AI Summary

Intermittent fasting (IF) is a time-restricted eating pattern where you consume all meals within a specific daily window and fast for the remaining hours. It's not about eating less, but eating less often, and it can support weight loss and various health benefits like improved insulin sensitivity, autophagy, and gut health. This beginner's guide covers the basics, including what you can consume during a fast, recommended fasting windows, and tips for making fasting easier.

[00:34]
Definition of Intermittent Fasting

IF is when you eat meals within a specific time window and fast the rest of the day, consuming no calories during the fast.

[00:55]
IF vs. Caloric Restriction

IF is not about eating less, but eating less often; it's not a diet but focuses on the eating window.

[01:54]
Health Benefit: Lower Insulin

Lower insulin levels allow the body to access fat stores for energy (lipolysis).

[02:52]
Health Benefit: Increased Growth Hormone

Growth hormone supports skeletal muscle, important for metabolism and longevity.

[03:20]
Health Benefit: Autophagy

Autophagy is a cellular cleanup process that requires 14–17 hours of fasting.

[03:56]
Health Benefit: Gut Health

Fasting activates the migrating motor complex, which pushes out undigested food and bacteria.

[04:37]
What Breaks a Fast

For strict fasting (autophagy/gut health): water, sparkling water, black tea, black coffee, electrolytes. For weight loss (dirty fast): small amounts of heavy cream, MCT oil, stevia.

[04:46]
Supplements That Break a Fast

Creatine, collagen, and protein powders break a fast.

[08:15]
Recommended Fasting Window

Beginners should aim for 12–16 hours, gradually increasing. Include sleep hours to make it easier.

[09:52]
Food Tips for Easier Fasting

Eat blood sugar–balancing meals (protein, fiber, healthy fats) to make fasting easier.

