200g is not excessively low in my opinon. What are your goals? 3500 is probably not cutting, right? I suppose bulking or maintenance on that amount of carbs is ok for someone who is carb-sensitive and stores fat easily.
200 grams of carbs on a 3500 calorie diet isnt that big of a concern. I'm cutting on about a 3500 cal diet and aiming for in between 100-150 grams of carbs. Though I have found that 1 day a week I need to have a very high carb day. But also when I count my carbs I am not taking into account what I get from most of my veggies, so really my carbs are from my oatmeal in the morning and a little bit of rice or pasta at lunch. Hope that sort of answears your question and jsut wasnt pointless rambalings.
