I know it's carbs, but whole meal doesn't cause spike as white. I lost so much weight so decided to have some carbs, and don't think I will be able to cope with having no carbs at all for the rest of my life. I only shop in Tesco or Sansburys. Nearest Lidl is at least 40 minutes drive.
Lidl protein rolls are awesome, but there are other options if you really can't go without bread. My local Sainsburys stock Hi-Lo bread which is only ~5g carbs per slice. Approx £1 per (small) loaf so not as cheap as some white breads but it does the job if I can't get to Lidl or they are sold out. Haven't seen it in Tesco, but my local Tesco does sell a Low GI bread from a local baker, but unfortunately still sends my BG too high.
