It's ok to eat the same thing everyday I think. Don't feel pressured for variety. If you eat broccoli and chicken, or broccoli and steak almost every meal and some berries for dessert, the science shows this is very unlikely to raise your blood sugars much. Eat eggs for breakfast, non-starchy vegetables, and if you need to snack, snack on nuts and seeds. Drink only water as well, or tea or coffee but water is best. Absolutely no sugary drinks (pop and juice), nothing packaged, no breads, cereals or grains as well if you can manage that. This should keep blood sugars down from what I understand.
