A keto diet is usually very safe. However, in the following five situations, you may need extra preparation or consultation with your doctor:
- Are you on medication for diabetes (e.g., insulin)?
- Are you on medication for high blood pressure?
- Are you breastfeeding?
- Do you have any thyroid problems?
- Do you have any liver problems?
If you’re not in one of these situations, you’ll likely do fine on a keto diet without needing any special modifications.
