The keto diet is a low-carb, high-fat diet. It lowers blood sugar and insulin levels, and shifts the body’s metabolism away from carbs and towards fat and ketones.

Base the majority of your diet on foods such as meat, fish, eggs, butter, nuts, healthy oils, avocados and plenty of low-carb veggies.

Certain supplements can be beneficial on a ketogenic diet. These include exogenous ketones, MCT oil and minerals.
