A keto diet can be dangerous for people with type 1 diabetes because it can cause high blood sugar levels. People with type 1 diabetes need to be very careful when they change their diets, and they should talk to their doctor before starting a keto diet.
Individuals with a high risk for heart disease should also avoid this diet, as it can cause complications down the road.
A keto diet can also be hard on the kidneys, so people with kidney disease should avoid it. It’s always best to check with your doctor before making any changes to your diet.
