Re: eyes vessels red and heart palpitation increase in third day

OMG stop the fast! Please please please, you can seriously harm yourself if you keep on fasting.

I don't know your body type, but your height and weight indicate to me that you probably have a low percentage of body fat, which is where the health concern comes in. (I'm not even 5.1 and I feel perfectly healthy at 130lbs.)
From what I've read on wikipedia (probably the most trusted source I've read in regards to fasting), when your % body fat drops to around 10% while not eating, your body goes into starvation. You might think, but yeah, fasting is kinda like starving, but the difference is where your body is getting your calories from. For a woman with less than 10% body fat to fast means that your body will turn to muscles instead of fat to get the calories, and that means ALL muscles in your body will slowly be used up. That includes your heart. People who die from starvation generally die of cardiac arrest because their heart isn't strong enough to keep going.
Furthermore, most other things about fasting I've read specifically say to stop fasting if your heart starts to palpitate.

You seem to fit the criteria perfectly, and you're making me trust all the information I've read about this even more.

Note that you might have more or less than 10% body fat, that's just a ballpark or average figure. Your body might stop using fat for calories at something as high as 15% body fat, or even lower than 10%.

Regardless what your body fat is though, YOU SHOULD NOT FAST IF YOUR HEART PALPITATES. Even in full-out ketosis (how your body uses fat for calories), you will STILL be using up a small amount of muscle.

I don't have a good idea about your eyes though. Perhaps it's something from muscles in your eyes, or perhaps its just the fasting fixing something in them.

If you're keen on fasting, I suggest getting a doctor involved in the future for you just because you don't seem to have a lot of excess fat on you.

At the very least if you're still hellbent on fasting right this moment, get plenty of rest. Every year you hear of old people dying from heart attacks from shoveling snow: don't die from a heart attack while fasting because you feel you must keep on the go. Nothing strenous.
