After 9 years with the band, I have a great eating routine.
Breakfast: Protein shake of some sort - usually a fortified slim fast. I sometimes have 4 oz of Total cereal, but the day always goes better for me with the band when I have liquid for breakfast.
*Snack: 100 Calorie Iced Coffee; or yogurt
Lunch: "lunch To Go" Tuna packs, if I eat at my desk. If I go out, I usually choose a cup of soup or one piece of fish - no sides.
*Snack: 3 or 4 oz of Almonds or Cashews; or yogurt; or sugar free pudding; or even another Slim Fast if I am really hungry.
Dinner: dinner is a little tricky. I usually have 3 to 4 oz of whatever I cook for my husband. He's a meat, potatoes and one green vegetable guy. I have a spinach soup that I make weekly and keep on hand to eat when he is having something that I can't do at all - like a big greasy hamburger.
*Snacks are important otherwise I am super hungry and eat meals too fast and they don't stay down.
After dinner, I try to stick to milk or Water. Eating too late in the evening gives me acid reflux.
I know you asked about a normal eating day, but for me Holidays are not even a challenge anymore.
I just ask myself if I want to feed my muscles or my fat cells and that helps me make good choices - most of the time.
Hope this helps!
