There are many factors that affect your rate of loss: age, gender, starting weight, genetics, etc. Some are slow losers others are fast losers to begin. The rate you lose doesn’t affect the amount of weight you will lose. There are slow losers who reach their goal & fast losers who don’t.
Don’t worry too much about your weight loss immediately post surgery. You have swelling, possibly still retaining fluids, your body is under stress, etc. Some surgeons even advise not to weigh yourself for a couple of weeks after surgery because of this.
There are a couple of things you can rely upon. We all lose at our own rate & your rate of loss will slow as you get closer to goal.
Every pound you lose is a win. Congrats on your surgery.
