11 Remarkable Health Benefits of Fasting

11 Remarkable Health Benefits of Fasting

Many people mistake the practice of fasting with starvation, especially in the United States where food abundance and the idea of being hungry is perceived as a negative state (or altogether inhumane, something only happening to the ‘less fortunate’). The truth is, fasting and starvation are two completely different things. That's why we put together this list of 11 remarkable health benefits of fasting... but before we dive in, a few other background points.

Starvation deprives you of nutrition and begins the process of breaking down your body, while the benefits of fasting on the other hand, are as long as they are deep. Fasting is a time-tested and controlled state that is not only beneficial to your health, it’s essential for creating optimal health, managing chronic diseases, reaching a healthy weight for your body type, reversing aging and much more. That’s why we’ve compiled this list of the benefits of fasting… the healthy way, as recommended by Dr. John Limansky, the Keto Doctor… Heads Up friend and advisor. Thank you Dr. John!

  1. Achieve your optimal weight. Different than starvation, fasting gives your body a chance to burn the energy from food instead of storing it as glycogen or fat. During longer fasting periods your body will burn through the glycogen stores and then begin burning fat stores.
  2. Overcome insulin resistance and balance blood sugar levels. Fasting gives your cells an overdue break from insulin so that they can ‘rediscover’ their sensitivity, overcome insulin resistance, and use glucose more effectively. That means blood sugar crashes along with your sugar cravings, taking the strain off of your overworked pancreas while significantly reducing your risk of developing type 2 diabetes. 
  3. Increase metabolism by as much as 18%. It’s been long-believed that fasting will bring your metabolism and weight loss efforts to a grinding halt. The good news is that’s no longer true. Research now shows that a stress hormone called norepinephrine increases during fasting, releasing fatty acids from the fat cells, making it faster and easier for your body to use its fat stores. 
  4. Keep cortisol levels in check and better manage stress.
    Remember the research that suggested that your cortisol response depends on having glucose in the blood? In those same studies, participants who fasted and drank water had a much lower cortisol response than their peers who drank glucose solution. This indicates  that fasting keeps cortisol levels low, helps us to respond to stressful situations in a much healthier manner, and protects us from the harmful effects of chronic stress.
  5. Reduce inflammation by inhibiting the immune response.
    Inflammation occurs in response to pain, injury and/or disease, and in some cases, your immune system continues releasing inflammatory chemicals even after the original state is gone. Such sustained exposure to those chemicals can create other chronic disease states, but fasting helps inhibit that prolonged immune response and blocks the continuing release of inflammatory chemicals
  6. Regenerate your immune system from the inside out. When you fast, your body saves energy by recycling old or damaged white blood cells. This drop in white blood cells flips a ‘regenerative switch’ in the body, stimulating the production of new stem cells. These stem cells then go on to develop into new, healthy immune cells, meaning you’re essentially regenerating a whole new immune system.
  7. Improve heart health by reducing blood pressure and LDL cholesterol.
    Fasting is shown to reduce blood pressure and harmful LDL cholesterol, and it also helps to maintain a healthy weight and reduce the risk of diabetes. It also reduces heart disease risk by protecting your vascular system. 
  8. Improve brain health by stimulating the production of new neurons.
    Fasting stimulates the growth of new neurons and increases production of a hormone called brain- derived neurotrophic factor (BDNF). Altogether, this helps to protect against depression, improve brain function and memory, slow cognitive decline, and reduce the risk of neurological disorders like Alzheimer’s.
  9. Protect against cancer.
    Cancer is characterized by the rapid and uncontrollable growth of cells. Although further studies are needed to confirm this, fasting is believed to help prevent cancer by depriving cancerous cells of the essential hormones they need to grow. Insulin Growth Factor, or IGF-1, is one such hormone, which goes into decline as soon as you stop eating. 
  10. Increase cellular turnover and regeneration.
    Fasting sends your body into cell recycling, a process of self-digestion at the cellular level called autophagy. But you’re not just digesting your fat to fuel yourself while fasting. Your body also targets malfunctioning cells and old tissues to optimize resources for survival.
  11. Improve sleep quality.
    New studies show that routine intermittent fasting in many ways helps the body stay well aligned for sleep and strengthens the circadian clock. That means it’s easier to fall asleep and stay asleep so you can wake feeling more rested.

Is it working? Track it and see.

The best way to understand how your body is responding to fasting, no matter what plan you’re on, is with hard data. Getting an app that collects your key health metrics along with tracking your fasting cycles is not only an easy way to track progress and see how you’re changing, it’s also a fun and motivating method to stay on track. 

