How intermittent fasting affects eyes and vision?

Let’s start by looking at one of the biggest causes of poor vision—diabetes. When you’re a diabetic, there are four main issues that are affected: kidneys, heart, nervous system, and the eyes.

There’s actually a condition caused by diabetes called diabetic retinopathy. This is damage to the retina. There’s also a chance of developing glaucoma when you’re a diabetic. When you have a blood sugar issue, it destroys the tiny vascular system that goes to the optic nerve. This can cause blindness. We also have another problem called macular degeneration. This is another situation where you have poor circulation in the back of the eye.

And finally, we have the common issue of cataracts. Cataracts are very common in diabetics. What these all break down to is insulin resistance. So if insulin resistance is a cause of poor eyesight, then doing the opposite could help reverse the damage and help improve eyesight. Intermittent fasting is fantastic for insulin resistance. It helps normalize your blood sugar, and it helps your body run on ketones, which also helps with blood sugar levels.

In addition, fasting helps stimulate autophagy. Autophagy is when your body starts to clean up old damaged proteins. This could be floaters in your eye or scar tissue in the eye.

One last note, if you start keto and intermittent fasting and your experience worse vision, all this means is that you are not yet adapted to keto. Give it some time.
