Is 1700-1800 calories a good amount to lose weight?

Hello,

Im a 32 m 5 ft 6 190 pounds and was wondering is 1700-1800 is a good amount to lose weight? I have lost 80 pounds before on keto and went to 215 down to 135 a while ago but wasnt tracking calories on it. I used this calculator aextreme weight loss would be 1400 and mild 1 lb a week would be up to 1900.

Im working on walking 30 mins everyday, logging my calories, and doing a 3 day gym split.

Let me know your t houghts. Im wondering if i should aim for 1500-1600 instead. Im also focusing on a lot of protein and not as much processed food.
