You need a balance of veg. If you needed to hit 180g of carbs to get things going, there's a chance you weren't eating enough leafy veg (low in carbs and high in cellulose and soluble fibers). Maybe not, but my guess is that you'd need at least an apple and 100g of cabbage/spinach/lettuce a day to keep well. That's loads of fiber right there, and can fit into LC, if you want to take that route. Unsure about VLC.
