No Sue it doesn't - not when you are in Ketosis - when your body is using fat for fuel. Fat does not affect insulin levels so it fluctuates very little. The only carbs I eat is a portion or two of non-starchy veg with my main meal, and whatever is in the meat, fish, poultry or eggs. Some eat cheese, but the only dairy I have is butter, which is manly fat. Milk is too high in carbs (and makes me constipated!
).
Carbs drive hypos. People end up in a vicious cycle of being totally reliant on the carbs. Their blood sugar ends up bouncing from one carb 'hit' to the next. The more carb they eat in any one go, the higher the insulin and the lower the crash. I spent years before the Diabetes struggling with hypos. Even back then I had impaired carb metabolism, but it was driven by the carbs - the processed carbs and sugars. About 25 years ago a wise Naturopath advised me to eat low-carb. When I did, I was fit and healthy, lost weight easily and didn't have hypos! I knew it. But then those insidious carbs would creep back in and off I'd go again.
The difference now is that I understand what it does to me. I can see through it and i know the damage it is doing to everyone - not just Diabetics. I don't want to be sick any more - and the only way I can recover, is to dump the foods that were driving the disease. You don't suggest that an alcoholic drinks plenty of alcohol, so why tell Diabetics - who have impaired carb metabolism - to eat plenty of starchy carb!!!
There are quite a lot of athletes who low, or even 'zero' carb (just Google Charles Washington, or 'zero carb' for instance). They run perfectly well on low-carb and unlike carb-fuelled athletes, they never hit 'the wall' which is the point at which the body runs out of glucose and has to change over to fat-burning.
I just cannot see what all the constant haranguing is over the low-carb ethic! This is the way our ancestors ate for thousands of years! Not until the advent of agriculture and the problems that came with it have we been eating grains. Before that, the hunter-gatherers lived perfectly well on meat, fish, eggs and fat. They would eat wild vegetables and some fruit foraged from the hedgerows or plains, nuts if they could find them, milk (ALL raw and unpasteurised) if they had cattle, goats or sheep. They would make butter, yoghurt and cream.
Even today, some Maasai will consume up to a pound and a half of butter a day! That is where they get their energy. It is a very reliable and efficient source of energy, and unlike glucose, not only does it not run out, you don't need to keep topping it up either!
The point is, the human race is well able to adapt to a wide range of foods, from natural carbs to all meat and fat - the difference is that whether carbs-based or protein/fat based it HAS to be all natural and unprocessed and of high nutritional quality.
It is only when cultures and communities start to deviate from their traditional diet and add in our Western processed carb-based foods that they start to get our Western diseases. They have replaced their highly nutritional foods with stuff that takes away more than it gives.
This is SO logical. We are just so confused by the overwhelming barrage of obfuscation that spews out of the World of Science, that we cannot see the wood for the trees.
I did get a few hypos during the transition to fat burning as my body readjusted but it didn't last very long, and it didn't frighten me because I knew what was going on. Since the changeover I haven't had ONE hypo. As long as I keep my carb level under 20 grams I have no problem at all and even the odd foray over is fine too.
I am far from alone. There are an awful lot out there like me. We are reaping the benefits of going back to the way humans ate for thousands of years, not only controlling our diabetes, but healing our bodies into the bargain.
