Hi Jessy. Welcome to the forum. Fruit is not the best choice for breakfast, have you checked if it spikes your BG levels? You might be better with bacon, eggs, or high meat content sausage. You will only know by testing different options. Some people are OK with weetabix protein (with almond milk, sugar free obviously), or Burgen bread.
Oranges are also high carb, I make a dessert of sugar free jelly made with half water and half cream, it's really nice and low carb.