The Heads Up app, for example, offers a fasting timer, along with a dashboard to track weight, body fat percentage, sleep, blood sugar, ketones and other vital health metrics, giving you a holistic view of your health before, during and after fasting. Start with their 30-day free trial to connect your other health data, then select an affordable monthly plan to continue tracking your metrics over time.

Should you fast?

With so many metabolic health benefits that are now research backed, it’s hard to say fasting doesn’t have some benefit to most people, however, it’s important that certain demographics should not fast at all, such as those with diabetes or other chronic disease, those who are pregnant or breastfeeding, the elderly and children. Most importantly, check with your doctor before starting any new diet regimen. 

Once you decide to give fasting a try, check out all the various fasting routines to get a sense of what type may be right for you. Not all fasting plans are right for everyone. The other key will be to find a useful tool (e.g. web or mobile application) that you can use to track your fasting plan as you go, and as importantly, to track your key health stats during the fasting state. 

This will be a good indication of how fasting will work for you, and how it impacts your health day to day. It will also be the perfect data to offer to your doctor as you work to achieve your personal health goals over time. 

The big picture? Fasting can become a steady and ongoing part of your healthy lifestyle plan for the long haul, rather than just a diet fad. 

As with any healthy lifestyle plans, consult with your health practitioner first.

Which Keto Tracker App is Right for You?

Which Keto Tracker App is Right for You?

The ketogenic diet has gone mainstream, and with it, so have the number of apps available to efficiently track your progress. But finding the right keto tracker app can get complicated and confusing quickly. There are big differences between free tracking apps with basic functionality and premium apps offering a broader range of keto diet tracking plus other useful features that help you more easily monitor and manage your overall health, no matter what your goals.

So here are some useful tips to help determine if a free keto tracker app is right for you, or if you may want a little more ‘spice’ in your ‘keto app sauce.’

The Freebie Options

MyFitnessPal

MyFitnessPal is a popular calorie counter web and mobile app for tracking fitness and food intake. This keto tracker app diary feature couples with the calorie counter to help track every calorie, nutrient and vitamin you consume. The macros feature helps you analyze eating patterns to determine where you may be out of balance so you can make necessary adjustments to stay on track with your goals.

  • The Pros: MyFitnessPal is convenient to use with easy access to a huge database of foods and information, offering instant feedback and flexible diet plans. It also integrates with other health dashboards as well as a host of other activity, fitness and lifestyle apps as well as wearables (see all integrations). 
  • The Cons: The food database has many listings that are not verified, which can make it hard to find the right food in their system. There is also more emphasis on calories versus macros, and for some, not having net carbs displayed without running a script can make it less keto-friendly than other keto tracker apps. The app also requires an internet connection to access the database in real-time. It may be best suited for those who are steadfast in their dedication to calorie counting as the best method to reach their goals. 
  • Cost: Free; in-app purchases on Apple watch
  • Platforms: Web app and mobile app on Apple & Android

The Bottom Line

The list of keto diet tracking apps is wide and long, and clearly, there is a lot of overlap between options, especially when it comes to the free ones. The pack begins to separate when you get into the more robust paid options that offer a deeper, feature-rich experience. So the best way to choose…?  Start with the end in mind. If it’s a diet plan and you’re on a budget, free is the way to go. But if you want to monitor more health stats over the short and long term, then upgrading to a paid solution will be way worth the investment in monitoring your broader health metrics. 

Tracking the Oura HRV Coefficient of Variation (HRV CV)

Tracking the Oura HRV Coefficient of Variation (HRV CV)

Written by Andrew Flatt, Dave Korsunsky and Chuck Hazzard

Overview

We’ve released an experimental feature in Heads Up Health which automatically calculates the HRV coefficient of variation (CV) based on the data from your Oura ring.

Why track HRV CV?

Looking at daily HRV readings enables you to note short-term fluctuations relative to your baseline. This can be useful for observing the effects of various stressors and lifestyle factors which can help inform on behavior-modification strategies to optimize your HRV.

Due to daily fluctuations, an isolated (i.e., single time-point) HRV measure may not truly reflect an individual’s typical HRV. Thus, some researchers and practitioners are moving towards averaging a series of daily measures to better characterize one's autonomic activity. In turn, most HRV apps are now reporting a rolling weekly average of your HRV values.

Tracking the rolling weekly average provides a better indication of whether your HRV is actually changing in a given direction. In addition, instead of reacting to an isolated change in HRV, a more conservative and convenient approach would be to react only when the rolling average starts to change. One low HRV reading may not be of much concern and would have little impact on the weekly average. However, a series of low scores will reduce the rolling average and may indicate that it’s time to do something about it.

