- เผยแพร่เมื่อ 5 ก.พ. 2025
- Dr. David Unwin is GP based in Southport in the United Kingdom. After 25 years of attempting to treat diabetes by conventional methods, Dr. Unwin stumbled upon the website for patients with diabetes - www.diabetes.co.uk
From this revelation, Dr. Unwin now ignores official advice and treats his patients with a low-carbohydrate diet. Since adopting the approach, his practice now spends £45,000 less each year on drugs for diabetes than is average for his area.
Dr. Unwin is the RCGP National Champion for Collaborative Care and Support Planning in Obesity & Diabetes, as well as a Clinical Expert in diabetes. In 2015 he won the North West NHS ‘Innovator of the Year Award’ and in 2016 he won the National NHS 'Innovator of the Year Award' for his work in treating diabetes with a low carbohydrate approach.

there is something about this man that seems so honest.
Not so much. I wouldn't want to be his patient, and he wouldn't want me. He would probably throw me to the lowest status, most inexperienced physicians who would be stuck with me. Physicians have a lot of cruelty and injustice to answer for.
Yes. I think it is his honesty and humility that makes him so terribly attactive.
Have you ever thought about all those seemingly honest politicians you have voted for only to be disappointed by their lies later.
Thank you, for explaining everything. I am a 55 year old female, who owns her own cleaning business. I work alone 4-5 hours M-F.... while I work, I listen to Drs conference, meetings, etc. I have learned loads of amazing information! I listen only to nutrition related things, low carb and such. Blessings to you, you have saved so many lives, mine included!
😊😊😊😊😊😊
If only all Dr were like David Unwin, Thank you Dr
Dr Unwin has been my G.P. here in Southport for many, many years and I have been truly blessed by this. He helped me to understand about adopting a low carb lifestyle to remedy too high a level of blood sugar instead of just following the then usual NHS route of putting me on a drug regime. I'm so very grateful for this. Thank you.
What a lovely man with an inspiring message of hope.
I enjoyed this talk SO much. As I learned about this after I retired as a surgeon. I would have been a much better doctor had I known this before. It really is so simple. I was a 1st year medical student when Dr. Ancel Keys Ph.D. (physiology) made the cover of TIME. He was head of his own department (Physiological Hygiene) at the U of Minnesota and was not in the medical school but in the school of public health
Oh, my. And it all changed with Dr Keys. Incredible once you know the history .
Brilliant. It is so good to see a GP who is open and honest and willing to open his mind to new possibilities and then put it into his everyday practice. The presentation was clear, concise, easy to watch and understand. I am sharing this one far and wide. Thank you.
Dr Unwin, you are absolutely amazing, kind, funny and informative. Wish there were more doctors who had the same outlook on working with their patients! Thank you!
Your sugar infographics are an eye opener to everyone that sees them! Thankyou for all the work you do and for the passion you have.
I started measuring blood sugar after certain foods a year ago. Watching this lecture just confirms what I learned myself. Standard medical advice is woeful. If I eat rice my blood sugar spikes between 9-11. If I eat eggs and meat my blood sugar stays around 5.5- 5.6. Even beer which we are told is liquid bread and high sugar has only a slight impact on my blood sugar taking it up briefly to around 6.2-6.4. I haven’t tested what more than 4 pints does to my blood sugar because since switching to low carb on the odd occasion that I do imbibe I cannot drink more than that. Previously in my high carb days I could drink beer all day and could never have enough, now my body just switches off the craving so quickly that I don’t want anymore. Yes I am claiming that a low carb or even better a carnivore diet stops cravings for alcohol.
After experimenting with LCHF and OMAD I switched to carnivore I have now been carnivore for 6 weeks and feel 20 years younger. This kind of information needs to get out there and I wholeheartedly recommend getting a blood sugar kit and testing your sugar after each meal. You can then start eliminating foods that trigger high sugar. Once you’ve done that assess how you feel, no doctor or dietitian knows how you feel better than you do.
I have also found that I don’t crave nearly as much beer on keto😎
The higher the fermentation in the beer, the less impact on blood sugar. Obviously, the liver still has to work on the alcohol.
Wow! If only all GPs took this approach.
You're the type of doctor I'd like to have. Thank you very much.
You're awesome Dr. Unwin!!!!
I wish you could train your colleagues in the US 💯
I'm a diabetes management coach in the US and I hear everyday from patients "my doctor told me i don't have to check my sugar but they gave me metformin and glipizide". And my eyes want to come out of my head and I tell them "well how will you or your provider know if the medication or your nutrition is working for you if you are not testing? Why should you have to wait until your next A1C draw to see results? The good thing is you don't need their permission to test, you can buy a meter at the pharmacy or Walmart for $11 and a set of strips for $20. Go get yourself a meter, start checking it, and let the number guide your nutrition choices!!!"
I get great success with my patients 💯
I also love how you re-frame the mindset away from fear based thinking to more goal oriented thinking ❤
I do this too with my patients 💯
What a Excellent Presentation!..
