Visceral fat is often discussed in relation to abdominal weight and overall health, but understanding its role requires looking beyond what you can see in the mirror. It differs from the tissue stored just beneath the skin and has distinct effects on the body.

This guide explores how visceral fat is assessed and how personal training can support healthier body composition.

What Is Visceral Fat and Why Does It Matter?

Visceral fat is stored within the abdominal cavity, surrounding organs and accumulating in areas such as the mesentery, the tissue that supports and connects the intestines. Unlike fat that primarily serves as an energy reserve, this tissue is biologically active, releasing fatty acids and signalling molecules that influence inflammation and how the body regulates energy.

Some visceral fat is necessary because it cushions and protects internal organs. However, excessive accumulation can disrupt normal bodily functions and increase the risk of health complications.

Visceral Fat vs Subcutaneous Fat: What's the Difference?

The main difference between these two types of fat is where they are stored and how they interact with the body.

This distinction also explains why someone can have a BMI within the conventional healthy range while carrying excess visceral fat. Sometimes informally described as being skinny fat, this highlights how body weight alone cannot reveal body composition or show where excess tissue is concentrated. 

What Causes Visceral Fat to Build Up?

Several factors can contribute to increased abdominal fat storage:

• Excess calorie intake: Consistently consuming more energy than the body uses can lead to additional energy being stored. 

• Physical inactivity: Spending long periods sitting and exercising infrequently can affect energy balance and body composition.

• Nutritional habits: Frequent consumption of energy-dense foods, sugary drinks and excessive alcohol can make weight management more difficult.

• Chronic stress: Prolonged stress can influence cortisol levels, appetite and eating behaviours, potentially contributing to abdominal fat accumulation.

• Poor sleep: Inadequate sleep can affect appetite regulation and insulin sensitivity, making healthy weight management more challenging.

• Ageing and hormonal changes: Menopause and age-related changes can influence how and where the body stores fat.

• Genetics: Inherited factors contribute to differences in body shape and how tissue is distributed. 

Age-related muscle loss, known as sarcopenia, can also affect body composition. As muscle mass declines, changes in energy expenditure may make it more difficult to maintain previous weight levels without adjusting activity and nutritional habits.

How to Know If You Have Visceral Fat

Visceral fat cannot be reliably identified through appearance or touch alone. A larger waist circumference may indicate increased central adiposity, but further assessment is needed to understand fat distribution.

Several methods can provide additional insight:

1. Waist Circumference

Measuring around the waist provides a practical indication of central adiposity. Common clinical thresholds include 80 cm for women and 94 cm for men in certain UK and European guidance, although appropriate cut-offs vary by ethnicity and clinical context.

2. Waist-to-Height Ratio

Divide your waist circumference by your height using the same units. A ratio below 0.5 is a commonly recommended target for many adults.

3. Body Mass Index (BMI)

This compares weight with height to provide a general weight classification. However, it cannot distinguish between muscle and fat or identify where fat is stored.

4. Body Composition Assessments

Bioelectrical impedance analysis (BIA) scales estimate visceral fat using device-specific algorithms. MRI and CT scans provide more direct assessments but are not routinely necessary for general fitness monitoring.

Home BIA readings can fluctuate with hydration, recent exercise, food intake and measurement conditions. Using the same device under consistent conditions and monitoring longer-term trends is more useful than reacting to individual daily readings.

What Is a Healthy Visceral Fat Level?

A healthy visceral fat level depends on the body composition scale being used. For example, Omron classifies ratings of 1 to 9 as normal, while Tanita considers 1 to 12 healthy. These ranges are specific to each manufacturer's measurement system, so there is no universal numerical threshold that applies to everyone.

Smart scales estimate visceral fat rather than measuring it directly. When interpreting your results, consider the following:

• Follow the manufacturer's reference range: Use the guidance provided for your specific device.

• Monitor longer-term trends: Take readings under consistent conditions and compare results over several weeks rather than focusing on daily fluctuations.

• Consider other health indicators: Waist circumference can provide additional insight into central adiposity, although it cannot independently confirm changes in visceral fat.

