If you are young and active, I would guess that adding some starchy veggies to that meal might help. Try some winter squash, yam, or the like with some butter and see how you feel...And I do think that at three weeks in, that your body would definitely still be adjusting, especially if you were eating SAD.
If you're hungry just eat. If weighing every gram work for you, do it. But I'd advise you stop that and just eat till you are not hungry anymore, just listen to your body. Unless you only weighed and measure this meal only to provide us more info in this post. And 8oz of steak with a couple pieces of bacon is really not that much food, especially if you're young and athletic.
Make sure you're getting to bed in time, sleeping 8-9 hours. Personally, my hunger gets all weird when I don't sleep enough.
