Reviewer: Tanya Cushman What if I told you that breakfast
being the most important meal of the day was wrong? (Laughter) What if I told you it is more important
when you eat than what you eat? Perhaps much of the nutritional dogma
that we’ve been raised with is now outdated, like snacking all day long
and eating many meals. Over the next few minutes,
I plan to discuss with you what I believe to be the most profoundly
transformational concept and strategy as it pertains to health and aging. Over the last 20 years, as a nurse practitioner
and a functional nutritionist, I’ve seen tremendous shifts, tremendous shifts in health and wellness: escalating rates of obesity, diabetes
and cardiovascular disease – many of which are preventable. The choices we make in terms of nutrition
are profoundly impactful on our health, more than most of us realize. During my training as a nurse practitioner many years ago, the dominant nutritional paradigm
was exercise more, eat less. I’ve found this
to be profoundly ineffective for most, if not all,
of my female patients. The concept of “calories-in,
calories-out” alone is just not effective. Many of the things that I work with,
with my female patients really focus on the connection
between our lifestyle choices and how that impacts healthy aging and weight gain. I do not believe, nor do I support,
the limiting belief that women have to accept weight gain
as a normal function of aging. The National Health
and Nutrition Exam Survey, which looks at data
with regard to children and adults in terms of their nutrition
and escalating obesity rates, compares what went on in the 1970s, where most Americans
consumed three meals a day and no snacks; fast forward to today, most of what we are doing as Americans
is eating three meals a day and snacking all day long. Really. And so one of the things
that starts to happen when healthcare providers
are telling our patients that we need to eat all day long – it’s wrong. Eating all day long overtaxes
our pancreas and our digestive system. It overtaxes it so much
that it cannot work properly. And if it cannot work properly,
we cannot absorb our food or the nutrients in that food. Another really important distinction
when it comes to meal frequency, or how frequently we’re eating, is the debate over sugar burners
versus fat burners. And when we’re talking about that, a sugar burner is someone
that consumes lots of carbohydrates and taps into glucose
as their primary fuel source, which is incredibly inefficient. If you recognize these individuals: They are frequently hungry. They often get hangry. They have – yes – significant dips
in their energy level. They struggle more with fat loss,
and they struggle more with their weight because insulin levels are high. Insulin is that fat-storing hormone. So if levels remain high,
we have more oxidative stress; we have more inflammation; and we struggle more with weight gain. In sharp contrast to this are fat burners. They tap into fat stores for energy; they have sustained energy; they are much more clear cognitively; they don’t get hangry; it’s easier for them to lose weight because they tap into those fat stores; they sleep better;
and they age more slowly. So meal timing and how frequently
we are eating – it’s absolutely crucial. Absolutely crucial. Let’s talk about some statistics
as they pertain to women and healthy aging. So we know two-thirds of women
40-50 years of age are overweight, and more than half are obese. How do we proactively
address this statistic without quick fixes? It makes me want to cry when my female patients
would prefer I write them a prescription than work on changing their diet, more exercise, other lifestyle changes. Women in their 50s and 60s
gain an average of 1.5 pounds per year. Per year. That’s average. And some of this is attributable
to things like hormonal fluctuations, women having less lean muscle mass
than their male counterparts, sleep disturbances and mood disorders. However, there are strategies
we can use to help offset this. So folks, I want you to save your money on potions and powders and supplements
that are not long-term solutions. I’ve got a better idea. And I’m going to tell you about it. I’ve got a better idea. There are lots of strategies
that I use with my female patients, but none more powerful
than intermittent fasting. Intermittent fasting
can help fuel fat loss as well as many other benefits
that I’ll talk more about in a second. But it also can improve
interpersonal relationships and self-esteem. And for many women, this permits them – it’s the magic bullet that allows them
to gain back their former selves. Really powerful. And the really cool thing
about intermittent fasting is it’s free, it’s flexible and it’s simple. You take nothing else away. Free. Flexible. Simple. So let’s talk about intermittent fasting. It is the absence of food
during a prescribed time period. You exist either in a fed
or a fasted state. I’m sure for many of you,
you had breakfast this morning. So when you eat, insulin
is secreted by the pancreas to move sugar into the cells. We store the bulk of our sugar
