“Carbs are needed”
Seems right.
Of course, the question is, in what quantity, when, how often, etc.
One suspects the true carbohydrate requirements are a small fraction of what average Americans consume.
Green vegetables, avoid the starches. You will get just enough carbs to balance, and none left over. Avocado, brussel sprouts, broccoli, salads, olive oil and balsamic vinegar as dressing.
