As well as greek yoghurt, double cream, flaked almonds and some kinf od berry (blueberries or raspberries, usually), I also do scrambled eggs with a dash of cream
I often have a veggie fry-up at weekends, but have recently discovered that the recipe or size of my favorite veggie sausage has changed and is now higher than it was, so I have reduced the number of sausages from 2 to 1
I have also discovered tofu based shakes which are higher protien and higher fat and quite low carb. My favorite is a Rose Elliott recipe for a lemon cheesecake shake, which also happens to be vegan. I plan to try a coffee frappucino type of shake tomorrow morning.
I also have nuts to hand in the event that I'm too disorganised to make something. Usualy macadamia nuts, almonds or walnuts, but often the Julian graves mixed nuts because they may be on special offer.
I used to eat porridge for breakfast before I started low carbing. I made my porridge with jumbo oats and oat bran, usually stirring in flaked or ground amonds and some raspberries. It didn't make me spike unacceptably high, but I had different sandards in those days (about 3 months ago) I think I may need to re-test.
Morning readings may be affected by liver dumps tho... or Dawn Phenomeon, mine often are

I tend to have my highest readings in the morning if I don't eat quickly enough.
