I wish I could say that I had this planned, that I wanted to find out what I could get away with and still stay in ketosis. But that wouldn't be quite true.
I started by feeling I really deserved a sweet treat, so instead of ordering my regular decaf with half-and-half at the coffee shop I had a split-shot sugar free latte breve with caramel flavor. There was caffeine and sweetener in it, both things that I'm not sure my body does too well on.
Lunch was healthy and dinner was too. But after dinner I really wanted to try the low-carb cheesecake my daughter made. There was no sugar in it, but some Xylitol. After an hour I really felt like a 2nd piece and enjoyed it tremendously. So for better or for worse, I am going to find out by tomorrow morning how much effect all this had on my metabolism. The scales were at 132 lbs. this morning. I did not go over my allowed carb level by much, probably still under 40 grams of carbs for the day.
The reason for all those indulgences: mostly lack of planning to buy enough vegetables and make time for cooking combined with a longstanding habit of enjoying sweets. And sometimes I just don't want the work of cooking. The good news: I've really had enough of sweet things for a while now, and this is still far fewer carbs and sweet foods than I used to consume every single day of my life. If I feel I'm cheating when eating low-carb cheesecake and without eating any sugar other than what was in my blueberries I guess I'm still doing pretty well.
