Here are a few things that might help if you are stuck on a plateau. You may want to set one or two as baby step goals so that you can see if they are having an effect or not.

1) reduce your salt intake
2) try to reduce the amount of processed foods in general, they have loads of added salt and hidden sugars
3) eat probiotic yoghurts - they are good for millions of reasons and if you are lactose intolerant, they usually are fine anyway. Test with a couple of spoonfuls first
4) drink lots and lots and lots of water
5) drink green tea, they make them with mint, jasmine, ginger etc
6) look up specific yoga moves to increase metabolism
7) change your eating habits around I.e. Eat 3 balanced calorie amounts, or every 2 hours, or heavy breakfast, heavy lunch, light dinner
8) change your exercise routines, go for low impact, low calorie burn during longer workouts
9) sleep... Try to get your 8 hours a day so that your body can repair itself
10) make sure you get at least two rest days in your body needs time to repair
11) reduce the number of hours exercise to 3 per And then to top it off, I crashed and fell asleep before getting all my water in.
if you are on such a low calorie intake
12) make sure you get 1200 calories per day if you are not sedentary, your body won't let go of the weight if you are burning muscle and not fat
13) check your macros. You may be eating the right amount of calories but if your sugar and fat are continuously high, they may be impacted your weight loss, (though I have not looked up any information about that)

Good luck
