Yup agree with all this... reduce carbs (gradually), increase protein and fats but keep an eye on saturated fats (keep them low). Then, if you can, increase your daily exercise. Gently at first.
You should find that your desire for carb heavy, sweet things will reduce with increased protein and fats and time. Yes, it takes a bit of time for your body and brain to accept and switch to a new regime.
But, a happier, healthier, fitter you awaits.
Me, HbA1c 150, weight 94 Kg. Every diabetic symptom possible. And I couldn't balace or walk or talk coherently. One week in hospital. Pretty serious stuff. But once I knew what I was up against (fellow hospital patient explained a few basics) (people on this site filled in many gaps in my understanding), I developed my own personal strategy of diet and exercise.
The result, within months I was in the no diabetic range, never out of range, healthier, happier, fitter. Weight down to 60Kg (was 55Kg, but that was a bit too far).
I astounded the medical 'professionals' but it is hard for them to argue against success and in the end they were quite supportive, but still expecting me to fail given time. Well, it's only been 2 years since diagnosis and since comming off all meds (they shoved me on them in hospital where I was very unwell - but that's another story) my Blood Glucose readings have been within the normal range.
It has been hard work, but so so rewarding. I get better, the health professionals do not, so all the rewards go to me.
Have I slipped up along the way? Yes and no. Occasionally, I have a treat of some sort, but adjust my diet and exercise that day to accommodate it. Seems to work and keeps me happy.
I test my blood every day several times a day just to make sure my strategy is helping and not going astray. In fact I test just about everything I can, out of sheer interest.
Planning meals turns out to be important but equally important is the ability to change meal plans easily. The only way to do this is to use one of the many calorie, carb counting Apps and keep a food diary. I keep mine on my laptop. It turns out to be very useful because we all live in our own personal routine and generally eat the same sort of things regularly, so creating a new days meals becomes easier and easier in time, using the data from the new low carb 'diet history'
And finally, do use this forum. There are some great people here, quite a range of experiences and advice. We all like to hear what works for others and we all like to help where we can when people struggle.
I discovered that my new diet (discovered over time) reset my palette and desires away from sweet things and I started to really taste food for the first time. Quite an exciting journey and very enjoyable too.
Many people initially think that diabetes is all about cutting out most foods and a boring diet, but that is completely wrong. It is about discovering food and discovering who you are in terms of how you react to and how you enjoy food. What a great new life !!!!
Good luck. Nah, luck has little to do with it. Aim straight, go for it, keep going.
