Wow… I write about the tingling below but first, I know I’m late since the post is so old, but keto should not be used to lose weight if you have any chance of having a body dismorphia, like when you have anorexia, because it won’t be any different than eating carbs, you will still harm yourself if you go overboard.
If you have an eating disorder in which you seek control, keto will probably will give you that sense of control and could help you reach better eating habits in the long run, but you should not forget your health (physical and mental) comes first. If you are already at a fit percentage body fat, you have to eat enough calories to cover at least your resting metabolic rate so you don’t die and preferably you should always start keto at a maintenance amount of calories for a few weeks. You should never move into a calorie deficit that is so large and unsustainable, that later it makes you binge. It totally defeats the purpose of keto. It’s not meant to be a short term sprint but a sustainable, comfortable eating habit that gives you a healthy life. Make sure that whatever keto plan you choose, it is something that you could stick to long term since you should give your body at least two weeks to stabilize and get it to use the ketones it produces (starting and stopping is probably why you get high ketone readings, they only mark the start of ketosis and go down as you continue).
To answer the question, I get tingling when my electrolytes are off and when I move in and out of ketosis but they are short lived, it could be related to that. Like, when I first started keto, they were bad and if I cheat or purposely plan a carb-up I will feel like little pricks after eating and as I go back into keto. Also, my joints feel a little weird when I change diets. Make sure you not only control potassium and sodium but also make sure you get enough magnesium and calcium. If you also have bulimia you’re probably losing a lot of potassium and sodium when purging so make sure you keep that in mind and up the intake a lot if you do, especially if you feel lethargic. Carbs help retain water and regulate electrolytes, so you might just be eating too few for your body to stay lubricated enough to function properly. Zero carb and even traditional keto can be too little carbs for some people, you might just have to up your overall carb intake during keto. Make sure you drink water if you feel thirsty or make your own homemade ketorade. Also make sure you count net carbs and not the fiber since you just poop that. For foods, eat lots of spinach, broccoli, mushrooms and almonds.
Please seek counseling of both a psychologist and a nutritionist so that they can help you tailor a form of keto that will help you stay healthy and free from anorexia, while still feeling in control. I really hope that you’re doing ok.
