Looking back now I absolutely blame the dinner, I ate mashed potato and some dessert after keto but obv I didnt know at the time it was RH cus its never happened in my life and im 34, I just thought it was now getting use to running on fat and didnt like the change so quickly. The timing could of course be a freak coincidence but I highly doubt it. I felt fine in myself before lowering carbs. I took carbs out and tbh I felt good, I was exercising daily and felt energised and was fasting 16 hours a day no problem, didnt particularly enjoy the diet as Im not a big meat guy but my body clearly didnt mind it as its refusing to go back. I also read on a keto forum that the body can mimic diabetes or glucose sparing and make itself insulin resistant to make sure your muscles dont use what little glucose you have and instead saves it for your brain. Ive also read in places that if you improve your insulin sensitivity you can improve RH but others seem to suggest its just stuck with you. I can eat a good 150g of complex carbs a day as long as I spread it out without having a hypo but even without the hypos I feel really fatigued, muscle weakness, eyes feel strange, headaches etc. I am going to follow up with my GP when he comes back off holiday cus the locum just told me to stop eating junk and get on with it but im really not happy with that as a diagnosis
Yeah, looking at the meal you had,, I can really understand why the reaction happened, potato in any form is far too high in starch (high carbs) and will certainly cause the trigger for the excess insulin. The mash is made up of crushed potato, butter or milk, stirred into a mash. This concentration of starch is bad for me!
If you do have a good intolerance, for example, you do spread what carbs you do have and the good fats will help with suppressing the glucose spike, then that is fine, but be careful which carbs you do have cos even though the gms do matter but the make up of the carbs can be different even tho the gms in carbs is the same. For example, potato 20g can be a worse result than 20g of rice or pasta.
The mimicking of diabetes is not surprising as it clearly has so many similar symptoms. But it is non diabetic cos it is not hyper-glycaemic, it is hypo-glycaemic! And the best way to differentiate, between diabetes and hypoglycaemia is hypoglycaemia is too much insulin. With diabetes it is the opposite.
You can have insulin resistance, insulin levels that course through your blood, that can make you ill, high circulating insulin levels. Hyperinsulinimia is a part of RH unless controlled. Insulin that is not used goes to your liver and eventually causes fatty liver problems.
I have constantly come up against this notion of you must have carbs or glucose for good brain function.
That for myself is total bs!
When I was having a fasting test in hospital, before the test, my brain had been numb and dumb for years. Brain fog lasted all day every day! After a couple of days my brain became clear, like a veil lifting from my concious. I couldn't believe my energy levels, after so long being tired always!
My body can cope for days without food. And nothing happens! But I only eat mid afternoon and before 7pm! That is what I have realised helps me get through this last decade since diagnosis!
We all eat too much anyway!
Hope this helps!
Keep asking!
