I tried browsing through other posts on this topic but decided to make a new one since I'm actually more confused now.
For a while now I have been getting sudden heart palpitations (about 4 months), after starting to increase my carb intake, mostly from fruits, and following the other guidelines while listening to my body, I've actually seen improvements in the number of episodes. I used to get dizzy after doing a very light workout too; that has improved as well. That made me conclude that my cardiovascular system is improving (after a few months of very low carb and very low calorie; which I'm thinking burnt out my adrenals and slowed my thyroid function).
The latest episode happened after my dinner. I also measured my body temperature which was lower than I wanted it to be but still not the lowest it goes during the day (36.7C, it usually goes from ~36.5 in the morning to ~37.3 with drops mostly after meals...which I blame on a low stomach acid and digestive issues).
I also considered blaming it on mineral imbalances, specifically calcium and magnesium, but given that the symptoms are a bit hard to read I'm having difficulty figuring out which one's out of balance (I take a 200mg magnesium supplement and a tsp of eggshell for calcium on top of everything else I eat). I have also increase my salt intake considerably; but still nothing more than my palate desires.
Also I'm not feeling anxious or stressed in anyway, I actually feel a bit relaxed...though my muscles feel a bit weak in general, and a few twitches here and there.
I know there are many more explanations for what's happening but anything in the way of help or suggestions in what I could experiment.
btw, I'm a 29 year old male.
