Glossary
Learning and memorizing longevity lingo is a tall task. We want to make it easier for BodyStack members to come up the curve. Use this resource to better understand industry terminology. The definition of many terms are inherently complicated, but we’ve done our best to make it digestible.
Aging and Inflammation - Inflammaging
Inflammaging is a term used to describe the chronic, low-grade inflammation that occurs with aging. It is characterized by an increase in inflammatory markers in the body and is believed to contribute to the development of age-related diseases, such as cardiovascular disease, diabetes, and neurodegenerative disorders. Inflammaging is thought to result from a combination of factors, including the aging immune system, cellular senescence, and environmental influences
Aging is a mitochondrial disease
Mitochondrial disease is a group of genetic disorders that affect the mitochondria, which are the energy-producing organelles within cells. These disorders can result from mutations in either nuclear DNA (inherited from both parents) or mitochondrial DNA (inherited maternally). Treatment options for mitochondrial disease are limited and focus on managing symptoms and supporting overall health and well-being.
Biohacking
A method of using technology, science, and lifestyle changes to improve or optimize various health aspects. Different strategies like diet, supplements, exercise, and therapies could be used to enhance physical and cognitive functions in biohackers.
Biological Age
A person's age, not based on their birth year but determined by their physiological condition and health status. Genetics, lifestyle, and environmental factors can play a role in determining biological age and it is measured using various biomarkers. It's possible biological age can differ from chronological age, and there can even be differences in biological age between various organs in the body.
Biomarkers
Measurable indicators that can be used to assess biological processes, status of disease, or response to treatments in people. Biomarkers studied could vary depending on what is being measured but can include genes, proteins, cells, or other materials that may be present in the body. Biomarkers are used in medical research and clinical diagnosis and can be measured through various bodily fluids, tissue samples, or other biological samples.
Chemicals
A term do describe any number of substances with a distinct molecular composition. Chemicals may be natural or artificial and depending on their composition could have positive or negative impacts on the human body.
Diagnostic
The process of identifying a disease or condition to understand the causes and effects of an illness, disease, or injury. Diagnostic tests can inform decisions on developing a treatment plan.
Functional Medicine
A school of thought within the medical community that focuses on identifying the root causes of disease, rather than just treating the symptoms. To identify these root causes, practitioners consider genetic, environmental, and lifestyle factors that play a role in each specific individual's health and personalized treatments plans are created for a person's unique situation.
Gene
A unit of heredity that is responsible for transmitting traits from parents to offspring. These traits can include physical characteristics like eye color, height, and hair texture, as well as susceptibility to certain diseases or conditions. Genes are made up of DNA and are located on chromosomes within the nucleus of cells. They serve as the instructions for making proteins, which are essential for the structure, function, and regulation of the body's tissues and organs. In the context of fitness, genes can influence factors such as metabolism, muscle growth, and response to exercise.
Genetic
The study of how an individual's genetic makeup influences their physical traits, physiological processes, and responses to external factors like exercise and nutrition.

Information Theory of Aging
The information theory of aging suggests that aging is influenced by the accumulation of damage to genetic information and the loss of information processing capacity within cells and organisms over time. This theory emphasizes the role of entropy, or disorder, in biological systems and proposes that interventions aimed at preserving or restoring information integrity may help delay aging processes.
Lifespan
The length of time an organism is expected to live, typically measured from birth to death.

Metabolic Systems
The interconnected processes within the body that regulate energy production, utilization, and storage. These systems include pathways such as glycolysis, the citric acid cycle, and oxidative phosphorylation, which collectively govern metabolism.
Metabolism
The chemical processes that occur in the body to maintain life. It involves converting food into energy, building and repairing tissues, and removing waste products. Metabolism can also be used to describe how efficiently your body burns calories to maintain basic functions such as breathing, circulating blood, and cell production.
Randomized Controlled Trial (RCT)
A major factor in the rapid advance of medical science over the past 50 years has been the development and refinement of the clinical research method known as the randomized controlled trial (RCT). A clinical trial is defined as a prospective scientific experiment that involves human subjects in whom treatment is initiated for the evaluation of a therapeutic intervention.

This was a figure in Greek mythology who requested that Zeus grant him immortality. However, he did not request eternal youth, so he grew older and weaker ultimately becoming a cricket. This is a cautionary tale with implications suggesting that a healthspan (the number of years you're healthy) is more important than lifespan.
Appetite Regulation
Appetite control is a complex function of the brain that regulates feeding behavior. This function integrates cognitive and emotional factors with a complex array of signals from the gastrointestinal tract and from adipose tissue.
The physiological control of appetite regulation involves circulating hormones with orexigenic (appetite-stimulating) and anorexigenic (appetite-inhibiting) properties that induce alterations in energy intake via perceptions of hunger and satiety.

After intense effort, when ATP deposits are depleted, creatine phosphate donates phosphate groups toward the fast synthesis of ATP. Dietary supplementation with creatine may improve muscle wasting associated with cancer and other chronic diseases.
Dry Fasting

People practicing water fasting may do this as a method of detoxification, for weight loss, or other perceived health benefits, though there are health concerns that are associated with this practice, especially for long durations.
Aerobic Fitness
Aerobic fitness, also known as cardiovascular fitness or cardiorespiratory fitness, refers to the ability of the cardiovascular and respiratory systems to deliver oxygen to muscles during sustained physical activity.
