2018: THE YEAR OF INTERMITTENT FASTING
THIS IS IT! This is FINALLY the year I am going to lose the excess weight and get healthy! YES! I am going to find the latest and greatest new diet, and I am going to follow it like a champion! 2018 will finally be my year!
With your resolution in mind, it’s time to head to the bookstore and peruse the diet books! Of course, when you get there, you find that the NEW diet books look an awfully lot like the OLD diet books. Sure, they have been repackaged and reconfigured, but most of them tell you which foods are dietary heroes and which are dietary villains, and as long as you follow their (probably complicated) plans, you can achieve weight loss nirvana! They tell you what to eat and what NOT to eat, and they generally have phases and meal plans, with a “fabulous” recipe section. Of course, you’ll be sick of these phases and meal plans in a couple of weeks, and you’ll long for whatever foods you have restricted. Over time, you’ll gradually drift back into your old dietary patterns, and the diet is over. Hey! There’s always next year! Maybe 2019 will finally be your year!
What if it is a lot easier than that? What if, instead of the latest and greatest NEW diet, we look back in time to a practice that has been around for so long that most people have forgotten it? Let’s go back to the time of Hippocrates, also known as “the father of modern medicine.” He lived from around 430-360 BC, and is famous for this quote:
“Everyone has a physician inside him or her; we just have to help it in its work. The natural healing force within each one of us is the greatest force in getting well. Our food should be our medicine. Our medicine should be our food. But to eat when you are sick is to feed your sickness.” –Hippocrates
Instead of a fancy new diet that promises to help us Lose 12 pounds in 12 days! Or Drop 3 sizes by Next Tuesday!. why don’t we look to the practice that has been a part of every major religion and culture for millennia. Let’s look to the natural healing force within that Hippocrates was talking about: fasting.
Did I lose you there? Stick with me. I get it: the word “FASTING” carries with it a lot of emotional baggage. You may be picturing emaciated monks or teenage girls with eating disorders. Actually, nothing could be further from the truth. An intermittent fasting lifestyle is not a life of dietary restriction and eating disorders. It’s actually one of the healthiest things you can do for your body, and it’s a lifestyle that will bring you true FREEDOM from dietary constraints and restrictions.
It’s important to understand: I’m not talking about extended water fasts where you aren’t eating for days at a time. In an intermittent fasting lifestyle, you eat every day, and you get to enjoy all of your favorite foods with no guilt. Fun fact: you ALREADY fast every day! It’s true! From the moment you finish eating at night to the moment you eat breakfast the next day, your body is in the fasted state. Congratulations! You are already a faster and didn’t know it. All you have to do to adopt an intermittent fasting lifestyle is to extend your daily fast further into the day. You push back your “break-fast,” and then, you eat without guilt. That’s where the dietary freedom comes in.
So: when you think of fasting, you may have certain concerns right off of the bat. Do any of these come to your mind?
“Fasting?!?!?! You are putting yourself in starvation mode!”
“Everyone knows that breakfast is the most important meal of the day!”
“You must eat 6 small meals per day to keep your metabolism from shutting down!”
Guess what? Not ONE of those statements is true!
Before beginning an intermittent fasting lifestyle, the important first step is to educate yourself on the health benefits of intermittent fasting. Read, read, and read some more, until you are confident.
So, are you intrigued? Let’s get educated!
Many of us begin intermittent fasting for weight loss, but IF is about so much more than just weight management. Even if you never lost a pound, I am convinced that IF is one of the healthiest things you can do for your body. One year ago, the biggest news in the intermittent fasting world was without a doubt the announcement of the 2016 Nobel Prize in Medicine. As written in the press release, Yoshinori Ohsumi “discovered and elucidated mechanisms underlying autophagy, a fundamental process for degrading and recycling cellular components.” What stimulates autophagy? Fasting, of course!
