Your bloodstream is designed to carry just one teaspoon of sugar at any time. Most people consume thirty or forty a day.
That excess triggers a hormone called insulin. When insulin stays elevated for years, it quietly drives cancer, Alzheimer's, heart disease, type 2 diabetes, and dozens more conditions. And almost nobody is testing for it.
In 2024, the BMJ published a study of ten million people linking modern food to 32 separate diseases. Every major newspaper covered it. Not one answered the obvious question: what is the single mechanism connecting a packet of biscuits to cancer, dementia, and heart failure?
The answer is insulin. Not ultra-processed food. Not calories. Not fat or salt. The insulin.
In The Insulin Problem, you will discover:
- Why insulin resistance is the most important number your doctor can measure.
- How elevated insulin drives cancer, Alzheimer's, heart disease, and type 2 diabetes through clear, documented pathways.
- Why the government's dietary guidelines need a serious rethink.
- The blood markers that reveal your true metabolic health. How the weight loss jabs work and what they are actually doing inside your body.
- And what you can do about all of it, starting with your next meal.
This book gives you the one answer behind 32 diseases so you can stop treating symptoms and start reversing the cause.
Steve Bennett is a British entrepreneur who has featured on the Sunday Times Fast Track 100 twice, topping the list in 2012. He has run four marathons fasted, sailed the Atlantic, walked to the North Pole, and spent the last decade researching metabolic health alongside leading scientists. Not a doctor. Someone who refused to accept that chronic disease was inevitable, found the science that proved it was not, and wrote it down in plain English.
The book draws on the research of Dr Isabella Cooper and Professor Ben Bikman, two of the world's foremost scientists in insulin and metabolic health.
If you want to understand insulin resistance, blood sugar, and the root causes of chronic disease, this book was written for you.
