The viscous circle of glucose derived from carbs, sugars, high glucose, high insulin production, higher insulin resistance, and even higher circulating insulin that is so bad for us (hyperinsulinaemia), symptoms, more carbs and so on for years will progress from, prediabetes, weight gain, more symptoms! More carbs, less initial insulin response, more Hyperglycaemia, more insulin resistance and the viscous circle continues.
Glicizide and gliptins work to stimulate the initial insulin response, because of the insulin resistance, so that the actual spike is lower than usual and keeps the blood sugar levels lower after food. This helps management of blood sugar levels, and helps with overall capacity to lower blood sugar levels.
But as we all know, a reduction in carbs at the prediabetic stage will prevent going T2.
Even those who are T2, will have better control with LCHF!
Hyperinsulinaemia, and insulin resistance is one of the major causes of diabetes!
I would have not had to go through all my battles of diagnosis, if my surgery tested my insulin levels early this century and possibly saved the NHS a lot of time and money!
