From comments at the source video.
1. Reverse diabetes in 8 weeks: 70% of patients came off medications by changing their grocery list.
2. Low-carb/ketogenic diet: Focus on whole foods, avoid grains, pasta, potatoes, sugar, and processed foods (“GPS”).
3. Insulin resistance is key: Type 2 diabetes is caused by insulin resistance, not lack of insulin.
4. Healthy fats: Use butter, lard, olive oil, avocado oil; avoid seed oils and processed fats.
5. Lifestyle essentials: Exercise, manage stress, get good sleep.
6. Practical tip: Meal plan, remove processed foods from your environment, track A1C and fasting insulin.

A few months ago I asked my doctor for a fasting insulin test and she said she has never heard of such a test. I found a place online where I got a prescription ordered so I got tested. I've watched a lot of videos on the keto/carnivore diets and the doctors always say to involve your doctor before making a medication change but that's not that easy, at least in the area I live. In fact, the doctor who had never heard of a fasting insulin test also laughed and referred to my gathering of information as "listening to Dr. YouTube". Oh, my A1c went from 7.4 to 5.5 by listening to Dr. YouTube

A fasting insulin test measures the level of insulin in the blood after a period of fasting, typically 8 to 12 hours, to assess pancreatic function, insulin production, and insulin sensitivity. This test is used to diagnose or monitor conditions such as type 1 and type 2 diabetes, insulin resistance, prediabetes, hypoglycemia, and insulinoma—a tumor of the pancreas that produces excess insulin. It is particularly valuable for identifying insulin resistance, which often precedes type 2 diabetes and is a key component of metabolic syndrome. The test may also be used to evaluate the effectiveness of treatment plans for diabetes or to monitor the success of pancreatic surgeries like islet cell transplantation.
The test is usually performed alongside other tests, such as blood glucose and glycated hemoglobin (HbA1c), to provide a comprehensive assessment of blood sugar control and insulin function. Elevated fasting insulin levels, especially when blood glucose is normal or slightly elevated, may indicate insulin resistance, while low insulin levels in the presence of high blood glucose may suggest insulin deficiency, as seen in type 1 diabetes or pancreatitis. In cases of suspected insulinoma, high insulin levels during fasting, accompanied by low blood glucose (<40 mg/dL) and elevated proinsulin and C-peptide levels, are indicative of the condition.
Fasting is required for the test, during which only water is permitted; no food or other beverages should be consumed for at least 8 hours before the blood draw. Some sources recommend fasting for up to 12 hours, and longer fasting periods are considered acceptable. The blood sample is typically collected via a needle prick from a vein in the arm, and results are usually available within the same day. The normal fasting insulin range is generally considered to be less than 25 mIU/L, though target ranges may vary based on individual factors such as weight, age, and medical history.
The test is also useful in assessing insulin sensitivity using indices like QUICKI, which combines fasting insulin and glucose levels to provide a reliable estimate of insulin sensitivity. This makes it a valuable tool in both clinical and research settings for evaluating metabolic health and guiding preventive or therapeutic interventions.
