The Magic of Turning Meals into 'Aerobic Exercise'. The Mechanism Where Just Chewing 30 Seconds per Bite Explosively Increases Postprandial Calorie Burn (DIT) and Visceral Blood Flow

The equation “Eating = Getting Fat” is spoken of as an absolute truth in the world of calorie counting. Because of this, many dieters desperately reduce their food intake and force themselves through the ascetic practice of sweating on a treadmill at the gym afterwards.

However, when you deeply understand the structure of the human body’s energy (basal metabolism), you realize that this approach is highly inefficient. Actually, there is a giant furnace (boiler) that accounts for about 10% of the energy we consume in a day. That is “Diet-Induced Thermogenesis (DIT).”

This heat energy generated in the process of digesting and absorbing the food eaten is the ultimate cheat of “burning calories just by sitting and eating.” And the only password to fully turn ON this DIT switch is the “extension of chewing count and time.”

DIT is Not the “Movement of the Stomach and Intestines” but the “Flame of the Sympathetic Nervous System”

For many years, it was believed that “DIT is frictional heat (energy) created by the digestive organs working hard.” If that were true, whether you drank liquid food or chewed solid food well, as long as the calories transported to the stomach and intestines were the same, the DIT should be the same.

However, recent physiological research (biological experiments related to E03) has overturned this established theory. As a result of comparing a “group that ate curry (liquid food) fast in 5 minutes” and a “group that slowly chewed Blockmate (solid food) taking 30 seconds per bite (about 40-50 chews),” despite the calories consumed being exactly the same, the latter (the group that chewed well) had explosively high DIT (postprandial energy expenditure), and it continued for several hours after the meal.

1. Excitation of “Histamine Nerves” via the Chewing Circuit: Long before the stomach and intestines start working, the moment the brain receives the vibration (input from the trigeminal nerve) of crushing hard things like “crunch, crunch” in the mouth, it releases a neurotransmitter called “histamine” from the tuberomammillary nucleus. This pushes widespread switches of the sympathetic nervous system and shifts fat burning (heat generation) in the internal organs and brown fat cells from idling to “full throttle.”
2. The Phenomenon of “Massive Blood Flow” in the Celiac Artery: As the number of chews increases, due to powerful signals from the sympathetic nervous system, the blood flow in the “celiac artery,” the main pipe supplying blood to the stomach and intestines, dramatically increases. A “bombardment of oxygen and nutrients” to the digestive organs begins, the stomach and intestines start operating at abnormal efficiency, and generate massive amounts of heat (DIT) (digestive phase activation in E05).

Burn Calories While Sitting with Just a “30 Seconds per Bite” Protocol

There is no need for strict dietary restrictions or forcefully going for a run after a meal. Redesign the “eating action itself as an aerobic exercise interval.”

• Setting a Rule Not of “Chews” but “Do Not Swallow Until 30 Seconds Pass”: Counting the number of chews (30 times) is painful. Instead, introduce a rule where “once you put a bite of food in your mouth, you just keep repeatedly moving your jaw until 30 seconds pass on your smartphone’s stopwatch (or counting in your head).”
• Physical Stalling via Texture (Hardness): It is impossible to keep just udon or white rice in your mouth for 30 seconds (it melts and disappears immediately). Inevitably, you will start ordering ingredients with enough “physical endurance time (hard texture)” to keep crushing for 30 seconds, such as “unsalted roasted almonds,” “thick steak meat,” and “large-cut root vegetables.”

The flame of DIT will absolutely not ignite with fast eating. The seemingly inefficient act of “prolonging the eating task” is precisely the strongest hack that powerfully stimulates the sympathetic nervous system and drastically transforms your meal itself into a fat-burning program (workout).
