Perhaps not worry about calories at the start. Rather get your body roaring into action, and the ketosis will help you feel not hungry. Initially ketosis is fuelled by added fats. Eventually as your appetite drops, ketosis is fuelled by body fat. Body needs time to ramp up its ability to burn body fat. Can take a couple weeks for most.

Does that make sense??

Initially fat comes from the diet. That provides the satiety necessary to avoid hunger and continue the journey. Dr Atkins talked about 2000 calories a day, not 1400-1600. The initial weight loss is fluids as body rids itself of inflammation. Then weight loss slows as weight loss is from buring body fat.

Bottom line. Eat more fat for now.
