Starvation mode is a nebulous and rather exaggeratedly villainized creature. It is there, hisses every now and then but doesn’t really bite… unless you consider 10 or 100 fewer calories expended per day to count as biting. You know what the actual killer rabbit is? The 300 calorie smoothie you might end up drinking without registering. Or the fact that you might have set your mind to an exceptionally ambitious goal weight that requires ridiculously few calories and tons of activity per day to maintain. Or well-known medical conditions like metabolic syndrome or thyroid known to tangibly affect our energy expenditure for the worse. Please forget starvation mode exists. It may be intriguing to learn about, like the curious cosmic ray that every once in a lifetime may corrupt a byte in our RAM, but for all practical intents and purposes irrelevant.
It’s fine
I recommend https://www.amazon.com/End-Your-Carb-Confusion-Customize/dp/1628604298, it recommends eating as you are - to satiety, prioritizing protein. It also covers maintenance, key to stopping the yo-yo for me. Don’t do Audible, there are lists that are key. My library had the book.
