Feeling a bit "off" lately? It's more common than you might think. Many people experience periods of low mood, fatigue, and general anxiety—a state often referred to as being in a 'funk', in fact, I myself have been in a funk this week wandering what the hell is going on. While we all have our off days, consistent feelings of unease can be disconcerting and disruptive. In this blog, I will dive into five reasons why you might be feeling low and edgy and offer scientifically proven insights to help you understand these experiences.

1. Mineral Imbalance: The Spark Plug of the Body

Think of your body as a well-tuned machine, requiring different 'spark plugs' or minerals, to run optimally. Sodium, potassium, magnesium, and calcium play a vital role in maintaining nerve impulse conduction, muscle function, and overall body fluid balance.

When we overdo it on activities such as fasting, intense training, or using infra-red saunas, we can lose vital minerals through sweat, which can lead to an imbalance. This imbalance might lead to anxiety, fatigue, low blood pressure, and consequently, low mood. Picture it as a see-saw; when one side is heavily weighed down (too much mineral loss), the other side lifts off (mood and energy plummet).

Magnesium is a crucial mineral for our body and plays an integral role in nerve function. It helps regulate neurotransmitters, which are chemical messengers that transmit signals throughout the nervous system. Neurotransmitters help control everything from our heartbeat to our ability to concentrate. Magnesium acts like the conductor of this intricate symphony, facilitating these vital communications and promoting a balanced, relaxed state in the nervous system.

When we're low on magnesium, it's like the orchestra loses its conductor. This can lead to hyper-excitability of the nervous system, manifesting as anxiety, restlessness, and difficulty sleeping. Think of an orchestra trying to perform without a conductor—there would be a lot of noise, but not much harmony.

Sodium is like the first violinist; it leads the other instruments, particularly in maintaining fluid balance, conducting nerve impulses, and influencing muscle function.

Under stress, our body's response is much like a band playing a faster, more intense tune. In physiological terms, the adrenal glands release the stress hormone cortisol, leading to an increased excretion of sodium through the kidneys. If sodium levels get too low (a condition known as hyponatremia), it can lead to symptoms such as brain fog, confusion, irritability, and fatigue. It's as if the lead violinist suddenly went off-key, leaving the rest of the orchestra in a state of discord.

In particular, low-carb diets can lead to a state known as "keto-flu," with symptoms remarkably similar to sodium deficiency. This is because insulin levels fall on a low-carb diet, signaling the kidneys to excrete more sodium. If this isn't compensated with an increased sodium intake, it can lead to the aforementioned symptoms.

2. Nutrient Deficiencies: Fuel for the Brain

The brain is a biochemical factory that produces an array of chemical messengers called neurotransmitters. For this factory to run smoothly, it needs the right fuel, especially B vitamins and iron.

Iron deficiency, in particular, often manifests in symptoms akin to depression, such as fatigue and low mood, making it an important factor to rule out. Like a car running on fumes, a body lacking in essential nutrients can't possibly run at its peak performance.

3. Low Protein Diet: The Missing Building Blocks

Amino acids, the building blocks of protein, are critical to our health. They are encoded by our genes to form enzymes in various sequences. Think of them as an orchestra; each amino is an instrumentalist, and when they play together, they create the symphony of our bodily functions.

Specific amino acids, like tyrosine and tryptophan, are precursors to crucial neurotransmitters dopamine and serotonin, respectively. In essence, a low-protein diet could be the equivalent of missing members in our orchestra, resulting in a lackluster performance and potential mood disturbances.

4. Mitochondrial Health: The Powerhouse Problem

You've probably heard the phrase 'tired but wired'. This can be attributed to the state of our mitochondria, the powerhouses of our cells, which are integral to energy production and overall brain health.

When we face stress, our brain undergoes changes in structure and function—a process called neuroplasticity. This comes at a metabolic cost, which the mitochondria foot the bill for. Those with efficient mitochondrial function are like well-oiled machines—they can meet these energy demands effectively. However, if you have compromised mitochondrial function, you might struggle with these demands, eventually leading to depressive symptoms as your ability to adapt wanes.

5. Hormonal Imbalances: The Endocrine Equilibrium

Hormones are the body's chemical messengers, with estrogen and testosterone playing pivotal roles in brain function. Picture them as conductors in our body's orchestra—they direct the entire performance. If their levels dip, the music can quickly become discordant, leading to anxiety, brain fog, and low mood. Moreover, adrenal glands, which produce cortisol, our 'stress hormone', can also impact mental health when out of balance.

6. The Gut: Your Second Brain

Lastly, we need to address the gut—our 'second brain'. The gut microbiome and the brain are connected through a two-way communication network called the gut-brain axis. Imbalances here can affect mental health.

Short-chain fatty acids (SCFAs), produced by gut bacteria, send signals to the brain and help regulate mood. They're like the mail carriers of our body, delivering vital messages between the gut and the brain.

However, while many people focus on the gut, problems can start higher up in the digestive system. Issues with stomach acid production, pancreatic enzymes, or gallbladder can all impact nutrient absorption. After all, we are not just what we eat, but what we digest. It's like having the ingredients to bake a cake but not having the oven to cook it; you're not going to get the desired outcome.

In conclusion, getting out of a 'funk' involves understanding the complex interplay of various factors within our bodies. Like an intricate piece of music, every element must play its part for the symphony to shine. Armed with this knowledge, you can take steps towards identifying any imbalances and working towards harmony. Stay tuned for future posts where we'll delve into possible remedies and preventive measures for each of these factors. Until then, remember—your body is an orchestra, and every note counts!
