Have used chatGPT for about a year to count my daily calorie in-take .
Since I eat out daily at fairly healthy places (Cava, Panera, chic fil a only grilled nuggets & fruit cups, Jersey Mikes number 7 mini, noodles & company, MOD pizza) GPT knows their menu & each items calories. Upon getting the food I just tell GPT what I'm about to eat each time and it counts & retains and calculates through the day.
In doing so as adult male (late 40s) 5'10 175 my body has gotten used to eating 1500 to 2k calories a day. Do weigh myself daily to ensure I'm not gaining as I do have a cheat day once a week.
I understand the sodium content is higher then if I cooked at home but I'm focused on maintaining a fit look & counting calories along with a few weekly gym visits I think keeps me as I seek.
