I think the most important thing about your new eating plan is that it has to be enjoyable and sustainable as well as meeting your nutritional needs and blood glucose aspirations.
There's no ‘one size fits all’ approach, because we are all so different - and also because individuals react very differently to the same foods.
In general it is the total carbohydrates that you will need to keep an eye on, and while there are obvious things like cakes, biscuits, sweets and sugary drinks that you will want to cut out straight away, you might be surprised how much *all* carbohydrate affects your BG levels, including rice, pasta, potatoes, bread, pastry, grains, cereals and many fruits.
Many new members also find 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. It can be especially helpful to estimate the amount of total carbohydrate in the meals and snacks. This soinds like quite a lot of faff, but it will be an important learning opportunity to start understanding which foods are the main sources of carbs in your menu. It may even prompt some ideas as to which meals may need tackling first.
Sometimes that can involve a small tweak or a slight change of portions / proportions. Other times that can be a bit more of a complete rethink or a swap to lower carb alternatives with things like cauli ‘rice’ or celeriac mash.
There’s no set advice for the right amount of carbs per day really. Some can cope with more, others need to be a little more careful. 100-120g seems quite a common figure discussed by members who find a low carb strategy works for them.
Good luck and let us know how you get on
