Kind: captions Language: en today I'm going to talk about intermittent fasting and present A Simple Guide for beginners uh and this is the topic that you've heard I'm sure a lot about uh everywhere from social media to uh television they probably talking about the health and wellness uh tips for dieting with your friends so uh let me try to break it down for you in simple ways that uh I think anybody will be able to understand and also give you some really simple tips on how to actually do intermittent fasting and use it to your Health Advantage the first thing I need to tell you is what fasting is fasting is a term that describes the state of not eating all right when you're eating you're not fasting when you're fasting you're not eating when you decide after you're fasting and not eating for a while when you actually decide to break your fast meaning stop your fast uh you're going to be eating again right that's what we call breakfast all right so intermittent fasting is the most natural thing we do as humans because during the day we are eating all right and while we're eating a lot of met metabolic things are going on I'm going to explain that to you in a second um and we're going to be eating breakfast lunch and dinner uh the food is actually our fuel uh the fuel we actually our metalism stores into our muscles it's it's in our bloodstream and we actually store it in our fat our fat is our fuel tanks all right and then when you're done eating uh a bunch of things have to happen uh in order to process that food but then at the end of the day before you go to bed and you're not eating for a longer period of time your body senses that that's going to be it you're done with food and then when you go to bed uh you are not eating right when you're sleeping you're not eating all right most people aren't eating and uh that's the longest period of time where we are not eating and your body um uh recognizes that and your metabolism shifts gears into fasting mode all right so you're not eating when you're sleeping your body senses that and shift into fasting mode uh when you're actually sleeping all right and there's all kinds of other things that are actually happening there we're going to talk about that uh as well okay so eating during the daytime you are not fasting uh when you finish your last meal and your body then senses you're not going to be having any more food your metabolism shifts gears um uh from storing the fuel to burning the fuel and now you're fasting and you're fasting the whole time that you're actually sleeping okay so there's a lot of things that are going on during this period of time and I am going to actually explain to you the steps so it can make sense to you but I want to mention that intermittent fasting which is not fasting all the time but fasting intermittently which is what we do we sleep at night we're fasting we get up in the morning and then we eat during the day and then oh it's evening again we're going to start fasting again that's intermittently fasting all right if it wasn't inter and all you were doing is fasting you'd be on your way to starving so uh let's say that you Don e for a day that's a pretty long fast extend that to two days or three days um that's pretty extensive um there are people who actually practice intensive fasting uh that way there might be some health benefits for some types of situations to do that kind of fasting but then uh if you were to be stuck in a desert island all right or Stranded by the side of the road uh where where there's no food you keep on going you're actually without eating you're actually going to be starving and then eventually your body will consume itself you'll get skeletonized and that's the Continuum all right eating is for fuel uh fasting is between periods of fueling up uh and you want to break it every now and so you're intermittently fasting every every single day of existence now this idea of actually extending your intermittent fasting for a period of uh longer than just overnight actually has been recognized for hundreds of years religious practitioners like monks across different types of religions actually spent portions of their year fasting right that's that's supposed to be virtuous um and actually if you think about these monks wind up actually being pretty healthy overall they're actually not sick they're actually pretty healthy so something is actually happening during this period we're fasting um our body doesn't punish us for fasting it actually rewards us for fasting and this is actually why hman fasting is not just a health Trend it's actually something profoundly beneficial to our organism our bodies and it has to do with our blood glucose uh and and how our metabolism actually uh works all right so we're going to talk about this now all right first let's talk about what happens when you're eating so you can understand by contrast what happens when you're fasting when you're eating during a day uh you're we're eating our food um our food provides us the fu all right uh basically we're loading up on fuel so we have enough energy our body requires energy just to be in existence not to mention washing the dishes going for a walk down the street taking a meeting all those things take extra energy and then I'm not talking about going to the gym I'm not talking about uh you know working out those are whole other levels of energy so we we absolutely need energy and that's why we eat our food is our fuel and just like a car where you actually need to fuel up on a regular basis um you want to choose the best quality of fuel as well all right so this is a topic for a different video but I just want to mention that when you're eating uh the fuel for your body's energy like a car that you're filling up with gas you want to choose the best possible Fuel and that's what we're talking about plant-based Foods organic foods Foods uh and avoiding you know things with ultrapress foods and microplastics and all those harmful uh elements you don't want to be putting that into your fuel tank all right now how does your body draw that fuel in well when you're eating um and glucose is getting into your bloodstream that's the fuel um your