What I learned tracking nutrition and fitness data with Function Health

Optimizing your health to live 100 healthy years

I’ve always been incredibly passionate about optimizing my health through lifestyle changes, such as nutrition and fitness. I like to think of general health and well-being as something that can be divided into two parts: things in my control and things out of my control. Though I can’t control certain portions of my health, such as genetics and family history, I (and you) can control my daily habits.

Often, people underestimate just how powerful changes to your nutrition and exercise habits can be to support your health. These things matter more than you’d think, and Function Health is here to help you see why. This new longevity platform, designed to empower everyone to live 100 healthy years, can help you optimize your daily health habits and support a healthier, longer life. Here’s what I thought about this innovative new health program.

Why data collected by Function Health matters

Data is essential to improving your health and fitness. With this in mind, the Function Health process begins with an initial set of lab tests (broken into two separate visits) that include over 100+ blood lab tests. Each of these blood tests provides insight into some component of your health, such as testing nutrient or electrolyte levels in your blood. By collecting this data, doctors can examine which areas of your health could use additional support to help you feel and perform your best (and live as long as possible).

Electrolytes

For example, the Function Health lab panel includes testing for six essential electrolytes: magnesium, sodium, chloride, carbon dioxide, potassium, and calcium. In the short term, understanding where your electrolyte levels fall can help you adjust your food and supplement intake to enhance your athletic performance and improve your daily feelings. Electrolyte levels are critical in supporting muscle function. Therefore, maintaining optimal electrolytes can help you crush your workouts and support your body in recovery.

In the long term, this data can help you adapt your long-term habits and learn to select foods that help your body get all the electrolytes needed to thrive. Without lab testing, many of us wouldn’t know where our electrolyte levels fall (at least not until symptoms of a deficiency were severe).

Nutrients

Nutrient testing is another key component of the Function Health lab testing. The blood panel checks levels of essential vitamins in your body, such as zinc and omega 3. Function Health says, “Just as plants need nutritious soil and fertilizer to develop, humans need nutrients for survival, growth, and reproduction. Nutrients give us energy, fuel our hearts and minds, strengthen our immunity, and promote vitality. Imagine a garden that is well taken care of: properly watered, cared for, and fertilized. Now, imagine one that doesn’t have the safekeeping of a good gardener. Someone who feeds their garden with poor soil and drenches the plants with processed, unnatural nutrients will see that, slowly (or quickly), that garden will fall into disrepair. It is the same thing for the body.”

After reading this description, it’s easy to understand why tracking nutrient levels in the blood is helpful. Testing biomarkers such as vitamin D or omega 6 levels can change your health choices. For example, my Function Health lab testing showed my omega 6: Linoleic acid levels were too high.

Now, you’re probably thinking, “What does this mean?” Function Health doesn’t expect that we know exactly what this means. The detailed descriptions underneath each portion of your lab testing explain what each test means and its importance. In this case, I learned that my linoleic acid levels were higher than they should be for optimal health. This data reminds me to be more mindful of the seed-based oils I consume (often found when dining out), such as soybean oil, and to look for options with healthier cooking oils, such as olive oil.

Owning your own health

Function Health’s motto, encouraging users to “own their health,” fits precisely what I got from using this platform. After reviewing your lab results, the doctors on the team will create a personalized clinical summary with recommendations for starting to take control of your health. My “action plan” results provided a list of healthy foods I should try to incorporate into my diet and foods I should limit.

The action plan also provided five supplement recommendations based on my results. Of course, making these changes takes time, and Function Health recognizes it. For that reason, a retesting portion of the lab work is included in the platform fee so you can check in on how your habit changes and adjustments have improved your nutrient and electrolyte levels.

Overall, I feel this platform has exceptional value for anyone who wants to find more ways to make healthier choices, whether they’re looking to improve their cardiovascular fitness or want to make healthier choices generally to live a long and happy life. Knowledge is power, and this platform gives you insight into what’s going on inside your body. Remember that health tools like Function Health should be used in conjunction with advice from your doctor or healthcare professional.

This butter alternative can elevate your cooking and improve your health
4th &Heart Ghee

As ghee originated in ancient India thousands of years ago, you might encounter ghee today in Indian cooking, often paired with bread like naan or roti. Today, kitchens worldwide use ghee as a substitute for butter, perfect for cooking and baking due to its rich, buttery flavor and high smoking point. But what exactly is ghee, and should you swap it out for butter in your recipes? To learn more about the benefits of ghee, I spoke with Max Dichter, CEO of 4th & Heart, a California-based company specializing in innovative, high-quality ghee products.

Dichter has been with 4th & Heart since 2018. He has since raised capital, built a highly experienced leadership team, scaled its self-manufacturing capabilities, and drove 4th & Heart to its #1 leadership position in the ghee market. Since he joined the company seven years ago, it's safe to say Dichter has learned a thing (or two) about ghee. We discussed all things "ghee," and he shared some helpful insight into the excellent benefits of ghee. Here's what he wants people to know about using ghee in cooking.

When you work on your functional fitness, you augment your ability to perform everyday tasks and activities. For example, you’ll improve your ability to do things like getting up off the floor, reaching up to put something on a shelf, or carrying a heavy object. Research reveals that functional training can lower your risk of injury and improve your muscle strength, balance, mobility, quality of life, and general wellness. Inspiring fitness gurus are still recommending working on your functional fitness due to the many benefits and practical applications. Let’s look at the best exercises to try.

Functional fitness involves exercises that mimic the movements of daily activities and help you enhance your strength in those particular muscles. You’ll be less likely to pull or strain something throughout the day if you work on strengthening and stretching those muscles you use so often.
