• Momentous supplements are generally in single ingredient formulations.
• Using single ingredient formulations can help devise the most logical and effective supplementation regimen.
• Momentous supplements are shipped internationally, making them accessible to listeners outside the United States.

Levels and Continuous Glucose Monitoring

• Levels is a program that lets you see how different foods and activities affect your health by giving you real-time feedback on your blood glucose using a continuous glucose monitor.
• Blood glucose level is critical for everything from fat loss to muscle gain to healthy cognition and aging of the brain and body.
• Most people do not know how different foods and activities impact their blood glucose level.
• Using levels has taught the speaker when best to eat, what best to eat, when best to exercise, and how to modulate their entire schedule.

Element and Electrolyte Drink

• Element is an electrolyte drink that contains the exact ratios of the electrolyte sodium, magnesium, and potassium to optimize cellular functioning for mental and physical performance.
• Hydration is key for optimal performance, but the correct ratios of sodium, magnesium, and potassium are also important.
• People with pre-hypertension and hypertension need to be careful about their sodium intake, but everyone needs to pay attention to their electrolyte intake.
• Drinking caffeine, exercising, and following a clean diet can all impact electrolyte levels.

Section 1: Importance of Hydration

• Hydration is a fundamental aspect of nutrition and supplementation for performance and health.
• The body needs to maintain a balance of sodium, potassium, and magnesium to optimize mental and physical performance.
• Drinking water and electrolytes is important for maintaining hydration and supporting performance.
• The body's urine should be relatively clear, with a dark yellow color indicating dehydration.
• Alkaline water may not change the body's alkalinity, and its benefits are not well-established.

Section 2: Electrolytes and Hydration

• Electrolytes, including sodium, magnesium, and potassium, are important for maintaining hydration and supporting performance.
• Electrolytes can be obtained through food and supplements, but water and electrolytes are the most important source.
• The body's ability to maintain electrolyte balance is crucial for preventing seizures, vomiting, and even death.
• The alkalinity of the body is well-controlled to maintain a healthy state, and changing it with alkaline water may not be beneficial.
• It is important to focus on hydration and electrolyte balance before worrying about the pH of drinking fluids.

Section 3: Volume of Water and Hydration

• The body needs a certain volume of water to maintain hydration and support performance.
• The amount of water needed depends on factors such as age, gender, weight, and activity level.
• Drinking water before, during, and after exercise can help maintain hydration and improve performance.
• Dehydration can negatively affect physical and mental performance, even at a low level of dehydration.
• Maintaining proper hydration can improve accuracy, endurance, and speed in various activities.

Section 4: Hormesis and Hydration

• Hormesis is a phenomenon where a low dose of a substance can have a beneficial effect on the body.
• Dehydration is an example of hormesis, as it can have negative effects on the body at low levels and improve performance when hydration is restored.
• Being dehydrated can reduce blood volume, making it harder for the body to pump blood and leading to endurance issues.
• Maintaining proper hydration can improve accuracy, endurance, and speed in various activities.
• It is important to start a program hydrated to avoid negative effects of dehydration on performance.

The Importance of Hydration

• Hydration is crucial for optimal performance and recovery.
• Sodium, potassium, and chloride are electrolytes that are essential for muscle contraction and nerve function.
• The concentration of these electrolytes inside and outside the cell must be balanced for proper function.
• Drinking too much water can dilute the concentration of these electrolytes, leading to problems such as hyponatremia.
• Hyponatremia can be life-threatening and can cause symptoms such as brain fog, confusion, and GI distress.

The Dangers of Excessive Fluid Intake

• Excessive fluid intake can lead to dilution of electrolytes and an imbalance in concentration.
• Drinking too much water can also cause hyponatremia, which can be life-threatening.
• It is important to pay attention to hydration levels and not just rely on the "middle" approach.

The Role of Electrolytes in Muscle Contraction

• Sodium, potassium, and chloride are electrolytes that are essential for muscle contraction and nerve function.
• These electrolytes must be balanced inside and outside the cell for proper function.
• Drinking too much water can dilute the concentration of these electrolytes, leading to problems such as hyponatremia.