insulin Rises insulin is a hormone made by your pancreas uh and and there's another hormone called a dipine they work together and basically when you're eating food these hormones come out and they're like ah look glucose levels are rising I don't like to use the word Spike that's actually a triggering word glucose levels R normally your insulin comes out all right with a dip and Ne and they're like okay time to draw that fuel into the tank we'll leave a little bit in the bloodstream and into the muscles for for you to do whatever you need to do we're going to start storing it all right and so our body during the day when we're eating our metabolism is focused on storing fuel not burning fuel but storing it you're going to be burning some of it anyway but when every time you're eating your you're storing it on your last meal and you'll be doing this three times a day or however many meals you eat and even snacking but on your last meal at dinner all right what's going to happen is that you're going to be done with your dinner so let's say that you have dinner at 7:00 um and you might have dinner earlier you might have dinner later I'm just going to use this as an example you have dinner at 7 o'clock most people in most countries like the one I live in you know eat dinner for about an hour I I know there are many cultures that eat take take their time to eat in a more relaxed way it's probably healthier honestly but uh um let's say that you start eating at 700 you finish eating by 8 you put your dishes away and now you don't uh eat anymore that's it you're done now what happens is that your blood glucose is actually um going up normally because You' just eating fuel you the food has fuel it's going to rise at your bloodstream your insulin which has been working all day basically said all right let's go draw that blood sugar back into the body leave a little in the bloodstream bring into the muscles and everything else we're going to store into body fat and when you uh don't eat again after that all right I mean talking about no midnight snack no Munchies uh while you're sitting and streaming or whatever you're actually doing uh watching television um that's it you're done with dinner uh eventually the insulin levels will go back down because the glucose has been taken care of all right you don't you don't need to draw any more fuel there's no more fuel to be had inside levels go down and now it's a long enough period of time now your body your metabolism senses hey that was the last meal so it shifts gears your metabolism shifts gears from fuel storing which is what you do during the day it shifts gears into fuel burning mode all right so from fuel storing mode during the day when you're eating because your food is your fuel and you got to store it to fuel burning mode that's when your um insulin goes down when insulin is up your body is focused on storing when insulin goes down which is when you've had your last meal now you're ready to go to bed and you're your body senses the insulin levels are going down that's why you don't want to have a midnight snack now your body shifts gears like a race car at your body and now it is switching from fuel storing to fuel burning mode so if you don't disturb that uh you know uh before you go to bed and then you're going to fall asleep your body is going to be in fuel burning mode that's that's an amazing thing a lot of people don't realize is that when you're fasting at night when you're sleeping when you're not eating when you're fasting your body your metabolism is actually burning down fuel so you're actually losing weight without having to work out just by sleeping seems like a paradox but actually no this is actually how the body is actually hardwired to actually work this is how your metabolism actually works so let's say that you go to bed at 11 o'clock all right you might go to bed later earlier but let's use 11 we know that you're supposed to get eight hours of sleep this is what all the research has shown if you want to actually find a kind of a happy uh uh number to say this is about the right amount of hours for everybody for you to get good some good sleep actually it's different for every individual but you know on average it basically seven to eight hours is what's been shown in in human studies to be beneficial all right that's eight hours of no eating that's eight hours of insulin being down that's eight hours of your body shifting into gear into fat burning mode and during that time you know the f it's actually burning it's burning fat from your harmful excess visceral fat so while you're sleeping you're burning away that harmful fat excess fuel right uh that's actually a good thing you want to burn away burn that away uh and um and all the way into the morning and then when you wake up and we've all been trained to wake up and eat breakfast right away right that that that's what my mom taught me but actually when you wake up in the morning you've been fasting all night let's say eight hours or more because got to add those hours you didn't after dinner uh you get up and you break your fast all right by sitting down having breakfast so you're you're going to have high quality fuel high quality food for breakfast you know coffee is good fruit is good yogurt is good those are all high quality sources of fuel and then your um metabolism your your glucose goes up insulin goes up metabolism shifts gears back into fuel storing mode from fuel burning mode mode while you're sleeping to fuel storing mode when you're up again after that intermittent fast you're up again actually uh eating food again and and then you just kind of do that again and again every day when you're awake and eating your your metabolism your insulin is up your metabolism is in fuel storing mode and when you go back go down and you're sleeping your metabolism shifts into fuel burning mode all right now I've just given you like a really really simple way to look at what's actually happening um between day and night uh sleeping and being awake right and the thing is that during your everyday uh life when you're awake or asleep that is uh intermittent fasting you are intermittently fasting all right