Brilliant presentation Dr Urwin. We need examples of healthy meals alternatives
The equivalent in starch of 21 teaspoons of sugar for breakfast... that's nearly half a cup of sugar! With the marmalade, or a 2nd slice of toast... that 'typical English breakfast' could easily be much higher. Time to bring back bacon & eggs, steak and egg, ham and eggs... for breakfast! Or skip breakfast and have low carb, nutrient dense meals for lunch and dinner.
That's the idea, it'll last you the whole day.
Americans are thinkg wtf ... a doctor that doesn't get a kick back ... what's that all about?
Is there a GP of the year award?
If not, there ought to be, and we have just listened to the obvious prime candidate to receive that recognition.
@@Jefferdaughter A year on. All you can do is share and suggest. Only today I have shared this and suggested it. Maybe I am not doing a good enough job, it mainly falls on deaf ears and I see people suffering when they could be free.
@@Michael-4 It sems some people just prefer their bad diet too much to change.
Give it to someone who doesn't throw the hardest cases to the most junior physicians. Uncaring to say the least.
In my language t2d is called sugar sickness. So accurate. However, I have yet to meat an MD who treats sugar sickness with dietary adjustments.
Thank you so much
Dr. David, for all the good amazing informations for our good health ...
awesome job
Awesome presentation.
glad for the tribe too
Dr Unwin. You are such a really sweet humble man. Lucky wife.
hey, lovely vid
I would like a copy of the sugar spoons chart . Does anyone know where to get it please?
Amazing presentation Dr.
Has anyone heard where we might obtain that book or chart of glycemic index = to teaspoons of sugar?
So inspiring. Well done.
Diabetes is a $19 billion/yr industry in the US. They have no interest in curing diabetes.
clever doctor so helpful thanks
How can I download a copy of Dr. Erwin's sugar chart ?
Thank you, very inspiring. Will let someone know who has T2D. How low of carb? Are some people better with real food carb (read of type EO4/4 )? Does this help type D1 people? Read high cholesterol can be thyroid related. Wish more Dr's would listen to people (patients)!
Great talk, what a great GP!!
Wonderful man.
Thank you so much.
Thank you
Table sugar is half fructose, which is NOT measured by blood GLUCOSE tests. That's why it is lower on the glycemic index than whole grains. Starches are chains of glucose only. As a physician, you should have known this.
Queen Elizabeth , please recognize his worth and knight him. If England could be the forefront of dietary education, America would be in your graces.
Can you lose weight and therefore reverse type 2 diabetes on an animal based diet? I don't doubt it, but I've yet to see a long living population do well on a diet high in animal foods in later life...
Noakes, Westerman, Phinney, Volek.... and many others are doing the work. The truth is out there.
Eskimos. Pure protein and fat
Luca have you seen any doing well without Animals. I dont think there are any
The Inuit and people like them couldn't possibly have ever had type 2. After all, as the good Doc said, it used to be called SUGAR diabetes years ago. There's no sugar in meat and fat.
It's a waste of time to discuss lo carb with your doctor unless you know he is sympathetic to the cause. Most docs are just not interested or even anti lo carb . You need to publish a a National list of doc practices that believe or promote lo carb and then you can find the right doctor.
A1C is NOT all that accurate. There are many factors unrelated to blood sugar that affect it, like undiagnosed/poorly treated Hypothyroidism. In addition, glycation of red blood cells is BOTH dependent on their age AND blood sugar levels combined. For example, if your red blood cells tend to live longer, you will get an A1C HIGHER than your average blood sugar really is. BTW Do NOT assume your patients are too stupid to understand technical terms.
Robin Lillian glucose tolerance test maybe a alt choice

To all Keto zealots please read this and then watch Biolayne’s various videos about Keto, Carbs, Insulin … unless of course you don’t want to challenge your own confirmation bias:
A food's GI ranking only applies when a food is consumed on an empty stomach without any other type of food. As anyone who's ever eaten food knows, this isn't always how we eat.
Pair a high GI food with a lean steak or a piece of salmon, a side of broccoli and a salad with vinaigrette, and the protein, fiber and fat all will serve to lower the glycemic index of the meal.
In addition, the glycemic index doesn't take into account how much we're actually consuming. The GI value of a food is determined by giving people a serving of the food that contains 50 grams of carbohydrate minus the fiber, then measuring the effect on their blood glucose levels over the next two hours.
A serving of 50 grams of carbohydrate in one sitting may be reasonable for a food such as rice, which has 53 grams of carbs per cup. But for beets, a GI ranking of 64 is a little misleading since beets have just 13 grams of carbs per cup; we would need to consume nearly 4 cups of beets in order to cause that spike in blood sugar levels.
