B.O.L.T. - BRAIN-OPTIMAL LOOP TUNING
Understanding Brainwave Frequencies
BETA brainwave is usually the predominant frequency when under stress; focusing on thoughts rather than directing the mind to go into ALPHA state, a calming effect you can control through biofeedback training.
BEFORE PURSUING ANY BIOFEEDBACK TRAINING, TALK TO YOUR PROVIDER AND/OR PHYSICIAN.
The Shift from Brain Chaos
To reduce stress, control the effects on the body, the brain must shift from the predominant beta brain wave to alpha brainwave.
Brain Shifting
While the brain can generate alpha waves independently, it rarely transitions out of a stressed beta state until the heart and gut signal that danger has passed. This is because roughly 80% to 90% of vagus nerve fibers are afferent, transmitting sensory data upward from the organs to the cranial brain. Consequently, sustainable alpha-wave relaxation is unlocked when rhythmic breathing shifts the heart into "coherence"...a smooth, sine-wave pattern. This process works in tandem with the Enteric Nervous System (the gut), which relies on its own independent pacemaker cells to generate slow, rhythmic electrical waves that safely manage digestion.
Cortisol
Cortisol spikes within minutes of an acute physical or psychological stressor, rapidly triggering the body's fight-or-flight response. However, even after your brainwaves shift to a calm alpha frequency and you feel mentally serene, the physical body lags behind. Because circulating stress hormones must be actively broken down and metabolized, it typically takes 15 to 30 minutes following initial mental relaxation for systemic cortisol levels to significantly drop.
The HPA Axis & Belly Fat
The brain's Hypothalamic-Pituitary-Adrenal (HPA) axis prompts the adrenal glands to pump out excess cortisol. If the body remains on high alert, this chronic stress response disrupts sleep, weakens immunity, alters blood sugar, and rapidly drives the accumulation of dangerous deep abdominal fat.
Visceral vs. Subcutaneous Fat
- Visceral Fat: Sits deep behind the abdominal wall, wrapping tightly around internal organs like the liver, pancreas, and intestines. Because it resides beneath the muscle layer, it cannot be pinched with your fingers.
- Subcutaneous Fat: Sits directly under the skin and rests on top of the muscle layers. This is the superficial tissue that can easily be grabbed and pinched with your fingers.
Visceral Fat
DANGER! DANGER!
Visceral Fat is Highly Dangerous.
- Visceral Fat is often called "active fat" because it does not just sit there storing energy, it actively produces hormones and inflammatory chemicals that disrupt how your body functions. Because it is located deep inside your abdomen, it has direct access to your vital organs and the portal vein, which carries blood straight to your liver. Reduction of visceral fat is more than eating the right foods.
How Visceral Fat Harms the Body
- Triggers Chronic Inflammation: Visceral fat releases immune system chemicals called cytokines. These chemicals cause low-grade, constant inflammation that damages your blood vessels and can lead to heart disease.
- Causes Insulin Resistance: It floods the liver with free fatty acids, which interferes with your body's ability to process insulin. This causes blood sugar to rise, making it a primary driver of type 2 diabetes.
- Alters Cholesterol Levels: Excess visceral fat prompts your liver to produce more "bad" LDL cholesterol and triglycerides while lowering your "good" HDL cholesterol. This causes plaque to build up in your arteries.
- Raises Blood Pressure: The physical pressure of fat around your internal organs, combined with the chemical changes it causes, constricts blood vessels and forces your heart to work much harder.
Major Associated Health Risks
According to major medical institutions like Harvard Health and the Houston Methodist Hospital, carrying too much visceral fat directly increases your risk for:
- • Heart attacks and strokes
- • Type 2 diabetes
- • Certain cancers (such as colorectal and breast cancer)
- • Alzheimer's disease and dementia
- • Non-alcoholic fatty liver disease
Note: You can actually have a relatively normal weight or BMI but still carry dangerous levels of "hidden" visceral fat internally, which still carries these exact same risks.
