Body fat percentage: Key facts and practical strategies
Body fat percentage is an important indicator of health and general wellbeing. In this blog post, we explain the basics of body fat percentage, its significance and effective strategies for achieving a healthy level.
This article is aimed at anyone interested in body fat percentage who would like to learn more about the subject.
Basics of body fat percentage
Definition of body fat
Body fat is the fatty tissue found in our bodies. It consists mainly of fat cells known as adipocytes. A distinction is made between essential fat and storage fat, depending on their function and location.
Functions of body fat in the body
Body fat performs several important functions in the body, including:
Energy storage
Fat is an efficient energy store that the body can draw on when needed.
Thermal insulation
Fat tissue insulates the body and helps regulate body temperature.
Protection of internal organs
Fat tissue acts as cushioning that helps protect the internal organs from impact and injury.
Hormone production
Fat tissue produces hormones such as leptin, which regulates food intake and body weight.
Difference between essential fat and storage fat
Not all fat is the same. There are important differences between essential fat and storage fat.
Essential fat
Essential fat is necessary for maintaining normal bodily functions. It is found in areas including nerve cells, bone marrow, internal organs and cell membranes, and plays a key role in hormone production, insulation, organ protection and cell structure.
In men, essential body fat accounts for approximately 2–5%, while in women it is around 10–13%, as women require additional fat for reproductive functions.
Storage fat
Storage fat accumulates in fat cells beneath the skin, known as subcutaneous fat, and around the organs, known as visceral fat. It serves as an energy reserve that can be mobilised when energy requirements increase.
A healthy amount of storage fat supports wellbeing and energy supply, but too much can carry health risks.
Factors that influence body fat percentage
Several factors influence body fat percentage, including:
Age
Body fat percentage tends to increase with age.
Sex
Women generally have a higher proportion of body fat because they require more essential fat.
Genetics
Genetic predisposition influences how much fat a person stores.
Diet and physical activity
A balanced diet and regular physical activity help regulate body fat percentage.
Hormonal changes
Life stages such as puberty, pregnancy and the menopause can affect body fat percentage.
Stress
Chronic stress increases cortisol levels, a hormone that can encourage fat storage.
Because body fat percentage is an important health indicator, it is worth keeping an eye on it and taking appropriate measures when needed.
Measuring body fat percentage
Accurate measurement is essential for recognising progress and assessing strategies objectively.
Different methods of measuring body fat percentage
Bioelectrical impedance analysis (BIA)
This method measures electrical resistance in the body. Fat tissue has a higher resistance than muscle mass or water. Results can be influenced by hydration, meals or activity, but BIA remains a practical and cost-effective option.
Skinfold measurement
With this method, the thickness of skinfolds is measured at different points on the body. Accuracy depends heavily on the experience of the person carrying out the measurement. Nevertheless, it is a straightforward and inexpensive option.
Hydrostatic weighing
This method, also known as underwater weighing, measures buoyancy in water in order to calculate body fat percentage. It is highly accurate, but requires specialist equipment and is more expensive than other methods.
Dual-energy X-ray absorptiometry (DEXA)
DEXA is an imaging method that uses two X-ray energy levels. It provides highly precise data on body fat, lean mass and bone density. Due to its higher cost and limited availability, it is mainly used for scientific purposes.
Recommendations for the most common uses
For everyday use, BIA and skinfold measurements are usually sufficient for tracking trends in body fat percentage. They are inexpensive, simple and easily accessible.
For precise scientific analysis or high-performance athletes, DEXA and underwater weighing offer greater accuracy, although they require more resources.
When choosing a suitable measurement method, individual needs, accuracy, cost and availability should all be taken into account.
In the next section, we look at how a healthy body fat percentage can be achieved, with practical tips and recommendations.
Optimal body fat percentage and health risks
A healthy body fat percentage contributes significantly to general wellbeing. Regular measurements and considered lifestyle choices, such as a balanced diet and physical activity, can help minimise health risks. If you are unsure, it is advisable to consult a doctor or nutrition professional.
Recommendations for a healthy body fat percentage by sex and age
The optimal body fat percentage varies depending on sex, age and individual factors. The following values are generally used as guidelines:
Body fat percentage for men
| Age group | Good | Average | High |
|---|---|---|---|
| 18–24 years | 8–12% | 13–17% | 18–22% |
| 25–34 years | 10–15% | 16–20% | 21–25% |
| 35–44 years | 12–17% | 18–22% | 23–27% |
| 45–54 years | 14–19% | 20–24% | 25–29% |
| 55–64 years | 16–21% | 22–26% | 27–31% |
| 65+ years | 18–23% | 24–28% | 29–33% |
Body fat percentage for women
| Age group | Good | Average | High |
|---|---|---|---|
| 18–24 years | 16–20% | 21–25% | 26–30% |
| 25–34 years | 18–22% | 23–27% | 28–32% |
| 35–44 years | 20–24% | 25–29% | 30–34% |
| 45–54 years | 22–26% | 27–31% | 32–36% |
| 55–64 years | 24–28% | 29–33% | 34–38% |
| 65+ years | 26–30% | 31–35% | 36–40% |
These values serve as general guidance. Individual differences should always be taken into account. If you are unsure or have health-related questions, it is advisable to speak to a healthcare professional or nutritionist.
