Yes, though, as Ivanrk pointed out, Stephan wrote about how insulin spikes are not a problem. It's the blood glucose spikes that are the problem, according to him and Chris Kresser. When I asked Chris about it some time ago, he set me straight on this (at least, I think he did
).
Insulin spikes OK:"...insulin spikes after meals temporarily decrease fat release from fat cells, but if you look at total 24 hour energy balance, insulin spikes, in conjunction with all the other hormones that are released in response to food ingestion, do not cause fat accumulation. This is exactly how you would expect the system to work if it were designed to constructively handle a wide variety of macronutrient ratios, which it is. Just as cholesterol did not evolve to give us heart attacks, insulin did not evolve to make us fat."

Some people would put that number closer to 140 mg/dL. …. Insulin doesn’t clear all the glucose as it enters the bloodstream, however. Some of it does accumulate, leading to a spike in blood glucose. This usually doesn’t exceed 160 mg/dL in a healthy person, and even if it approaches that level it’s only briefly.

http://chriskresser.com/the-healthy-skeptic-podcast-episode-9Interestingly, when people eat VLC chronically, they tend to become peripherally insulin resistant, so that eating more than a tiny amount of carbs spikes the BG and is allegedly damaging and thus, eating carbs from time to time may help avoid major BG spikes and the damage that reportedly comes with it, assuming this is all correct.
If BG spikes above 160 mg/dl are bad, as even many LCers apparently accept, then if you're VLC and choose to continue eating some carbs, or if you choose to eat particularly sugary foods like raw honey and sugary fruits, then it may be a good idea to check your postprandial BG measurements, to see how much your BG gets spiked at various quantities, to find the safe intake levels for you.
