In "Game Changers," Dave Asprey explores the fascinating world of biohacking - the practice of intentionally manipulating your biology to optimize your body and mind. Drawing from interviews with 450 highly successful individuals across various fields, Asprey presents a wealth of insights and practical strategies for upgrading your "operating system" to achieve peak performance in all areas of life.
The book is based on the premise that our bodies and minds are still running on outdated software, designed for the survival needs of our prehistoric ancestors. To thrive in the modern world and pursue higher-order goals, we need to update this operating system. Asprey introduces readers to the concept of biohacking as a means to take control of our automatic thoughts and behaviors, particularly those revolving around the "three Fs" - fear, food, and fornication.
Throughout the book, Asprey offers a blend of scientific understanding and actionable advice, making complex biological concepts accessible to the average reader. He covers a wide range of topics, from nutrition and sleep to exercise and emotional control, all with the aim of helping readers optimize their performance and achieve their goals.
As we delve into the key ideas of "Game Changers," we'll explore how to clarify our goals, prioritize our energy, overcome emotional eating, optimize our sleep patterns, exercise more effectively, manage our sexual energy, and conquer our fears. By the end of this summary, you'll have a comprehensive understanding of the principles of biohacking and how to apply them to your own life for dramatic improvements in your physical and mental performance.
Clarifying Your Goals
Before diving into the specifics of biohacking, Asprey emphasizes the importance of knowing what you're working towards. After all, optimizing your body and mind is pointless if you don't have a clear direction. He provides several strategies for identifying and clarifying your goals.
Identifying Your Passions
The first step in goal-setting is to identify your true passions. These are the activities that excite you just by thinking about them. Asprey gives the example of billionaire Naveen Jain, who is so passionate about science that he eagerly jumps out of bed after only four hours of sleep, excited to continue learning.
To help identify your passions, Asprey suggests a thought experiment: Imagine you're a billionaire with a fantastic family and a happy home life. All your basic needs and desires are taken care of. What would you do now? The answers to this question represent your true passions - the things you want to do for their own sake, not as a means to an end.
Distinguishing Between Means Goals and End Goals
Asprey introduces an important distinction between means goals and end goals. Means goals are things you want to achieve in order to reach something else. For example, someone might want to get married as a means of feeling intimately connected to another person.
End goals, on the other hand, are things you want to achieve for their own sake. These are the underlying reasons for your means goals. Asprey categorizes end goals into three types:
- Experiences: Such as waking up next to a loved one every morning.
- Growth: For example, developing leadership skills.
- Contribution: Like building a unique company that positively impacts others.
Understanding this distinction is crucial because people often become fixated on means goals (like making money) and lose sight of their end goals (like the experiences or contributions that money could enable). By keeping your end goals in mind, you can ensure that your daily actions are aligned with your true desires and aspirations.
The Importance of Remembering End Goals
Asprey stresses the importance of keeping your end goals in mind when planning your day. It's easy to get caught up in the pursuit of means goals and forget why you wanted them in the first place. By regularly reminding yourself of your end goals, you can stay motivated and ensure that your actions are truly serving your deeper aspirations.
For example, if your end goal is to contribute to the world by creating a business that helps people, you might find yourself getting bogged down in the day-to-day tasks of running the business. By regularly reminding yourself of your end goal - the positive impact you want to have - you can maintain your enthusiasm and make decisions that align with this larger purpose.
Prioritizing and Avoiding Decision Fatigue
Once you've clarified your goals, the next step is to prioritize your time and energy effectively. Asprey emphasizes that these are finite resources, much like the money in your bank account, and need to be guarded and deployed strategically.
Understanding Decision Fatigue
One of the biggest drains on our time and energy is decision fatigue. This phenomenon occurs because making decisions is hard work. It requires brain power to weigh options and willpower to commit to a choice. Asprey likens willpower to a muscle that gets worn out with use.
By the end of each day, we've made countless decisions, from small ones like what socks to wear to larger ones like how to handle a difficult work situation. While no single decision may be overwhelming, the cumulative effect leaves us exhausted as the day progresses.
Strategies to Minimize Decision Fatigue
To combat decision fatigue, Asprey suggests minimizing the number of decisions you have to make each day, especially those that aren't directly relevant to your end goals. Here are some strategies he recommends:
Automate daily tasks: Create systems that reduce the number of decisions you need to make. For example, you could create a capsule wardrobe with a limited number of interchangeable items, eliminating the need to decide what to wear each morning.
Follow Steve Jobs' example: Jobs famously wore the same black turtleneck and jeans every day, completely eliminating clothing decisions from his life.
Create a capsule diet: Develop a rotation of 5-6 healthy meals that you cycle through. This reduces the mental energy spent on meal planning while ensuring you eat nutritiously.
By automating these everyday tasks, you free up mental energy and willpower for the decisions that truly matter - those related to your higher goals in life.
Prioritizing Your Most Important Work
With the mental space created by reducing decision fatigue, you can now prioritize your most important work. Asprey encourages readers to reserve their most precious internal resources - time, energy, and willpower - for their most significant tasks and goals.
