Hi, VR6 Nut
As you already have kidney problems, going 'very low carb/high fat' on your diet would probably not be advisable, as it generally means increasing your protein intake a bit too.
You may need to reduce your carbohydrate intake, but you would probably be best going down the 'low GI/portion control' route, and trying a carbohydrate intake around 150g per day. Try to take in your carbs from above-ground veg and low GI fruits, having only small portions of (eg) multi-grain wholemeal bread, wholemeal pasta, brown rice and 1 or 2 small new potatoes.
Read around the forum about those two options. Phoenix (low GI) and Sid Bonkers (portion control) will probably have better advice than me, and will be able to give you some tips, so I hope they see this. You will lose weight if you get it right.
Meanwhile, have a discussion with your doctor about controlling your carbohydrate intake with your kidney condition. Ask for your strips back on prescription (say, for 3 months) to help you find out which carbs spike your BGs too much. It might work! :wink:
Best of luck!