The Importance of Precision Supplementation

• Supplements can provide potent compounds that can transform our ability to perform in the short term and recover from exercise.
• It is important to focus on basic sleep, nutrition, hydration, and other factors for optimal performance.
• Precision supplementation is necessary to give individuals exactly what they need.

• Adrenal fatigue and other conditions may be misdiagnosed without proper hydration and electrolyte balance.
• Hydration and electrolyte balance are the foundation for optimal performance and recovery.

Hydration

• Drinking water is important for hydration.
• The general rule is to drink half an ounce of water per pound of body weight.
• Exercise and sweating can increase water loss, so it's important to drink more water back after exercise.
• The amount of water lost during exercise can vary depending on factors such as exercise intensity and environment.
• Weighing oneself naked before and after a workout can help determine the amount of water lost.

Supplements

• Supplements can provide additional nutrients and support for optimal performance.
• It's important to focus on basic nutrition, hydration, and other factors for optimal performance.
• Precision supplementation is important to ensure individuals are getting exactly what they need.
• The 80/20 rule applies to supplements, where 80% of the benefit can be achieved with the lowest cost.

Sleep

• Getting enough sleep is important for overall health and performance.
• Sleep can affect hormones, recovery, and overall well-being.
• It's important to prioritize sleep and aim for 7-9 hours per night.

Nutrition

• Eating a balanced diet is important for optimal health and performance.
• Carbohydrates, protein, and healthy fats are all important for energy and recovery.
• It's important to pay attention to portion sizes and calorie intake for optimal performance.

Hydration Diagnosis

• Diagnosing hydration levels can be done through various methods such as urine color and weight.
• Urine color can indicate dehydration, with darker urine indicating a need for more water.
• Weighing oneself naked before and after a workout can help determine the amount of water lost.

Caffeine and Dehydration

• Caffeine can enhance dehydration, but coffee does not necessarily do that because it is co-ingested with fluid.
• Caffeine has a diuretic effect, which can lead to yearning and how much.
• The ergogenic effects and benefits of caffeine outweigh the concern about caffeine's diuretic effect.
• The amount of sodium lost to caffeine is not as important as the amount of sodium being correct.
• Sweating ability, or the individual's ability to sweat, is important for heat acclimation and performance.

Sweating Ability

• Sweating ability varies among individuals and is important for heat acclimation and performance.
• Some individuals have a robust sweating adaptation, while others do not.
• Sweating ability is not something that can be easily binned into low, medium, or heavy sweater categories.
• Sweating ability is not what regulates temperature, but rather the fluid hitting the skin and evaporating off the body.
• If an individual is not sweating enough, they are limiting their output capacity and performance.

Sweating and Heat Acclimation

• Heat acclimation training involves practicing sweating and allowing the body to get used to sweating.
• Sweating ability can be improved through practice and heat acclimation training.
• Sweating ability is important for heat acclimation and performance.
• Sweating ability is not just about having enough fluid to switch wet, but also being able to sweat and being dressed appropriately to allow that sweat to move and evaporate off the body.
• Genetics play a huge role in sweating ability, with some individuals having a genetic component that allows them to sweat more or less than others.

Identifying Salt Sweaters

• Salt sweaters can be identified by looking at their clothing and seeing white residue all over it.
• If the white junk is covering the clothing, the individual is a higher salt sweater.
• If the opposite happens and it's like you can pull their clothing back and there's just nothing there, they are maybe a little bit of a lower salt sweater.
• Hydration tests can also be used to estimate the amount of salt sweat, but their accuracy is not yet proven.
• There are a number of cheap patches available that can give a reasonably close estimate of the amount of salt sweat.

Matching Electrolyte Intake

• It is important to match electrolyte intake to something close to what is sweated out.
• Acute markers of dehydration like hemoglobin and hematocrit can be used to determine hydration status.
• Blood chemistry tests can also provide insights into sodium and potassium levels.
• Measuring body weight pre and post exercise and using a sweat patch can give a rough idea of where the individual is getting their salt from.
• Equations can be used to determine how much water to drink during training, but this is not critical for individuals who are not losing more than two percent of their body weight during exercise.

