What is the treatment cycle for the obesity injections?

I came across some information about obesity injections while researching how to properly start managing my weight, and I have some questions. Since I believe the frequency of hospital visits and consultations is just as important as the usage method, I would like to know what the actual management process is like. I am curious whether the injection schedule is fixed or if it varies depending on the type used and the individual's condition. I would also like to know if the procedure involves frequent check-ups initially and then increasing the intervals later. I am also wondering if there are cases where the injection schedule is arbitrarily changed if there is a period where weight loss is not progressing well. Rather than trying to lose weight as quickly as possible, I am considering a strategy of maintaining my weight while also changing my lifestyle habits. I am also curious if it is helpful to record my food intake and exercise levels while managing obesity injections. If anyone has actually received a consultation, I would appreciate it if you could share how often visits were spaced out at the beginning and what specific aspects were checked at the clinic; this would be very helpful for me in planning.
