How Intermittent Fasting Boosts the Benefits of the Keto Diet
Ok, so we’ve got the basics of each of these diets down. How exactly do they benefit one another
1. Shift into ketosis sooner
One of the primary goals of a keto diet is to get into ketosis as quickly as possibleand to stay there for as long as you can. When you practice intermittent fasting, your fasted state has already starved your body of carbs, which means your glucose levels are lower than those of someone who doesn’t fast.
This means that when you’ve been fasting, your body will shift to burning fat reserves and ketones even sooner. And that translates to getting you into ketosis much more quickly than if you weren’t fasting.
The flip-side of this is also true. Being in ketosis mimics fasting because your body is burning fat for fuel. So if you’ve been trying an intermittent fasting plan but haven’t really noticed any results, following a keto diet during your eating windows might just give you the jumpstart you’ve been looking for.
2. Lose weight faster
The common core that intermittent fasting and the keto diet share is that they are designed to switch your body from burning glucose to burning fat instead. And when you put both diets together, your fat burning is actually maximized.
Here’s why: if your keto diet has successfully put you into ketosis, then your body has adapted itself to using fat as fuel. When you add intermittent fasting into the mix, your body has a head start on the fat-burning track and will actually be even more efficient at continuing to burn fat.
Compare this to someone who doesn’t follow a keto diet. When they adopt intermittent fasting, their body will be much slower to enter the fasted state, which is where all the fat-burning magic happens.
3. Boost your brain health and mental focus
Did you know that your brain is one of the body’s biggest consumers of energy? It’s true. And it just so happens that fat, not glucose, is the most energy-efficient fuel that your body can run on. Since both intermittent fasting and the keto diet train your body to burn fat for energy, your brain reaps huge benefits from both these plans.
After all, we always have fat stores available to burn. So as long as your body knows how to tap into those fat stores for fuel, your brain has a constant energy source on which to run. This is why people following both intermittent fasting and the keto diet experience more mental clarity, focus, and other neurological benefits. (2)
There’s even more good news for your brain. Studies have shown that fasting boosts production of a protein (BDNF) that feeds your brain stem cells and promotes neural health. (3)
4. Make both diets easier
Let’s be honest, one of the main reasons some of us are skeptical about trying intermittent fasting is that fasting leaves you feeling hungry. A keto diet, however, is known to help decrease cravings and hunger, due to the high-fat content of the keto eating plan ( 4).
So if you’re already following a keto diet, you may find the fasting windows of an intermittent fasting plan much easier to manage. Both eating plans are designed to keep your insulin levels steady, which means less cravings and hunger pangs over the long term.
5. Enhance your exercise
Can you even exercise while you’re fasting? This is a common concern, but the answer is a resounding “yes!” Not only is it okay, but a growing number of studies show that following intermittent fasting and a keto diet can in fact enhance the long-term health benefits of your exercise program.
Both intermittent fasting and the keto diet train your body to burn stored fat for energy. This triggers a variety of metabolic adaptations that will actually increase your workout performance while you’re fasting. (5)
Worried about losing muscle? Don’t be! This study revealed that you can actually maximize your muscle gains when you train while fasting. And this study indicates that when you do strength training in a fasted state, the nutrients you consume afterwards will be better utilized by your body than if you hadn’t been fasting during your workout. Pretty cool!
And for those of you concerned about whether your actual workout performance will suffer as a result of fasting, not to worry. Studies have been done on Muslim athletes who fast for Ramadan, and no negative effect on performance was found. If you do decide to workout while fasting, we recommend you do it right before you start your eating window for the day.

Tips for Starting and Sticking With It
1. Listen to your body
As with any new diet plan or exercise regimen, only you yourself can be the ultimate expert. We are all unique and will respond differently to the same plans.
If you’ve decided to follow a 16:8 intermittent fasting schedule but find yourself really struggling, tired and hungry, don’t hesitate to modify your schedule. Try shifting your eating window to later in the day, or check to make sure you’re getting enough high-quality keto food calories.