This might mean tackling your most challenging work when your energy is highest, whether that's first thing in the morning or later in the day, depending on your natural rhythms. It could also involve scheduling your most creative or strategic thinking for times when you're least likely to be interrupted.
By consciously allocating your resources in this way, you ensure that you're making progress on what truly matters, rather than squandering your energy on trivial decisions and tasks.
Overcoming Emotional Eating
Having addressed goal-setting and prioritization, Asprey turns his attention to one of the three Fs: food. He emphasizes that while food provides the energy our bodies need to function, our modern approach to eating is often out of sync with our biological needs.
Understanding Emotional Eating
Asprey points out that many of us experience a sense of lack in various areas of our lives - lack of energy, sleep, love, connection, or security. Instead of addressing these lacks directly, we often try to fill them with food.
This leads to emotional eating - the habit of seeking out food when we're feeling sad, stressed, angry, bored, or even joyful. Asprey argues that what we interpret as hunger is often just a sense of emptiness stemming from these deeper lacks.
The Problem with Emotional Eating
Emotional eating disrupts our body's natural hunger signals. Instead of acting as an accurate internal barometer of our body's need for food, our sense of hunger goes haywire. This is particularly problematic in today's world, where we're surrounded by readily available junk food and unhealthy attitudes towards eating, such as large portion sizes and constant snacking.
Identifying Emotional Eating Triggers
To regain control over your diet, Asprey suggests starting by identifying the false hunger signals you're receiving. He recommends asking yourself questions when you feel hungry:
- Am I actually hungry, or am I feeling bored, stressed, lonely, or experiencing some other emotion?
- Is it just a coincidence that I feel hungry right after someone upset me?
He also points out some telltale signs of emotional eating:
- Sudden flares of hunger
- Cravings for specific foods
- Persistent feelings of hunger even after eating
However, Asprey cautions that these signs can also indicate problems with your diet, such as consuming too much trans fat or too little protein.
Eating Like Your Grandma
To recalibrate both your diet and your hunger signals, Asprey offers a simple rule of thumb: eat like your grandma (assuming she was alive before World War II). He argues that people of that generation likely ate a much healthier diet than we do now, as they lived before the rise of the modern food industry.
This "grandma diet" typically included:
- Lots of vegetables
- Plenty of protein-rich foods
- A daily tablespoon of fish oil
This combination provided the body with:
- Polyphenol compounds for cellular energy
- Amino acids and proteins for muscle building
- Omega-3 fatty acids for anti-inflammatory hormones
Importantly, this diet was characterized by moderate and infrequent eating. Asprey suggests that if you're eating the right kinds of food, you should be able to eat a small meal and go five hours without feeling hungry again.
Optimizing Sleep
After addressing diet, Asprey moves on to another crucial aspect of physical wellbeing: sleep. He notes that getting a good night's sleep was the fifth most common performance-enhancing habit among the high achievers he interviewed.
Understanding Chronotypes
The key to biohacking your sleep, according to Asprey, is to identify your natural sleep pattern and adjust your schedule accordingly. This pattern is determined by your body's circadian rhythm, which acts as an internal clock. Asprey introduces four types of circadian rhythms, or chronotypes:
- Lions: Early risers who are full of energy in the morning but tire in the evening.
- Wolves: Night owls who naturally wake up later and have two energy peaks - one from noon to 2 PM and another after sunset.
- Bears: Those whose sleep patterns naturally follow the rise and fall of the sun.
- Dolphins: Prone to insomnia and tend to perform best from mid-morning to early afternoon.
Embracing Your Chronotype
Asprey emphasizes that your chronotype is genetically determined, so trying to fight against it is counterproductive. He shares his personal experience of trying to force himself to be a "lion" when he's naturally a "wolf." This attempt to conform to society's notion of success (the "early bird gets the worm" mentality) left him with a foggy mind and decreased creativity.
When he finally adjusted his sleep schedule to align with his natural wolf-style circadian rhythm, he found himself happier and more productive.
Identifying Your Chronotype
To discover your chronotype, Asprey suggests using a vacation week to conduct an experiment. Allow yourself to go to bed and wake up when your body naturally feels like it. The pattern you gravitate towards is likely your chronotype.
Adjusting Your Sleep Schedule
Once you've identified your chronotype, Asprey recommends adapting your sleep schedule accordingly. This might mean:
- For Lions: Going to bed early and waking up at dawn
- For Wolves: Having a later bedtime and wake-up time
- For Bears: Following a more traditional sleep schedule aligned with daylight hours
- For Dolphins: Finding a sleep routine that minimizes insomnia, possibly with an earlier bedtime
By aligning your sleep schedule with your natural rhythms, you can improve the quality of your sleep, boost your alertness, and enhance your overall productivity and performance.
Exercising Effectively
While diet and sleep are crucial, Asprey also addresses the importance of physical movement. He points out that our bodies were designed to move, but modern sedentary lifestyles often leave us stationary for long periods, leading to issues like stiff muscles and back pain.
