This past spring, after 18 months of great success on the keto diet, I tested my fasting blood sugar on my home glucose monitor for the first time in many months. The result shocked me. I had purchased the device, which also tests ketones, when I was diagnosed with pre-diabetes in the fall of As I embarked on low-carb keto eating, I tested my blood regularly. Soon my fasting blood sugar was once again in the healthy range. I was in optimal ketosis day after day. Not only that, I lost 10 lbs 5 kg and felt fantastic — full of energy with no hunger or cravings. I put the meter away and got on with my happy, healthy keto life.
In their intervention, subjects consumed a LCKD diet with the goal of eating less than 20 grams of carbohydrates per day while reducing dosages of diabetes medication. The blogs we publish here cover a range of topics, including new and original approaches to diet and healthcare, analyses of the latest cutting-edge research, deep-dives into specific nutrients, botanicals, nutraceuticals and more, all fully referenced for those who want to dig deeper into the primary literature. A simple program that you can follow along with, learn about keto, and easily control your diabetes symptoms. The test should be repeated to confirm that the results are consistent or it should be used in conjunction with a fasting blood glucose or an oral glucose tolerance test to confirm the diabetes diagnosis. They randomly divided them in one of three equal-calorie diets for 8 weeks. Soon my fasting blood sugar was once again in the healthy range. On a low-carb diet the HbA1c will almost always be lower than the FBG suggests, showing that good glucose control, or type 2 diabetes, is not an issue for that individual.
The vast majority of people who adopt a low carb or ketogenic diet experience stunning improvements in blood glucose control and insulin levels. However, individual variability being what it is, a small percentage of patients see a rise in fasting blood glucose after some length of time on a very low carb diet. Considering that elevated fasting glucose is part of the diagnostic criteria for both type 2 diabetes T2D and metabolic syndrome, is this seemingly paradoxical rise a reason for concern? There are many reasons why FBG might be elevated, and many ways to assess metabolic health and glucoregulation beyond just this one measurement. The dawn phenomenon will be well known to any physician who treats patients with diabetes or insulin resistance IR. Blood glucose naturally rises in response to surges of cortisol and other energy-mobilizing hormones in the early hours of the morning. This happens in everyone, not just those with diabetes or IR, but for healthy people with good insulin sensitivity, by the time they wake up, glucose has come back to a normal level.
