Studies show that people with type 2 diabetes can lose weight and lower their blood glucose levels by following a keto diet. In one study, people with type 2 diabetes who followed a keto diet for a year lost weight, needed less medication and had lower HbA1c levels.
People with insulin resistance, i.e. high blood glucose levels because the body does not respond properly to the hormone insulin, may benefit from dietary ketosis because it reduces the amount of insulin needed and released by the body.
There are few studies on the keto diet in people with type 1 diabetes. One small study suggests that it may help reduce HbA1c levels in people with type 1 diabetes, but more research is needed to get a full picture of the effects of this diet.
Remember that most studies only look at the short-term results of the keto diet. We don’t know if this is the way to manage diabetes in the long term.
If you are going to try the keto diet, be aware that it can be difficult to implement. The very low carbohydrate content is a big change for many people. You may feel tired for a few weeks while your body adjusts. To be successful, it’s a good idea to regularly stock up on keto-appropriate meals and snacks and plan your meals accordingly.
Is the keto diet safe if I have diabetes?
It depends on the type of diabetes. Generally, people with type 2 diabetes who are overweight think it’s fine and safe; if you have type 1 diabetes and want to try the keto diet, you should definitely consult your doctor first. Their health should be carefully monitored and signs of ketoacidosis should be watched for. In all cases, a change in medication may be necessary and should be discussed with your doctor.
The keto diet also has some side effects that need to be considered.
Hypoglycaemia: although the diet can lower HbA1c levels, it also means a higher risk of hypoglycaemia, especially if you are taking diabetes medication. If you are going to try the keto diet, inform your doctor or diabetes educator. They can advise you on how to measure your blood glucose, how to take your medication and what to do if your blood glucose is too low