An Alternative to Glycemic Index
Glycemic load, or GL, is a formula that corrects for potentially misleading GI by combining portion size and GI into one number. The carbohydrate content of the actual serving is multiplied by the food's GI, then that number is divided by 100. So for a cup of beets, the GL would be: 13 times 64 = 832 divided by 100 = a GL of 8.3.
As a frame of reference, a GL higher than 20 is considered high, between 11 and 19 is considered moderate, and 10 or less is considered low.
The bottom line: Even though the glycemic index isn't a perfect system, it can be a useful tool to identify lower-glycemic foods that often are more nutrient-dense, as well as what foods are higher in refined carbohydrates.
Nice opening, an ad hominin attack. Really says a lot about what you think. Did you even listen to what Dr. Unwin had to say, or did you just decide to chip in with your own bias?
If conformation bias is actually seeing results, then I can confirm I have a bias based on my own personal outcome.
According to Bart Kay the glycemic index is very inaccurate. He shows evidence.
A food having a high glycemic index doesn't prove that they cause diabetes. Before asian countries started to reduce there high rice diet they had some of the lowest rates of obesity in the world. A gram of fat has 9 times more calories than a gram of starch, excess energy, esp. In the form of fat contributes to body fat, whereas glycogen is easily burned off. A high fat diet, which is a high calorie diet is the main contributing factor to excess body fat in the adipose tissue, which overflows into the bodies cells and disrupts the cells communicating capacities to enable insulin to transport glucose into the cells.
Actually, Luca, this theory has been proven inaccurate, or at least incomplete, over and over. Humans are not simply machines, but biological beings. The ingestion of sugars, which includes starch, triggers a cascade of responses in the body, including spiking insulin. If this occurs repeatedly, or constantly, over time fat results. Insulin also blocks the burning of either currently ingested fat or body fat stores.
Ingesting fat, on the other hand, does not cause insulin to spike. In the absence of insulin spikes, the body will switch to burning fat for fuel. If there is more than is needed, the body will kick off extra through the breath and/or urine. The ketones (form of fat the body burns) can be measured in both breath and urine.
AND fat is also crucial for body structures, as well as forming hormones (to regulate many body processes), and forming and/or transporting crucial vitamins, including Vit D. The brain is about 80% fat and 30% cholesterol. About half of the membrane of each cell is made of fat, nerve sheaths, etc.
Sadly, the public is unaware that there is zero dietary requirement in humans for carbs of any kind. And no structure in the body is made from carbs. But when carbs bind to proteins in the body, they are permanently degraded, at least until those cells die.
@@Jefferdaughter Biologicals are machines, very complex machines with hormonal regulation of substrates.
The rest of the story on the Asian population is that even before they began to be "westernized" in their diet, they had a low incidence of obesity, but a relatively high rate of diabetes. According to the Harvard School Of Public Health, today Asia accounts for 60% of the worlds diabetic population.
David presents Dishonest and inaccurate science. Our body uses insulin to transfer glucose from our blood stream into our cells to be turned into ATP which is used as cellular energy. When you eat diet high unrefined starches, which are the ideal energy source for the human body, because it provides slow release, low calorie, low toxicity fuel... A starch based diet with fruit and veggies, you can eat until you are full, maintain an ideal body weight, have lots of energy, have good bowel movements, and not have to fast, drink coffee like those on a high animal fat diet...
Luca, we were all taught that starches are released slowly, but starches are simply chains of glucose that quickly become unlinked when eaten - and are then just sugar.
Dr. Stephen Phinney, PhD (internal medicine & nutritional researcher) and Dr. Jeff Volek, among others, have talks on TH-cam that cover how ketones from fat burn much 'cleaner' than carbs do. The original research these two scientists have done on this topic has led them both to switch to nutritional ketosis. Phinney has been in constant ketosis (NOT ketoacidosis!) for over 13 years. Volek for 6 or 7.
Neither of these researchers fast.
No one 'has' to drink coffee, but most enjoy it. Even many humans trying to be herbivores. 'Paleopathology and the Origins of the Paleo Diet' by Dr. Michael Eades is an interesting look at the effects of plant-based vs animal-based diets on human development and health.
There are many other researchers doing similar work with similar findings which are readily available.
Just wondering... how do you plan to get the other animals on the planet to stop eating each other?
This sort of comment has nothing to do with the science or any form of objectivity. Met my first vegan recently, the almost religious furfore they made of the diet was sad. My guess : this is written by someone in that mindset.
@Luca M Dishonest and inaccurate science? I see evidence based - hence the charts and tables that anyone with a basic understanding of arithmetic, let alone statistics can understand.
You did actually watch the video before you started frothing didn't you?
Do you have a medical degree?
Are you a qualified Dietician? (not a nutritionist - anyone can call themselves a nutritionist see Gillian McKeith who had to stop referring to herself as Doctor).
Do you have a vested interest in diabetes drugs or maybe a bakery?
Put up or shut up.
I can eat gluttonously until full on high animal fat, am barely gaining and consistently blow a 0.16 bac% despite being stone cold sober.