Rather than try to explain all of the benefits of autophagy myself, I am going to share some links that will take you to videos and/or well-written and easy to understand discussions about autophagy, so you can learn about it yourself. Click here to view a video that explains the process and benefits of autophagy, even though it is a bit dry and science-y. The article available here explains many of the benefits of autophagy in straightfoward terms, and this is a powerful quote from that article: “Autophagy is a process of cellular recycling that effectively removes old, damaged, and faulty equipment in our body, potentially stopping cancer, insulin resistance, diabetes, infections, heart disease, Alzheimer’s, inflammation, and even aging.” WOW. Who wouldn’t want those benefits? With a list like that, I think you would have to be crazy NOT to try intermittent fasting, personally. You can read Dr. Jason Fung’s take on autophagy here, on his blog at Intensive Dietary Management. (His explanations are always my favorite.)
Notice that I led with the health benefits of intermittent fasting, because I want you to have that first and foremost in your mind. IF is healthy, and fasting has powerful anti-cancer, anti-Alzheimer’s, anti-inflammatory, and anti-aging benefits. Even if you never lost a pound, it is worth doing for the health benefits alone. BUT–is it crashing your metabolism, as critics warn? Are you putting yourself in danger of slowing your metabolic rate, resulting in long-term damage to your metabolism and eventual weight gain? Fortunately, the answer is NO.
This study is often cited by intermittent fasting experts. From the study: “Resting metabolic rate (kJ/min) was significantly increased after 36 h of starvation…but was not significantly different from the 12 h value after 72 h.” Don’t be alarmed by the use of the word “starvation” in that quote, because they are referring to periods of intermittent fasting from 12 to 72 hours in length. Nobody ever starved to death in 12-72 hours. When you analyze that quote from the study, you see that they found that metabolic rate INCREASED after 36 hours of fasting, and at 72 hours, the metabolic rate wasn’t lower than the metabolic rate measured after 12 hours. Metabolic shutdown? Clearly not! On the contrary–at the 36 hour mark, metabolic rate was UP. Take that, “you’re going to shut down your metabolism” naysayers!
This article does a nice job summarizing much of the thinking surrounding intermittent fasting and metabolism. Of course, as usual, the most entertaining analysis of intermittent fasting and metabolism can be found on Dr. Fung’s blog at Intensive Dietary Management. His classic post is found here (with an accompanying photo of George Constanza, in all of his glory), and Dr. Fung explains how IF not only protects your metabolism, but it can also help reverse metabolic damage brought on by following calorie-restricted diets in the past. This is really important to understand: not only are you NOT tanking your metabolism through IF, you can actually repair damage brought on through other dietary approaches. Keep in mind–this isn’t always a fast process (fasting pun, right there…) If you have been following a restrictive diet long-term prior to starting an IF regimen, expect weight loss to be slow or nonexistent for awhile. You could even gain weight at first, until your body has a chance to heal metabolically. No one wants to hear that, but you should be aware of the possibility if you are a long-term dieter.
1. Fasting is one of the healthiest things you can do for your body! As I shared, fasting stimulates autophagy. This is how your body naturally takes out the cellular trash, and the more I read about it, the more I believe that it’s one of the most powerful things you can do for your health.
2. Intermittent fasting is great for your body metabolically. Rather than slowing your metabolism, which we find in diets that promote long-term calorie restriction, IF has metabolic benefits you miss out on when you follow typical diet recommendations. (I’m looking at YOU, “eat less/move more”…) You can even repair metabolic damage brought about by long term restrictive dieting through fasting, though it takes time.
It’s important for you to realize that intermittent fasting is not some radical new fad diet that is here today, and gone tomorrow. It’s an ancient practice that is seen all around the world and in every major religion. In intermittent fasting, you’re not being asked to go 40 days and 40 nights without food; with most intermittent fasting plans, you are eating until you are satisfied every day, and most people find that it’s a lot more enjoyable than trying to eat tiny meals spread throughout the day. Once you adjust, it’s actually easier than typical diet plans. This is one of those things that most people don’t believe until they try it for themselves.
There’s also one more exciting benefit to intermittent fasting that seems to be universally true: over time, your body will direct you to eat “healthier” foods, and many of your junk-food favorites actually lose their appeal.
It’s pretty empowering to know that YOU are in charge, rather than some sort of diet guru who doesn’t live in your unique body.
Discover the practice that is as old as time and yet still as effective today as it always has been: intermittent fasting.