in our liver and our skeletal muscle. But when we exceed those storage sites, we store it as fat. When we’re fasted, insulin levels are low and we can tap into fat stores for energy. Free. Flexible. Simple. And so, when we’re talking about
intermittent fasting, it’s fairly simple. If you skip breakfast – If you skip breakfast in the morning, you can reduce your caloric intake
by 20 to 40 percent. And the typical time frame
that I recommend to my female patients is a 16:8. Sixteen hours a day fasted
with an eight-hour feeding window. I know that seems
a little overwhelming at first, but I’ll give you some strategies
for how you go about doing that. So, the 20-40 percent
reduction in calories means that you can fuel fat loss. So what are some of the benefits
other than fat loss – fat loss and especially visceral fat
around our abdomens, around our major organs? We know that it improves mental clarity
because insulin levels are low. We know that it spikes
human growth hormone, which helps us with lean muscle mass. We know that it induces
something called autophagy – I will speak more about this in a second. But this is spring cleaning for the cells. It is only evoked when we are fasted. Autophagy. We know that it lowers insulin levels, blood pressure, improves our cholesterol profile. And we know that it can reduce your risk
for developing cancer and Alzheimer’s disease,
which I like to call type 3 diabetes. If, for no other reason,
we want to protect our brains. As wonderful a strategy as this is,
it is not for everyone. I’m going to talk briefly about the individuals
that want to avoid this strategy. First and foremost,
if you are a brittle diabetic, or you have difficult-to-control diabetes; if you are a child, an adolescent
or age greater than 70 – might not be the best strategy; if you are pregnant; if you have chronic heart issues,
kidney or renal issues – not the best strategy. If you have a history
of a disordered relationship with food, whether it is anorexia,
bulimia or binge eating – might not be the best strategy
because it can invoke those tendencies. And last but not least,
if you have a low body mass index, you’re frail or you’ve recently been in the hospital
like I was for 13 days. I’m not currently intermittent fasting. Now, everyone always asks, Well, when you’re fasting,
we know we’re not eating food, but you can absolutely consume things
like filtered water, plain coffee or tea. They will not break your fast. But when you’re ready to eat,
what do you eat? Now, I would be remiss
if I did not mention that there are foods that are going to be more
advantageous for you to consume when you’re ready to break your fast. So I want you to focus
on real whole foods. That’s what your body needs,
wants and deserves. So I want you to purchase the best quality
protein that your budget permits. Ideally, organic or pastured meat,
wild-caught fish. Healthy fats – so crucial – helpful for building healthy hormones and also really important for satiety –
making sure our taste buds light up, make us happy. I’m not part of the anti-fat brigade. Really, really important. Twenty years ago, I might
have told you not to eat fat, but now we know better. So I want you to focus
on things like avocados, coconut oil, grass-fed butter and nuts –
really great, healthy fats. Unprocessed carbohydrates. Ladies, absolutely crucial, if you’re in perimenopause,
the five to seven years before menopause, or you’re in menopause, quality and quantity are crucial. So I want you to consume things
like low-glycemic berries, green leafy vegetables, squash,
quinoa, sweet potatoes as opposed to bread and pasta. Cautionary tale: I want you
to limit sugar and alcohol. By that I mean, I want you
to not consume those things because they can offset
all the good that you’re doing. And lastly, keep yourself well hydrated. Now, I want to make sure that I briefly touch on
some of the practical implications for how you would go about
starting intermittent fasting. Generally, I have my ladies
start with 12-13 hours of fasted period. And they can slowly increase
by an hour or so every day until they’ve reached that 16 hour mark. Again, you want to keep yourself
really well hydrated. You can also have plain coffee or tea. In addition to that, you want to ensure
that you give it a solid 30 days before you determine
if it’s the right strategy for you. And if you have chronic health conditions, I want to make sure you discuss it
with your healthcare provider. Really important. And recognize it may take
six to eight weeks to really see the full benefits
of what you’re doing. The biggest pain point
for my female patients is weight gain. I have a fantastic strategy
to help with this, but I don’t want you to buy into
the next $50 container of protein powder or the hottest weight loss
supplement that’s out there. I want you to think about the fact
this is a simple, flexible and free option that you can try at home, discuss with your healthcare
provider if necessary. I really feel so passionately about this because it’s something that all of us
should be discussing with our patients. Thank you. (Applause)

