In general (please note this qualification) if someone is diabetic then potato is exceptionally bad for blood glucose levels and control, irrespective of how it is cooked. Although as with most things, moderation is fine.
See this is why advice from anecdotal nancies is totally useless. The average modern person will spends lots of time on useless trivia but avoid learning anything that could improve their lives. Carbs from vegetables like potatoes do not spike insulin like fad diet promoters and meat addicts like to portray. That stupid myth is ruining so many lives both animal and human.

Sugar, Coated with Myths
Sugar Does Not Cause Diabetes
After eating high-carbohydrate foods you might suspect that all that dietary sugar would cause the sugar in the blood to rise and this might lead to diabetes. That’s what many lay people believe. Even a few scientists have theorized that chronically elevated levels of sugar in the blood might wear out the insulin-producing cells of the pancreas and produce diabetes.11 Actually, this common thinking is incorrect—studies comparing sugar intake with risk of developing type-2 diabetes show people on high sugar diets are less likely to get diabetes.12 There is, however, a strong relationship between red meat consumption and diabetes.13
The lowest rates of diabetes in the world are found among populations that consume the most carbohydrate—for this reason type-2 diabetes is almost unknown in rural Asia, Africa, Mexico and Peru.14,15 However, when these people change to a diet rich in fats and low in carbohydrates they commonly become diabetic. Some of the highest rates of this disease (and associated obesity) are found in Hispanics, Native Americans, Polynesians, and Blacks who have recently adopted the American diet.16
The carbohydrates found in whole foods (starches, vegetables, and fruits) are much healthier to consume than refined sugars for a person wanting to prevent or cure type-2 diabetes for a variety of reasons—especially because of the adverse effects on weight gain and blood cholesterol and triglycerides of sugars compared to starches (more in next month’s newsletter). A high carbohydrate, vegan diet, has recently been shown to help diabetics stop medications and improve their overall health.20 (See my August 2006 newsletter)

Americans are getting fatter-and dying from it!
...A study published in the American Journal of Clinical Nutrition (vol. 66, p. 1264, 1997) by the department of biochemistry at the University of Sydney, Australia, found that beef raised insulin levels more than white pasta and that fish raised them more than whole-grain bread. When compared with rises in glucose levels, beef raised insulin levels 27 times higher than brown rice did!
Another important study showed that a high-complex-carbohydrate diet lowered insulin levels. In 1992, James Barnard, from the department of medicine at UCLA, published a study on the effects of such a diet, along with exercise, on hyperinsulinemia. After three weeks, adult-type diabetics and people identified with insulin resistance experienced a 30 percent reduction in insulin levels.
They also showed a significant reduction in triglycerides (26 percent), cholesterol (22 percent), and weight (body mass index 4 percent).
Furthermore, the state of insulin resistance that the authors of these diets claim causes obesity is actually caused by obesity. The fatter you become, the more insulin resistant you will become-for one important reason: Insulin resistance is an adaptation that helps people avoid becoming even fatter-by reducing the effectiveness of insulin so it becomes less efficient at fat storage. It's a protective mechanism!

Here is the study he did not cite that showed that when adjusted beef consumption raised insulin 27 times more than brown rice:Abstract: An insulin index of foods: the insulin demand generated by 1000-kJ portions of common foods.Full study (PDF)In another post you stated what you allegedly ate
, so I will list what is likely the majority macro-nutrient for each meal:
-- toast (soy/linseed)(mostly carbs)
-- coffee (no sugar, splash of milk)(probably most fat calories from the milk, and btw coffee with milk is what will really raise your blood sugar)
-- enough salad (no dressings) to feed 4 people for lunch with a handful of raw almonds(probably mostly carbs depending on the amount of almonds)
-- usually rice or noodles of some sort - although I only have 1/2 a cup of cooked rice - +lots more veges(mostly carbs)
-- probably under 400g of meat a week)(mostly fat +protein)
-- diet soda on occasion(mostly carbs from sugars)
So basically you are eating the majority of your calories from carbohydrate sources from what you self report(which is notoriously inaccurate) but saying you are on a "lowered carb diet". You may be eating less calories than before, or calorie restriction, but you are not on a lowered carb diet, because the majority of your calorie intake is carbs, thus you are actually self reporting you are on a high carb diet, which is actually the ideal macro-nutrient balance for humans. This is another reason why it is useless to take advice from anedoctal nancies, who anyway, cannot identify what a carb is, let alone be expected to be nutritionally literate.

PS. I too would suggest that Thrasymachus is banned from this thread. Frankly speaking I am unsure of his purpose on this site. I don't recall seeing a single positive, encouraging post of his. While this extreme negativity is often educational it is also largely unwelcome.
I am the only actual vegan posting on this thread, let alone the only one who is not the nutritional and dietary equivalent of the Flat Earth Society. There is no credentialed vegan author, clinician or even guru who is advocating low-carb, because it is useless and from the Dark Ages of nutrition. Instead you would rather have pseudo-science loving confusionists chiming in with anecdotes, but anyway giving every indication that not only are they ignorant of the dietary research literature but they are over-weight and likely suffering from other health issues(since contrary to the made up story earlier in this thread about people with excess weight on their waist being more physically fit, they are less so and more apt to develop almost every chronic disease and ailment).
