How To Use Food To Transform Your Health, Reverse Type 2 Diabetes & Improve Your Mood with Dr David Unwin #611

Jan 14, 2026 2h 22m 19 insights
If you have ever struggled with your weight, low energy, pre-diabetes or even type 2 diabetes, this is a conversation that could change your life. Dr David Unwin is an NHS GP who not only put his own type 2 diabetes into drug free remission, he has also helped over 150 patients do the same in a standard UK general practice – with ordinary people, on ordinary budgets, using food and lifestyle. It’s estimated that around 7/8ths of the adult population are metabolically unhealthy, which means that only a tiny minority of us are truly metabolically well. And this is a serious issue because poor metabolic health is one of the root cause drivers of insulin resistance, type 2 diabetes, cardiovascular disease, strokes, Alzheimer’s and many forms of cancer. In fact, this is one of the main reasons why I co-founded Do Health https://drchatterjee.com/do-health/ - a personalised health companion, powered by your individual biology and lifestyle - as a way of helping people improve their metabolic health early, well before they get sick in the future. In this week’s episode, we cover: The early signs of poor metabolic health, and why symptoms like fatigue, belly fat and brain fog are often overlooked. Why many issues we see as ‘normal ageing’ are actually signs of insulin resistance. How David himself reversed his own type 2 diabetes and, at the same time, improved his mood, energy and cognition. How reducing starchy carbohydrates if you have metabolic dys-regulation can dramatically improve blood sugar control Why so many of us struggle with bread, pasta, and ultra processed foods – and how food addiction may be silently driving our behaviour. The two women who helped David rethink everything he thought he knew about food, hope and healing And why it’s never too late to work on your metabolic health and why doing so can change every aspect of your life. One of the things I love most about David is his passion. He really is someone who genuinely wants to improve the health and lives of his patients and our hope is this conversation empowers you to make small changes that will improve your blood sugar, weight, energy, and ultimately, your future.   Support the podcast and enjoy Ad-Free episodes.

Actionable Insights

1. Consult Doctor on Medication

If you are currently on medication for diabetes or other conditions, consult your doctor before making massive changes to your diet, especially dramatically cutting carbohydrates, as medication doses may need adjustment to prevent adverse effects like hypoglycemia.

2. Reduce Starchy Carbs for Health

If you have metabolic dysregulation, type 2 diabetes, or pre-diabetes, reducing starchy carbohydrates (like bread, rice, potatoes, pasta) can dramatically improve blood sugar control and potentially lead to drug-free remission, as these foods break down into sugar.

3. Identify Blood Sugar Spiking Foods

Pay close attention to what you eat and how it affects your blood sugar. Identify specific foods that cause your blood sugar to spike and make a conscious effort to eat something else instead.

4. Check Your Belly Size

Measure your belly size as an early indicator of metabolic health. If your belly circumference is more than half your height, it may signal a problem with insulin resistance.

5. Recognize Metabolic Health Signs

Be aware of symptoms like tiredness (especially after meals), increased belly fat, brain fog, unexplained sleepiness, low mood, frettiness, circular thinking, fatty liver, or high triglycerides, as these can be early indicators of insulin resistance.

6. Prioritize Protein, Veg, Healthy Fats

Base your meals on protein sources like fish, chicken, eggs, or red meat. Add loads of green vegetables and healthy fats such as butter, olive oil, or full-fat mayonnaise to create a nutrient-dense diet.

7. Understand Food Sugar Equivalents

Be aware that many commonly eaten foods, even those perceived as healthy, have high sugar equivalents (e.g., 150g boiled rice ≈ 10 tsp sugar, a large baked potato ≈ 9 tsp sugar, a banana ≈ 5-6 tsp sugar). This knowledge helps in making informed dietary choices.

8. Explore Ketogenic Diet

For those with metabolic issues, adopting a ketogenic diet (under 50 grams of carbohydrates per day) can help lower insulin levels, enabling the body to burn fat for fuel, which can lead to significant health improvements.

9. Prepare for Keto Flu

When transitioning to a low-carb diet, be prepared for a temporary period of feeling unwell, sometimes called ‘keto flu,’ which can last up to a week as your liver’s enzyme balance adjusts to burning fat instead of sugar.

10. Identify Food Addiction

Reflect on your relationship with food; if you find yourself doing things you know harm your health (e.g., secret eating, intense cravings, inability to stop certain foods despite negative consequences), you may be experiencing food addiction.

11. Avoid ‘Cheat Days’ if Addicted

If you identify with food addiction, avoid ‘cheat days’ or occasional indulgences, as even a small amount of a trigger food can lead to intense cravings, rebound anxiety, depression, and a loss of control over your eating habits.

12. Consider Intermittent Fasting

Once your body becomes a ‘fat burner’ (e.g., through a low-carb diet), you may find you are less hungry and can comfortably eat less frequently, such as skipping breakfast and eating only once or twice a day.

13. Exercise in Fasted State

If your body is trained to burn fat, you can often exercise in a fasted state (e.g., running in the morning before eating) without needing to consume food beforehand, as your body will efficiently use stored fat for energy.

14. Use Continuous Glucose Monitor

If accessible, consider using a continuous glucose monitor (CGM) to gain real-time insights into how different foods and activities affect your blood sugar levels, empowering you to make personalized dietary adjustments.

15. Vegan/Plant-Based Low-Carb

If you prefer a plant-based or vegan diet, it is possible to follow a low-carb approach by being clever with food choices and finding suitable recipes, such as those available on resources like D-Life India.

16. Low-Carb on a Budget

To manage costs, be honest about current spending on junk food, which often equals the cost of healthier options. Utilize resources like the free Freshwell app for budget-friendly low-carb recipes and meal planning, and choose cheaper options like frozen fish or mince.

17. Learn Low-Carb Cooking

Invest time in learning how to cook delicious low-carb meals using alternative ingredients like almond flour or gram flour for baking and pancakes, ensuring you don’t feel deprived and can enjoy a varied diet.

18. Cultivate Health Curiosity

Cultivate curiosity about your own health and what works for you. If you observe improvements or unexpected wellness, explore the reasons behind them to further personalize and optimize your health strategies.

19. Avoid ‘Perpetual Autumn’ Eating

Recognize that the modern food environment, with constant access to high-carbohydrate foods, mimics a ‘perpetual autumn,’ leading to continuous fat storage without the natural periods of scarcity our ancestors experienced.