The Pitfalls of Conventional Exercise
However, Asprey cautions that simply adding exercise to a sedentary lifestyle isn't a complete solution. He highlights several problems with conventional approaches to exercise:
The Sedentary Athlete Problem: If you exercise for an hour but sit for the rest of the day, you're essentially a sedentary person who does intense movements occasionally. Asprey notes that six hours of sitting can negate the benefits of a one-hour workout.
Risk of Injury: High-risk sports, including popular forms of exercise like running, can put our bodies at risk of injury. This is especially true for those who haven't mastered proper motor control and range of movement due to sedentary lifestyles.
Oxidative Stress: Aerobic exercise leads to the production of the stress hormone cortisol, which triggers the creation of oxidative substances that accelerate aging and cause inflammation.
Solutions for Effective Exercise
To counteract these issues, Asprey offers several solutions:
Reduce Sitting Time: Invest in a standing desk to avoid long periods of sitting.
Learn Proper Movement: Consider working with a functional movement coach to learn how to move your body correctly and safely.
Balance Aerobic and Strength Training: Add strength training to your workout routine to produce anabolic hormones that combat oxidation.
Supplement Wisely: Use antioxidants and probiotics to further counteract the aging effects of oxidation from aerobic exercise.
By implementing these strategies, you can ensure that your exercise routine is truly benefiting your body rather than potentially causing harm.
Managing Sexual Energy
Asprey then turns to the third F: fornication, or more broadly, sexual energy. He argues that sex, while obviously important for the continuation of the species, can be a significant drain on our energy if not managed properly.
The Energy Cost of Sex
Asprey points out that we often expend a lot of energy on sex, both physically and mentally. Even when we're not actively engaged in sexual activity, we may be thinking about it or investing energy in improving our physical appearance for the sake of sexual attractiveness.
While this makes sense from an evolutionary standpoint, Asprey argues that it can be problematic from an individual perspective for two reasons:
Energy Allocation: The more energy we allocate to sex, the less we have for other aspects of our lives.
Biochemical Effects: Particularly for men, the biochemical effects of sex can be energy-draining. After ejaculation, men produce the hormone prolactin, which causes sleepiness and counteracts dopamine, potentially leading to feelings of tiredness and even depression.
Gender Differences in Sexual Biochemistry
Asprey notes that the biochemical effects of sex differ between men and women:
- Men: Experience higher prolactin production after orgasm, leading to tiredness and potential mood drops.
- Women: Produce less prolactin and experience more positive biochemical effects, including reduced cortisol (stress hormone) production and increased serotonin, oxytocin, and estrogen.
Recommendations for Managing Sexual Energy
Based on these differences, Asprey makes the following recommendations:
For Men: Limit orgasms to once per week to preserve energy and maintain higher levels of motivation and drive.
For Women: Aim for at least two orgasms per week to benefit from the positive hormonal effects.
Energy Sublimation: Consider channeling sexual energy into creative projects or other higher pursuits. Asprey cites examples of athletes and even entire sports teams abstaining from sex before competitions to preserve energy and focus.
Asprey shares anecdotes from listeners of his podcast who followed this advice and reported significant benefits, including increased energy for pursuing long-held dreams and even substantial salary increases.
Overcoming Fear
The final F that Asprey addresses is fear. He explains that due to our evolutionary history, our subconscious is programmed to keep us in a state of alertness rather than allowing us to feel completely safe.
The Problem with Persistent Fear
While fear was a useful emotion for our prehistoric ancestors facing constant threats, it's often counterproductive in our relatively safe modern world. Asprey outlines several ways that persistent fear can hinder our success and happiness:
Energy Drain: Fear triggers stress, which depletes our energy and can lead to burnout.
Present-Moment Disconnection: Fear typically focuses on potential future negative events, taking us out of the present moment where we could be taking productive action.
Risk Aversion: Fear discourages us from taking the risks often necessary for success, as we're hardwired to be strongly averse to failure due to its potentially fatal consequences in prehistoric times.
The Limitations of Courage
While courage can help us overcome fear, Asprey points out that it's not a complete solution. Courage requires energy, and we only have so much energy to expend. This means that relying solely on courage to combat fear is not a sustainable long-term strategy.
Strategies for Overcoming Fear
To address these issues, Asprey introduces the concept of safety cues - signals that tell our subconscious that it's safe to relax. He offers several strategies for creating these cues:
Soothing Sounds: Listen to calming voices or peaceful music. This can include guided meditations, which have the added benefit of bringing your mind back to the present moment.
Visualization: Create a detailed mental image of a safe, peaceful setting where you feel completely at ease. Engage all your senses in this visualization to make it as vivid as possible.
Gratitude Practice: Cultivate a habit of feeling grateful for various aspects of your life, including your failures (reframed as learning experiences). This signals to your subconscious that things are going well.
Asprey recommends keeping a gratitude journal, writing down three things you're grateful for each morning and/or evening. He cites entrepreneur UJ Ramdas, co-creator of the Five Minute Journal app, who claims that this practice can improve sleep quality, strengthen relationships, and increase kindness towards others.
