TL;DR

Dr. David Unwin, one of the UK's top 10 most influential doctors, explains how a pandemic of poor metabolic health driven by hidden sugars in everyday foods is silently destroying lives. He shares how he reversed his own type 2 diabetes and helped hundreds of patients achieve drug-free remission through low-carb dietary changes.

Key points

A third of all people with type 2 diabetes don't know they have it, and for every year it goes poorly controlled, 100 days of life are lost

Starchy carbs like white rice, potatoes, corn flakes, and bananas convert to far more sugar in the body than most people realise — 150g of boiled rice equals 10 teaspoons of sugar, more than a chocolate bar

Fatty liver disease affects a third of people in the developed world, silently progresses for up to 10 years, causes insulin resistance, and is a direct precursor to type 2 diabetes

93% of pre-diabetics who go low-carb achieve completely normal blood sugar; waiting until full type 2 diabetes drops that success rate to 73%, then 50% after five more years

The entire normal human bloodstream contains only about one teaspoon of sugar at any given time, illustrating how easily dietary glucose overwhelms the body's regulatory system

Actionable insights

→

Check your waist measurement — it should be less than half your height; excess belly fat is a stronger risk indicator than fat on limbs

→

Use Dr. Unwin's teaspoon-of-sugar equivalent system to evaluate foods: every 4g of carbohydrate on a nutrition label is broadly equivalent to a teaspoon of sugar, regardless of whether the food tastes sweet

→

Base meals on protein first (eggs, chicken, meat), add green vegetables, and use full-fat dressings like olive oil, butter, or mayo — avoid packet sauces like barbecue sauce which can contain 30 sugar cubes per bottle

→

Avoid fruit juices and smoothies — juicing removes fibre and delivers a rapid blood sugar spike equivalent to eating multiple portions of whole fruit at once

→

If you suspect pre-diabetes or insulin resistance, act early — the window for drug-free reversal through low-carb eating narrows significantly the longer you wait

Notable quotes

“She said, 'I had to learn online that bread is sugar, that rice is sugar, that breakfast cereals are sugar, and when I cut those foods, I don't need your metformin now. This is school boy biology. You should have learned that when you were 16.'”

“The failure was not theirs. It was mine. Imagine 25 years of blaming patients for their failure to lose weight and it was my failure because I didn't give them advice that worked.”

“We could take all the blood out of me — five litres. How much sugar would be in that five litres of blood? That is all there is. One sugar cube.”
