Dr. David Unwin is an NHS GP with over 40 years in general practice, known for his expertise in reversing Type 2 diabetes through dietary changes. He was named NHS Innovator of the Year in 2016 and is the co-author of the most-read paper in BMJ Open, on reversing Type 2 diabetes through a low-carbohydrate diet. He explains: ◼ The "teaspoon of sugar" test that exposes the hidden glucose in your food ◼ Why your liver silently fills with fat for years before anything shows up ◼ Why you can't stop eating certain foods and what food addiction really is ◼ How sugar feeds cancer cells faster and the diet that slows them ◼How Ozempic quiets food cravings and why it's only part of the answer 00:00 Intro 02:20 Why Your Future Health Depends On This One Question 02:44 What It Really Takes To Create The Future You Want 06:50 What Actually Happens Inside Your Body With Diabetes 14:36 The Hidden Truth About What’s Really In Your Food 15:56 The Moment That Completely Changed How He Saw Medicine 17:09 The Real Reason Doctors Are Incentivized The Wrong Way 22:00 How Food Becomes Medicine Or Makes You Sicker 28:59 What Happens When You Truly Transform Your Health 30:04 The Everyday Habits Quietly Destroying Your Health 33:05 Why Most People’s Idea Of Healthy Is Completely Wrong 35:20 Is Dried Fruit Healthy Or A Sugar Trap In Disguise 38:26 These Healthy Foods Have More Sugar Than You Think 45:25 Is Orange Juice Actually Good For You 46:56 The Truth About White Milk And Dark Chocolate 49:28 Why Smoothies Aren’t As Healthy As You Think 52:11 How To Tell If Your Food Is Actually Healthy 55:24 How Your Body Secretly Turns Carbs Into Sugar 57:18 Is Bread Ruining Your Health 59:22 Ads 01:01:25 What Nutrition Labels Aren’t Telling You 01:05:47 Keto Diet Solution Or Hidden Risk 01:10:25 How To Set Health Goals That Actually Work 01:20:35 How To Help Loved Ones Change Before It’s Too Late 01:31:21 The 4 Step Plan To Break Addiction For Good 01:34:50 Why Addiction Leads To Deception 01:35:50 Book Giveaway 01:37:27 Ads 01:39:42 The Link Between Diet And Cancer What This Means 01:45:09 Why Our Healthspan Is Quietly Declining 01:48:21 The Simple String Test That Reveals Your Metabolic Health 01:50:25 Are Supplements Helping Or Hurting You 01:53:04 The Magnesium Story That Will Change How You Think 02:02:57 Guest’s Last Question 02:09:56 A Final Story You Won’t Forget Enter here for the chance to win one of 1000 copies of Dr. Jen Unwin’s Book, “Fork in the Road”: https://link.thediaryofaceo.com/6OxWpCa Enjoyed the episode?

WHAT IT’S REALLY ABOUT

Dr. David Unwin exposes hidden sugars and metabolic health collapse worldwide

  1. Dr. David Unwin explains the insulin-driven pathway from high-carb diets to fatty liver, insulin resistance, and ultimately type 2 diabetes—often developing silently for years before diagnosis.
  2. He argues many “healthy” staples (cereal, rice, potatoes, bread, juice, smoothies, dried fruit) function as concentrated sugar in the body, and demonstrates this using his “teaspoons of sugar equivalent” (glycemic load) framework.
  3. Unwin describes how low-carb, real-food approaches can produce high rates of blood-sugar normalization, especially when implemented early (prediabetes and early diabetes), reducing reliance on medication.
  4. The episode highlights systemic issues—misleading food marketing, inadequate nutrition education, and healthcare incentives that favor prescribing—alongside practical tools like continuous glucose monitors and a simple waist-to-height “string test.”
  5. A major theme is behavior change and addiction: ultra-processed food can create compulsive, deceptive behaviors, and recovery often requires honesty, abstinence plans, support, and sometimes combined therapy (e.g., CGM feedback plus GLP-1 drugs).

IDEAS WORTH REMEMBERING

5 ideas

Belly fat is a stronger warning sign than overall weight.

Unwin emphasizes central adiposity as a marker of insulin resistance; his quick self-check is waist circumference less than half your height using a piece of string.

Starchy foods can behave like sugar even if they don’t taste sweet.

He describes starch as “glucose molecules holding hands” that digestion breaks apart; cereals, rice, bread, and potatoes can drive large glucose/insulin responses despite no “added sugar.”

Use glycemic load (portion impact), not just glycemic index (food ranking).

Glycemic load better reflects real eating because it accounts for serving size and density, helping predict actual blood-sugar effect rather than abstract comparisons.

Many ‘everyday healthy’ foods can equal or exceed candy in sugar impact.

Using his sugar-equivalent method, Unwin shows common portions like cornflakes, bananas, potatoes, and especially boiled white rice can represent surprisingly high “teaspoons of sugar.”

Earlier dietary intervention dramatically improves odds of reversal.

From his practice data, Unwin reports far higher normalization rates when low-carb changes begin at prediabetes versus after years of established type 2 diabetes, framing it as “a stitch in time.”

WORDS WORTH SAVING

We’re all sleepwalking into a metabolic disaster, and the people paying the greatest price, in my opinion, are young people, and it’s a scandal, and I’m hopping mad really.

For every year that you have poorly controlled Type 2 diabetes, you’re losing 100 days of life.

I had to learn online, uh, 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.

— Dr. David Unwin

What you’ve actually done is have sugar with your sugar, with your sugar, sugar, sugar, sugar, sugar all day long. There’s hardly any protein.
