The forum is full of people who have managed to reduce or completely stop their medication.
You are not alone in thinking T2 is progressive and will require more/ stronger medication as time passes. Many Dr's and health care providers still have the same outdated view, but modern research and the members of this forum have proved that if you are willing to change what you eat, it is entirely possible to avoid medication and many of the complications that are associated with T2.
Understanding the problem is the key to success.
Our pancreas and insulin production is usually working as it should, but our insulin has become less effective. This means that when we eat carbs our insulin has trouble dealing with the resulting glucose, our blood sugar level remains higher than it should, so our poor pancreas is forced to release even more insulin.
Usually, before our levels are back to where they should be we get hungry and eat again, most of the energy (glucose) from our carby meal is still circulating in our blood.
High carb = more glucose, higher blood levels, more insulin, worsening insulin resistance, progressive T2, more meds and possible complications.
Low carb = less glucose, lower blood levels, less insulin, improving insulin resistance, less meds and complications, possible remission.
Of the three macronutrient - protein, fat and carbohydrates, protein and fat are essential, you will die without them.
We can live quite happily without carbohydrates, what little glucose our bodies need can be manufactured through a process called gluconeogenesis
If you base your meals around protein, healthy fats, above ground veg, salads and low carb fruit you will be giving yourself the best chance of a complication and med free future.