Risks of a body fat percentage that is too high
Health effects
A higher body fat percentage can be associated with a range of health problems, including:
i) Cardiovascular disease: Excess body fat can increase blood pressure and cholesterol levels and raise the risk of heart attack and stroke.
ii) Type 2 diabetes: Being overweight or living with obesity can impair insulin sensitivity and therefore increase the risk of type 2 diabetes.
iii) Sleep apnoea: Fat deposits around the neck can block the airways and lead to pauses in breathing during sleep.
iv) Joint strain: Excess body weight increases the load on the joints and can contribute to chronic problems such as osteoarthritis.
Psychological effects
Mental wellbeing can also be affected:
i) Self-esteem: People with a high body fat percentage are more likely to experience a negative body image.
ii) Depression: Studies show an association between excess weight and an increased risk of depressive symptoms.
Risks of a body fat percentage that is too low
Hormonal disturbances
A body fat percentage that is too low can disrupt hormone production, particularly oestrogen and testosterone, and may contribute to menstrual irregularities, infertility or osteoporosis.
Weakened immune system
Insufficient body fat can impair immune function and increase susceptibility to infections.
Impaired temperature regulation
Fat acts as thermal insulation. A very low body fat percentage can reduce the body's ability to regulate temperature, resulting in greater sensitivity to cold.
Strategies for reducing body fat percentage
Dietary changes
a) Calorie balance: To reduce body fat, a calorie deficit is required, meaning that you consume less energy than you use. Individual requirements depend on age, sex, weight and activity level.
b) Macronutrient distribution: A balanced distribution of protein (25–30%), fat (20–35%) and carbohydrates (45–60%) is essential for a healthy reduction in body fat percentage.
c) Micronutrients: Vitamins and minerals support numerous metabolic functions. A varied diet containing fresh foods helps meet these requirements.
d) Recommended foods:
- Fresh fruit and vegetables
- Wholegrain products, such as oats, quinoa and brown rice
- Lean protein, such as poultry, fish and pulses
- Healthy fats, such as avocado, nuts and olive oil
- Low-fat dairy products, such as yoghurt and cheese
Regular physical activity
a) Endurance exercise: Activities such as running, swimming or cycling promote fat burning. The recommendation is at least 150 minutes of moderate or 75 minutes of vigorous physical activity per week.
b) Strength training: This promotes muscle development and increases basal metabolic rate. Two training sessions per week covering all major muscle groups are considered ideal.
c) Recovery: Sleep and rest are central to physical performance. Aim for 7–9 hours of sleep per night and planned recovery periods after intense exercise.
Lifestyle changes
a) Stress management: Stress increases cortisol production, which can encourage fat storage. Techniques such as meditation, yoga and breathing exercises can help reduce stress.
b) Social support: Support from friends and family can encourage motivation and long-term success.
c) Goal setting: Set realistic goals, document your progress and use different measurement methods such as body weight, body measurements or exercise performance.
Food supplements
Nutraceuticals can be a useful addition when incorporated into a healthy lifestyle. They do not replace a balanced diet or physical activity, but they may offer additional support.
Examples of supportive ingredients include:
- Green tea extract: Contains catechins, which may stimulate metabolism and support fat burning.
- L-carnitine: Supports the transport of fatty acids into the mitochondria for energy production.
- Garcinia cambogia: Contains HCA, which may help reduce appetite and fat storage.
- Chitosan: A natural fibre that may bind fats in the digestive tract and reduce their absorption.
Tyrexin combines these active ingredients in one product, including CLA (conjugated linoleic acid). The combination may promote metabolism, support fat burning and reduce feelings of hunger.
Remember that food supplements such as Tyrexin can be valuable companions, but they can only reach their full potential when combined with a healthy diet, physical activity and a sustainable lifestyle.
Summary
Reducing body fat percentage can be achieved through a combination of mindful eating, regular physical activity and a balanced lifestyle. A varied diet containing both macro- and micronutrients, combined with endurance and strength training, forms the foundation.
This can be complemented by stress management, social support and clear goals. Regularly reviewing your progress and setting realistic milestones can help create sustainable long-term changes for greater vitality and quality of life.
