Diabetes is the inability to properly process carbohydrates so the treatment should be to not have carbohydrates. The concern is not that carbohydrate-laden snacks will displace anything but that carbohydrate-laden anything will be eaten.
The Atkins low carb diet starts at 20 grams per day not the 120 grams suggested here. 120 grams is better than the 300 grams the average American eats but why stop there if your metabolism is already disordered? The advice to take that many carbs and spread them through the day to mitigate glucose spikes is like telling an alcoholic to spread out martinis through the day to mitigate being drunk.
There are plenty of free low carb/diabetic information sources on the net. A readily available blood glucose meter (often free) and plenty of test strips (shop around) tells you what your particular body does in response to the particular foods you eat.
Low carb diets can be rich and delicious. They are also significantly more expensive than diets made from cheap corn and wheat. The cost of health care is so extraordinarily out of whack that paying more upfront to never see your doctor or dietitian again is worth it.
