Again, induction is a 14 day process. 1.2lbs every 5 days would average out to being just under 2lbs a week - and 2-3lbs a week is the recommended weight loss for EVERYONE.
Seriously- if that's all it takes to shake you, stay off the scale. You didn't put the weight on overnight, it's not going to come off that way either. You aren't far enough into this to have any real idea or clue so far as how your body is going to react and know what kind of losses you can expect.
If you haven't already, take your measurements. Put in your 14 days doing a clean induction (your menu looks great, btw), measure and weigh in and THEN figure out what the deal is. Doing so before then is just an exercise in frustration with too little information and therefore counter productive.
Besides, what are you going to get out of this or anything else if you quit when it gets difficult? You'll be in the same or similar boat without the knowledge and reassurance that you put in the work to do what needs to be done.
Hang in there.
You've barely just begun.
