If your training hard and going low sodium, change that. Either dial back or dial up. You need sodium for sweating. As I understand it, a little high is far better than a little low. Second, you will stall here and there. Pushing harder won't necessarily make the weight come off. Your body has to adapt and it will hold water in the fat cells like a bookmark just in case it needs to go back. Once you've adapted to the new size, it will release that water and you'll get a big drop one day. You also have to see whether your losing fat or weight because their two completely different things. Weight loss can be from blood, water, muscle, fat, etc so its not ideal to see big numbers all the time. You have to watch the scale and the mirror. You want numbers going down, but you also want to see results in the mirror over time. Dial back on cheat meals. One a week or something.
Other random thoughts. Just adding more cardio or removing more food, or both together doesn't always force a change. You have to get a routine and follow it for weeks. Once you get things set, then change one or two variables for a couple weeks. Changing too much too often is just chasing your tail. Also, it says card, but I think you mean low carb. Cycle that. Don't just cut those out for long stretches. Moderation in everything is the key. Cut for a duration, but then reintroduce them to keep your body refueled.
Maybe the best thing is to just say tighten up your diet and get into a routine. This is like a science experiment so you need to establish a baseline and then go from there.
