Sorry to hear you've been told you are at risk of developing diabetes. It must be extra stress you could really do without in the midst of your exam preparations!
When it comes to trying to find a new way of eating, many members have found it can be really helpful to keep a food diary for a week or two. Be brutally honest! Note down everything you eat and drink, along with a reasonable estimate of the total carbohydrate content (not just 'of which sugars') in your meals and snacks - it doesn’t have to be gram-perfect, the nearest 5-10g is fine. This will give you an understanding of your 'baseline'.
It might sound like a bit of a faff, and will involve weighing portions, squinting at the fine print on packaging, and possibly looking up things on the internet, but it will give you a really good idea of which foods are the main sources of carbs in your menu. Once you can see which meals or snacks are your ‘big hitters’, and where carbs might be unexpectedly lurking.
You can then use your diary to look for likely candidates for swaps, portion reductions, or using lower carb alternatives (eg celeriac or swede mash, or cauli ‘rice’).
Hopefully you'll be able to make some fairly modest and sustainable changes to your menu which will help your metabolism cope better with your meals and snacks and begin to reduce your BG peaks. This should have a positive impact on your levels of energy, and ability to concentrate. Often you don’t realise how weary, worn down and lethargic you have been feeling. Erratic and elevated blood glucose levels can be exhausting and are linked with low mood, but this may have come on quite gradually. Making a few positive changes can give you more energy, a clearer mind, and a brighter outlook.
Moderate and sustainable tweaks to your current menu seems a better way forward than "all about these crazy diets"
