Yet another load of sciency nonsense.
If anybody wants to lower his blood glucose and avoid insuline peaks, all he has to do is to avoid carbs.
Still better, all he has to do is to do the opposite to what is recommanded by the nutrition “science”, such as this study.
Type 2 diabete can be in remission with a carb free (keto or carnivore) diet, sometimes in less than 1 month. This has been proven times and times again by the thousands of patients of clinicians like Drs Westman, Unwin, Paul Mason...
I unfortunately have T2. In my experience, the combination of mild exercise, low carb, AND low calorie intake effectively contribute to lower A1c levels.
The liver and muscles store glycogen which when needed is converted to glucose. But exercise can help to drain off excess storage levels. Excessive stored glycogen can take months to properly regulate. The stored glycogen also contributes to the Morning Phenomenon where glucose levels are high upon awakening as a consequence of glycogenic glucose injection — the body’s natural caffeine.
Also, I’m effectively on a keto diet, but I can easily gain weight. So here’s where the calorie intake matters.