If it’s still not working for you, maybe try expanding your eating window to 10 hours, or only practice an intermittent fast every other day.
2. Don’t start both at the same time
So you’re really motivated to take advantage of the potent fat-burning effects that these two diets offer. We get it! But if you’re brand new to both intermittent fasting and the keto diet, it’s not recommended that you try to adopt both at the same time. Trying to master the new eating habits of a keto diet while also sticking to the new schedule of intermittent fasting can be overwhelming, to say the least, which means you’ll be more likely to give up.
We recommend starting with an intermittent fasting schedule for approximately two weeks, so that your body has time to adjust to the new pattern. At this point, your body will also be more adept at shifting into a fat-burning zone, so that when you start eating a keto diet, you’ll likely find it easier to drop into ketosis.
3. Drink tea
Even during your fasting windows, you are allowed to consume as many calorie-free beverages as you’d like. Die-hard keto followers, take note: bulletproof coffee counts as breaking your fast. So if you’re following an intermittent fasting schedule that has you fasting between 8pm and noon, you shouldn’t drink your bulletproof coffee before noon.
The best alternative? We highly recommend tea, as it will not only keep you hydrated, but it also promotes gut health, wards of cravings and assists your body in detoxification.
How the Keto Diet and Intermittent Fasting Can Boost Sports Performance
One of the more surprising aspects of both the Keto diet and intermittent fasting is that some seriously tough athletes claim these eating plans help to increase their athletic performance.
They just might be on to something. If you’re looking to boost your sports performance, here’s what you should know: one of the primary reasons these eating plans work is because training your body to burn fat can help you recover from exercise more quickly. And if you eat a keto diet and follow an intermittent fasting schedule, then your body becomes increasingly more efficient at switching over to fat-burning mode. The easier it is for your body to burn fat, the better your athletic performance and recovery time.
There’s a growing number of endurance and elite athletes who have incorporated fasted training into their programs. Fasting creates a combination of high adrenaline and low insulin levels that further stimulates burning fat for energy. And if you’re looking to add lean muscle mass, regular fasting has been shown to increase growth hormone levels, which helps with muscular development.

Is it a good idea to “starve” yourself just a little bit each day, or a couple of days a week? Mounting evidence indicates that yes, intermittent fasting (IF) could have a very beneficial impact on your health and longevity.
I believe it’s one of the most powerful interventions out there if you’re struggling with your weight and related health issues. One of the primary reasons for this is because it helps shift your body from burning sugar/carbs to burning fat as its primary fuel.
As discussed in the featured article,1 intermittent fasting is not about binge eating followed by starvation, or any other extreme form of dieting. Rather what we’re talking about here involves timing your meals to allow for regular periods of fasting.
I prefer daily intermittent fasting, but you could also fast a couple of days a week if you prefer, or every other day. There are many different variations.
To be effective, in the case of daily intermittent fasting, the length of your fast must be at least 16 hours. This means eating only between the hours of 11am until 7pm, as an example. Essentially, this equates to simply skipping breakfast, and making lunch your first meal of the day instead.
You can restrict it even further — down to six, four, or even two hours if you want, but you can still reap many of these rewards by limiting your eating to an eight-hour window each day.
This is because it takes about six to eight hours for your body to metabolize your glycogen stores; after that you start to shift to burning fat. However, if you are replenishing your glycogen by eating every eight hours (or sooner), you make it far more difficult for your body to use your fat stores as fuel.
Intermittent Fasting — More a Lifestyle Than a Diet
I have been experimenting with different types of scheduled eating for the past two years and currently restrict my eating to a 6- to 7-hour window each day. While you’re not required to restrict the amount of food you eat when on this type of daily scheduled eating plan, I would caution against versions of intermittent fasting that gives you free reign to eat all the junk food you want when not fasting, as this seems awfully counterproductive.
