Metabolic Health

Achieving Metabolic Homeostasis: A 3-Step Guide

Metabolic balance is crucial for the survival and proper function of our cells, tissues, organs, and systems.

The balance of metabolism, which generate energy, is crucial as our cells cannot survive without biological power. In addition, the quality of energy also matters for the functioning and performance of cells. Health is all about homeostasis (balance).

Subscribers reading the “metabolic homeostasis” concept in my articles and cited scientific references showed interest in understanding the mechanisms, impacts, implications, and practical ways to maintain it.

As the topic is comprehensive, I only summarize the critical points to give you the big picture and what matters in real life. Interested readers might find voluminous (4K+) scientific papers in PubMed on this topic.

Metabolic homeostasis is vital for proper bodily function and survival. This process is necessary for our cells, tissues, organs, and systems. Any disruption to metabolic homeostasis can lead to diverse health problems.

A balanced metabolism burns energy from fat or carbs effectively. However, unbalanced metabolism converts excessive glucose into fat and stores it. Constantly storing fat makes the belly and other body parts larger. As a result, people get obese and have serious health conditions.

Despite traditional scientists believing that cancers are genetic diseases which is true to some extent, new-generation scientists hypothesize that the root cause might be the compromise of “metabolic homeostasis,” making epigenetic effects, with growing evidence in the literature.

For example, the rate of cancers increased with rising obesity. As CDC informs, “Obesity increases the risk of getting 13 kinds of cancer.” Anthropological studies indicate that our ancestors have fewer cancers than we do today. It is believed to be an evolutionary disease.

I won’t go into scientific details and debate the theories of cancers as it is beyond the scope of this article. However, I will summarize my literature review on this critical topic in another article to inform my readers. In this post, I only touch on theories regarding metabolic homeostasis.

This article aims to explain the concept of metabolic homeostasis, highlight its importance for health, and provide practical tips to create this essential balance via healthy lifestyle choices.

From my findings, there is hope to improve metabolic homeostasis and lower the risk of metabolic disorders with awareness, acceptance, corrective lifestyle changes, and professional support. Our metabolic health also affects our mental health.

What Is Metabolic Homeostasis and Why Does It Matter?

Metabolic homeostasis refers to maintaining a stable environment in the metabolic system concerning metabolic processes to balance energy intake and expenditure for the survival of cells.

The critical factors of metabolic homeostasis are glucose/lipid metabolism, caloric balance, and regulating hormones involved in metabolism.

When metabolic homeostasis is disrupted, it can have profound health implications. For example, if the body takes in more energy than it spends over a prolonged period, it can lead to obesity, type 2 diabetes, and other metabolic disorders.

On the other hand, if the body spends more energy than it takes in and lacks essential nutrients, it can lead to malnutrition, as observed in anorexia patients, and other health problems such as sarcopenia (muscle loss) and even osteoporosis.

The opposite of metabolic homeostasis is metabolic dysregulation, which disrupts the body’s ability to maintain energy balance and leads to problems.

Metabolic dysregulation can occur due to a deficient diet, a sedentary lifestyle, oxidative stress, chronic inflammation, thyroid disorders or other hormonal imbalances, and genetic factors.

What are the key mechanisms?

The balance between energy intake and expenditure is vital for maintaining metabolic homeostasis. An imbalance in this equation can lead to unproportionate fat gain or muscle loss.

More explicitly, when caloric intake exceeds expenditure, the excess energy is stored as body fat. Conversely, when energy expenditure exceeds energy intake, the body uses stored fat as an energy source.

From a hormonal perspective, when blood glucose levels rise after meals, the pancreas releases insulin to facilitate glucose uptake and cell storage.

When blood glucose levels drop, the pancreas releases glucagon to stimulate the liver to release stored glucose into the bloodstream.

Lipids (fat molecules) are broken down into fatty acids and glycerol, which are then used as a source of energy or stored in adipose tissue. The hormone leptin helps to regulate lipid metabolism by suppressing appetite and increasing energy expenditure.

The cells require certain conditions to maintain the balance. They communicate via various biochemicals such as hormones, neurotransmitters, and enzymes.

Metabolic hormones like insulin, glucagon, adiponectin, leptin, and ghrelin are critical in regulating metabolic processes.

The brain and the central nervous system regulate metabolic processes. The hypothalamus regulates appetite and energy expenditure by releasing neurotransmitters.

What are the key theories?

There are two prominent theories covering metabolic homeostasis. They are the set point theory and the lipostatic theory.

The set-point theory suggests that the body has a predetermined weight set-point that it strives to maintain. It proposes that when people try to lose weight, they respond by reducing metabolic rate and increasing hunger to maintain the set-point weight.

The lipostatic theory proposes that adipose tissue regulates energy balance and releases hormones such as leptin and insulin that communicate with the hypothalamus to regulate energy balance and maintain metabolic homeostasis.

Why does metabolic homeostasis matter?

To answer why it matters, I want to touch on the impact and implications of metabolic homeostasis briefly. Disruptions to metabolic homeostasis can negatively impact health, causing metabolic syndrome, obesity, and type 2 diabetes,

Metabolic syndrome is a cluster of conditions that increase the risk of heart disease, stroke, and diabetes. These conditions include high blood pressure, high blood glucose, high triglycerides, low HDL cholesterol, and excess abdominal fat.

Metabolic syndrome is the root cause of type II diabetes, fatty liver disease, cardiovascular diseases, neurodegenerative diseases, and some cancers.