Optimizing Hydration

• A three-step system for optimizing hydration can be followed.
• It is important to note that people should not be overly concerned about hydrating if they are performing a type of training or exercise in which they are not losing more than two percent of their body weight.
• The amount of water to drink during training can be determined using equations.
• If an individual is losing less than two percent of their body weight during exercise, fluids can make them feel better but it is not critical to their performance or recovery.
• Athletic Greens is a vitamin, mineral, probiotic, and adaptogen drink designed to meet all of an individual's foundational nutritional needs.

The Galpin Equation

• The Galpin equation is a formula for determining how much fluid to ingest during exercise.
• To calculate the Galpin equation, divide your body weight in pounds by 30 and consume that number of ounces of water every 15 to 20 minutes.
• The Galpin equation can be used in the metric system by dividing your body weight in kilograms by 30 and consuming that number of milliliters of water every 15 to 20 minutes.
• People should ingest fluid consistently, either every 15 minutes or by "slugging it back."
• Slower and steady hydration is generally better for performance.

Hydration and Recovery

• Continuous glucose, amino acid, and hydration streams are necessary for recovery.
• GI distress should be offset during recovery.
• The four golden rules of recovery are rebuild, rehydrate, replenish, and don't disturb the gut too much.
• The Galpin equation can help optimize performance by providing a rough idea of how much fluid to consume.
• The final net number of fluid lost during training should be added back to the original amount consumed.

Fluid Intake and Weight Loss

• Fluid intake during exercise can influence weight loss.
• The Galpin equation can be used to determine how much fluid to consume during training.
• The final net number of fluid lost during training should be added back to the original amount consumed.
• Papers suggest that fluid intake during exercise can be up to 150% of the original amount consumed.
• It's important to consume fluids consistently during training to optimize performance.

Hydration

• Drinking water first thing in the morning helps kickstart the day and saves time from drinking water at night.
• Drinking water throughout the day is important to maintain hydration.
• Drinking water before going to sleep can help with sleep quality.
• Drinking water in the final hour before sleep can help with sleep quality.
• Drinking water in the three hours before sleep can help with sleep quality.

Supplementation and Nutrition

• Supplementation and nutrition are important for optimal performance.
• Supplements are potent compounds that can transform our ability to perform in the short term and recover from exercise.

• Starting the day hydrated is important for performance enhancement and not compromising sleep.
• Consuming fluids closer to hydration is important for optimal performance.
• Eating mostly real whole foods is important for hydration status.
• Water throwing watermelons is not necessarily bad, but for most people they are ingesting too much sugar.

Section 2: Choosing the Right Foods

• Food choices determine hydration status.
• Watermelon is a great source of hydration and is not extremely high in carbohydrate or sugar.
• People who are justifying the ingestion of sugar should not ingest too much sugar.
• Eating whole real food is important for hydration status.
• Meat is a high percentage of fluid, but not as high as something like a biscuit.

Section 3: Morning Hydration

• Morning hydration is important for performance.
• Meat is a good source of hydration, but not as high as something like a biscuit.
• Eating highly processed foods can lead to dehydration and high salt intake.
• Adding salt back is important for optimal hydration.
• Pre-hydrating before a workout session is important.

Section 4: Hydration Metrics

• Checking body weight, urine color, and engaging thirst can predict actual hydration status.
• Using weight urine and thirst as metrics can significantly predict actual hydration status.
• The number of milliliters of water in the hour proceeding the training is a good indicator of hydration status.
• The number of milliliters of water in the hour proceeding the training is typically told to be between 400 to 500 milliliters.
• Drinking water soon after exercise is important for people who are going to give a talk or don't want to have to get up to use the restroom.

Hydration Before Exercise

• Drinking water before exercise is important to prevent dehydration.
• The recommended amount of water to drink before exercise is 15-20 minutes before, with 1-3 liters of water consumed in total.
• Drinking too much water before exercise can cause stomach discomfort and bloating.
• It is important to consume fluids that are iso-osmotic to your blood, meaning they have the same concentration as your blood.
• Electrolyte products are often recommended for intra-workout hydration, with a concentration of 200-400 milligrams of sodium and other electrolytes.

