How do I not exceed my calorie intake but still get my carbs in? Breakfast used 4 carbs but 800 calories of my 1400 for the day.

I never worry about trying to get my carbs in.  I keep those as low as I possibly can, and always less than 20 net.  Then the calories fall where they fall, but typically I get around 1400 a day.  Typical day is 2 eggs or 2 slices of bacon and coffee with coconut milk, lunch is a salad with some kind of protein on it and olive oil/vinegar for dressing.  Dinner is a serving of protein and a serving of a green vegetable.  Snack is either a half ounce of almonds or a fat bomb, or a keto meal shake.  Hope this helps!