Why Is Excess Visceral Fat a Health Concern?

Excess visceral fat can affect how the body regulates blood glucose, processes fats and maintains cardiovascular health. Higher levels are associated with an increased risk of several conditions, including:

• Insulin resistance: Reduced sensitivity to insulin can make blood glucose regulation more difficult.

• Type 2 diabetes: Insulin resistance can increase the likelihood of developing this condition.

• Cardiovascular disease: Excess abdominal fat is linked to a higher risk of heart disease and circulatory problems.

• High blood pressure and abnormal blood lipids: These conditions commonly occur alongside excess abdominal fat.

• Metabolic dysfunction-associated steatotic liver disease (MASLD): Excess visceral fat can contribute to fat accumulation in the liver.

One explanation involves the hepatic portal circulation. Fatty acids released by visceral tissue can travel directly to the liver through the portal vein, influencing liver function and potentially contributing to insulin resistance.

How Can You Reduce Visceral Fat Naturally?

Reducing excess visceral fat involves consistent changes to physical activity, nutrition and everyday habits. Combining regular exercise with balanced eating and adequate recovery can help improve body composition over time. 

Combine Strength Training and Cardiovascular Exercise

Both resistance training and aerobic activity play important roles in managing body fat.

• Resistance training: Exercises such as squats, lunges, presses and rows help develop and preserve muscle mass.

• Cardiovascular exercise: Activities such as brisk walking, cycling and swimming increase physical activity and support energy expenditure.

• High-intensity interval training (HIIT): Alternating short periods of intense activity with recovery intervals can provide another way to incorporate cardiovascular exercise.

• Combined training: Incorporating resistance and aerobic activities supports strength, endurance and overall metabolic health. 

Muscle tissue also plays an important role in blood glucose regulation. During exercise, contracting muscles increase their uptake of glucose from the bloodstream. Regular resistance training can help preserve muscle mass and support insulin sensitivity. These approaches also contribute to reducing stubborn belly fat.

Develop Sustainable Nutritional Habits

Rather than following restrictive diets, focus on balanced eating patterns that support gradual changes in body composition. Prioritise:

• Adequate protein: Include eggs, fish, lean meat, dairy and legumes to help maintain muscle.

• Fibre-rich foods: Vegetables, fruit, whole grains and beans promote satiety, support digestion and contribute to metabolic health.

• Balanced portions: Maintain an appropriate energy intake to encourage gradual reductions in excess body weight.

• Moderate alcohol consumption: Limit excessive intake to reduce additional calorie consumption and support metabolic health.

Prioritise Sleep and Stress Management

Consistent sleep and effective stress management can help regulate appetite, support recovery and maintain healthy routines. Aim for adequate rest, follow a regular sleep schedule and incorporate activities that help manage everyday stress. 

How Do Personal Trainers Help You Lose Visceral Fat?

Personal trainers can help individuals manage excess visceral fat through structured workouts, practical nutritional guidance and ongoing progress monitoring. Their role is to develop an approach that reflects each client's fitness level, physical capabilities, lifestyle and goals.

Create a Personalised Exercise Programme

A professional trainer can review a client's exercise history, movement patterns, posture and current fitness level before developing a suitable programme.

This may involve:

• Assessing movement and posture to identify areas requiring attention.

• Selecting exercises that accommodate individual abilities and physical limitations.

• Combining progressive resistance work with cardiovascular activity.

• Adjusting intensity as strength and fitness improve.

This process helps ensure that each programme reflects the client's fitness level, movement needs and longer-term goals. 

Provide Nutritional Guidance and Accountability

Maintaining consistent eating habits can be challenging without appropriate guidance. Within their professional qualifications, personal trainers can help clients understand energy balance, make practical dietary adjustments and develop more balanced eating patterns.

Regular coaching also provides accountability, encouraging consistency with exercise and everyday habits.

Monitor Progress and Adapt Training

Changes in body weight are only one measure of progress. Trainers can also monitor:

• Strength and cardiovascular performance.

• Exercise technique and movement quality.

• Waist circumference and relevant body composition indicators.

• Training consistency and improvements in fitness.
