2/11 The study is by @lowcarbGP@jen_unwin + others and looks at reversing T2DM and pre-diabetes by lifestyle change, in particular by ⬇️sugar and starchy carbs
3/11 The study builds on the work of Prof Roy Taylor's DiRECT Study which found that *severe* calorie restriction could put T2DM into remission👍
More info here 👇 directclinicaltrial.org.uk
This was great news but SO many people find calorie restriction IMPOSSIBLE TO SUSTAIN 🤔🤷♂️
4/11 The study:
Carried out in "real-world primary care" in a *normal* #NHS GP surgery in 🇬🇧
128 people with T2DM and 71 with pre-diabetes volunteered to try a lower carbohydrate diet for an average of 23 months #LCHF
Some have been on it for 6 years (and counting !)
5/11 People were supported with normal 10 min GP appointments + some group consultations
A simple information sheet with basic advice on reducing carbs was given out
46% achieved drug-free remission of their diabetes. WOW!!
Ave ⬇️ in HbA1c was 17.5mmol/mol 👏👍
93% of those with pre-diabetes achieved remission 😲
But that's not all....
8/11
- Average BP ⬇️11/5mmHg so some BP meds could be stopped👍
- Improvements in total and LDL cholesterol 👍
- ⬇️ triglycerides 👍
- Average weight ⬇️ 8.3kg 👍
BUT weight ⬇️ correlated poorly with improvements in diabetes control 🤔
9/11 Of course, many medications for diabetes and BP could be stopped meaning that Norwood Surgery saves over £50k EACH YEAR on diabetes meds compared to local practices
Imagine how much money could be saved if practices across the🇬🇧and the 🌎did this 🤔🤑
⬇️ing sugar + starchy carbs delivers a real possibility of:
- Reversing T2DM + pre-diabetes
- Improved BP and cholesterol
- An effective solution sustainable for years (unlike severe calorie reduction)
Benefits of ⬇️ing carbs are INDEPENDENT of weight loss
11/11 Declaration of interest
This surgery is my own practice, Norwood Surgery in Southport. I'm so proud of what we've achieved. It's been a huge pleasure + privilege to to be a small part of this research led by my inspirational friend, trail-blazer + mentor @lowcarbGP

I've spent the last 10 years wondering about this. A TED Talk and paper by @segal_eran (refs at end) has completely blown my mind 🤯
He provides some of the answers - but they may not be what you think
Here goes....
2/11 The incidence of diet-related disease has ⬆️⬆️ in last 30 years
In 🇺🇸 70% of population are overweight, diabetic or have NAFLD (fatty liver)
38% are obese 😲
10% have type 2 diabetes 😲
Diet and lifestyle are the major drivers
3/11 So why don't we know what is the best diet for humans?
It's because we are asking the wrong question
Much of what constitutes the best diet depends on the individual human every bit as much the food
Nutrition needs to be personally tailored to each individual
2/8 I've been prompted to tweet about this after hearing some wonderful news today. A year ago @DrPaulaPowell1 and I assisted at a cardiac arrest on the beautiful but remote Isle of Lewis. David survived and posted a really moving video on FaceBook

As Diabetes Lead GP at my surgery for 25 years I achieved little/no success with @PHE_uk recommended "Eatwell Plate"
One day @lowcarbGP shared some success he had with offering LCHF (low carb, healthy fat) eating to people with type 2 diabetes
Does it work?🤷♂️
How? 🤷♂️

Important to understand if there's > 1 teaspoon (5g) sugar/glucose in your blood then insulin PUSHES it into cells where it is deposited as FAT and TRIGLYCERIDE
I’ve been “lent” a #cgm (continuous glucose monitor) so I’m fascinated to see what I can learn over the next 2 wks about how my life affects my sugar
I’m NOT diabetic or pre-diabetic and plan to monitor the impact of different foods and activities @grahamsphillips@Diabetescouk
1st observation is that application of #cgm is painless and adherence to skin is secure
Surprised my ave glucose is 6.3mmol/l
3 x glucose by finger prick finds #cgm over-reads by 0.9-1.5mmol/l (have allowed for 10min delay in #cgm but assumes sticks accurate) 🤔 @DrScottMurray
Effect of exercise: 50min hard interval session running in the pinewoods shoots my glucose up to 9.8 from 5.9 just before I set off. In <1 hour it’s back to 5.9
Conclusion: Exercise puts my sugar up. Surprised at this but @lowcarbGP noticed the same
