Reddit user loses 75 lbs using ChatGPT as his calorie tracker, gets flamed for it
zoo1514 · reddit · 2026-10-26
A Reddit user describes losing weight from 360 lbs to 285 lbs since June 25, 2025 by logging every weighed meal with ChatGPT, having it generate monthly charts of calorie intake vs. weight loss, and asking it to call him out when he exceeds his daily limit.
When he shared the method in weight-loss communities, he was heavily criticized for not using a dedicated diet or macros app. He argues ChatGPT only does the grunt work while his daily diligence makes the data useful, and says he now avoids mentioning he uses ChatGPT because of the hostility.