  1. How many prediabetics can actually skip bfast and not get dizzy for work? I gotta have my coffee for inspiration, so there must be something to go with it. Can't drink coffee with just fruit either! No sir. Not pretty. I can sleep for 12 hours though. 🙂

  2. Intermitentt Fasting is Just amazing I have doing through 5 Months, I and can see how the muscles 💪 grow fast

  3. Wrong!!!… and tea will have to be metabolised by the Liver 100% thus at that point you are not in a fast….keep your fasting window water only….

  4. Doctors told me for years I was overweight because I didn't eat breakfast and was skipping meals. Now since I've been eating breakfast I've gained 30lbs 🤷🏽‍♀️ I'm going back to skipping meals

  5. If you are at your wits end and looking for the best diet on the planet that is NOT keto or freaking Atkins then you owe it to yourself to check out Bright Line Eating – specifically designed for those who have addiction and addiction to food. It works where all other diets fail. Seriously you will thank me for this. There are also Facebook groups you can join for support. I've been on it for 40 days now and I've lost 19 lbs. Check it out – for the first time in a long time I have hope that I can overcome my eating addiction. If you're thinking of intermittent fasting you can also use it with Bright Line Eating.

  6. It took a few months to get my health care provider onboard …with my keto and fasting….she kept doing my blood work. Now after me being 47 lbs down and my thyroid numbers being normal, she keeps asking how to do it (for herself) and writing everything down. 🙂 she's amazed.

  7. As a follower of the Islamic faith Fasting 30 days a year is compulsory and I have been doing it since I was a teen. However what most people don't know or don't follow in practice even Muslims, is that Prophet Muhammad recommended fasting 13th 14th and 15th of each month. Or better still every Monday and Thursday or even better still one day fast next day eat as normal and continue this cycle permanently . Imagine the benefits?

  8. 5 months of Intermittent fasting/fasting @ 45, I now have excellent blood pressure and cholesterol. I am now at 5-11 158lbs and can jog 10 miles. I was at 200, high blood pressure, high cholesterol, sore joints and body aches.

  9. Cynthia: Calories In vs Calories Out is not the answer.
    Also Cynthia: Intermittent fasting decreases caloric intake by up to 40%.

    Sit down, Cynthia.

  10. I used to fast just by nature of sleeping 9 hour days and then not going to anywhere with food until 4 or 5pm. This was during college when I was barely ever working out, just a few pushups between episodes on a Netflix binge, and I was eating 3 ice cream sandwiches a day and 2 rods of raw cookie dough a week. I was already skinny and still lost 5 lbs and ended up more toned and muscular than I had ever been after doing that for an entire semester. Yeah, it works really well.

    That said, this woman doesn't know what she's talking about telling diabetics not to fast. If they do keto, diabetics not only can fast, they should. It'll keep their blood sugar level and can even mitigate the effects of their diabetes, by and large

  11. الحمد لله على نعمة الاسلام
    الاسلام عرف الصيام وفوائده منذ 14 قرناً

    Thank God for the blessing of Islam

    Islam has known fasting and its benefits for 14 centuries

  12. Personally, from my experience, it's still about calories in / calories out; however, IF makes it easier to reduce calories in because you simply have a shorter window to eat. Also, disclaimer, I'm not yet in menopause. That could totally change when it hits.

