Any of these signs could indicate that you are in ketosis:

  • Decreased appetite and increased energy levels
  • Increased thirst and urination
  • Keto breath, which may be more apparent to others than to yourself
  • Dry mouth or a metallic taste in your mouth

To ensure that you are in ketosis, you can always measure your ketosis level with ketone urine strips or ketone blood tests (which are more reliable). If you are checking ketone levels with keto urine strips, generally, dark purple color indicates the highest level of ketones.
