For people with diabetes following a ketogenic diet, blood sugar monitoring is not just useful — it is essential for safe management and medication adjustment.
Fasting glucose (morning before eating): establishes your baseline. Post-meal glucose (2 hours after eating): reveals which foods affect you most. Pre-bed glucose: ensures overnight safety. Before and after exercise: physical activity significantly affects blood sugar on keto.
Fasting: 4.0–7.0 mmol/L (UK NHS guidance). 2-hour post-meal: under 8.5 mmol/L ideally. Pre-bed: 6.0–10.0 mmol/L.
If fasting glucose consistently below 4.0 mmol/L: medication dose likely needs reducing. If post-meal glucose consistently above 10 mmol/L: reassess dietary choices. Any readings below 3.5 mmol/L require immediate management.
Logging specific meals alongside blood glucose responses identifies your personal “safe” foods. Our keto salads and keto main dishes consistently produce stable glucose responses in most diabetics.