[00:00] so many of you have asked me to share a

[00:02] video on intermittent fasting so that's

[00:04] exactly what I'm going to do today think

[00:05] of this as a beginner's guide we are

[00:08] going to cover the basics and I'm going

[00:09] to do my best to really try to simplify

[00:13] the concept and the process now if you

[00:16] don't know me my name is Danny Spees I'm

[00:18] a Health weight and wellness coach and I

[00:20] love helping people make healthy eating

[00:23] easy doable and delicious and before I

[00:27] jump in I'd like to thank element for

[00:29] sponsoring this video and I plan to

[00:30] share more on them in a bit so what is

[00:34] intermittent fasting also known as Tim

[00:36] restricted eating intermittent fasting

[00:38] is just that it's when you choose to eat

[00:41] your meals within a specific time window

[00:45] throughout the day and then for the rest

[00:46] of the day you are not eating at all so

[00:49] you're not consuming any type of

[00:51] calories or any type of energy which is

[00:53] why we call it fasting now intermittent

[00:55] fasting is not a form of caloric

[00:58] restriction in the sense that it's not

[01:00] about eating less it's simply about

[01:03] eating less often although I will say

[01:06] for many people it does result in eating

[01:09] less simply because when you restrict

[01:12] the amount of hours within the day that

[01:14] you can consume food kind of natural

[01:16] byproduct for many people is that they

[01:19] consume less food but not true for

[01:20] everybody and technically intermittent

[01:23] fasting is also not a diet because again

[01:25] the focus is on the eating window not so

[01:28] much the food but I do think it's

[01:30] important to note that the type of food

[01:31] you eat can make your fast feel easier

[01:34] or more difficult and that's something

[01:36] I'm going to talk more about later in

[01:38] the video so why fast there are two main

[01:41] reasons that people choose to experiment

[01:43] with intermittent fasting the first is

[01:45] weight loss and the second is simply to

[01:48] reap the health benefits that are

[01:50] associated with intermittent fasting so

[01:52] let's chat about what some of those are

[01:54] the very first one is that it lowers

[01:56] insulin levels now if you're not

[01:57] familiar with insulin it is sometimes

[01:59] called called the transport hormone and

[02:02] that is because whenever you eat

[02:04] anything your blood sugar Rises also

[02:06] known as glucose when you have glucose

[02:08] in the blood insulin is released to

[02:11] transport that glucose or that blood

[02:14] sugar to the liver to the muscles then

[02:16] eventually to Fat stores now when

[02:18] insulin levels are elevated fat burning

[02:21] or the process called lipolysis is

[02:23] turned off this is why insulin is also

[02:26] known as the storage hormone because

[02:28] when insulin is elevated the body does

[02:32] not have the ability to access fat

[02:35] stores for energy but when insulin

[02:38] levels are lower which happens when we

[02:40] are fasted the body then can access its

[02:43] own fat stores to use for fuel and this

[02:46] is why a lot of people like to use

[02:48] intermittent fasting as a tool to

[02:50] support their weight loss goals another

[02:52] health benefit is an increase in growth

[02:55] hormone Now growth hormones help to

[02:57] support skeletal muscle and as many many

[02:59] of us know as we become older wiser and

[03:02] more fabulous um maintaining healthy

[03:05] skeletal muscle is very important for

[03:07] good health and for longevity and it can

[03:10] also really support weight loss goals

[03:12] because the more lean muscle mass you

[03:14] have on your body the more calories the

[03:16] more energy your body is going to burn

[03:18] another incredible benefit of

[03:20] intermittent fasting is a process called

[03:22] autophagy autophagy is a cellular

[03:24] process where the cells are able to

[03:26] break down and recycle their own damaged

[03:29] components which allows them to get rid

[03:31] of any debris and maintain cellular

[03:33] health and cellular function this plays

[03:35] a crucial role in overall health

[03:38] protecting against diseases and

[03:40] supporting longevity but do keep in mind

[03:42] that in order to reap the rewards of

[03:46] autophagy you need to be fasted

[03:48] somewhere between 14 and 17 hours

[03:52] depending on which expert you follow

[03:54] another benefit is gut health fasting

[03:56] allows your body to turn on a gut

[03:58] cleansing process called the migrating

[04:00] Motor complex now this is a pattern of

[04:03] rhythmic contractions in both the small

[04:05] intestines and the stomach that allows

[04:08] the system to push out undigested food

[04:11] and bacteria and this keeps your gut

[04:13] feeling very happy and healthy fasting

[04:15] is also associated with lower

[04:17] inflammation in the body improved heart

[04:19] health and improved brain health so

[04:21] clearly there are a lot of good reasons

[04:23] to experiment with intermittent fasting

[04:25] should you feel intrigued to give it a

[04:28] try Okay so we're going to talk about

[04:30] fasting windows in just a minute but

[04:31] first I want to talk about what you can

[04:34] and cannot consume when you are fasting

[04:37] because this is a question I get a lot

[04:39] and here's the deal it really depends

[04:41] what your intention is when you are

[04:43] fasting but quick side note I can tell

[04:46] you for sure no matter what your

[04:47] intention is creatine collagen and

[04:50] protein powders will absolutely break

[04:52] your fast that is a question many of you

[04:55] have asked me before because sometimes I

[04:56] put those ingredients in my coffee now

[04:58] here's the deal if you are using

[05:01] intermittent fasting for weight loss

[05:03] many would argue that you could do

[05:05] something called a dirty fast and what

[05:07] that means is that when you're having

[05:08] coffee or tea in the morning that you

[05:10] can add a little bit of heavy cream of

[05:14] coconut cream of MCT oil and when I say

[05:17] a little bit I mean about a tablespoon

[05:19] okay and then for sweetener many would

[05:22] also say that you could do a little bit

[05:23] of stevia because Stevia does not affect

[05:25] blood sugar the way other sweeteners do

[05:28] and the theory here is is that the fat

[05:30] and the little bit of sweetness is not

[05:32] enough to actually raise insulin levels

[05:34] therefore it does not interrupt the fat

