I went on a 17-hour fasting yesterday for the first time, and walked about 20 minutes. For lunch (11 am) I had 2/3 cup tuna salad, about 5 pork rinds and 3 celery sticks with cream cheese. For snacks - a handful of peanuts/almonds For supper I had 1 and 1/2 pork sausages and mixed greens (leaf lettuces), 1 tbp peanutbutter, coffee For evening snack, 1/3 cup of home-made diabetic dessert (cream cheese, whipping cream, strawberries with Splenda) My glucose levels were all nicely down. But this morning, I weighed and I gained 1and 1/2 lbs compared to my weight the day before!!! Is this normal?