Sweat and Hydration

• Sweat is a natural way for the body to cool down and regulate body temperature.
• Sweat is made up of water, electrolytes, and other substances.
• The body loses electrolytes, particularly sodium, when it sweats.
• It is important to replace these electrolytes to maintain proper hydration and prevent dehydration.
• Drinking fluids that are iso-osmotic to your blood can help to replenish lost electrolytes and maintain proper hydration.

Sodium Intake

• Sodium is an important electrolyte that helps to regulate blood pressure and maintain proper hydration.
• Many processed foods contain high levels of sodium, which can lead to high blood pressure and other health problems.
• It is important to limit sodium intake for people with pre-hypertension or hypertension.
• Many people do not get enough sodium in their diets, which can lead to mental clarity, focus, and physical stamina problems.
• It is important to consume a variety of foods to get enough sodium, including non-processed or minimally processed foods.

Caffeine and Hydration

• Caffeine can help to increase alertness and mental clarity.
• Caffeine can also help to improve physical performance by increasing adrenaline levels.
• Caffeine can cause dehydration, particularly when consumed in large amounts or in hot environments.
• It is important to drink plenty of water when consuming caffeine to prevent dehydration.
• Combining caffeine with other hydration-enhancing substances, such as electrolyte drinks, can help to improve hydration and performance.

Supplements and Hydration

• Supplements can help to improve hydration by providing additional electrolytes and other nutrients.
• Element is a popular supplement that can help to improve hydration and performance by providing additional sodium and other electrolytes.
• Other supplements, such as pink salt or Himalayan salt, can also help to improve hydration by providing additional sodium and other electrolytes.
• It is important to measure blood pressure and other health markers to determine if supplements are necessary.
• It is important to work with a medical specialist before taking any supplements to ensure safety and effectiveness.

Supplementation for Enhanced Training

• Supplementation can enhance training by taking certain things before training.
• The recommended sodium to potassium ratio is roughly three to one.
• There are different electrolyte companies to choose from, depending on the situation.
• Carbohydrates can enhance performance in certain situations, such as long duration or high-intensity training.
• Sports drinks can be undersalted and may not provide enough sodium.

Carbohydrates for Enhanced Performance

• Carbohydrates can enhance performance during exercise.
• The recommended carbohydrate intake per hour is 60-100 grams.
• The Galloping equation recommends splitting the carbohydrate intake into 15-minute intervals.
• The type of carbohydrate matters, with glucose and fructose being the most effective.
• Resistant starches can be used for long bouts of exercise, while glucose and fructose are more effective during the middle of the workout.

Fuel Product for Enhanced Training

• Fuel products can enhance training by providing a specific combination of glucose and fructose.
• Fuel products can be used in combination with other easily absorbable and usable foods.
• Honey and other easily absorbable and usable foods can be used to enhance carbohydrate intake.
• Fuel products can be used to maximize total carbohydrate intake during exercise.
• Fuel products can be used to drive water into the cell and enhance hydration during exercise.

Drink to Get Away with

• Drinking a combination of 5-9% glucose for optimal performance.
• Training the gut to digest carbohydrates.
• Avoiding anything new in competition.
• Trying different food items and amounts.
• Monitoring carbohydrate, sodium, and water intake.

Personalized Nutrition Platform

• Tracker analyzes data from blood and DNA to help individuals understand their body and reach their health goals.
• Knowing what to do with the information from blood tests is easy with Tracker.
• Tracker provides personalized recommendations on behavioral changes, nutritional changes, and supplementation.
• Tracker helps individuals bring their levels into the optimal ranges for their health.

Supplementation for Workouts

• Ingesting nothing before a workout can be beneficial.
• Drinking water and caffeine before weight training workouts.
• Delaying caffeine intake 90-120 minutes after waking.
• Training fasted can improve performance and recovery.

