Hi
@Cocosilk,
Spiking on carbs while eating low carb is a well-known phenomenon, even for non-diabetics. This is due to a combination of adaptive glucose sparing (also known as physiological insulin resistance) and the last-meal effect.
Adaptive glucose sparing refers to the body preserving glucose for essential processes, such as creating red blood cells, but using ketones/fat for those that can use both fuels, such as brain and muscles.
The last-meal effect refers to the insulin release in your pancreas, which is determined by how much was needed for the last meal. So, as you increase the carbs you eat, your pancreas should rev up your insulin production.
So, personally I don't believe that spiking on carbs is anything to worry about when being low carb.
In the end, you have to make the decision as to how you want to eat. You might do well on either type of diet and it might come down to which way of eating you feel is easier to maintain for you.
