Dr. Jack Kruse, a board-certified neurosurgeon, gives a shocking explanation of why the sun—not food—is what controls blood sugar, mitochondria, and the risk of diabetes.

And here are 10 shocking things he revealed:👇

Kruse argues that sunlight is not just warming your skin.
It sends timing signals that tell your body:
• when to release hormones
• when to burn energy
• when to store glucose
• when to repair itself
His shocking point:
The same food affects your body differently

Your eyes see light.
Your brain interprets daytime.
But the clock says it should be night.
That mismatch disturbs melatonin, sleep and the body’s normal rhythm of insulin sensitivity.

When you see natural light early in the day, your brain receives a clear message:
The day has begun.
Kruse believes missing that signal can leave your hormones and metabolism operating at the wrong time.

Special cells in the eyes detect light and send timing information to the brain’s master clock.
That clock coordinates:
• cortisol
• melatonin
• appetite
• sleep
• glucose regulation
Your metabolism is running on a schedule.

They also respond to the environment surrounding those calories:
• sunlight
• darkness
• sleep
• temperature
• movement
According to Kruse, a “perfect” diet cannot fully compensate for living under artificial light all day

After a badly timed or shortened night of sleep, your cells respond less effectively to insulin.
You crave faster energy.
You feel hungrier.
And the same meal affects you differently than it would after restorative sleep.

Your body is generally better prepared to process food during its active daylight period.
Eating heavily late at night sends energy into a system preparing for repair and sleep.
Kruse’s point:
Your biology reads the clock before it reads the menu.

Different wavelengths of natural light reach the body throughout the day.
Kruse argues that these changing frequencies help coordinate hormones, circulation, cellular energy and sleep.
A vitamin D capsule cannot reproduce the entire solar signal.

We spend the day indoors under weak artificial light.
Then expose ourselves to bright screens at night.
Our bodies receive:
• darkness during the day
• simulated daylight at night
• food at every hour
Kruse believes this
