The Light Diet

20/12/2025

New research publidhed only a few days ago shows natural daylight during the workday significantly improves glucose control, boosts fat oxidation, and strengthens our internal clocks — especially in people with type 2 diabetes!

In a randomized trial, participants exposed to real daylight through windows spent more time in a healthy glucose range and shifted their metabolism toward burning more fat compared with constant artificial lighting.

The study also found that daylight exposure changed muscle clock rhythms and metabolic markers, highlighting how powerful natural light is for metabolic health and circadian regulation.

You don’t have a “slow or sluggish metabolism.”

You have a mistimed one thats has lost its sense of “when you are”.

Your fat isn’t just storage that sits there to annoy you — it’s a light-reading organ that responds to the light you’re directly under.

Inside your fat cells lives a little protein called Opsin3, a blue-light sensor that literally sees light through your skin in your subcutaneous fat.
When unpolarised morning blue sun light hits your skin:

→ Opsin3 sends a signal straight to your hypothalamus, the part of your brain that runs your energy and appetite rhythms.

That signal says: “It’s daytime. Make energy available, start running fats through the TCA cycle and beta oxidation pathways.

But when blue light hits your skin at night — from screens, LEDs, or indoor lighting — that same pathway gets confused. At night your opsins shouldnt be seeing any blue light.

Your body hears: “It’s danger time. Save everything, we don’t know when we are or where we are or what we have on board so hoard everything”

You go into fat storage mode. Appetite up. Energy down and then you wonder why you’re lacking energy in the morning.

The new Nature Communications study just proved this:
When scientists removed that light sensor (Opsin3) from fat cells, the entire metabolic rhythm collapsed.

Energy metabolism plummeted
Appetite shot up, hunger increased.
Body temperature dropped
The brain’s timing system went off course and if the brain doesnt know “when” it is, the rest of the body loses sync too.

Eyes closed didn’t matter — the skin’s light exposure alone controlled the brain’s metabolic clock. This aspect is critical to understand.

Your skin alone can sense the time of the day.

You weren’t overeating or had poor food control.
You weren’t “broken.”
You were just inputting the wrong light code

✨ Fix the timing → fix the signal → fix the metabolism.

Latest research on sunlight and its benefits for eyesight from leading authority Professor Glen Jeffery shows that even through clothing, light penetrates deep into the body and improves visual functioning.
Start by building up your tolerance to light by spending time outdoors early morning and taking regular sun breaks during the day - great for eyesight and health. It's free, easy, accessible and necessary.

Long wavelength red light that can extend beyond the human visual range penetrates deeply through biological tissue. Exposure to these longer wavelengths improves mitochondrial function and ATP production. This can translate to improved ...

After years of research and experience, the uncomfortable truth is hard to ignore:

Allopathic medicine was never designed to make you truly healthy. It was designed to manage symptoms, just enough to keep you functioning, but not enough to free you from the system.

We’ve been taught to fear our symptoms, to silence them with prescriptions, procedures, and protocols that often suppress the very signals our bodies use to heal. But symptoms aren’t mistakes—they’re messages. They’re your body’s language, calling attention to deeper imbalances that can’t be fixed with a quick pharmaceutical solution.

This system is reactive by nature, wait until something breaks, then treat it. But by then, the root cause is buried, your natural healing instincts are overridden, and your dependency is locked in.

Real health doesn’t come from managing illness.
It comes from understanding your body, rebuilding trust with your biology, and creating the conditions for healing from the inside out. It means tuning into your innate ability to heal and truly believing that healing is possible for you.

The truth is, no one is more qualified to lead your healing than you.
Your body was never the problem. The system is.

And once you see it, you can’t unsee it.

DM CLEANSE if you're ready to take the first step towards true health.

From the American Heart Association !

Cardiovascular and metabolic health are influenced by the circadian system, which regulates 24-hour rhythms across numerous physiologic processes. Disruptions to circadian rhythmicity can adversely affect cardiometabolic function and health. Given the importance of circadian health to overall human....