that's how simple uh intermittent fasting is okay but that actually doesn't get at sort of the Arts of intermittent fasting or the way that you might actually intermittently fast to optimize your health so given what just told you now let me actually give you a few tips on how to actually tweak the process so you can get the most out of it all right and I'm going to first talk about ways that are very reasonable to do not very uh uh not a big not a big ask uh to be able to actually uh do that um so the first um kind of hack I'm going to tell you is that uh when you're eating during the day again please eat high quality food food we're talking about plant-based Foods healthy oils uh uh nuts and seeds and legumes and herbs and spices right and don't eat too much because don't forget the more you eat the more calories which is the energy you're putting into your body the more you got to store it all right the harder your body actually has to work now most people overeat and you just want to have just the right amount to eat so what I always say is that whatever your eyes tell you to put in a plate take only 2/3 of it all right and if you feel full um don't e all of it you can quit the clean play club and that's fine all right so this is what's happening when you're eating you're eating good quality food you're not taking too much um and you're happy to step away from the plate even if there's some food left on it because you're full all right listen to your body that's really really important you don't never want to overload on fuel but Hey listen what happens when you're at the filling station with your uh car filling up the gas or petrol uh what would happen if you didn't have the clicker on the nozzle and you just kept on filling up the tank right it would fill up and fortunately now we have the clicker goes click and now you know that the gas tank is full but if you didn't actually uh have that clicker the gas tank would fill up and if just kept on putting in fuel okay uh and just for our bodies we keep on eating what's going to happen on the car is that the fuel is going to spill out of the tank run down the side of the car around the tires pool around your feet and now you're standing in the middle of a dangerous toxic flammable mess same thing that happens in our body when you overload in your fuel the body is uh overwhelmed okay it'll keep on stuffing fat cells and by the way this is actually how you gain weight when you overeat so back to intermittent fasting good quality fuel eat smaller amounts uh that you would than you would actually need to uh and um uh when you actually are at the end of the day uh and you're eating your last meal when you put your dishes away that is it don't be eating anything else when you put your dishes away you have made a statement that you are no longer going to be eating anything until the next day so let's do a little bit of math to show you just how powerful this can be right so let's say that you eat at 7 o'clock in the evening and you finish eating it at 8 dishes go in a sink at 8:00 and let's say you go to bed at 11:00 so between 8 and 11 if you're not eating anything all right your blood glucose is going to go up your insulin is going to go up then it's going to come down when it's actually absorbed everything and now you've got three hours with your insulin down 3ish hours your insulin is down your body's going to say hey I think that was the last meal let's go shift gears so you get three hours uh where you're already starting your fast now let's say you sleep for uh 8 hours starting at 11:00 you go to bed at 11: right so 8 hours U from 11:00 is uh 7 in the morning right okay so uh now you've had 8 hours where your insulin's down your body shifted gears into burning fuel not storing it we're going to add those three hours that you got by after dinner not having a snack afterwards so you've got 3 hours plus 8 hours that's 11 hours and then let's say you get up at 7:00 in the morning because that's eight hours to sleep and you don't do what your mom told you to do all right our our moms all told us to quickly get out of bed roll down to the kitchen eat some breakfast hurry up you're going to need some nutrition some food in your um uh stomach so that you can actually use your brain at school and learn something right look we're adults we don't need to do that let me just tell you let's say you get up at 7 o'clock in the morning and you don't eat anything right away take an hour between the time you eat and before by the time you actually sit down for breakfast at least all right and uh uh you know for me take a shower take my time getting ready might check my email might read a couple of pages of a book might open a door and go for a brief walk okay just there's a lot of things that you can do to fill up an hour from getting up and sitting down to eat so let's say you got up at 7 o'clock and you're not going to eat until 8 o' in the morning all right doesn't matter where you are either at your home or your office or wherever let's do some math 8:00 dishes in the sink the night before 3 hours okay then going to sleep for 8 hours 3+ 8 hours is 11 hours now I told you you get up in the morning don't eat for an hour take your time to do something else all right so 3 plus 8 is 11 plus one more hour it's 12 hours okay that's how easy it is to actually fast for 12 hours and by the way 12 hours is half of the day 12 out of 24 hours half the day and you've actually fasted for half of your existence right then and there that is actually the easiest way to do intermittent fasting to get 12 hours of not eating and the rest of the 12 hours you can actually eat now I know the teaching of intermittent fasting is to actually do 16 hours of not eating and eight hours um of eating now for most people that seems like kind of difficult to do I'll give you a really simple way to do it so do everything I just said all right put your dishes away don't eat anything the night before get your three hours and you're 8 hours it's 11 hours um now you got one extra hour okay now it's 12 hours guess what if you actually skip breakfast don't eat breakfast today just skip breakfast now I skip breakfast