Hello KESTREL 521, and welcome to the Forum
You say in your first post that you don't understand why you have to be on a low carbohydrate diet; I think a simple biology lesson will explain that
The simplest sugar you can get is glucose, and this can be joined up with other glucose molecules, and other sugars to form longer and longer chains to form more complex sugars, and eventually, if you join up a lot of them, it forms starch; and all these long & short chains of sugars are called carbohydrates
When you eat them they are broken down in the digestive system, back down to the glucose, which passes through the gut wall into the bloodstream
From there it travels around the body and passes into your own cells to be used to help you live
The hormone insulin is produced by the pancreas and this enables the glucose to pass from the blood across the cell wall, and into the cells
If you don't produce enough insulin this transfer cannot take place, and has three results -
You cannot use the carbohydrates you eat to produce energy, so you feel tired.
And as you cannot use new food the body starts to use up its reserves, so you lose weight
The unused glucose stays in the bloodstream, and it is this accumulation that causes the problems we call diabetes, such as feeling thirsty, damage to the eyes and nerves. It also cause changes to the acidity of the skin, and the accumulation of sugar around the genitals, in both men and women, often causing the fungal infection, thrush.
There are three ways to solve this problem -
Take in insulin artificially by injection
Take medication which tweaks the body to produce more of its own insulin, and to make that insulin more efficient
Reduce the amount of carbohydrate you consume, which will in turn reduce the amount of glucose in the bloodstream
Of these, it will help very much if you reduce your carbohydrate consumption ---- and it is important to understand that as all carbohydrates are made up of glucose, you must reduce your level of starchy things like breakfast cereals, bread, rice, pasta, potatoes, as well as the obviously sweet & sugary things like sweet, biscuits, cakes, & fizzy drinks
Many people take their diagnosis as the motivation to change the way they have been living, by cutting back very much on carbs, fatty food, junk food, processed food, especially meat products and convenience meals
Replace them with more veg, fish, especially oily fish, olive oil, a limited amount of fruit, and so on - in fact all the healthy stuff you hear about! As you do this, your consumption of sugar, salt, and bad fats will automatically reduce
Oh, and cut out smoking and a lot of booze, and do more exercise
If this all sounds like hard work and terrible news, well it need not be. You don't have to do it all overnight, and there are many Forum Members who have done that sort of thing, myself included. Quite soon it just becomes a new and different way of living
Nothing in the body happens in isolation, and these changes will help with weight, cholesterol level, blood pressure and similar problems, besides the diabetes
