okay I’m back and we’re gonna answer the question how long should a person fast for okay so let’s talk about this ideally you want to ease into this gradually because you want to let your body fully adapt the goal is to run your body on fat-burning and do keto at the same time you’re doing intermittent fasting so you start with 12 hours which is not too hard and then you go to 18 and let your body get used to it and then 20 hours okay and then you’re eating window is about 4 hours a lot of people are doing this right here including myself this is a really good range and one thing I like about this is that with 2 meals you can really easily get most of your nutrient requirements a bunch of people also doing one meal a day they’re doing 23 hours they’ll eat and then they’ll wait another 23 hours ok if they eat in one hour and this is also effective and the amount of nutrient requirements are not near as when you’re doing 3 meals or even two meals so you actually can recycle all these nutrients and proteins so this is fine as well but you just have to kind of graduate and adapt to this right here and this would be really good if someone wanted to improve their metabolism if they have stubborn weight it’s actually great for diabetics to actually help insulin resistance so between you know two meals and one meal is a good option now should you go beyond this well if you do you have to know what the heck you’re doing you have to have a nutritional reserve because recently I had two different people pass out because they did extended fasting without building enough reserves especially electrolytes so they had low electrolytes one guy fell over and passed out hit his nose another person passed out because they didn’t have the amount of electrolytes through the day so they just pretty much pushed through just drank water nothing else and they didn’t have the nutrient reserve that they needed to do this so I don’t recommend going beyond 23 hours unless you know you’re doing and you build up your nutritional reserves okay thanks for watching hey if you enjoyed this video press subscribe and I will definitely keep you updated
