The loose guide is that you should aim to lose 10-15% of your desired weight loss in the induction stage (someone correct me if I'm wrong, it's been 3 years and I need to re-read the book!)

If thats the case, then yes, you're right on track! I work in lbs, so you were 155 lbs, you are now 151 lbs, so you've lost 4 lbs, which is great because you dont have much to lose at all. 4 lbs would be within the 10-15% mark!

Also, don't weigh yourself every day. Stick to one day a week. The reason for that is mainly because your weight can fluctuate greatly, even throughout one day! Choose one day to weigh in on, and weigh in at the same time each week. For me, it's Monday morning (after a trip to the bathroom!)