frequently I have to say because I'm my schedule is so crazy and busy and sometimes they're just not that hungry all right by the way you can have a cup of coffee or or or a cup of tea as long as you don't put dairy in it that doesn't break your fast all right coffee and tea by themselves don't break the fast but let's say that you skip breakfast all right you skip breakfast at 8: or 7 or 8 8:00 um and you don't eat lunch until noon right so from 8 to noon that's 4 hours all right uh so if you skip your breakfast and you do what I just said you had 12 hours of fasting and then you're skipping breakfast you get four more hours that's 16 hours boom you got your 16 hours just like that by not eating anything after dinner the night before by sleeping 8 hours by getting up and skipping breakfast and eating at noon the next day very very easy peasy that's actually how you can actually expand your fasting time where your metabolism is shifted into fuel burning mode all right which burns fat fat burning mode good for your health lowers inflammation all right resets your metabolism makes your insulin your body more insulin sensitive your glucose gets drawn uh in a lot uh easier we don't have time to go through all the different all the science about that but trust me um the longer you actually extend your fast the more you have a chance to reboot your metabolism and let your uh body uh streamline the metabolism and we're actually burning fat and by the way this is actually why intermittent fasting works it's so simple you're just burning down extra fuel you're going to burn down fat okay your good fat will burn down your bad fat you're going to lose weight all right it that definitely does work uh and um as long as you eat healthy during the periods that you are eating good quality Fuel and then here's another little tip that I think is really going to be important when you finally do eat let's say you eat breakfast all right so you're going to do 12 hour fast overnight or let's say you skip breakfast and you decide to eat at lunch after that period of time you know you're going to be pretty hungry all right that's how your body's wired as well your body craves fuel you never want to actually not have enough fuel at that those are the signals uh the hormonal signals in our brain got to load up right that's like the like when you're driving a car and you you don't think about the fuel until every now and then you glance at that fuel meter and if you start seeing it's going towards empty all of a sudden that's all you can think about is that getting to a filling station same thing in our body all right our we have our fuel gauge in our brains and we kind of sense in our metabolism we're actually running low so when what then what happens you get hungry then you're seek food all right so let's say you go for breakfast um whatever you do you're going to be hungry do not overeat do not overeat because when you overeat you're adding extra fuel that you're going to have to burn off later and the more you add on you add on EXT you eat extra for breakfast you eat extra for lunch you have a big snack in the middle of the afternoon then for dinner you had a lot of extra man you know how much energy it's going to take to actually burn down all that extra Fuel and by the way if you've been doing doing this day in and day out week after week and maybe year after year you got a lot of extra fuel on board it is going to take a while to actually burn that extra fuel down and this is why people have gotten into this fat of intermittent fasting which is very natural but the longer you fast the more fuel you're actually going to burn down that's how it basically Works check this out I got a free guide of the five drinks to help remove fat from your liver and it's free I walk you through why your liver is so important why should take care to make sure it's functioning properly in your body and the five drinks I recommend to enjoying to support it all you have to do is click on the link below and enjoy so here's what I was I'm trying to get at when you're actually um uh eating again after the fast please don't eat too much be really aware that you're going to be hungry and if you wolf your food down and take seconds and all that stuff you're just going to be overloading yourself and you're going to be paying for it later on because now you got more fuel to burn off that you didn't have all right one step forward two steps back you just overloaded yourself now you got to do harder work later on to be able to burn off that fuel don't do it um and so how do you actually not do it well first of all uh if you uh take your time to eat rather than wolf your food down your stomach when it's stretched out well and the hormones that are there will actually a signal to your brain also takes a little self-discipline so you're just reminding yourself yeah you you know I'm I'm hungry but I'm I'm just not going to overeat and then if you eat with people by the way uh which is how the healthiest cultures in the world um healthiest food and dietary patterns like Mediterranean or in some places in Asia people usually eat together when you eat together you tend to eat a little more slowly and tend to um be mindful when you're eating and savoring the food enjoying the meal then you're likely not to overeat and then what happens is that your when your when your body will adjust and it'll sense fullness and then you're not going to want to eat again all right you'll slow down and stop eating very very important tip not to over uh actually e once you have breaking after once you're breaking your fast high quality food always all right now there are some foods that you should avoid when you're doing intermittent fasting to try to get the most out of it right because your body's doing all the heavy lifting so you're just adding fuel into the system system or in a case during the fasting time not adding fuel to the system letting your body burn down the extra but you don't want to make it harder for your body to burn down or add too much more fuel and so these are a few things that you want to avoid when you're intermittently fasting avoid Ultra processed foods all right