The Last Resort to Lower HbA1c Without Relying on Medication. 'Preemptive Chewing Doping' to Offset 'Insulin Delay'

When “HbA1c (the average of blood sugar levels over the past 1 to 2 months)” begins to exceed the reference value at a health checkup, many doctors will advise, “Please reduce carbohydrates and do aerobic exercise,” and if that is difficult, medication treatment (such as SGLT2 inhibitors or DPP-4 inhibitors) is started immediately.

However, why doesn’t your blood sugar level go down? It is because you are eating soft modern foods (eating fast) while leaving unaddressed the fatal weakness that Asians, including Japanese people, genetically have: a bug called “delayed insulin secretion (early phase secretion defect).”

No matter how hard you try to restrict carbohydrates, if your way of eating (interface) is wrong, even a small amount of carbohydrates will cause a violent blood sugar spike, and your blood vessels will gradually become battered. The strongest physical hack to “preemptively activate” your own internal system before taking medication is the strategy of “making the first bite super-hard texture (high chewing density).”

It is GLP-1 that Fills the “Delay” of Insulin

In healthy people, insulin is secreted instantly when food enters the stomach, suppressing the rise in blood sugar levels. However, in pre-diabetics (people with high HbA1c), this “early secretion” is extremely weak and slow, so for 30 minutes to 1 hour after a meal, they are exposed to a dangerous hyperglycemic state (spike) where they cannot process the glucose overflowing in the blood (impaired glucose tolerance mechanism related to E02).

It is a hormone called “GLP-1 (incretin)” secreted from the intestines that covers this delay and strongly boosts insulin secretion. Recently, it has also become famous as a “weight-loss drug (GLP-1 receptor agonist),” but humans originally possess a cheat command that allows them to secrete a massive amount of GLP-1 on their own through “powerful chewing stimulation (repetition of chewing movements)” at the early stage of a meal (pre-digestive phase satiety and incretin response in E05).

The Protocol of Betting Everything on the “First Bite”

There is only one rule to dramatically improve HbA1c. It is to stretch out the beginning of the meal (the critical 15 minutes before insulin stands up) to the limit with the number of physical chews.

1. Not “Veggie-First” But “Hard-First”

It is correct to eat salad first, but swallowing “soft potato salad” or “leafy greens covered in dressing” in a few seconds may act as a buffer for blood sugar levels, but you won’t earn any GLP-1 secretion (insulin boost).

• For the very first bite, absolutely place an ingredient that takes time to chew and crush: Unsalted almonds, raw carrot sticks, thick and hard dried squid or kelp, or hard-boiled brown rice.
• Intentionally continue to chew these “40 times per bite (until they are completely liquefied).” This “violent chewing movement in the first few minutes” becomes an intense “ready” signal to the brain and intestines, making the dormant pancreas mistakenly think, “A massive amount of food (sugar) is coming!”, accelerating the preparation of insulin.

2. Do Not Eat “Strong-Tasting Side Dishes” Alone (Preventing Washing Down)

The traditional Japanese set meal (rice, miso soup, and strong-tasting side dishes) tends to induce the worst behavior (E07) of “shoveling down white rice without chewing (washing down due to eating foods in a triangular cycle)” to neutralize the strong taste.

• Stop putting side dishes and rice in your mouth at the same time.
• First, thoroughly chew and crush the side dish (protein or vegetables) alone, and when the taste fades, chew the white rice alone. This “separation of chewing” prevents unconscious fast eating and evens out (flattens) the peak curve of postprandial hyperglycemia.

HbA1c is not a certificate of “how much sugar you consumed.” It is a cruel report card showing that “you slacked off on preparing for insulin acceptance (borrowing GLP-1 in advance by chewing) before bringing sugar into your body.” Before relying on medication, first reinstall from the physical system of “changing the first bite to a hard texture.”
