November 5, 2019 Doctor Mike On Diets: Intermittent Fasting | Diet Review By William Claassen Articles, Blog 100 Comments – I’ve seen your request, I’ve read your comments so here we go, intermittent fasting. – I am dying to talk to you about this. – I eat for eight hours, and I fast for 16. – I can feel the difference. – Before we get into the pros and cons, and if you should do it, let’s talk about what intermittent fasting actually is. Human fasting is not a new concept by any means. Humans have been doing it for a millennia. Intermittent fasting is just a rebranding of something that we have already been doing. Our bodies enter a fasting state every time we’re asleep. Some people do intermittent fasting and not even know it. I mean, there’s plenty of times where I had a stressful rotation in medical school, or a difficult job in the hospital, where I didn’t have time to eat breakfast. That’s a form of intermittent fasting and our bodies are totally capable of handling this. I know what you’re thinking. I don’t want to starve myself for health benefits. Intermittent fasting is not starving. When you are fasting, your body is using stored nutrients and stored energy forms in order to make your body continue to function. When you’re starving, you’ve run out of those energy sources and are breaking down vital tissues like organs to get that same energy. There are many different ways to go about going on one of these diets and that not only makes it confusing for you, but that also makes it very difficult to do research on it to find out how effective it truly is because if there are multiple ways to do it, we have to be able to test each one of those ways. The 16/8 diet which is not eating during 16 hours of the day. Alternate day fasting where you eat one day, fast the other day. 5:2 where two days of the week that you’re fasting. There’s no hard and fast rule saying that this is the correct way of doing it. You may be wondering how is IF beneficial to me? There’s been a lot of proposed health benefits, many of them have been proven within animal studies or lab models which is not the same thing as being proven in a human model. But they are very promising. Now, those benefits include increased mental sharpness, a favorable hormonal profile, weight loss, decreases of inflammation within the body, decreases of certain diseases within the body. How can IF help you lose weight? You have an increase in growth hormone, a decrease in insulin, and that alone will help you lose weight. Next, because you’re skipping meals or you’re even going days without eating meals, it is very likely that when you look throughout the week, you’ll be eating fewer calories. Our thinking is that during eight hours you’ll eat less than you would if you were eating during 16 hours. Let’s talk about these other health benefits. We know that chronic stress is not good for the body. The body is just not meant to be chronically stressed out. It’s not meant to have a high heart rate, high blood pressure. Intermittent fasting is really a form acute, short-term, mild stress. This time of acute, short-term stress is really good for the body. What can we use as a metaphor here? Let’s take exercise. Exercise is a form of acute, mild stress. What happens after exercise? We have benefits for the brain, we have benefits for weight loss, we have benefits for disease prevention. Now similarly, when you stress your body through intermittent fasting, there are some benefits. More autophagy, which is the removal of cellular waste, more production of neurotropic factors, which protect your brain. And a favorable hormonal profile with increases in human growth hormone and norepinephrine. Let’s talk about some of the shortcoming of IF. Primarily, there’s not enough guidance of what you should eat. We don’t know how many calories, we don’t know what foods to eat on the days or times that you actually are eating. Second, we don’t know which form of IF is best. Third, there are some side effects when you are fasting that people do experience: headaches, mental fog, heartburn, these things do exist, it’s not totally benign. Four, we don’t know the consequences of following an intermittent fasting diet long term. Most, if not all, of these studies are done on the short term. If you are eating a very unhealthy diet and then make a change you’re definitely gonna see a benefit But now does this benefit still hold up one, two, three, 10 years down the line? We don’t know that yet when it comes to IF. And five, it’s not easy for everybody to fight off those cravings on fasting days. All righty, my final take on IF, I think it is a great concept with some really promising medical research behind it. I think that if you can skip a meal, you can skip a breakfast here and there, you’re gonna see some benefits. Does that mean you should go on this very rigid diet where you’re doing the five and two or 16 and eight? I don’t think we should quite make this a religious, rigorous part of our everyday life because we don’t know the long term consequences of it. But in a society that is prone to overeating, a fasting day won’t hurt and will probably help. As always, stay happy and healthy. So here we go, intermittent fasting: kind of ate the word intermittent, it was like borderline. Our bodies have adapted to this sort of fasting period because of throughout the millennia, blah, (growling) May people are doing this already and not not… Our bodies are totally capable and have adapted to not being filled with food 24 hours of the day.

