10 Key Concepts
Maturity Onset Diabetes
The former name for Type 2 diabetes, indicating it was previously only seen in older individuals, highlighting the shift to younger demographics now affected by the condition.
Insulin
A hormone produced by the pancreas that pushes sugar (glucose) from the bloodstream into cells for energy or converts excess sugar into fat for storage, protecting arteries from damage.
Fatty Liver
A condition where the liver fills with fat, often due to excessive glucose intake, which interferes with insulin's function, leading to insulin resistance.
Insulin Resistance
A state where the body's cells become less responsive to insulin, requiring the pancreas to produce more insulin to manage blood sugar. This can eventually lead to pancreatic fatigue and inability to regulate blood sugar, resulting in Type 2 diabetes.
Glycemic Index (GI)
A measure of how quickly a carbohydrate food raises blood glucose levels compared to pure glucose. It indicates the speed at which sugar enters the bloodstream.
Glycemic Load (GL)
A more accurate measure than GI, predicting how a specific portion of food will affect blood sugar. It factors in the density of sugar and nutrients like protein and fiber within that portion.
Teaspoon of Sugar Equivalent System
A method developed by Dr. Unwin to quickly communicate the glycemic load of foods by converting their carbohydrate content into an equivalent number of 4-gram teaspoons of sugar, making it easier to understand dietary impact.
Starchy Carbohydrates
Foods like bread, rice, and potatoes that are composed of glucose molecules 'holding hands' (starch). These are broken down into free sugar (glucose) during digestion, even if they don't taste sweet.
Ultra-Processed Food Addiction
A condition where individuals, even highly intelligent ones, repeatedly consume foods that harm their health due to addictive properties. This often leads to deceit, secrecy, and negative impacts on self-esteem.
Healthspan
The number of years a person lives in good health, free from chronic illness and disability. It is distinct from overall lifespan, which is simply the total number of years lived.
12 Questions Answered
While cardiovascular issues are common, cancer is a rising cause of mortality, with eight forms strongly associated with diabetes.
A very high blood sugar can damage the non-stick lining of arteries (glycocalyx) within six hours.
The hormone insulin pushes excess sugar out of the bloodstream and converts it into fat inside cells, particularly in the belly and liver, as it's safer than having high blood sugar damage arteries.
Fatty liver interferes with insulin's effectiveness, leading to insulin resistance, which then forces the pancreas to produce more insulin, eventually leading to pancreatic fatigue and Type 2 diabetes.
In Dr. Unwin's practice, 93% of people with pre-diabetes achieved normal blood sugar with a low-carb diet, and 73% of early Type 2 diabetes patients achieved normal blood sugar.
Glycemic load considers the portion size and the density of sugar and nutrients (like protein and fiber) in a food, providing a more accurate prediction of its effect on blood sugar.
Marketing often misleads consumers (e.g., "made with real fruit juice"), and there's a lack of basic nutrition education, leading people to believe foods like dried fruit, orange juice, cereals, rice, and potatoes are inherently healthy.
A healthy adult's entire blood system contains only about one 4-gram teaspoon (or sugar cube) of glucose.
Reducing carbohydrate intake stabilizes blood sugar and insulin levels, which significantly reduces hunger and cravings, making it easier to fast or resist tempting foods.
The first step is to engage them in discussing their goals and hopes for a better future, offering gentle support and tolerance rather than policing or judgment, which can lead to deceit.
High sugar intake causes chronic hyperinsulinemia (high insulin levels), which can inhibit natural cell self-destruction (apoptosis), feed tumor growth, shorten telomeres (linked to aging and cancer risk), and elevate inflammation markers (CRPs) correlated with tumor progression.
While a real food, low-carb diet is preferred, modern farming practices have depleted soil nutrients, making it difficult to get enough essential minerals like magnesium from diet alone. Supplementation can be beneficial for specific deficiencies (e.g., magnesium, Vitamin D), but over-supplementation should be avoided.
18 Actionable Insights
1. Use the String Test for Metabolic Health
Measure your height with a piece of string, then cut it in half. This half-string should go around the fattest part of your belly; if it doesn’t, it’s a simple indicator of potential metabolic health issues.
2. Prioritize Protein and Green Vegetables
Base your meals on protein and lots of green vegetables, and use healthy fats like full-fat mayo, butter, or olive oil to make them tasty, rather than sugary sauces.
3. Be Wary of Packaged Foods
Treat food out of packets as ‘Russian roulette’ due to hidden sugars and complex ingredients. Opt for real, unprocessed foods whenever possible.
4. Check Carbohydrate Content on Labels
When eating packaged foods, look at the carbohydrate content in addition to added sugars. In the UK, carbohydrate content (excluding fiber) indicates how much will turn into sugar; in the US, subtract fiber from total carbs to estimate absorbable carbs.
