Symptoms, conditions and causes

What are the causes for low energy?

Having low energy can be caused by many things. The causes below have simple remedies that will reduce the fatigue. Normally you should have a good energy level without it crashing throughout the day.

Cause #1: Potassium deficiency

Potassium is a very important electrolyte (electrically charged mineral) for your body and its energy levels. You need 4,700 mg of potassium daily to support your body’s energy metabolism. If you are deficient in potassium, it can definitely cause low energy. You can mainly get potassium from raw vegetables.


  • Consume more vegetables (7 to 10 cups a day)

  • Get an electrolytes supplement with a lot of potassium

  • Avoid refined carbs and sugar (they deplete you of potassium)

  • Improve your absorption of potassium by taking the following:

    • apple cider vinegar (1 to 2 teaspoons stirred into about a cup of water)

    • betaine hydrochloride

Cause #2: High insulin

Insulin is a hormone that lowers the blood sugar after it spikes and also stores it as fat in your body. If you consume a lot of sugar and refined carbs this can result in insulin lowering your blood sugar below its normal level. This will cause irritation, tiredness, fatigue, and low energy until you eat sugar and carbs again. Additionally, over time it will become hard for your cells
to get enough potassium, because high amounts of insulin over a long time period reduce the ability of your cells to absorb potassium.


  • Avoid refined carbs and sugar

  • Avoid snacking

  • Do the Healthy Keto® diet

  • Do an intermittent fasting plan

Cause #3: Insufficient sleep

Sleep allows your body to recharge and be ready for the next day, energy-wise. If you are not sleeping well or you sleep but don’t rest throughout the night, this can cause problems with low energy the next day.


  • Take vitamin B1:

• nutritional yeast

• benfotiamine

  • If you exercise too intensively, reduce the intensity

  • Do long walks outside (45 minutes at least)

  • Before going to bed, unplug all the electronic devices from the outlets in your bedroom

  • Avoid blue lights (computer screens, phones) before going to bed

  • Avoid things/people that stress you out

  • Turn off all the lights in the bedroom when you go to sleep

Cause #4: Energy drinks

Energy drinks can be the cause of low energy, because they contain a lot of sugar as well
as caffeine (stimulant). Caffeine will give you a synthetic sense of energy and eventually (if
you consume it regularly and often) will wear out your adrenals (stress-regulating glands). Consuming energy drinks will give you a sense of energy for some time, but will result in a feeling of fatigue soon after. This tends to make you want to drink more energy drinks.


  • Avoid energy drinks that have sugar and caffeine

  • Instead, take more electrolytes

  • Consume nutritional yeast

  • To increase energy take MCT oil

  • To increase energy take exogenous ketones

  • Consume moderate amounts of protein

Cause #5: Not enough phytonutrients

Your body has certain components in the cells called mitochondria that can be considered as small energy factories. Your mitochondria are under constant assault from smoking, pollution and chemicals, along with high sugar, insulin and other factors. There are certain foods from plants that are called phytonutrients, as well as certain nutrients, that prevent the damage. The same phytonutrients also repair your mitochondria.


  • Consume cruciferous vegetables

  • Make a concentrated shake of green vegetables and consume it once a day

  • Do the Healthy Keto® diet

  • Do an intermittent fasting plan

Other causes:

  • Low testosterone

  • Low thyroid

  • Low iron

  • Low vitamin B12

  • Low vitamin D

  • Viruses (like Epstein-Barr virus)

  • GMO foods

  • Smoking

  • Too-heavy exercise

  • Chemicals/toxins

  • Adapting to the ketogenic diet

  • Phosphorus deficiency