  13. Does it matter if some days my feeding window is more than 8 hours as long as my fasting period remains a minimum of 16?

  14. Fasting only works if your still eating less (calorie deficit) if not your wasting your time it's basic physics. thermodynamics.

  15. I drink lemon in my water all day long. Would I be able to use fresh lemon in my water during the hours that I can't eat?

  16. I'm 13 days in with fasting 16:8. I'm doing it because I needed to learn to control my cravings. I have discovered that I have a strong will power after turning down food during my 16 hour fast. I'm eating less junk food and during my eating window I'm making better choices because I'm aware of what my body needs. I have a lot more energy and feel much happier. I have lost 5 pounds but that's not the main reason why I started so if I lose or stay the same I am happy.

  17. Totally agree with the video. People have a food addiction. Its a sin. Its called gluttony. It leads to suffering.

  18. Great topic, but four minutes in, I had to stop watching. I wish the speaker would stand still and not pace. It's a detraction from her important message.

  19. I started IF about 10 days ago and am down 6 pounds.. I didn't make any changes to my lifestyle but bear in mind I do go to the gym and on walks… I also eat pretty clean generally. I'm not vegan or vegetarian but I do avoid dairy products aside from plain yogurt and some cheeses (and even that is once in a while). I think I can lose more if I get better at drinking more water! Going to do it for at least 60 days before I take another "after" update! Overall I feel amazing and more focused. Also saves a lot of money haha.

  20. IF works because it regulates total caloric load. She makes it sound like eating breakfast is deadly. I do IF when I travel and on busy mornings but if I get hungry at 10am, I eat. I guess I'm damaging my pancreas.

    And thanks for mentioning that binge eaters should NOT do this.

  21. Tried some time ago – weight loss, decreased food cravings and a sense of well-being. Definitely to be combined with exercise. On the downside evenings with family can be hard when others are enjoying snacks or having a meal together. People should be taught the health benefits of fasting at school.

  22. Wow. I'm a small-boned woman who is 64 and has been hovering between 135 and 145 for decades. After less than 2 months doing 16 hour IF, I am down to 122 and feel and look GREAT. Easy system. I no longer measure calories or totally eliminate pasta and bread from my diet. I still have a glass of red wine most evenings. THANK YOU!

  23. I am pregnant and Keto/IF most days. This is the best pregnancy I have ever had! I feel amazing, and baby is doing awesome.

  24. She starts out saying that calories in/ out didn't work at all for her female clients. I'm concerned with this because it does work for a lot of ppl including myself. I want to know how many clients she had and how closely they were counting calories. Just because IF works doesn't mean Calories in/out doesn't and vice versa. That start really left a bad taste from the jump. Also, doesn't being on IF or restrictive eating help facilitate consuming less calories?

  25. Great talk! Reinforced and clarified things I’ve read and heard elsewhere. I little sad that I think she’s saying I’m breaking my fast by having having almond milk and honey in my morning tea but it makes sense

  26. I’ve been IF to improve my energy levels and mental clarity. It’s been 4 weeks and I feel so much better than before I started.

  27. I really just enjoy the feeling of taking control of my eating habits as opposed to eating at every temptation. I am over 40 so with a slower metabolism now only fast every second day but for 20hrs to get the best of the HGH increase.

  28. Wait… in my humble opinion, a safe diet/eating lifestyle would be safe for ALL those conditions listed as not ideal for IF. No?

  29. Great talk on intermittent fasting. I wanted to check that it would be okay to begin whilst breastfeeding? My baby is not a newborn but he is under one-year old. Thanks

  30. Great talk on intermittent fasting. I wanted to check that it would be okay to begin whilst breastfeeding? My baby is not a newborn but he is under one-year old. Thanks

  31. I wake up and have my superfood smoothie … so is it best that I wait to have that at the 16 hr window?   I'm 55 and would like to lose 25 lbs please

  32. What if I told you that breakfast being the most important meal of the day was wrong?I would say, what took you so long? Martin Berkham (Lean Gains) had this figured out years ago. And before that, Ori Hofmekler gave us the warrior diet.

