Dr. Chatterjee with Dr. David Unwin (Two hours and 16 minutes)

Published by: Dr Rangan Chatterjee - 15 Jan, 2026

If you have ever struggled with your weight, low energy, pre-diabetes or even type 2 diabetes, this is a conversation that could change your life. Dr David Unwin is an NHS GP who not only put his own type 2 diabetes into drug free remission, he has also helped over 150 patients do the same in a standard UK general practice – with ordinary people, on ordinary budgets, using food and lifestyle.

It’s estimated that around 87% of the adult population are metabolically unhealthy, which means that only a tiny minority of us are truly metabolically well. This is a serious issue because poor metabolic health is one of the root cause drivers of insulin resistance, type 2 diabetes, cardiovascular disease, strokes, Alzheimer’s and many forms of cancer.

In this week’s episode, we cover:
● The early signs of poor metabolic health, and why symptoms like fatigue, belly fat and brain fog are often overlooked.
● Why many issues we see as ‘normal ageing’ are actually signs of insulin resistance.
● How David himself reversed his own type 2 diabetes and, at the same time, improved his mood, energy and cognition.
● How reducing starchy carbohydrates if you have metabolic dys-regulation can dramatically improve blood sugar control.
● Why so many of us struggle with bread, pasta, and ultra processed foods – and how food addiction may be silently driving our behaviour.
● The two women who helped David rethink everything he thought he knew about food, hope and healing.
● And why it’s never too late to work on your metabolic health and why doing so can change every aspect of your life.

One of the things I love most about David is his passion. He really is someone who genuinely wants to improve the health and lives of his patients and our hope is this conversation empowers you to make small changes that will improve your blood sugar, weight, energy, and ultimately, your future.
