Jogging and Keto: Very High Pulse Rate

#1

Hi,

I am male and 47 years old, 187 cm tall and had a weight of 93 kg when I started with eating ketogenic six weeks ago (6.14 ft tall, 205 pound weight).

My aim is to loose weight in a healthy way.

Beforehand starting with keto I was doing sports regulary:

two times a week, one hour of jogging, pulse rate below 140.

When I go jogging now, I have a pulse rate of 173 after some minutes. This is my maximum pulse. I get scared because it seems too stressful for my body.

Is there anything I can do against this high pulse rate?

Perhaps eating some carbs before jogging? If yes, how many would be helpful?

Not sure how useful this is to you but Iā€™ve seen that my heart rate is significantly impacted by my hydration level. Doing cardio when Iā€™ve taken on less fluids than my normal results in my heart rate being 15-20bpm higher for the same intensity.

Biologically this makes sense, if your blood volume is reduced the heart has to increase rate to maintain same blood flow. I believe electrolytes will have similar effect.

Interestingly for me, if I didnā€™t have the heart rate meter showing me the difference I donā€™t think I would have been able to tell

I havenā€™t experienced the high pulse but when I forget my electrolytes supplements, I do get more exhausted more quickly.

These are the supplements:

Iā€™ve definately noticed this as well since starting Keto.
Iā€™m interested in hearing more opinions.
So far, I take a small break to drink water and let my heart rate come down, then carry on. It IS a little concerning when youā€™re used to having much more ā€˜staminaā€™ ā€¦

at least here
9m57s@Dr. Zeeshan Arain - ā€˜Why arenā€™t I losing weight on LCHF?ā€™
it is mentioned to ā€œtake some good quality carbons around the time of excerciseā€.

So my first idea would be to take some (full grain) cereals before jogging.

Maybe:

  • 50 grams
  • 3 hours before starting with jogging.

Would that make sense?

Today i noticed the same thing. I am doing keto since a while but i recently started to restrict protein.
I felt fine and normal and wasnā€™t sure if the HR measurement via the optical sensor of my watch is correct, but i exercised 3 times today and the numbers were pretty high on all of them.
I am used to pretty low numbers, i need to put some real effort into it to get to 160, but today i was easily over 160 and even above 170.
Not sure what to think of it but since i am feeling fine i am not concerned.

I was relieved when I read your post. For me to keep my heart rate below 135 when running, I need to be going at the speed of a brisk walk. I just thought I was unfit.

Thatā€™s perfectly normal, running is a lot more taxing then cycling for example.

some people take longer to fully switch to fat burning, back off a bit till your full energy returns

this is a good video on athletes and keto

Thanks for the link.

So, yes, in the last quarter of the presentation, he mentions the ā€œultra marathon runnersā€.

But what I do miss, is some concrete advice about what they eat to take these distances.

And are they all in the keto regime when they are running?
