Great news. It doesn't happen over night. Slow and steady wins the race. I could live on fish and eggs but I certainly enjoy my poultry and lamb/beef. Maybe you could eat those when your sister isn't around? Batch cook and freeze when she's not there?
Yup, that's a nice slow bump. We're not just looking at specific numbers., though they of course are important but we also need to look at the rise and fall. The idea is to keep both of those as steady as we can.
As I said, mornings can be difficult for many of us. I just eat avocado as it has the least effect but I still rise regardless. Just less than if I ate carbs or protein. It's actually worse if I don't eat. Afternoon things calm down. Most of us are insulin resistant in the morning and as the day goes on we're more sensitive. That's why I save the bulk of my low carb diet for dinner.
You seem to headed in the right direction. Pat yourself on the back. Keep up the good work and your efforts will pay off
