While it’s possible to stay in ketosis for an extended period, the long-term effects of maintaining a keto diet indefinitely have not been well-studied. Some individuals may experience nutrient deficiencies, gastrointestinal issues, or difficulty maintaining the diet’s restrictive nature over time. It’s also not the most heart-healthy diet. It’s essential to work with a healthcare provider to ensure balanced nutrition and address any potential health concerns if you choose to follow a keto diet in the long term.
