The truth is, there isn't any for sure way to "jump-start" out of a stall. Most people will end up attributing their success to whatever they were doing when the stall did break. Usually what people recommend are correlations with very little evidence of causation. BUT, if something does seem to work for you, go for it, and if it keeps working for you, keep doing it.
Personally, I try to vary my food intake between lower and higher calories every now and then. I have absolutely no scientific evidence if this is effective, but anecdotally, I feel like I will often drop a few pounds after increasing my calories a little bit for a day and then reducing them again for a week or two. My longest stall in these first 5 months has been about 7 days, and some people wouldn't call that a stall at all. I am still expecting a much longer stall at some point in the near future.
I don't rely on exercise to break a stall. You'd have to workout intensely for more than an hour a day, every day to make more than a few pounds difference over the course of a year. Food choices are the main contributor to success in the long term, from the research I've read. What I believe is we must discover what foods work best for our bodies. Not everyone is going to have success following the "blanket" guidelines given to use by dieticians or nutritionists. If you are lucky, you'll get a dietician who believes in personalized nutrition, which is a relatively new concept that focuses on feeding your microbiome the foods they will help you metabolize the best. I believe microbiome health is the key, much more so that "low carb" or 'keto" or any other fad diet.
The DIETFITS study by Stanford showed that people eating both a low carb and low fat diet lost about the same amount of weight, but a portion of both groups also didn't lose weight or they gained weight, even though they were eating the same type and amounts of foods as the people who lost weight. This is most likely because of the differences in how their gut microbes processed the food. So, my point here is, you may experiment a little bit with what you are eating. We are trying to avoid glucose and insulin spikes which trigger fat storage, even on a low calorie diet, and some people can get those spikes with foods that don't trigger the same spike in other people.
From the recent big nutrition studies I've read, there are really only two sort of "universal" truths about eating: 1. Don't eat ultra-processed foods (especially things with 10 or more ingredients) and 2. Eat a wide diversity of plants, at least 20-30 a week to give a wide variety of fiber food to your microbiome. A "wide diversity" does not mean you have to eat a large volume, and it doesn't mean you have to be a vegetarian, it just means including many different plants, even in small amounts like spices, seeds, nuts, veggies, fruit, fungi, and anything else that grows. What you eat primarily beyond a variety of plants is what needs to be individualized for each person, which takes some experimentation, preferably with a continuous glucose monitor or if you are willing to do a finger prick with a regular monitor several times a day after you eat over the course of a couple weeks to see how you react to different foods.
I believe eventually, the future will start recognizing more personalized diets for everyone. You'll give a fecal sample to analyze and map your microbiome and you'll be told what the best foods you should be eating to be at peak healthfulness.
Sorry, I went on a tangent.
I guess I could have said: keep making good food choices, stay well hydrated, maintain a caloric deficit and you WILL burn fat and eventually see the number on the scale change. You body is changing regardless of what you see on the scale.
Don't be afraid to experiment a little with food though.
Good luck, you'll get through it!!
