Congrats on your loss so far! That is fantastic!
I hate having a goal weight by a certain date. I say that because if you are 201 by that date you feel as though you have failed, when in fact you haven't. You'd have lost 37 pounds! Sometimes our bodies don't let go of weight at a predictable rate. You can be doing everything right and you can still show a gain on the scale. The scale is not always a measure of our success.
You are wanting to lose a little over 3 lbs. per week until the end of July. Bandsters can expect 1-2 pounds per week. Sometimes more. As we get closer to goal, it tends to get harder to lose. Mainly because it is harder to create the caloric deficit needed to lose the weight. Can a person consistently lose a little over 3 lbs per week for 3 months? Yes. Will it be easy to do? No. I think it will be a big challenge.
Stick with your eating/exercise plan. With good habits the weight will come off. Don't give up on yourself! July 28 is my wedding anniversary, I think it is a great date!
