I did another pulse check on my ketones and it was consistently 0.3 mmol/L regardless of whether it was in a fasted state, 1 hour, 3 hours or 4 hours post eating. In my discussions with a few people in the know on LCHF there are a couple of theories as to why my ketones might me low these include:
- Not enough time to adapt. It can take some people 2 months to adequately fat adapt
- High protein content could be converting energy via gluconeogensis (if you are eating too much protien on a low carb diet you will convert protein into glucose through a process called gluconeogenesis, this raises your blood glucose levels… therefore you might as well be eating carbs!). A good range to aim for is 1.5 – 2.0 grams per kilogram of bodyweight, or 0.7 – 0.9 grams per pound. Given my intake was around 1.8 grams/kg/bw that's quite a lot given my size and suspect I should be leaning towards 1.0 to 1.2g/kg/bw.
- Not eating enough fat - this is not the case given I was clocking up > 70%
- Not enough sodium - Low-carb diets lower insulin levels, which makes the kidneys excrete excess sodium from the body. This can lead to a mild sodium deficiency.
- Eating too many carbs - this is not the case given my total carbs being less than 30g/day minus fibre, which is hovering around 20g/day.
So the likely reason is too much protein. Which is interesting as for 18 years I was a vego who ate a little fish. The increased protein would also increase my metabolism. Without further testing it's hard to give a definitive answer but is likely to be a case of too much protein.
