There are several versions of the ketogenic diet, including:
- Standard ketogenic diet (SKD): This is a very low-carb, moderate-protein and high-fat diet. It typically contains 75% fat, 20% protein and only 5% carbs (1Trusted Source).
- Cyclical ketogenic diet (CKD): This diet involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
- Targeted ketogenic diet (TKD): This diet allows you to add carbs around workouts.
- High-protein ketogenic diet: This is similar to a standard ketogenic diet, but includes more protein. The ratio is often 60% fat, 35% protein and 5% carbs.
However, only the standard and high-protein ketogenic diets have been studied extensively. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes.
The information in this article mostly applies to the standard ketogenic diet (SKD), although many of the same principles also apply to the other versions.
Diabetes is characterized by changes in metabolism, high blood sugar and impaired insulin function (27Trusted Source).
The ketogenic diet can help you lose excess fat, which is closely linked to type 2 diabetes, prediabetes and metabolic syndrome (28Trusted Source, 29Trusted Source, 30Trusted Source).
One study found that the ketogenic diet improved insulin sensitivity by a whopping 75% (29Trusted Source).
Another study in people with type 2 diabetes found that 7 of the 21 participants were able to stop using all diabetes medications (28Trusted Source).
In yet another study, the ketogenic group lost 24.4 pounds (11.1 kg), compared to 15.2 pounds (6.9 kg) in the higher-carb group. This is an important benefit when considering the link between weight and type 2 diabetes (2Trusted Source, 31Trusted Source).
Additionally, 95.2% of the ketogenic group were also able to stop or reduce diabetes medication, compared to 62% in the higher-carb group (2Trusted Source).