  33. She is correct but a little late on the news. Keto came well after Atkins. And now these people jump on the bandwagon as a MeToo speaker. Correct again, but a little late to the party,

  34. Intermittent fasting is nonsense, there is not any scientific proof. Just eat less calories and be physical active that’s all that matters. Nothing new..

  35. Dr. Jason Fung has been preaching this for over a decade.He specializes in kidney disease with an emphasis on Type 2 Diabetes. If you want to reverse your Insulin Resistance or your type 2 diabetes or you simply want to lose weight and keep it off, then search his name on YouTube. He explains why intermittent fasting works and how it works.

  36. I am doing intermediate fasting is the best option, I lose 25 pounds I feel with alot energy and healthy, I eat everything except spaghetti, bread and rice but This is amazing, I highly recommend.

  37. Want to see half to full lb a day results?? Go keto and combine with IF. Bam. Watch it fall off and your energy increase. Steer clear of fake sweetners as well. Most increase glucose/insulin reaction breaking ketosis anyways. Just go natural and carb restrictive with the idea as humans we arent designed to be constantly pumping food thru our bodies. Good luck 👍👍😊

  38. Very easy dont eat breakfast. Only do lunch and dinner in a 4hr window within a 24hr time frame daily. You will lose weight and maintain your metabolism ect..

  39. I just started my intermittent fast 3 days ago and already my body feels better. I don't expect to lose a whole lot but I'm paying this with keto so I'm hoping for the best.

  40. I've just finished my first week of intermittent fasting, I was fasting for 20 hours and eating (good & not too much food) window of about 4 hours or less, I was 100% committed, I stepped in the scale after a week and guess what😶😶 I have GAINED 💔😭😭😭HALF a kilo. I am not sure what's wrong, soo upset.

  41. I tried IF and lost 4kg very easily, doing 16:8 starting at 7 am finishing at 2 pm, but then I started feeling very tired and drained, bloated and moody. I also got terrible cramps. I thibk its because I would consume a lot of carbs and sugars during my eating window. I dont do it anymore but the negative effects remained. I gained the weight back and havent been able to lose it since. I think I am one of those sugar burners. I want to try again but I'm afraid it won't work. I dont think my eating window was ideal so I might switch it up although it will be tough because I've always eaten breakfast in the morning.

  42. interesting that this talk is about how the body can be healed, while she is wearing spike high heels one of the worst things that wreaks havoc on the body in many ways – perhaps she should consider the whole and not the part in terms of the bodies needs !

  43. Just make healthier eating choices and cut out juice sugary drinks, sodas and not eat the bar/shake supplements. Just eat real food. Add exercise and get your sleep hours. Unless you are physically unable to exercise I can see how this may work. Youre not doing any harm if you are choosing nutrient rich foods to eat during whichever hours of the day. Eat for fuel.

  44. Everyone is so weight focused, hardly many comments mention other factors of their function and feelings. Sad that even an 'anti-diet' eating routine still has people obsessed with their weight and no, I am not a fattie, just observant of how people attain their self-esteem from their relationship with gravity!!

  45. Just ask a gastric bypass patient how little food a person can actually survive on. Three meals plus snacks is a full on consumerist LIE. We spend every waking moment with our cephalic phase activated because of constant bombardment from food ads. Just think of the money wasted on all that excess food we don't need to buy.

  46. I've been following fasting research since the early 90's. There's a lot of evidence in support of controlled fasting (a lot of woo/BS now as well as people glom onto the idea). I do recommend it, if done intelligently. I'm a registered nurse

  47. I lost 20 lbs in 3 months with intermittent fasting. I only needed to lose 27 to be at a healthy weight and BMI. It does work if you do it correctly!

  48. I like how she says “lastly, keep yourself well hydrated”

    Girl that is a firstly, lol. That is literally the most important thing for a human body to do. Especially Alkaline water produced from a machine.
