Fatty Liver Expert: The Toxic Ingredient Silently Filling Your Liver With Fat - Dr David Unwin
The Diary of a CEO
· · Hosts: Steven Bartlett · Guests: David Unwin
Summary
David Unwin argues that poor metabolic health is now a “pandemic” and that many people are sleepwalking into type 2 diabetes, fatty liver, and related disease without realizing it. He frames health as a choice among different future outcomes, and says the best way to change that trajectory is to understand how everyday food drives insulin, liver fat, hunger, and eventually disease. He also argues that younger people have the most to gain from changing course early, because every year of poorly controlled type 2 diabetes costs life expectancy.
A major theme is that most people misunderstand sugar. Unwin says many starchy foods that do not taste sweet still act like sugar in the body, and he uses his “teaspoon of sugar” system to show how cereal, potatoes, rice, bananas, bread, and even orange juice can carry a much bigger glucose load than most people expect. He says this hidden carbohydrate burden helps explain why people stay hungry, snack more, and gain fat in the belly and liver.
He also says his own shift to low-carb medicine came after a patient challenged him on metformin use and insisted bread and cereal were the real problem. From there, he and his wife began a small low-carb experiment that produced dramatic weight loss, improved liver tests, better blood pressure, and higher energy. His practical advice is to build meals around protein, keep an eye on carbohydrate content, and use real-world testing, including continuous glucose monitoring, to see how specific foods affect the body.
Key takeaways
- David Unwin says poorly controlled type 2 diabetes costs about 100 days of life per year and is increasingly affecting young people.
- He says fatty liver can develop silently for about 10 years and then drive insulin resistance and worsening blood sugar.
- Unwin’s “teaspoon of sugar” framework puts common foods like cornflakes, potatoes, rice, bananas, and bread in a much higher sugar-equivalent range than most people expect.
- He says his practice saw strong results with low-carb changes, including 93% normal blood sugar in pre-diabetes and 73% in type 2 diabetes when changes are made early.
- Unwin argues that meals should be built around protein and that labels matter because many “healthy” products are really high-carb, high-sugar foods.

How the episode opens
Your waist should be less than half your height. So half of that string should go around the fattest bit of your belly. And this is a really simple test for everybody at home. — I mean, it's not.
Yeah, you've just done it. You've passed. But fat on your belly is more worrying than fat on your legs or on your arms.
And unfortunately, we've started to normalize things like the dad bot without realizing that isn't how you're supposed to be. And maybe a third of all the people in the world with type 2 diabetes don't even know they have it. But every year that you have poorly controlled type 2 diabetes, you're losing 100 days of life.
And it's because people don't know the truth being fooled with the packeting and advertising.
So, let's talk about the food we have on this table because this is how much sugar I would have thought was in all of these things here. Cereal, a potato, white rice, a banana, and a chocolate bar. — So, now I'm going to give you the correct figure. The corn flakes is 1 2 3 4 5 6 7 8. That chocolate bar is 7 and 1/2. The banana that's six. And then the potato is actually
Oh my gosh. — And then 150 g of boiled rice is — Oh, I thought rice was healthy. — But each of us has a number of different health futures. And what I'm interested in is how do I get you to pick a lifestyle that will get you the future you want? Because my job is about behavior change.
The floor is yours. — All right. So, off we go. This is super interesting to me. My team given me this report to show me how many of you that watch this show subscribe.
