Congratulations on your weight loss, @maya54!
I lost 30 pounds after quitting my job in September 2019. My blood pressure was too high (part of what led me to quit the job). I started by cutting way back on processed foods, sugar and salt. I had already been working out a half hour a day, but I started walking, as well. I worked up to an hour walk daily. The lack of stress was probably the key, though. I have had no problem keeping it off, although every so often I need to refocus on my health goals (when I begin to snack without thinking).