Also, according to research published in 2010, 2 intermittent fasting with compensatory overeating did not improve survival rates nor delay prostate tumor growth in mice. Essentially, by gorging on non-fasting days, the health benefits of fasting can easily be lost. If so, then what’s the point?
I view intermittent fasting as a lifestyle, not a diet, and that includes making healthy food choices whenever you do eat. Also, proper nutrition becomes even more important when fasting, so you really want to address your food choices before you try fasting.
This includes minimizing carbs and replacing them with healthful fats, like coconut oil, olive oil, olives, butter, eggs, avocados, and nuts. It typically takes several weeks to shift to fat burning mode, but once you do, your cravings for unhealthy foods and carbs will automatically disappear. This is because you’re now actually able to burn your stored fat and don’t have to rely on new fast-burning carbs for fuel. Unfortunately, despite mounting evidence, many health practitioners are still reluctant to prescribe fasting to their patients. According to Brad Pilon, author ofEat Stop Eat: 3
“Health care practitioners across the board are so afraid to recommend eating less because of the stigma involved in that recommendation, but we are more than happy to recommend that someone start going to the gym. If all I said was you need to get to the gym and start eating healthier, no one would have a problem with it. When the message is not only should you eat less, you could probably go without eating for 24 hours once or twice a week, suddenly it’s heresy.”
The Health Benefits of Intermittent Fasting
Aside from removing your cravings for sugar and snack foods and turning you into an efficient fat-burning machine, thereby making it far easier to maintain a healthy body weight, modern science has confirmed there are many other good reasons to fast intermittently. For example, research presented at the 2011 annual scientific sessions of the American College of Cardiology in New Orleans 4 showed that fasting triggered a 1,300 percent rise of human growth hormone (HGH) in women, and an astounding 2,000 percent in men. HGH, human growth hormone, commonly referred to as “the fitness hormone,” plays an important role in maintaining health, fitness and longevity, including promotion of muscle growth, and boosting fat loss by revving up your metabolism. The fact that it helps build muscle while simultaneously promoting fat loss explains why HGH helps you lose weight without sacrificing muscle mass, and why even athletes can benefit from the practice (as long as they don’t overtrain and are careful about their nutrition). The only other thing that can compete in terms of dramatically boosting HGH levels is high-intensity interval training. Other health benefits of intermittent fasting include:
-Improving biomarkers of disease
-Reducing inflammation and lessening free radical damage
-Preserving memory functioning and learning
-Normalizing your insulin and leptin sensitivity, which is key for optimal health
-Normalizing ghrelin levels, also known as “the hunger hormone”
-Lowering triglyceride levels
Intermittent Fasting Is as Good or Better Than Continuous Calorie Restriction
According to Dr. Stephen Freedland, associate professor of urology and pathology at the Duke University Medical Center, “undernutrition without malnutrition” is the only experimental approach that consistently improves survival in animals with cancer, as well as extends lifespan overall by as much as 30 percent. 5 Interestingly enough, intermittent fasting appears to provide nearly identical health benefits without being as difficult to implement and maintain. It’s easier for most people to simply restrict their eating to a narrow window of time each day, opposed to dramatically decreasing their overall daily calorie intake. Mark Mattson, senior investigator for the National Institute on Aging, which is part of the US National Institutes of Health (NIH), has researched the health benefits of intermittent fasting, as well as the benefits of calorie restriction. According to Mattson, 6 there are several theories to explain why fasting works: “The one that we’ve studied a lot, and designed experiments to test, is the hypothesis that during the fasting period, cells are under a mild stress, and they respond to the stress adaptively by enhancing their ability to cope with stress and, maybe, to resist disease… There is considerable similarity between how cells respond to the stress of exercise and how cells respond to intermittent fasting.” In one of his studies, 7 overweight adults with moderate asthma lost eight percent of their body weight by cutting their calorie intake by 80 percent on alternate days for eight weeks. Markers of oxidative stress and inflammation also decreased, and asthma-related symptoms improved, along with several quality-of-life indicators. More recently, Mattson and colleagues compared the effectiveness of intermittent fasting against continuous calorie restriction for weight loss, insulin sensitivity and other metabolic disease risk markers. The study, published in the International Journal of Obesity in 2011, 8 found that intermittent fasting was as effective as continuous calorie restriction for improving all of these issues, and slightly better for reducing insulin resistance. According to the authors: “Both groups experienced comparable reductions in leptin, free androgen index, high-sensitivity C-reactive protein, total and LDL cholesterol, triglycerides, blood pressure and increases in sex hormone binding globulin, IGF binding proteins 1 and 2. Reductions in fasting insulin and insulin resistance were modest in both groups, but greater with IER [intermittent fasting] than with CER [continuous energy restriction].”