Along with your rolling weekly HRV average, further insight can be gained by monitoring the Coefficient of Variation (CV) among the rolling HRV values. This is because the magnitude of HRV fluctuations can change from week to week, with or without out much change in the rolling average. How much your HRV fluctuates on a day-to-day basis is quite meaningful. Large fluctuations increase the CV while smaller fluctuations lower it.

Interpreting HRV Coefficient of Variation (HRV CV) values

Typical HRV CV values range from 2 - 20%. If we were to take a random sample of adults and measure their HRV for a week, we would probably find that individuals who are younger, healthier (i.e., without disease), leaner and more aerobically fit will fall on the lower end of that range and less-healthy individuals on the higher end.

Regardless of what your CV is at a given time, it’s important to know that it can and will change. Now, whether an increase or decrease in your CV should be interpreted as good or bad is entirely context-dependent. We’ll use some practical examples to explain.

Among healthy individuals, an increased CV is typically associated with greater stress, fatigue, and lower fitness. Vice versa for a lower CV. Thus, the CV is a useful value for assessing adaptation to a new fitness program or lifestyle change. For example, unfamiliar stress will typically cause greater fluctuations in HRV (i.e., increased CV). However, as you become familiar with the new routine, there should be less fluctuation (i.e., decreased CV) which is a sign of positive adaptation. What was once quite stressful to your body is no longer as stressful.

Reductions in the CV are typically good, indicative of increasing fitness, lower stress (or improved stress tolerance) and so forth. There are exceptions, however. For example, suppose your new training program or work schedule is overbearing. Accumulating stress causes an initial increase in your CV. As things continue, your healthy eating habits start to wane, your sleep deteriorates and you become rundown. In this context, your HRV readings may become chronically suppressed, failing to bounce back to baseline. Thus, your rolling average has now decreased, as has your CV.

How we calculate Oura HRV CV

At the time of this post, Oura currently does not report the HRV CV in their app. Thus we are calculating this in Heads Up Health using the average HRV value during the sleep cycle as reported by the Oura app:

Oura HRV Coefficient of Variance (CV)

Figure 1: Oura HRV Average

Using these average HRV values we then calculate the Oura Coefficient of Variation (HRV CV) as follows:

  • Calculate the natural logarithm (ln) value of the nightly HRV average as reported by the Oura app (figure 1)
  • Calculate the mean and standard deviation from the prior 7-day HRV values
  • Divide the standard deviation by the mean
  • Show as a percentage

Note: Some experts in the field have suggested a more accurate method would be to look at the Oura HRV readings from the deep (slow wave) sleep states or by looking at the HRV readings just prior to waking. We are open to changing our approach here based on feedback from users. Feel free to send us your comments.

Tracking Oura CV in Heads Up Health

You can now add the Oura CV metric onto your Heads Up Health dashboard:

Add the Oura HRV CV to your dashboard

Figure 2: Add the Oura HRV CV to your dashboard

You can also graph this marker on the Analyzer next to any other health metric to explore your own correlations:

Compare your Oura HRV CV metrics on the Analyzer

Figure 3: Compare your Oura HRV CV metrics on the Analyzer

Moving the needle

Why would these numbers increase or decrease? The CV reflects the fluctuation in your day-to-day HRV over the last 7 days. High or low HRV readings relative to your baseline will, therefore, contribute to a higher CV whereas more consistent or stable HRV readings will contribute to a lower CV.

Why is lower better?

When the rolling average is stable or increasing, a lower CV reflects less disturbance in autonomic homeostasis. This may mean that you are experiencing less stress or simply coping with it better.

The CV must always be interpreted in context. For example, a night of high-quality sleep may increase HRV well-above baseline, contributing to a higher CV. In a situation like this, the elevated CV is obviously not reflecting higher stress. In addition, stress is important as it stimulates adaptation. Therefore, an increased CV is a normal response to a greater or novel stimulus. However, repeated exposure and adaptation to the stimulus should provoke smaller HRV fluctuations over time and therefore a lower CV. Here, the reduced CV reflects an improved ability to tolerate and recover from the stressor and thus a capacity for greater stress.

Important lifestyle factors which can affect HRV CV

Any factor that alters HRV from baseline contributes to an increased CV. Common factors that affect HRV include:

  • Travel/jet lag
  • Physical stress such as high-intensity exercise
  • Mental and emotional stress
  • Over-training / injury
  • Sleep quality and quantity
  • Illness
  • Drastic changes to daily routines
  • Pain
  • Blood sugar fluctuations
  • Hydration

Heads Up Health can help you holistically track these other lifestyle factors to help identify areas that need attention.

