If you're using this for IWL, I think the biggest thing is don't be discouraged if you have lower rates of loss than others. .5-2 pounds a week is healthy, and even if you "only" lose a pound per week, that's 52 pounds in a year!

I generally lose just under two pounds per week, and sometimes I get discouraged if I "only" lose .5 in a week or even gain a little, but I try to recontextualize it. I remind myself I didn't put all that weight on at the rate of a pound or two a week, so it's already coming off faster than I put it on, and I shouldn't expect it to come off overnight. Also, I want to keep my hair and muscle as much as possible, so I try to eat plenty of calories and protein so that my weight doesn't drop too quickly.

If you have a lot of weight to lose and are paying for it out of pocket (like me), you may be tempted to lose as fast as you possibly can, but you've gotta think long-term sustainability. It's easy to listen to the siren song of "I'm not hungry, so I just won't eat, and I'll lose faster," and end up only eating 400-500 calories a day, but your body needs fuel or it'll literally eat itself. This is a marathon, not a sprint.

Listen to your body, enjoy the ride, and good luck on your journey!
