i go through ups and downs but use an app on my phone to log calories, protein, fiber, and workouts. most days im sitting around an 800-1000 calorie deficit, and it takes roughly 7700 calories to burn a kilo of fat. also got a withings scale that roughly tracks muscle, fat, visceral stuff, mostly just watching the trend over time there. bottom line is glp1s quiet the noise and slow digestion down, making the calorie math easier, though the actual work still falls on you. apparently a few compounds further down the pipeline also raise resting heart rate, which is interesting, maybe worth watching for anyone with cardiac issues. anyway good luck and keep tracking those calories.
