@Nelly122 ,
I would just like to say that I agree with all the advice. This is a great supportive, informative place.
1. A Blood Glucose meter is essential - don't let your GP put you off them! I too use a Tee2+ , but some others use the SD CodeFree (from Amazon) which also has cheap test strips. You will get through more test strips than you could ever imagine because at first you need to check before , then 2hrs after every meal until you know what you can eat and what you can't.
2. Diet ,most of us call it lifestyle since you need to plan to be on it for the rest of your long and healthy life, gives much quicker results than exercise. You can't outrun a bad diet!
3. Some people go for a crash diet, or just try to reduce Carbs.It is important to reduce all carbs - even those that your Doctor says are 'healthy' - they all turn into sugar (glucose) after digestion. I feel that is often too difficult to maintain. I went for Low Carb High Fat (even though I have/had Coronary Artery Disease- a 3x Bypass).
The High Fat part of it enables you not to feel hungry. I have only felt hungry once since I started LCHF back in May 2019 - and that was after a 23hr fast as part of an experiment. Almost everything that conventional mainstream medicine has told you about Carbs and Fats is completely wrong, as you will discover for yourself.
