At least once a week - Tuesdays - I have to work late, and I eat dinner at work. I have discovered that when I eat at home, a 1:10 insulin:carb ratio works. But when I eat at work, I need at least 1:8. This is so even though I always eat a lot less when I am eating at work. It makes zero sense to me. Do others experience this, and does anyone know why this happens?
