Adapted from Efficacy and safety of low and very low carb diets for type two diabetes remission. Systemic review and meta-analysis by Goldenber JZ et al. BMJ 2021;372:m4743
My comment: Now, we all know this, but there still is a great deal of resistance to the idea that cutting out sugar and especially starch from your diet, can put type two diabetes into remission. Lately there has been a lot more emphasis that very low calorie diets are good for diabetes remission, but let’s face it, starving yourself is no fun at all, and eventually, even if you do manage to keep to a very low calorie diet for many months, you need to do something to maintain that remission, rather than yo-yo back into diabetes. This is why I was pleased to see this report in the BMJ.
This study looked at randomised controlled trials that evaluated low carb diets for at least 12 weeks in adults with type two diabetes. Their definition was less than 130 g of carb a day or 26% of the diet from carbohydrates. A very low carb diet was defined as less than 50g of carb a day or 10% of dietary carbs a day.
They wanted to see if remission was achieved. This was deemed to be a HbA1c of less than 6.5% or a fasting blood sugar of less than 7.0 mmol/L with or without the use of diabetes medication. They also looked at weight loss, HbAIc, fasting glucose and adverse events.
Compared to control diets, low carb diets produced remission at six months in 57% versus 31% in the control diets.
The population studied were 1,357 people aged 47 to 67 years of age and most were overweight or obese. 23 studies were looked at and 14 of these included patients who were on insulin. There was very little in the way of adverse consequences.
