What should I keep tracking after stopping?

Five things. Weight, daily, with a seven day rolling average. Protein, in grams per day, against a target you do not negotiate down on bad days. Body composition, ideally a DEXA scan every three to six months but a smart scale or BIA reading is better than nothing, so you can tell whether weight changes are coming from fat or lean mass. Fasting glucose and A1C, especially if you took the medication for type 2 diabetes or prediabetes, so you can see whether the metabolic gains are holding. And your habit checkboxes, the boring daily binaries for protein, training, sleep, and hydration. Phaze keeps each of these on one screen, so you do not have to stitch screenshots from five different apps to see the picture.
