hi, my advise to you is to get your gp putting you on diabetes education course. this will give you a clear information on diabetic, what you can eat & whats good for you. its the only way to fully understand, get the grip of it & live a normal life again.
like you, i was concerned & confused but my gp had asked me if im interested on going to the course. it was the best decision ive ever made, its a 3 days courses but well worth it. id highly recommended! by the end of the course you wish you knew about the course when you were prediabetes. you could easily reverse back by knowing what to eat with healthy diet.
to put your mind at rest, you can eat pretty much everything but with the right portions & how many calories intake per day. from the course you will learn all that.
with that, all youll need to do is to make sure that whatever you eat, you dont exceed the daily recommendations as below:
Calories: 2000kcal
Total fat: 70g
Saturates: 20g
Total Carbs: 260g
Sugars: 90g
Protein: 50g
Salt: 6g
this is your allowances to eat per day. to understand fully in depth, i highly recommend you to get your gp putting you on dietitian course or youd never be overcome your worries. good luck!