Ultra processed foods the stuff in a box in a can you know stuff that your grandmother wouldn't recognize as food if you showed or the ingredient label uh by the way that ingredient label they've got 20 plus ingredients and you can't pronounce u many of them and you have no idea what they're there for that's a red flag that that's probably an ultra processed food all right so always look at the ingredient label to get your own Comfort level and that's actually what I call an informed food consumer when it comes to ultra processed food so cut down or cut out Ultra processed foods if you want to get the most out of aitt fasting all right stay away from soda both regular soda and diet soda are not good for your metabolism regular soda because regular soda has a ton of added sugar to it all right like and all that added sugar in a soda uh is just flooding your system with calories it can overwhelm your system all right notice I'm not talking about sugar spikes I'm just talking about over flood flooding your system with fuel you don't want to be doing that all right unnecessary and they're called empty calories because you're going to get a lot of calories a lot of fuel but just no polyphenols there's none of it there's no dietary fiber and so forth in the time you could have actually swapped it out with some else you're you're jipping Yourself by only getting uh the the extra fuel all right um uh that's for regular soda for diet soda turns out that many of the artificial non-nutritive sweeteners that they put into diet sodas they actually damage your gut microbiome all right not a good thing for metabolism your gut microbiome is very sensitive when you feed it dietary fiber and polyphenol some colorful foods for example microbes the back healthy bacteria love it and so they're actually pumping out these anti-inflammatory short chain fatty acids they're helping the immune system your text messaging our brain and helping us get into a better mood all kinds of goodness there all right but if you actually take artificial sweeteners and you damage the gut microbiome and by the way it's not just artificial sweeteners artificial coloring artificial flavoring all those things that you find in these Ultra processed foods and sodas now you get a problem because when you damage the gut microbiome inflammation goes up all right insulin sensitivity can go down your blood lipids that should go up and then you're you're not in such a great mood because your gut microbiome the healthy gut microbiome is no longer healthy and no longer text message in your brain um uh to release the social hormones all right all really really important so um uh cut down ultrapress Foods avoid sodas of any kind regular soda diet soda all right um all really important uh to be able to actually uh think through for things you want to avoid and um you also want to avoid um processed meats you know these are the deli meats that we all grew up with you know for school you know that they served in school for lunch or we brought to lunch uh moms packed them into the uh lunch box unfortunately what You' find in a delicatessen those salami and balone and all the things that I remember in my childhood they are not good good for you they're filled with saturated fat um bad for your cholesterol they're they're very salty bad for your blood pressure and there are other substances there not just nitrates or nitrites um that actually been shown to be carcinogenic all right and so processed meats are considered by um the World Health Organization to be a class one carcinogen all right so cut those out as well if you want to be overall healthy and then a final little tip I'll tell tell you is just to be careful about um eating Foods when you're eating that um come in plastic I know it's so hard to avoid that everything seems to be packaged in plastic um in a bag uh plastic is everywhere in our environment but we are now beginning to discover just how much plastic actually gets into our body microplastic the tiny little microscopic pieces of plastic are found in our bloodstream now they recently found them in our brain you can actually take a brain out put it on a scale and you can measure how much plastic is in the brain not good all right and while we don't know the consequences exactly are in the brain probably not very good consequences we do know that there's a correlation we've just been just been discovered of having Plastics in your blood vessels specifically the areas that are your blood vessels that are um narrowed in uh cardiovascular disease that uh if people with cardiovascular disease have plastic embedded in their plaques that's a Nar the area of narrowing they have a four-fold increase of having a fatal heart attack or stroke all right so my last tip to you is you know not about intermittent fasting directly but actually uh just about how to actually get the high quality fuel when you're actually eating is so avoid foods that come packaged in plastic and when you're storing them overnight don't store them into a plastic bin go get a Pyrex glass storage area that the top can be plastic that's fine but make sure that the contact um with the food overnight when you're storing it is actually with glass or Pyrex that's actually a really important thing as well all right so I hope you've learned something new about intermittent fasting for those of you who are newbies to the topic it's pretty easy to do right not not hard at all pretty common sense and actually you're taking advantage of your body's natural fasting State when you're actually sleeping and you can extend it a little bit on both ends in order to get uh where where you want to be and it works it works as it's based on sence you will lose weight you will have a better metabolism it's all going to be good and while you're fasting by the way your gut microbiome your Healthy gut bacteria also has a chance to uh reboot itself so it can be healthier uh and help to protect your immune system uh your brain function brain health your cardiovascular system your metabolic system as well it's all really really good and all really really easy to be able to do so again I hope you learn something new thanks very much
