Symptoms, conditions and causes

What's the reason for short memory loss?

Short-term memory loss can create a lot of difficulties that make life harder. The area of the brain that is responsible for your short-term memory is called the hippocampus. Any type of damage to the hippocampus can cause problems with memory in general.


  • Asking the same questions repeatedly

  • Forgetting where you just put something

  • Forgetting recent events

  • Forgetting something you saw or read recently

Cause #1: Nutritional deficiency

There are several nutrients that are vital for the healthy functioning of the brain. If you are deficient in these nutrients, the hippocampus will be affected most. The good thing is that it can regenerate if you restore your normal levels of those nutrients.

-Vitamin B1 is a very important vitamin for healthy brain function as well as for your nervous system.

-Vitamin D has many health-related functions, including healthy development and upkeep of the brain. Out of all the brain areas that are affected by vitamin D deficiency, the hippocampus feels the deficiency most.

-If you are deficient in zinc (mineral) your hippocampus won’t work properly, resulting in a short-term memory problem.

-If your brain doesn’t have enough oxygen this can result in damage of the hippocampus.


  • Restore the necessary amounts of vitamin B1:

  • consume nutritional yeast

  • consume benfotiamine (fat-soluble B1)

  • avoid refined carbs and sugar

  • avoid consuming alcohol

  • avoid consuming caffeine

  • avoid things and people that stress you out

  • Restore the necessary amounts of vitamin D:

    • take vitamin D3 (10,000 to 20,000 IU daily)

    • take virgin cod liver oil

  • Restore the needed amounts of zinc:

    • consume beef liver

    • consume shellfish

    • take a zinc supplement

  • Restore the needed amounts of oxygen in your body:

    • exercise

    • take long walks outside

    • do hyperbaric oxygen therapy

Cause #2: High-carb diet

If you are on a high-carb diet this can result in brain starvation because blood sugar is not the best source of fuel for the healthy functioning of the brain, including the hippocampus. There is another type of fuel that your brain loves: ketones (a byproduct of your body burning its own fat). Additionally, intermittent fasting will trigger certain processes that will regenerate your hippocampus.


  • Avoid refined carbs and sugar

  • Avoid snacking

  • Do the Healthy Keto® diet

  • Do intermittent fasting

  • Take MCT oil (source of ketones)

Take an exogenous ketones supplement

Other cause:

  • Aging (Healthy Keto + intermittent fasting should reduce the aging effects)
