OK, I'm not all that familiar with the SBD, though I do know it's in the low-carb category and I am a big Atkins diet and low-carbing advocate. When did you start this plan? And are you still in phase I?
On Atkins, there is a similar phase (to phase I)...called "induction"......and it takes about 2-3 days to burn up your glycogen stores, before your body starts to burn your stored fat. And after a while....even your normal hunger isn't all that strong...due to being in some level of ketosis (not to be confused with diabetic ketoacidosis).
For most of us on the Atkins forum.....it was somewhere in the neighborhood of 1 week of being quite hungry.......and then hunger significantly decreased and energy increased. In fact, I remained in induction for the entire 8 months and only added a few items when I reached goal and was in the maintenance phase. I am impatient (generally, when you go to higher phases, your weight loss slows down), but the main reason I did it was that it was the WOE/phase/level that caused all my ravenous hunger, cravings and binging behavior to practically disappear. And those things had been making me very unhappy and sabotaging weight loss.
I would have to study the details of the SBD to try to trouble-shoot for you....or at least, try to trouble shoot the cause of the excessive hunger. Could be not enough calories, not enough fat or not enough protein or any combination of them.

PS...I am still in maintenance...for almost a year now. The one meal you posted....steak, big salad, roasted/grilled veggies. Are you adding any fats? Butter or mayo? I HAD to add fat in order to control hunger and in order to lose weight (stay in ketosis)
