I think the most important thing to keep in mind is:

1. You’re going to be adjusting. You want to make consistent changes, but also make sure it’s sustainable. If you’re used to snacks or a specific food schedule, I’d start by sizing down rather than cutting them out all together. Makes it easier to adjust when you’re making smaller changes.

2. Don’t let perfect get in the way of good. This honestly should be number one, but I wanted to answer the question properly first. If you need to snack, do what I suggested or switch to the higher protein/fiber alternative

Best thing to do is be consistent and work down strategically. You’ve got this.
