Daily Life and Compromising

So I tried to eat some carbs again and started with a half cup of black beans. Well seems after eating just fats, protein and very small amounts of carbs from vegetables my body does not know what to do with carbs. I lost 3lbs of weight from waking up on a empty stomach and eating them with my 8 egg omelette, then eating a chopped salad with eggs, hemp seeds, almonds in it for lunch then weighed in at my afternoon snack time weighing 4lbs less then I would normally at that time and 3 lbs less then when I woke up.......ok so much for that idea.