How Intermittent Fasting Benefits Your Brain
Your brain can also benefit from intermittent fasting. As reported in the featured article: “Mattson has also researched the protective benefits of fasting to neurons. If you don’t eat for 10–16 hours, your body will go to its fat stores for energy, and fatty acids called ketones will be released into the bloodstream. This has been shown to protect memory and learning functionality, says Mattson, as well as slow disease processes in the brain.” Besides releasing ketones as a byproduct of burning fat, intermittent fasting also affects brain function by boosting production of a protein called brain-derived neurotrophic factor (BDNF). Mattson’s research suggests that fasting every other day (restricting your meal on fasting days to about 600 calories), tends to boost BDNF by anywhere from 50 to 400 percent,9 depending on the brain region. BDNF activates brain stem cells to convert into new neurons, and triggers numerous other chemicals that promote neural health. This protein also protects your brain cells from changes associated with Alzheimer’s and Parkinson’s disease. BDNF also expresses itself in the neuro-muscular system where it protects neuro-motors from degradation. (The neuromotor is the most critical element in your muscle. Without the neuromotor, your muscle is like an engine without ignition. Neuro-motor degradation is part of the process that explains age-related muscle atrophy.) So BDNF is actively involved in both your musclesand your brain, and this cross-connection, if you will, appears to be a major part of the explanation for why a physical workout can have such a beneficial impact on your brain tissue — and why the combination of intermittent fasting with high intensity exercise appears to be a particularly potent combination.
Give Intermittent Fasting a Try
If you’re ready to give intermittent fasting a try, consider skipping breakfast, make sure you stop eating and drinking anything but water three hours before you go to sleep, and restrict your eating to an 8-hour (or less) time frame every day. In the 6-8 hours that you do eat, have healthy protein, minimize your carbs like pasta, bread, and potatoes and exchange them for healthful fats like butter, eggs, avocado, coconut oil, olive oil and nuts — essentially the very fats the media and “experts” tell you to avoid. This will help shift you from carb burning to fat burning mode. Once your body has made this shift, it is nothing short of magical as your cravings for sweets, and food in general, rapidly normalizes and your desire for sweets and junk food radically decreases if not disappears entirely. Remember it takes a few weeks, and you have to do it gradually, but once you succeed and switch to fat burning mode, you’ll be easily able to fast for 18 hours and not feel hungry. The “hunger” most people feel is actually cravings for sugar, and these will disappear, as if by magic, once you successfully shift over to burning fat instead. Another phenomenal side effect/benefit that occurs is that you will radically improve the beneficial bacteria in your gut. Supporting healthy gut bacteria, which actually outnumber your cells 10 to one, is one of the most important things you can do to improve your immune system so you won’t get sick, or get coughs, colds and flus. You will sleep better, have more energy, have increased mental clarity and concentrate better. Essentially every aspect of your health will improve as your gut flora becomes balanced. Based on my own phenomenal experience with intermittent fasting, I believe it’s one of the most powerful ways to shift your body into fat burning mode and improve a wide variety of biomarkers for disease. The effects can be further magnified by exercising while in a fasted state.