[05:36] burning process but technically the term

[05:39] fasting means zero calories which means

[05:41] you would not take anything in that had

[05:44] any calories at all and this is

[05:46] specifically true if you're looking to

[05:48] reap the rewards of gut health Andor of

[05:51] autophagy in which case what you are

[05:54] able to consume and still be in a fasted

[05:56] state would be water sparkling water

[06:00] black tea black coffee and or

[06:02] electrolytes which brings me to today's

[06:05] sponsor element element is an amazing

[06:08] zero sugar highquality electrolyte

[06:10] company that can enhance your daily diet

[06:13] especially if you are fasting or even if

[06:15] you're simply somebody who likes to

[06:17] focus on eating a diet of real Whole

[06:20] Foods with minimal processed foods like

[06:23] myself it contains a science-backed

[06:25] electrolyte balance of sodium magnesium

[06:28] and pottassium that help to replace and

[06:30] balance out electrolyte levels in the

[06:32] body now a lot of people don't realize

[06:35] that very clear signs of electrolyte IM

[06:37] balances include headaches muscle cramps

[06:40] fatigue and sleeplessness specifically

[06:43] in this very hot weather I know here in

[06:45] New Jersey it's well over 90° and

[06:48] personally I feel such a huge difference

[06:50] in both my energy levels and my feeling

[06:53] of hydration when I drink element it is

[06:55] just not the same when I drink regular

[06:58] plain water I literally like crazy I

[07:00] look forward to drinking it every single

[07:02] day now if you were going to drink

[07:04] electrolytes during your fasting window

[07:06] but you wanted to be really careful or

[07:07] really strict then you might want to

[07:09] choose the raw unflavored element

[07:12] packets but I also know that a lot of

[07:14] people will still drink the flavored

[07:15] packets when they are fasting myself

[07:18] included and while I don't fast every

[07:20] day my husband does and he always drinks

[07:23] the uh flavored packets so ultimately

[07:25] that's a decision that you can make for

[07:26] yourself now personally I love the mango

[07:29] chili J and I love the raspberry salt my

[07:32] husband he's an orange salt and a citrus

[07:34] guy but they have so many flavors to

[07:36] choose from including a chocolate Salt a

[07:38] watermelon salt a grape food Salt so

[07:40] many good ones and right now element is

[07:42] offering everybody in the clean and

[07:44] delicious Community a free sample pack

[07:47] with any order that's eight single serve

[07:49] packets with any element order which is

[07:52] a great way to test out all eight

[07:54] flavors so you can get yours at drink

[07:57] element.com

[07:59] any speed this is only available with my

[08:01] link so you want to visit d r i n k l m

[08:06] nt.com back/ d n i s p i s and I'm also

[08:12] going to leave the link for you down in

[08:13] the description box below so how long

[08:15] should you fast for there are different

[08:17] fasting Windows within a

[08:19] 24-hour period usually you will see

[08:22] people fasting anywhere between 12 to 22

[08:24] hours but technically any period of time

[08:27] when you're not eating is considered a f

[08:29] so sometimes we have to just like look

[08:31] where we are and then build upon there

[08:34] often what you will see and I feel like

[08:35] what most experts are recommending to

[08:37] the average person who is new to

[08:39] intermittent fasting is to aim somewhere

[08:41] between 12 and 16 hours so what you

[08:44] would want to do is work your way up to

[08:46] 12 and then slowly but surely add an

[08:49] extra hour until you can comfortably get

[08:51] to 16 hours or comfortably get to

[08:53] whatever fasting window feels like the

[08:55] right balance for you and the easiest

[08:57] way to determine your fasting window is

[08:59] to think about what time you like to eat

[09:02] your last meal in the day and then work

[09:04] backwards so if you like to eat dinner

[09:06] at 700 p.m. then you would not eat again

[09:09] until 700 a.m. the next day and then if

[09:12] desired you can slowly build from there

[09:14] maybe the next day you wait till 8: and

[09:16] then a few days later you go till 9:00

[09:18] and eventually you get to 10:00 but I

[09:20] will tell you this Pro tip no matter

[09:22] what you do always include your sleeping

[09:25] hours in your fast time because that's

[09:27] going to make fasting a whole lot easier

[09:29] and the last piece I want to talk about

[09:31] is food while intermittent fasting is

[09:33] not a diet and is technically not

[09:35] focused on the food but rather the hours

[09:37] in the day when you are not eating food

[09:40] I do think it's important to note that

[09:42] the types of meals you eat within your

[09:44] eating window can affect how easy or

[09:48] difficult your fast is going to feel

[09:50] ultimately the name of the game is to

[09:52] eat blood sugar balancing meals meaning

[09:54] you want to eat meals that are rich in

[09:56] protein fiber and healthy fats and you

[09:59] want to minimize highly processed

[10:01] flowers and highly processed sugars or

[10:03] really any type of food that's going to

[10:05] create a big spike in your blood sugar

[10:08] so good quality sources of protein

[10:10] plenty of vegetables fresh fruits

[10:12] healthy fats like nut seeds and avocados

[10:15] and then of course whole grains based

[10:17] around how you feel and your activity

[10:20] levels and quite honestly this really

[10:22] isn't different than any healthy dietary

[10:25] approach right if you look at all of the

[10:27] different dietary approaches in the

[10:29] world and you look at the through line

[10:31] they're all kind of saying the same

[10:33] thing at the base right let's focus on

[10:34] real Whole Foods as close to their

[10:36] natural POS State as possible most of

[10:39] the time prioritizing protein fiber and

[10:41] healthy fats and if you need some help

[10:43] or a little bit of inspiration with food

[10:45] or recipes or cooking I have hundreds of

[10:48] easy healthy delicious recipes for you

[10:50] right here on clean and delicious and I

[10:52] will also say as this is a kind of a toe

[10:54] in-the water beginner's guide that if

[10:56] this is speaking to you and it's

[10:57] something you feel like you want to

[10:58] experiment with

[10:59] but you're not sure if it's the right

[11:01] decision for you you may just want to

[11:03] consult with your healthcare provider

[11:05] just to get the extra support and

[11:06] guidance that you may be needing okay
