My mind is really “foggy”

The feeling of a lethargic or “foggy” brain when you can’t put your thoughts together is often times due to a food allergy. Allergies can take up to 72 hours to affect you, so something you ate three days ago may be causing you not to have that sharp mind. Brain fog can also be due to a hormonal imbalance most commonly from the thyroid, but as well as from blood sugar imbalances. Some people also get what is referred to as ammonia toxicity. This occurs when your body is flooded with ammonia from protein being broken down in the body to be used as fuel. This often occurs with too much physical activity (people who run marathons or Ironman races), as well as those who use protein to make glucose (sugar) for energy – common in those who go too long without eating, especially over 4-5 hours. Ammonia toxicity can also be due to dysbiosis – bad bugs living in your digestive tract.
