Video Summary
The liver produces glucose even without dietary sugar; some tissues require it.
Insulin is the 'off switch' for liver sugar production; long-term high insulin leads to insulin resistance.
The dawn phenomenon (morning spike) is driven by a cortisol surge and underlying liver insulin resistance.
To lower fasting glucose focus on lowering insulin resistance: low-carb eating, fewer snacks/longer meal intervals, and stress reduction.
Check fasting insulin (goal ~2–6 µIU/mL) and A1C to monitor progress; recovery may take weeks to months.
The liver can synthesize glucose from fats and proteins to supply tissues that need sugar; if the liver's output is uncontrolled due to insulin resistance or stress, blood glucose can remain high despite no dietary sugar.
A morning rise in fasting glucose caused by a cortisol surge (around 8 AM) that stimulates liver glucose release; it's often linked to long-standing hepatic insulin resistance.
When cells stop responding to insulin after years of high insulin exposure, the liver no longer receives the 'off' signal and continues to produce glucose, raising blood levels.
Check fasting insulin (ideal ~2–6 µIU/mL) alongside fasting glucose and A1C (three-month average) to detect insulin resistance and morning glucose issues.
Adopt a low-carb diet, stop frequent snacking (longer intervals or two meals/day), reduce stress (sleep, exercise, sun exposure), and increase activity after waking to use excess glucose.
Improvement can begin within weeks, but correcting long-standing insulin resistance may take several months of consistent dietary and lifestyle changes.
"Even if you don’t eat sugar, your liver will still produce it."
Many individuals may be perplexed by their high blood sugar levels despite not consuming sugar. Commonly, people believe that dietary sugar and starches are the only contributors to blood glucose levels, but this is only part of the equation.
The liver plays a crucial role as it functions as a sugar factory in the body. It has the ability to produce glucose even when dietary sources are absent. This means that essential tissues in the body, such as parts of the brain and kidneys, will rely on liver-produced sugar.
When someone follows a low-sugar or low-carb diet, their body tends to derive fuel from both dietary fat and stored body fat. The liver can then convert these fats and proteins into glucose.
"If there’s not enough insulin, your liver is going to be a sugar factory."
Insulin serves as a signal for the liver to regulate sugar production. A lack of adequate insulin can lead to an overproduction of glucose by the liver.
Unfortunately, prolonged high insulin levels can lead to insulin resistance, where cells become less responsive to insulin. This condition compels the liver to keep producing excessive glucose, assuming that it needs to compensate for low insulin levels.
"Insulin resistance causes the liver to think it needs to make more sugar because there’s no off switch."
Insulin resistance develops over many years of consuming high carbohydrate diets, affecting the liver's ability to recognize insulin and consequently leading to elevated glucose production.
Interestingly, people may not develop full-blown diabetes even after years of high sugar consumption because insulin helps keep blood glucose levels in check. However, elevated insulin levels remain undetected until insulin resistance becomes severe, leading to insufficient insulin to manage blood sugar effectively.
"In the morning, around 8:00, you have the biggest spike of cortisol."
The "dawn phenomenon" refers to the increase in blood sugar levels upon waking, even when no sugar has been ingested the previous day. This spike is largely due to elevated cortisol levels, which contribute to increased glucose output from the liver.
Insulin resistance, often unnoticed, may pave the way for significant morning blood sugar levels, caused by an inability to suppress liver glucose production.
"To correct insulin resistance, especially if your fasting insulin is above 12, it could take several months before things reset."
To effectively manage high blood sugar levels, it's recommended to adopt a low-carb diet, minimize snacking, and avoid consuming sugars and starches.
Intervals between meals should be longer, with a focus on having just two meals in a day, allowing the body sufficient time to stabilize blood sugar levels.
Reducing stress is another essential strategy, as stress can elevate cortisol levels, leading to increased sugar release. Regular exercise, good sleep, and adequate sun exposure can effectively lower stress.
Healing insulin resistance requires a consistent approach to diet and lifestyle changes, which may take weeks to months, but can ultimately lead to improved metabolic health.
"Understanding the hidden causes of high blood sugar can help in managing your overall health."
Maintaining balanced blood sugar levels is crucial for overall health, as high blood sugar can lead to various health issues, including insulin resistance and diabetes.
It is essential to recognize that blood sugar can remain elevated even in the absence of direct sugar consumption due to factors such as stress, hormonal changes, and underlying metabolic conditions.
Often, individuals may not realize the hidden causes of their elevated glucose levels, which can stem from stress-related cortisol spikes or other metabolic imbalances.
The concept of insulin resistance plays a significant role, as it can prevent the body from effectively utilizing insulin, resulting in sustained high blood sugar levels.
Recognizing these factors can empower individuals to take proactive steps toward better blood sugar management.