Summary

The HRV CV is another powerful biomarker we can use to further understand how we are managing the stressors in our daily lives. Heads Up Health now supports this metric. This is an initial implementation and we will further refine this feature as required.

Tracking the Glucose Ketone Index

Tracking the Glucose Ketone Index

In this post we will examine the "glucose ketone index" as a biomarker for tracking metabolic health. We will also explore some of the primary use cases for tracking the glucose ketone index including cancer treatment, weight loss, metabolic disease management and athletic performance. Lastly, we will demonstrate how you can use Heads Up Health to track the glucose ketone index along with all of your other important health data.

If you want to skip ahead, click the button below to create an account with Heads Up and start tracking the glucose-ketone index alongside all of your other health metrics. Or, read on for more information on tracking the glucose ketone index.

Track your GKI!

What is the Glucose Ketone Index?

The glucose ketone index is simply a way to measure the relationship between your ketone levels and your glucose levels at any moment in time. It is measured by dividing your blood glucose level (mmol/L) by your blood ketone level (mmol/L). The result is a single number we can use an indicator of one’s metabolic state.

The index has its roots in brain cancer treatment, where researchers using metabolic therapy found best results when glucose and ketones maintained a very precise relationship in the patient [1]. Since there are many aspects of daily life (stress, exercise, nutrition etc.) that can upset glucose or ketone levels in the body, thereby throwing off the optimal glucose-ketone ratio, the index was developed to ensure both metrics (glucose and ketones) are maintaining the ideal ratio for optimal treatment outcomes.

Example: If my fasting blood sugar first thing in the morning is 4.6 mmol/L (82 mg/dL) and my ketone reading is 0.8 mmol/L, I would record a glucose ketone index of 5.75 (4.6 / 0.8).

Despite its roots in cancer treatment, the index can also be very helpful for those using metabolic therapy to treat (and prevent) diabetes, obesity, cancer (particularly cancers that express aerobic fermentation) and other metabolic conditions. By using an index that tracks glucose and ketones TOGETHER, we can develop zones that are optimal for addressing various health conditions.

The table below outlines some generally accepted zones of treatment using the glucose ketone index:

GKI value Degree of ketosis Degree of dysfunction
<1 Therapeutic ketosis Epilepsy
Cancer
1-3 High ketosis Type 2 Diabetes
Obesity
3-6 Moderate/functional
ketosis
Insulin resistance
6-9 Low ketosis Optimal health
Maintenance
Weight loss
>9 No ketosis

Table 1: Optimal zones for the glucose ketone index [2]

Use cases for tracking the glucose ketone index

1. Cancer treatment
For those using metabolic therapy as a means to fight cancer (e.g. brain and other cancers that express aerobic fermentation), the index is an excellent way to ensure you are staying in the optimal zone [1].

2. Prevention

Maintaining a healthy glucose ketone index (i.e. low to moderate ketosis) may be an effective tool for preventing many common metabolic diseases such as type 2 diabetes. Additionally, it may actually be very beneficial to periodically (once or twice per year) employ a metabolic therapy (such as an extended fasting period) that pushes our index into the 1.0-3.0 range as an effective technique for disease prevention.

3. Athletic performance
By measuring the glucose ketone index and correlating with diet, training regimen and performance, athletes may be able to identify their own personal zones of optimal performance.

4. Weight loss
For those using metabolic therapy to lose weight, the glucose ketone index may actually be a more effective marker than tracking glucose and ketones independently. Heads Up Health can help to track and correlate the index along with other metrics such as weight and body fat.

5. Fasting
Tracking the glucose ketone index can be a very helpful piece of biofeedback to understand how your metabolism is responding during the fasting period. Over time, you can look back at different fasting periods and use the index as an indicator of your metabolic state during the course of the fasting period.

6. Feeling awesome
If you are employing fasting and/or ketogenic diets for optimal health, the glucose ketone index can help you find your ideal sweet spot. If you reach a point where you start feeling absolutely awesome (which you inevitably will in ketosis), take a glucose and ketone reading and calculate your index. Having data to know when you are feeling your best will increase your chances of being able to consistently reproduce this state of optimal performance.

Here is a infographic created by one of our beloved Heads Up users, Michael Alward, based on Optimal Ketogenic Living’s Raymund Edwards’ work with Dr. Thomas Seyfried:

Tracking the Glucose Ketone Index in Heads Up Health

In order to track the glucose ketone index, you will need to measure glucose and ketones at the same time. This means two drops of blood - one for glucose and one for ketones.

Create a new Glucose Ketone Index reading by entering both numbers into your Heads Up profile. For those who measure blood glucose in mg/dL, Heads Up Health will convert this number into mmol/L as part of the calculation.
