Hi, I’ve been doing keto for one month now and its going pretty well, feel OK and lost about 7 kg (from BMI 28.1 to 25.9). Don’t feel hungry, have some great recipes and measure my blood sugar and keto levels regularly with a Keto Mojo JKI, especially in the beginning.
glucose levels between 3.5 and 5 mmol/L
ketone levels between 1 and 3 mmol/L
So, seems pretty OK from what I have read online. However … I have very limited energy for exercising. I like to do some cycling but after two weeks on keto I did a 65 KM ride and totally bonked after about an hour (30 KM). I have bonked before on carbs as well but this was absolutely next level.
Got home and measured my glucose and keto levels (twice)
glucose 3.7 mmol/L
ketones 2.6 mmol/L
After eating something (think a salad with chicken, bifi saugage, feta and dressing) I felt really tired and not very well but thought it was because of the bonking. Measured about two hours after eating my levels again
glucose 3.8 mmol/L
ketones 7.3 mmol/L (really high)
So, didn’t do any more cycling but started to do some running, no joy there eighter, after just 4 KM a really quick drop in energy and needed to walk. Normally (like a year ago) I could easily run 12 KM in an hour but OK a haven’t done a lot of exercise the last 8 months. Tried a few more runs and got up to 8 KM but always have to stop halfway for a bit of rest and stretching, very frustrating. The strange thing is also that my heartrate goes trough the roof even though it doesn’t feel like it. My max is about 195-200 but on this very short run it very quickly goes to something like180 … crazy.
OK, so today, day off from work, finally some nice weather so on the bike I went … same route (with less wind) and started relaxed. Everything OK up to 55 KM and started to feel the energy go, slowed down and did the last 10 KM really easy. Got home, felt tired but had not really bonked so great. Measured my glucose and keto again (twice) and
glucose 2.3 mmol/L (very low)
ketones 4.4 mmol/L
What the $%%#@, WHY ?.
I didn’t feel too bad but after eating some yogurt and an egg salad I started to feel pretty bad, just as the last time after cycling so I measured my glucose and keto again.
glucose 4.1 mmol/L
ketones reading said HI, that means I believe above 8.0, so crazy high
So, after this massive text … anybody knows what wrong with me and why can I not do any ‘endurance’ exercise (endurance between quotes as 60 KM cycling or 8 KM running is not really endurance). Is this normal when you start keto, am I not yet fat adapted … any help, explanation, solution would really be appreciated, THANKS !
