Carrots have too many carbs for a low-carb diet (<=20g/day or 25g/day), but would work for a medium or moderate carb diet (<=50g/day or 100g/day).

Generally things like carrots, apples, or milk would be an occasional indulgence for this kind of diet. One serving is 10g+ of carbs (one apple, 1 cup of raw carrot, one glass of milk), which is over half the daily budget, so most would simply avoid them almost completely.

Another option is to do every-other-day fasting, which on eating days doubles your carb budget to still maintain a low average intake of carbs.

The typical ratio of macros in terms of calories is roughly 80% fats and 15-20% protein, with under 100 calories per day coming from carbs, so less than 5%.
