DAY 18 - LCHF Road Test



Hooray I found a chemist that has my ketone sticks to use with my monitor.  Measuring your blood ketones is a far more exact and a reliable measurement compared to urine ketones using cheap dipsticks. Ketosis is of course the state the body is in when eating very low carb. Ketones, made from fat, will then fuel the brain instead of glucose.

So at 5pm I took my first ketone reading WHAT only 0.3 mmol/L. Man what does this mean? They say for weight loss you should be aiming for 1.5 to 3.0 mmol/L.  It means that insulin levels are very low. I also took my glucose levels and they recorded at 4.6 mmol/L which is pretty good.

So why then are my ketone levels so low when I've been following the diet religiously and without cheating?  And whilst I've only been blogging about it for 18 days I've actually being following it for 26 days so by now I should be in fat adaptation mode. You all know that I personally am not interested in losing weight. For me it's more about how my body is adapting it's choice of fuel for energy.

So does this mean I am not burning ketones?  I took it again this morning in a fasted state (so after 12 hours of not eating - post dinner to before breakfast) and it was exactly the same which makes sense to me in a fasted state but I would have expected it to rise throughout the day for my afternoon reading.  I've put my dilemma to the experts running chat rooms and I'm eagerly awaiting a response.  Maybe it's due to the fact that I don't have a lot of fat to burn so my body has become really efficient at burning what ever food hits my stomach.

In one sense I'm relieved as if this kind of diet isn't working for me it means I can go back to carbs hooray. To be honest I really feel this approach is far too restrictive and is definitely not for everyone. I can see how there are many benefits for those suffering with the metabolic syndrome or type 2 diabetes but if you're training hard physically then this is questionable if your performance is going to be compromised. There's also the debate of hormonal changes which I spoke about in my previous post.

I would love to get your thoughts on LCHF and whether it's worked for you and how long did it take you to get into fat adaptation.
