Any diabetic can confirm for themselves my claim about the Dexcom G6's unacceptable persistent error states.
Simply compare the CGM with your glucometer (testing 8x per day, for example), and watch the CGM go wrong (and stay wrong) on day 5 or 6 of using the sensor.
I wish what you said was true. I would love to have a CGM that works better than a glucometer, but they don't exist yet. In particular, the Dexcom G6 is inaccurate in a harmful way.
Your fat sources should be nuts and olive oil and chia seed, with some cheese and egg.
Healthy food with lots of healthy fat.
The brain uses ketones as fuel, so you will find that hypoglycemia is easily handled. In ketosis, your brain will have plenty of fuel, even if your blood glucose drops too low.
The Dexcom G6 is the best CGM on the market, but its sensor filtering (Kalman or particle?) has smoothness and/or continuity priors that cause persistent inaccuracies.
I observe these persistent inaccurate states on the fifth or sixth day using a sensor. Calibration doesn't help. The reading goes wrong and stays wrong.
It probably happens to you, too, but anyone who doesn't test with a glucometer will likely not notice the failure. You will be harmed by these inaccuracies. Persistent inaccuracy is different than the Gaussian (normal) error of a glucometer, which is far more benign.
Also, CGMs are slow. The reading is based on interstitial fluid and lags direct blood glucose test by 15 minutes or more.
I have completely abandoned the Dexcom G6 and have gone back to 16x daily finger stick blood testing. I am also on a low-carb/high-fat diet, which makes it easy to maintain normal human blood glucose. My HbA1c has been 4.9 for a decade.
I was overjoyed to use the CGM at first, but it turned out to be a net loss. If you want to control your diabetes, use a glucometer and adhere to a strict low-carb/high-fat (ketogenic) diet.
