so today I want to answer the question can intermittent fasting change your nutrient requirements it’s not a simple answer of yes or no there’s more to it so let’s take each concept the first thing you need to realize is that when you do in a minute fasting or fasting prolonged fasting you’re living off your reserves unless you’re taking nutrients during that period and by the way I do recommend taking nutrients during the fast because we don’t know if you’re deficient and there’s a lot of variables involved number one what is your current diet when you eat or your doing what one lady said on my show recently internet keto which is like a random selection of pretty much anything as long as it’s low carb there’s so many things that can affect this question number one the food that you’re eating what kind of soils is it growing on a lot of foods in America are basically they look good on the outside they’re really big but they’re empty with nutrients like tomatoes for example it’s taste like nothing and you also have foods that are very deficient in trace minerals like zinc for example or iodine because they’re not grown on soils that they replenish them these minerals and then when you’re on the keto plan or some other plan how nutrient-dense are those foods okay that’s one question what about your history how long have you eaten junk foods junk foods deplete you of nutrients refined foods pull out the B vitamins and minerals potassium especially what about your gastrointestinal tract do you have enough stomach acid if you’re on any acids chances are you don’t have enough stomach acid and you’re not going to be able to break down the proteins you’re not going to absorb the minerals effectively that would be one factor what about the gallbladder let’s say for example you don’t have a gallbladder or you don’t have enough bile you’re not gonna be able to absorb vitamin A de or K as well as you should are you a medication what if you’re on metformin that pulls out b1 or let’s say you’re in diuretics it depletes potassium there’s so many other factors here at stress depletes B vitamins and calcium grains you have the phytates in the fiber and the brand of grains which block zinc for example and other minerals let’s say for example you have malabsorption because you have scar tissue or you don’t have the villi to absorb certain nutrients in your in your intestine because you have IBS or celiac or something like that or you have an alteration in your genes that don’t allow you to absorb certain nutrients it’s called polymorphism and then let’s say for example you’re in keto and you’re consuming less carbohydrates so you’re gonna dump a lot of fluid in water and with that you lose some electrolytes sometimes and also salt when you’re on keto you need actually more sodium you actually need more b2 you need a bit more potassium because your diet has shifted so different things can require different nutrients the other factors that you need to look at is the difference between water soluble vitamins and fat soluble vitamins the water soluble vitamins are not stored very long maybe several days with the exception of b12 ok b12 can be stored for up to a year or more ok and also vitamin C can be stored in the adrenal gland but let’s say for example you have adrenal fatigue and you’re depleted of vitamin C I don’t know if you realize this but if you have no vitamin C for 4 months you can start developing symptoms of scurvy which is kind of an advanced deficiency of vitamin C you have a lot of it’s called classical deficiencies like beriberi which is a b1 deficiency rickets which is a vitamin D deficiency pellagra which is a vitamin b3 deficiency and all of these are very severe vitamin deficiencies but let’s say for example you don’t have those severe deficiencies you have a subclinical deficiency well the body will then ration out certain nutrients for the most important things but not necessarily satisfy the demands for everything in your body so for example if your body is low in b1 it may use it only for blood clotting but not necessarily for DNA repair a cancer prevention so it rations out the nutrients for the most important things based on what it means to survive right now and so these subclinical deficiencies can create long-term health problems the RDAs were meant to prevent these major diseases but not necessarily to optimize all the functions for long-term health so if you have a subclinical deficiency you may end up with a hair loss or have fatigue or have anxiety or sleeping problems because your body is using those things for things that are more important for survival right now so when you’re doing fasting or intermittent fasting you may not show any of the deficiencies for the fat side of a vitamin mainly the water-soluble vitamins and this is another reason why you know when you’re doing keto B vitamins are important now when it comes to minerals and trace minerals they don’t stay in the body for very long okay except certain minerals will like it’s very difficult for your body to get rid of excess iron for example or calcium but the minerals that you use a lot of like potassium magnesium but even sodium but not as much those minerals are used more and your body can get rid of them a lot easier than iron and calcium when you’re doing in a minute fasting I recommend taking two B vitamins as well as these minerals and trace minerals just to make sure now another factor is your microbes your microbes can make certain vitamins like vitamin k1 as long as you have the microbes in there so if you history up taking a lot of antibiotics and you have an imbalance of microbes or you have SIBO which is small intestinal bacterial overgrowth that can alter your vitamin production from your microbes and if you have like inflammation in your gut that can also alter your ability to make vitamins and if you have damage in the lining of your gut in the small intestine or large that can also prevent the absorption of those nutrients your body also makes certain Biba it’s like biotin for example so anyway I just wanted to create this one video to show that’s not a simple answer there’s a lot of things you have to look at you have to use judgment you have to look at your history do I have a reserve of nutrients left in my tissues to pull out of and as my current diet nutrient-dense is it healthy keto or not play it safe I recommend taking B vitamins trace minerals and electrolytes during the fast all right thanks for watching if you’re liking this content
