A Mayo Clinic study found that people who primarily ate a fat-based diet (fish, healthy oils, avocados, nuts) had a 42% lower risk of developing Alzheimer's disease.

The diet-Alzheimer's connection is where the BRIGHT MINDS framework becomes most actionable. A Mayo Clinic study that compared dietary patterns found a dramatic gradient: people eating primarily healthy fats (fish, avocado, nuts, seeds) had 42% less Alzheimer's risk; those on a protein-dominant diet had 21% less risk; and those on the standard American diet — bread, pasta, potatoes, rice, fruit juice, sugar — had a staggering 400% increased risk. [1] — Dr. Daniel Amen "A Mayo Clinic study showed people on a fat-based diet (fish, avocado, nuts) had 42% less Alzheimer's risk, while those on a standard Americ…" 1:09:15 The mechanism is the insulin-diabetes type 3 hypothesis: chronic high blood sugar makes blood vessels brittle and prone to rupture, slowing healing and vastly increasing stroke risk. And having a stroke increases Alzheimer's risk tenfold. Fat cells themselves produce adipokines — inflammatory molecules that further damage the brain. Amen cites his 33,000-person study confirming that as body weight rises, brain size and function fall. He is not fatphaming, he insists — he is reporting science. For those designing a brain-protective diet, he favours a paleo approach with healthy fats, quality protein, and an abundance of plants over pure keto, which he worries may be insufficiently plant-diverse for a healthy gut microbiome.
A Mayo Clinic study showed people on a fat-based diet (fish, avocado, nuts) had 42% less Alzheimer's risk, while those on a standard American carbohydrate diet had 400% more risk. Sugar and foods that rapidly convert to sugar are the core culprit.
A Mayo Clinic study found people eating a primarily simple carbohydrate diet (bread, pasta, sugar) had a 400% increased risk of getting Alzheimer's disease versus those on a fat-based diet.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