5. Understand Starchy Carbs as Sugar
Recognize that starchy carbohydrates (like those in bread, rice, potatoes, and cereals) are essentially glucose molecules that turn into free sugar upon digestion, even if they don’t taste sweet.
6. Avoid Sugary Drinks and Juices
Sugary drinks and fruit juices cause rapid blood sugar spikes, leading to insulin surges and subsequent hunger, perpetuating a cycle of sugar consumption.
7. Choose Dark Chocolate Over Milk/White
If you crave chocolate, opt for 90% dark chocolate, which has significantly less sugar (around two teaspoons per bar) compared to milk or white chocolate (which can be 70-80% sugar).
8. Question “Healthy” Smoothies
Be aware that many commercial smoothies are high in sugar, despite being marketed as healthy, and can cause significant blood sugar spikes.
9. Consider a Continuous Glucose Monitor (CGM)
Use a CGM to get immediate feedback on how different foods affect your blood sugar levels, helping you identify problematic foods and make informed dietary choices.
10. Acknowledge Food Addiction Honestly
The first step to overcoming food addiction is honest self-acknowledgment of the problem, even if you can’t share it with others.
11. Identify Specific Problem Foods
Pinpoint the exact foods that trigger addictive eating patterns.
12. Plan for Abstinence, Not Moderation
If you have an addictive potential with certain foods, plan for complete abstinence rather than attempting moderation, as one ‘slip’ can lead back to uncontrolled consumption.
13. Seek Gentle Support for Change
If sharing your struggles with loved ones, ask for gentle support and tolerance, rather than policing or judgment, which can lead to deceit and isolation.
14. Experiment with Your Diet
View your body as an experiment. Don’t be afraid to try different dietary approaches (like low-carb) and measure the results (e.g., blood work, weight, energy levels) to see what works best for you.
15. Supplement Magnesium Wisely
Due to depleted soil nutrients and certain medications, many people are magnesium deficient. Consider supplementation, choosing magnesium citrate for constipation or glycinate/threonate for sleep/mood.
16. Take Vitamin D Supplementation
Most people, especially those with less sun exposure or darker skin, need Vitamin D supplementation as it’s vital for health.
17. Focus on Healthspan, Not Just Lifespan
Aim to optimize your ‘healthspan’ (years lived in good health) by making conscious lifestyle choices, as overall lifespan may be increasing while healthy years are declining.
18. Practice Pre-Mortem Thinking for Health
Imagine receiving a severe health diagnosis and reflect on the lifestyle choices you would wish you had made. This can be a powerful motivator for preventative action.
13 Key Quotes
For every year that you have poorly controlled type 2 diabetes, you're losing 100 days of life.
Dr. David Unwin
Maybe a third of all the people in the world with type 2 diabetes don't even know they have it.
Dr. David Unwin
Insulin, the hormone insulin produced by your pancreas gland, it pushes the sugar and it pushes it out of the bloodstream inside cells where it can be used for energy for you to run around. But what if you take in more carbohydrate than you need to run around? Well then, that sugar is turned to fat inside cells.
Dr. David Unwin
Fatty liver interferes with the good work of insulin. So you develop a thing called insulin resistance, which means your insulin is no longer as powerful as it was.
Dr. David Unwin
Starchy carbs as actually glucose molecules holding hands. And then digestion comes along and breaks down they're not holding hands anymore and they become free sugar again.
Dr. David Unwin
What they're actually addicted to is the sugar.
Dr. David Unwin
If you have a normal blood sugar, I would like you to guess how much sugar is there in my entire blood system. ... That is all there is. One sugar cube.
Dr. David Unwin
The more carbs you eat, the hungrier I become.

2 Protocols
GRIN Model for Behavior Change
Dr. Jen Unwin (described by Dr. David Unwin)- Goals (G): Define your health goals specifically, focusing on what difference they would make to you in a year's time.
- Resources (R): Identify past actions or existing strengths that have worked towards your goals (e.g., consistency, social support).
- Increments (I): Determine small, realistic steps you can take today towards your goals, reducing the size of success to maintain momentum.
- Notice/Reflect (N): Pay attention to and reflect on the positive feelings and benefits you experience when things are going well, linking actions to self-esteem and identity.
4-Step Plan to Break Food Addiction
Dr. David Unwin- Honesty: Acknowledge and be honest with yourself about the problem and whether there's an addictive potential with certain foods.
- Specific Foods: Identify precisely which foods are problematic for you.
- Plan for Abstinence: Develop a clear plan for complete abstinence from those specific foods, rather than attempting moderation.
- Share with Loved Ones (with caution): If helpful, share your plan with supportive loved ones, asking for gentle support and tolerance, not policing or judgment, to avoid deceit and isolation.
