What are the characteristics of obesity injections? How do they differ from other procedures?

I have attempted dieting several times but have been unable to maintain a diet for long periods, so this time I plan to manage my condition through consultation with a professional. While doing so, I learned about weight loss injections, and I am curious about how they differ from the dieting methods I was previously familiar with. I looked up the characteristics of these injections and found many descriptions regarding appetite and satiety; I would like to know what aspects are checked most importantly during an actual consultation. Since receiving the injections does not mean I can completely abstain from dieting or exercise, I am also wondering how much I need to change my lifestyle habits alongside them. I would like to hear from those who have actually undergone management with these injections about the aspects they found most comfortable and, conversely, the parts they found inconvenient. I am looking for a method that allows for consistent management rather than expecting big changes in the short term. I am also wondering if keeping a record of my weight or meals is helpful information to prepare before the consultation. I would appreciate advice from those who have looked into this with similar concerns.
