For details I’m 23M, SW was at bare minimum 325 but probably more like 340-350 from pandemic weight and I now weight 207lbs and has only been 6 months into my weight loss. My worry is how quickly I’ve lost this weight and most of it has been in the past 2-3 months. On November 12th I weighed 238.8 and on December 12th I weighed 207.2 which is more then 31lbs in a 30 day span and in the previous 30 days I had lost 28.4lbs from October 12th-November 12th. I do strict keto and a 20:4/OMAD schedule eating 1500-1800 calories a day and haven’t really changed anything from when I first started to now other than a few different foods I eat now. Don’t really workout at a gym very often maybe once or twice a week for leg day but my job gives me all the workout it needs but have no idea how many calories I burn there but I do know it is a lot.
Regardless, you should probably get checked out by a doctor. That’s many times over the recommended rate for weight loss. My guess would be something medical and water retention related - although I would be concerned about losing a lot of lean body mass as well from dropping weight that fast. If you haven’t changed anything, it’s not like the body is going to suddenly start burning 3,000+ extra calories a day.
I’m starting again, gained it back through the years and two pregnancies. But back in 2011 I lost 65lbs in 3 months. Low carb and exercising about 45 minutes daily. I did lose a bunch of muscle, but nothing that hindered my life (I’ve always been weirdly strong). I was able to keep it off for 2yrs before my first pregnancy. Nothing came back abnormal. I do recommend seeing a doctor, but I’m just here to say it can and has happened without their being a medical emergency.
Hey are you sure you are remembering your weight values or dates correctly? I’m not saying you are lying or definitely don’t remember. I ask because at least two months ago you made a post stating you weighed 248lb instead of the higher 267.2lbs in this post. That would make your loss to this date only 41 lbs which while still high, is much more reasonable. However that doesn’t change the fact you lost 31lbs since Nov 12.
Also I notice you keep saying you get a lot of cardio/vurn calories from work. How long have you had that job? Are you calculating your total CICO from your job? If it’s a new intense job, the difference could be merely your heavy calorie cut combined with work calories burned.
