The Diabetes Code by Jason Fung: This is a best-selling book by a Canadian Nephrologist (care and treatment of kidney disease) that explains type 2 diabetes in detail and recommends diabetics switch to a low-carb diet.
Counterweight Plus low-calorie diet plan: This diet was run as part of a scientific trial and showed promising results for obese patients with type 2 diabetes. Nearly half of the 300 patients in the trial reversed their diabetes. Note: the diet was run under the supervision of medical professionals and is not suitable for everyone: https://www.nhs.uk/news/diabetes/radical-low-calorie-diet-ma...
The Truth about Carbs: this is a BBC documentary from earlier this year which is unfortunately no longer available to watch on the BBC website. It featured NHS doctors who ran a two-week low-carb diet plan with type 2 diabetic patients. All patients reported improvements to their health, but the most impressive result was a patient with type 2 diabetes for 17 years who was now in part-remission.