Training Fasted

• Ingesting carbohydrates the night before to top off glycogen stores.
• Training fasted can improve performance and recovery.
• Some people may opt to not eat anything in the two to four hours prior to training.
• Caffeine can hit the system better when ingested fasted.

Fueling Before Exercise

• The amount of energy expenditure in different sports is related to the hours needed for sleep.
• Fueling is necessary for exercise that requires a lot of energy expenditure.
• Fueling is not necessary for exercise that does not require a lot of energy expenditure.
• Examples of exercise that require a lot of energy expenditure include maximal exertion and golf practice.
• In these cases, it is important to keep blood glucose fairly even and avoid stimulants.

Macronutrients

• The total amount of macronutrients throughout the day is more important than the timing of them.
• Carbohydrates can be consumed at night and not eaten the next morning and still be fine.
• Muscle glycogen is topped off after a few hours, so it is not necessary to consume carbohydrates immediately before a workout.
• Athletes prefer to do many of their training sessions faster in the morning for personal reasons, not because it enhances performance.
• Recovery starts during the previous workout, and it is important to consume nutrients to optimize recovery.

Carbohydrates and Protein

• The total amount of protein ingested throughout the day is a bigger determinant for things like muscle growth than the timing.
• Carbohydrate is different from protein, and the timing of carbohydrate matters for muscle glycogen resynthesis.
• In cases where an athlete trains multiple times a day, a recovery window is half what they normally have.
• If an athlete is in a situation where they have two or three days before they work out again, they do not need to worry about getting carbohydrate in before, during, or after the workout.
• The general rule of thumb is to consume about half a gram of carbohydrate per pound of body weight.

Protein

• Protein is about half of the total amount of macronutrients needed for muscle growth.
• The amount of protein needed depends on the energy expenditure and potential muscle damage or energy utilization.
• If an athlete is doing a hard workout, they should consume about half a gram of carbohydrate per pound of body weight.
• The amount of carbohydrate needed depends on the energy expenditure and potential muscle damage or energy utilization.
• If an athlete is doing a lower energy and easier workout, they can consume less carbohydrate.

Section 1: Caffeine as a Stimulant

• Caffeine is a potent compound that can transform our ability to perform in the short term and recover from exercise.
• It has a negrogenic effect, meaning it can take it at whatever dosage is reasonable for you.
• The half-life of caffeine is about 4 to 6 hours, but it can vary depending on the person.
• Caffeine can have an ergogenic benefit, even though if it doesn't feel a big boost to some people.
• Caffeine can have a noticeable effect on endurance and maximum strength, but the effects on peak strength are mixed.

Section 2: Dosage and Timing of Caffeine

• One to three milligrams per kilogram of body weight is the recommended dosage of caffeine.
• It should be taken about 30 minutes prior to exercise to have a performance-enhancing effect.
• Caffeine can also have a mental performance-enhancing effect, especially when people who are regular caffeine users have abstained from caffeine for a while.
• If people are not caffeine adapted, the sudden introduction of caffeine can degrade performance.
• The amount of caffeine in different sources varies, and the smallest commercially available coffees contain anywhere from 250 to 350 milligrams of caffeine.

Section 3: Caffeine and Performance

• Caffeine can enhance reaction time, power output, and endurance.
• It can also have a noticeable effect on reaction time and power output.
• Caffeine can degrade performance if people are not caffeine adapted.
• If people take too much caffeine, it can ruin their sleep.
• Most people listening to this should go for their quad espresso shot before their every time they go to work out.

Section 4: Caffeine and Adaptation

• Caffeine can be taken at whatever dosage is reasonable for you.
• The more you take caffeine, the more you need to take even though there's actually some recent evidence showing even folks who are acclimated to it will still see an ergogenic benefit.
• Some people can smell coffee and immediately feel better, but this is probably working through a different mechanism than the caffeine itself.
• Caffeine can have a mental performance-enhancing effect, especially when people who are regular caffeine users have abstained from caffeine for a while.
• If people are not caffeine adapted, the sudden introduction of caffeine can degrade performance.
