Figure 1

An example of blood glucose values in one person before and after a reduction of carbohydrates and insulin. The arrow marks the change. There are 25 measurement over 6 days before the change and 39 measurements over 7 days after. Mean BG in the left side is 14.0 mmol/l (range: 5.9 to 23.1 mmol/l). Mean BG in the right side is 6.4 mmol/l (range: 4.0 to 9.5 mmol/l). It is evident that lowering of the mean blood glucose in the left side of the figure is impossible without hypoglycemia. Flattening out of the small spikes in the right side can be done safely.
