Not for everyone...
I am 6’ tall and, right now, about 262. I work out three times a week. I have a physically active job.
I have been on special diets where they provide 100% of the food. I was given 1200 calories a day. I lost 3 pounds in 3 months. It wasn’t until it was cut to 900 calories a day that we cranked up my weight loss to about a pound a week.
My doctors have FINALLY agreed that I have a metabolic issue. Unfortunately the test to nail down the issue costs over $10K and my insurance will not pay for it.
In the meantime they have me on Wegovy. It kills your appetite, virtually erasing all interest in food.
I would rather have them treating the underlying issue...in addition to the weight I have a low heart rate, low-ish blood pressure, and a low body temperature (about 96).

I’m not a doctor, but I don’t understand how it’s mathematically possible to sustain that weight on 1200 calories a day as the BMR on someone your size is well in excess of that if you even if you spent everyday in bed. 1200 down to 900 is 300 calories a day or 2800 calorie savings a week. A pound is about 3,500 calories, so the math almost checks out there. But, losing a pound a month on 1,200 calories at 262 pounds just doesn’t add up. The calories to maintain that kind of weight have to be coming from somewhere.
Check that 300x7 is 2100 cals which would be a little more than half a pound a week, all else being equal.
