but one I believe is worth hearing in full.
