Prediabetes Can anyone help or advise?

Hi

Around a year ago i had an early morning blood test for an insurance policy i was thinking of taking out, i had been in the gym and showered just prior to the blood take by a nurse who came to my home. When the results came back i was horrified at a fasting reading of 7.2 with a refusal for the insurance and a recommendation to go to the doctors.

I bought a blood glucose meter, read everything i could and realise that my blood levels would be odd afer a hard hour in the gym, i went to the doctors and found my hba1c level was 46 which is in pre diabetic realms.

I decided to cut my carbs out, dont drink in the week and alter my exercise programme to HIIT training as well as weights and running, i monitored my bloods with the meter and all bar first thing in the morn when the reading hits 6-6.2 it is all ok, my last hba1c was 42 so although work to do, better.

My issue id i have always been a big guy, not fat but well muscled but i have lost 1.5 stones and still losing and it is making me miserable, i just dont seem to be able to eat the calories needed to keep to the weight i want also i just dont seem to be able to eat as much as i used to with the level of protein i consume.

Does anyone have any suggestions as i really dont want to go back eating carbs but dont know what else to do.

Thanks

Thanks - i have n the mornings a protein shake at 6.30am - 9.30 i have frozen fruit (defrosted) with full fat greek yogurt, lunch large piece of fetta cheese, chicken breast and some leaves or soup and low carb crackers with mackerel on the cracker (something like that) dinner it would vary from liver and cauliflower mash, a vegetarian meal of some sorts etc, chicken stir fry. No alcohol during the week, eat more freely at weekends but not mad with the carbs - never eat any cakes, sweets, desserts, biscuits or the like but no sweet tooth. I dont eat after 8pm and dont snack between meals but i find it hard to eat much more ... appetite has crashed.
