LL, thank you. So interesting about the gut issue. I must 'explore' etc. I suppose (?) that a slower release (from lo GI carbs) helps to ease the impact of a 'sudden hit' into the bloodstream from high GI carbs?
TDM - ah, that makes sense. I've been googling questions like 'are tomatoes keto' (to find out which fruit and veg are lower-carb), and they give the answer in 'net carbs' (which does make sense, if it's a question of what percentage per weight of the food item is carbohydrate (starch plus sugars), which I did find helpful (Tomatoes surprised me, as they cam back low net carb, when I thought that because they are sweetish would be higher, but hopefully there is a lot of non-carb in their gross weight)
