Ketosis even when not fasting or beginning of fast.

Not sure, but I'm already very thin, and when I fast or do intensive excercises, (I run distance) when does ketosis come into being.
I live on a very low CR restriction diet, run, cycle and keep myself in a semi-fasting state. So when I either/and fast, run very long distance, is my body moving into ketosis, or is a false state?

I went on a long run earlier, near the beginning of a w/e fast and was totally drained, almost couldn't stand. After a few mins, of walking, I started to run again, somehow some energy returned, and could run the last 5 miles needed to get back home, so is this ketosis kicking in?

Once your body is used to transforming its metabolism to ketosis, dear Marsh, you should be able to convert quite easily... whenever energy demand is more than what the diet supplies. Indeed most people are in ketosis by the end of a marathon.

What you describe is most likely a switch to ketosis, yes.

Thank you Doctor and Marsh if you don't have any fat reserves then your body will use up muscle instead and (please correct me if I am wrong Doctor) you can tell if this is happening by the breath.

When running a marathon, I do feel it around mile 21-22, used to be 18 when I was training normally.
Me and a friend have a BMI about 16, train twice a day, live on a cr diet, normally, unless fasting and just live on fruit, salads, veg, etc.

When doing a long run earlier, we felt short of breath and a stage, we know that is when the body is in ketosis, but then we have to adjust pace so that we don't completely flake out. There is a stage later on when there is energy returns, even get a fast pace going just to increase temp, persperation and heart rate and get a base figure if we're cannabalising muscle for energy - as a result strength would drop, but weight would, so a trade-off is happening. We need to see what level ketosis we can manage.

Unfortunately dear David, muscle breakdown products do not typically have a pertinent smell.. it's the fat (ketones) that is most typically identified.

Dear Marsh, if you want to be really sure you could of course do a urine dipstick to identify ketones.. not too many people know exactly what it smells like.

Perhaps you should get yourself one of these body composition measuring scales or handheld devices using body impedance; they are not always very accurate but they are quite precise, so you can trust the changes reported before and after a run..

I've got a scale that does such readings. Not sure how accurate it is, but noticed today went on long run and ran tempo near the end - as fast as we could managed without sprinting and keeping it up. It was a few miles that I felt i was going to give up, fatigue was setting in, and breathing was getting hard, as I needed every bit of oxygen my lungs were producing, I felt my strength come from somewhere and kept it up until a couple miles later when we finished and puked from my stomach.
Wouldn't mind the body calipers, but it won't tell us more that we or I don't know

Indeed Marsh; calipers would unlikely be sensitive enough to measure the difference in one run whilst the electronic devices, although not necessarily accurate, may be sensitive enough to report a percentage difference before and after.

Likely puked because the blood was all going to the muscles and the stomach therefore rejected its content; it, too, needs blood to do its job!

Dear Marsh, please check out the following research:

International Congress of the Royal College of Psychiatrists (RCPsych) 2014. Session S40. Presented June 27, 2014.

LONDON ― Excessive exercising, or so-called "exercise addiction," is a real problem and often occurs within the context of eating disorders (EDs) ― although not always, according to a presentation here at the International Congress of the Royal College of Psychiatrists (RCPsych) 2014.

Question: Proponents of water fasting say that the juice during juice fasting inhibits ketosis. Is this correct, or does ketosis occur when juice fasting, only more slowly? Also, what do you think about the concept of "juice feasting?"

Dear Aspen, thank you for joining the forums. Please read widely, as I have addressed this topic many times in the forums. But in a nutshell: ALL fruit is juice by the time it reach your stomach. Thus there is no such thing as a "juice fast". It is a "fruit diet" to be correct. You can live on fruit alone and indeed it can be a feast.

Remember once more: whenever TASTE crosses your palate, your brain controls your metabolism as in any other eating person. It is not a fast.