September 25, 2019 Reply Laila Schneider I never eat after 9 pm and I don't eat breakfast before school (I'm eating again at 2 pm) but if I don't eat at 2 pm, then my blood sugar is rushing down and I'm forced to eat/drink (diabetic type 1). I'm on a diet since 4 months and I already lost 5 kg (I'm not overweight, I just want to take down some weight, eat healthy and build up some muscles after that) but I'm so stressed out, because I often have school in the afternoon and I don't eat in school. Eating the right meals is so hard, so I am looking for a way that I don't have to eat during the day. Is anyone a type 1 diabetic and has some experience with fasting?

October 1, 2019 Reply TheyCalledMeT it's called breakfast because you break fasting October 1, 2019 Reply Bruce Hearn I retired 31 December, 2015. I weighed 270 pounds, give or take (6' tall). Since then, I significantly reduced crappy carb intake. I began time-restricted eating. Breakfast consists of half-a-pot of coffee, neat. I can usually count on one hand the number of sugared soft drinks I drink in a year. Water, unsweetened tea and neat coffee are my drinks of choice. I'm down to 230 pounds and have every intent to continue losing weight. My perfect weight is 165 pounds but I think that unlikely at 62 years of age. I'd be overjoyed to attain 190 pounds. Three more years and I should be there. My diet isn't the best and I don't exercise nearly enough but I hope I can get off of diabetes and blood pressure control meds.

October 5, 2019 Reply akhi nur Very good October 5, 2019 Reply Jorge Hidalgo I love fasting best thing ever. Amazing feeling. and keep me in good shape. October 5, 2019 Reply 801 Cichlids In the beginning of the video you stated that IF isn’t a new thing and has been a reality since the beginning of ages, then at 4 minutes you went on to say we don’t know of any long term side effects or effectiveness in the diet. That kind of threw me off. The way I see it is since the literal beginning of time humans bodies were only meant for IF, we are meant to be hunter gatherers going days between meals, our bodies have not been in their prime because of the ease of access and convenience of food being everywhere. I can’t see IF ever being detrimental to our bodies. Correct me if I’m wrong… I’m sure certain health problems like diabetes can’t sustain an IF diet, but if we were on IF since birth I doubt diabetes would even exist unless there was some form of pancreatic damage.

October 6, 2019 Reply Alia Ris I do circadian fasting, which kinda reversed from common IF, since I just skip dinner. I don't really aim for weight loss, but more of a better balance on hormones and insulin, as well as fixing my insomnia. So far, it's a wonder . I don't feel midday fatigue anymore, and I could sleep normally — albeit a lil bit earlier, and it has been undisturbed at all. I stop my craving, which usually happen in late afternoon, by drinking coffee and a lot of water, and stop seeing any foodporn. It's not for everyone, I understand. There has been some people that also do extreme fasting for a couple days in a week, like 24 or even 72 hours of no meal. Imo, I won't try it, since it's a bit bordering to eating disorder, and being someone with body dysmorphia, it could do more harm for me. Eat healthy doesn't mean you have to punish yourself.

October 8, 2019 Reply Kayn The Cosmic shadow Bruh we muslims been doing this for a month each year lmao but for us we aren’t allowed to drink as well October 9, 2019 Reply Brandon Swink 3:36:Side Effects: Yes you will experience side effects, that’s just within the first couple weeks of fasting though. That’s your body cleansing, actually fully detoxing and that’s why people will experience those symptoms. Because of all the bullshit we have put into our bodies and how frequently we have been eating over the last how ever many years. Your body when fasting is changing into a whole new mechanism. From using glucose for fuel to using ketones for fuel, a much healthier fuel source that provides more energy than glucose. Once you become fast adapted you will only experience those same symptoms if you consume junk again. What you put in is what you’ll get out.

October 10, 2019 Reply Three Jewels Pork shill. October 10, 2019 Reply Mr Shelby Man. Really honest. Loved it. October 11, 2019 Reply Chris Nero I've been doing IF since February and I've lost alot of weight like 60 pounds in 8 months. I also work out 6 days a week during that period of time as well. This diet is one of the hardest to maintain in the beginning stages because as someone who has always been obese and has had struggles with my diet this puts a shock on your body. Kind of makes you feel as though you are a drug addict. But the benefits are amazing I feel better less cloudy thoughts and overall more energy. Some of the downfalls he speaks of are true I do have headaches from time to time. Also have some really bad cravings that I give into sometimes as well. Also forgot to mention that I dont just throw food in my mouth for 8 hour window either I eat one big meal ranging from 1000-1700 calories then call it an evening. So if you are eating more then three meals worth of calories in the 8 hour window might give you different results.
