  • Low carb flu and blurred vision

    I've tried a few times to switch to Primal eating while keeping carbs low, at about 50-100g.

    Each time I try I quickly get headaches which I can cope with. However I also get a blurred vision around mid-afternoon. This quite worries me I end up eating carbs which does restore my vision quickly. However it sets me back and I can never fully go through the low-carb flu period and always go back.

    Has anyone ever experienced this? Any recommendations?

      I have expirienced this too, but it was mainly right after I ate a big meal, so I always attributed it to digestion and all the blood rushing to the stomach to help digest. I am no doctor, but that was just what I thought it might be from.

        Have you tried stepping down? Figure out where you're at and remove 50g of carbs per week. This might give your body some time to adjust.
