Our body can’t completely assimilate, digest and burn calories when you are under the physiological stress response.
The blood pressure rises, the heart rate increases, and the blood is shunted away from the midsection. The blood goes to the legs, arms and head for quick fleeing, fighting, and thinking. Stress is any imagined and real threat and the response of the body to it.
The stress response causes:
- Decreased oxygenation to the gut
- Decreased nutrient absorption
- Decreased enzymatic output in the guy, as much as 20,000 fold
- As much as four times less blood flow to the digestive system
Many nutrients are excreted during the stress, including:
- Water-soluble vitamins
Under the stress response, the body increases the production of insulin and cortisol. Excess levels of cortisol cause weight gain around the midsection. The calcium excretion can increase as much as 60 – 75 mg within an hour of getting stressed.
In the following video you can see the presentation of the Mercola.com founder and natural health physician Dr. Joseph Mercola and Marc David talk about the important rules the stress plays in the digestion.
