Why can a 150-pound man develop Type 2 diabetes… while a 300-pound man does not?

For decades, we were told a simple story: gain weight, get sick. Stay thin, stay safe. But that story falls apart the moment you look at real patients.

In this episode, I walk you through the concept that changed how we understand diabetes: the Personal Fat Threshold.

I explain why the issue isn’t how much fat you carry — it’s where your body can safely store it. Some people are born with a metabolic “bathtub” the size of a swimming pool. Others have a kitchen sink. When your personal storage limit is exceeded, fat spills into places it doesn’t belong — your liver, your pancreas, your muscles — and that’s when the real trouble begins.

We unpack:

* Why BMI is a blunt and often misleading tool

* What “ectopic fat” is and why it drives insulin resistance

* The Twin Cycle hypothesis and how liver fat and pancreatic fat feed each other

* Why beta cells in Type 2 diabetes may be stunned — not dead

* And why early diabetes can often be reversed

Then I explain something hopeful.

When you “drain the tub” — often by losing 10–15 kilograms — liver fat drops within days. Blood sugar can normalize within a week. Over weeks, the pancreas begins to recover. In many cases, diabetes goes into remission.

This isn’t about perfection. It’s about crossing back below your personal threshold.

Finally, I share how we translated this science into the 30-Day Blood Sugar Reset — a simple, daily micro-habit approach designed to lower the pressure on your liver and pancreas without turning your life upside down.

Because diabetes isn’t a moral failure.It isn’t a willpower problem.And it isn’t always about how you look.

It’s about overflow.
