Ok, according to the Atkins carb counter, the net carbs for 1oz of almonds: 2.6, 1oz of coconut: 2.3, 1oz of walnuts: 2.0. I did find an almost empty bag of chopped walnuts deep in the fridge, and 1oz = 1/4 cup, so that's quite a good portion. I think that's why I started using just a tablespoon of each. But even if you used an ounce of each, your still at about 7 net carbs(there's a lot of fiber going on here) before your sweetener and cream/milk. So again, the amount you have depends on the amount of carbs you're allowed at your current phase.
