Can an online program on a low-carb diet help people reverse type 2 diabetes?

Does an online program that teaches a low-carb diet to adults with type 2 diabetes work to help reverse the disease? And if so, how well?
In this new study of the Diabetes.co.uk low carb program, the 1-year results are presented. They tracked 1,000 participants who took part in the program, a digitally delivered 10-session educational intervention for glycemic control and weight loss using a low-carb diet:
Especially for participants who fully engage, an online program that teaches a carbohydrate-reduced diet to adults with type 2 diabetes can be effective for glycemic control, weight loss, and reducing hypoglycemic medications….
For example, participants with elevated baseline HbA1c (≥7.5%) who engaged with all 10 weekly modules reduced their HbA1c from 9.2% to 7.1% (P<.001) and lost an average of 6.9% of their body weight...
The results are quite good. Not quite as impressive as those of Virta Health, but the latter is a close to $400 dollar per month intervention while the low-carb program is only £30 ($38).
Regardless of the slightly different approaches, these two companies both demonstrate how it is possible to safely and effectively start reversing type 2 diabetes using a low-carb or keto intervention.
Another even more affordable option to do so is to use our Diet Doctor guide, recipes and our two-week get started challenge etc. It’s all free, forever.

I've had a subscription a couple of months but as a pensioner it's money I really need to live, so in return for all the free information, recipies and videos I recommend Diet Doctor wherever I can. I have a few Facebook Keto pages where it gets mentioned all the time.
Hope that is enough