Obesity is gaining excess visceral fat, which can lead to various health problems, including diabetes, heart disease, stroke, cancers, and neurodegenerative disorders.

Type 2 diabetes occurs when the body resists insulin, leading to elevated blood glucose levels. This can result in health complications like nerve damage, kidney damage, and vision problems. Diabetes also can increase the risks of cardiovascular diseases, dementia, and cancers.

Three Practical Steps for Maintaining Metabolic Homeostasis

1 — Get enough calories and nutrients from whole foods.

Three macro-nutrients, carbohydrates, fats, and proteins, turn into energy using enzymes and micro-nutrients, including minerals and vitamins.

Metabolic energy is measured via calories. Excessive and unused calories might turn into body fat via various processes in metabolic pathways.

Excessive or inadequate caloric intake can disrupt metabolic homeostasis, leading to weight gain, muscle loss, and other metabolic health problems.

Consuming adequate proteins and healthy fats is critical for a balanced diet to maintain metabolic homeostasis.

Even though carbs are not essential for the body, eating complex carbs, especially from plants, helps many people.

However, refined carbs in large amounts can break metabolic homeostasis and cause metabolic dysregulation.

In addition to energy, the cells also need specific nutrients like vitamins and minerals. Therefore, we must avoid empty calories and restrictive diets, preventing the consumption of valuable nutrients.

2 — Manage oxidative stress and prevent chronic inflammation.

The World Health Organization classifies stress as the health epidemic of the 21st century. According to The American Institute of Stress, “more than 73% of people regularly experience physical stress.

Oxidative stress can disrupt metabolic homeostasis by impairing glucose and lipid metabolism, causing mitochondrial dysfunction, and activating inflammatory pathways.

Chronic inflammation can disrupt metabolic homeostasis by impairing insulin signaling, dysregulating fat metabolism, causing adipose tissue dysfunction, inducing mitochondrial dysfunction, and overactivation of the immune system.

The body copes with oxidative stress by creating stress hormones. For example, more stress requires more cortisol hormone. Elevated cortisol, which depends on glucose metabolism, can lead to muscle loss and prevent visceral fat burning even if we increase exercise.

Adequate sleep, rest, and timely recovery are essential for metabolic homeostasis, as they can disrupt hormonal regulation and increase appetite causing excess calorie consumption.

In addition, emotional stress can also disrupt metabolic homeostasis. During excess emotional stress, hormones can become imbalanced, and the immune system becomes weak and compromised.

3 — Manage amino acids, glucose, and fat molecules to prevent visceral fat accumulation and muscle loss.

Ideally, we must get all essential amino acids from bioavailable protein sources in an adequate amount and get sufficient calories from healthy fats and complex carbs to maintain our metabolic balance.

This reasonable approach might prevent visceral fat gain unless underlying health conditions, hormonal imbalances, or genetic issues exist.

However, some people consume too many proteins, fats, and carbohydrates, and their calories become visceral fat, usually stored in the abdominal area and buttocks. Therefore, they need to burn these fats first by mobilizing them.

Mobilizing fat is breaking down stored fat into free fatty acids and transporting them into the bloodstream as an energy source. The critical concept to understand is lipolysis.

Specific hormones bind to fat cells when cells and tissues require energy, triggering triacylglycerol hydrolysis.

Hydrolysis means the chemical breakdown of fat due to a reaction with water. Triacylglycerols refer to fatty acids. We need to learn how to influence the body to start the process of lipolysis to mobilize fats.

From my experience and literature reviews, the three practical mechanisms are creating a caloric deficit by reducing food intake, increasing energy expenditure by moving the body, and creating thermic effects by exposing the body to cold temperatures.

So we can mobilize and burn stored fat by lowering calories by eating less, exercising, consuming our food in a specific window (time-restricted eating), and exposing the body to cold (cold showers or ice baths). In a previous article, I provide five tips to melt visceral fat effectively.

As these activities lower the blood glucose and empty glycogen stores, the body starts burning fat, putting the body into ketosis, an alternative energy source using stored fat.

This process also makes the body insulin sensitive and more fat-adapted. An insulin-sensitive body might prevent the formation of metabolic disorders by keeping a good ratio of muscles and fat.

However, if the caloric expenditure is lower than the body’s requirement for a prolonged time, an undesirable situation, called muscle loss leading to sarcopenia, happens. As mentioned before, the body creates more cortisol to cope with the stress of caloric deficit.

Elevated cortisol consumes the glucose from muscles and cannot use visceral fat. In a nutshell, people struggle with muscle loss without being able to lose the desired level of visceral fat.

Takeaways

Metabolic dysregulation can occur due to poor diet, a sedentary lifestyle, oxidative stress, chronic inflammation, thyroid disorders or other hormonal imbalances, and genetic factors.

Here are practical tips for maintaining metabolic homeostasis.

1 — Consume adequate calories and essential nutrients from whole foods.

2 — Avoid empty calories (refined carbs) and restrictive diets.

3 — Managage oxidative and emotional stress and lower inflammation.

4 — Move the body joyfully and regularly, then recover timely.

5 — Get nightly restorative sleep, and meditate, have fun.

6 — Create caloric deficit carefully when needed to lose visceral fat.

7 — Try time-restricted eating, fast-mimicking diets, or keto diets.

8 — Avoid prolonged caloric deficit to prevent muscle loss.

9 — Get your hormones checked and obtain timely treatment.

Remember that balancing energy intake with expenditure is vital for maintaining metabolic homeostasis. An imbalance in this equation can lead to unproportionate fat gain or muscle loss.
