You will hear this a hundred times, but yes, it's normal. No two people will have the same experience from surgery to weight loss to maintenance. There is almost no difference between 4 and a half weeks and 5 weeks, so I'd say you are in the ball park. Congrats on your 17 pound loss! You can look forward to more coming off in the future. You will eventually learn your patterns, which may steady and slow, stair step and quick. Good luck as you continue in your progress.
