There are a couple of general adages to go by:
1: The more you have to lose the more you’ll lose in the beginning.
2: You will lose at the rate that’s best for you. Some people lose slowly, others more quickly but both are right. It’s not a race or a competition.
3: The closer you are to goal, the more slowly you’ll lose.
Simple things we say but all are true.
Honestly, the reason why this has been the most successful weight loss experience I’ve ever had (& I’ve done a lot: diets, clubs, medications, ...) is that I’ve actually stuck to the changes I made to my diet to lose the weight. In the past, I’d reach my goal & then I’d slowly but surely go back to how I used to eat & I’d start to gain again sometimes within a week or so. I’ve never stuck to it as I am now. That has been the difference for me.
Good luck.
