Men’s Health, and the Power of Measurement with the Evolt 360

As men age, their body composition changes, often in ways that are invisible to the eye but critical to long-term health. The gradual gain of visceral fat and decline in skeletal muscle mass form a potent combination that drives many age-related diseases.  

The Evolt 360 Body Composition Scanner allows men to measure both reliably and non-invasively, providing a foundation for targeted action through nutrition, exercise, and evidence-based supplementation.  

What is visceral fat?  

Visceral fat is stored deep within the abdominal cavity, surrounding internal organs such as the liver, pancreas and intestines. Unlike subcutaneous fat, it acts like a hormone-secreting organ, releasing inflammatory cytokines and adipokines that can disrupt insulin sensitivity, impair vascular function, and increase the risk of heart disease and type 2 diabetes.12  

Over time, excessive visceral fat contributes to chronic low-grade inflammation, insulin resistance, and metabolic dysregulation, all strong predictors of morbidity and mortality independent of body mass index (BMI).  

Why men are more susceptible  

Men naturally carry more visceral fat than women. Testosterone promotes lean mass and limits fat storage, but as men age, testosterone gradually declines, leading to increased fat deposition, particularly around the abdomen as well as reduced muscle mass. Meanwhile, women’s higher estrogen levels during pre-menopause favour more subcutaneous fat storage. This explains why many men develop the classic ‘central obesity’ pattern in midlife.3  

Why skeletal muscle must be measured alongside visceral fat  

Skeletal muscle is far more than a strength or aesthetic marker, it’s a metabolically active endocrine organ that influences glucose uptake, energy expenditure, and hormone regulation. When muscle mass declines, insulin sensitivity falls, testosterone may decline further, basal metabolism drops, and inflammation increases.4 Assessing both skeletal muscle and visceral fat therefore provides a very good picture of hormonal and metabolic health. The Evolt 360 quantifies both metrics, allowing men to identify early imbalances before they translate into fatigue, low libido, metabolic syndrome or cardiovascular disease.  

Nutrition — the cornerstone of change  

Protein intake is crucial for maintaining skeletal muscle, regulating hormones, and supporting metabolic health. Studies show that protein-rich diets can reduce visceral fat accumulation and preserve lean mass during weight-management interventions. Scientific reviews confirm that higher daily protein intake, within safe levels up to approximately 2.4 g per kg of body weight for healthy adults, are well-tolerated and beneficial for active individuals.5 Ensuring adequate, evenly distributed protein across meals helps sustain muscle protein synthesis, promotes satiety, and supports the maintenance of metabolic rate during body-fat reduction. A moderate energy deficit achieved through nutrient-dense food choices is essential for reducing visceral fat. Combining calorie control with resistance and aerobic training produces the greatest improvements in trunk-fat reduction while maintaining muscle mass.6  

Supplements can complement nutrition and training when used appropriately. Consulting a qualified healthcare professional or dietitian ensures that any supplementation, such as probiotics, omega-3 fatty acids, or micronutrients supporting hormone balance and recovery, aligns with individual needs.  

Exercise — the hormonal amplifier  

Both resistance and high-intensity interval training are proven to reduce visceral fat and improve testosterone levels. Regular training enhances insulin sensitivity, lowers inflammation, and stimulates muscle growth, restoring many hormonal dynamics that decline with age.7  

Measuring progress with the Evolt 360  

The Evolt 360 enables men to quantify visceral fat rating, measure skeletal muscle mass and distribution, and monitor the fat-to-muscle ratio and Bio-Wellness Index to visualise overall metabolic trends. Regular scans, recommended every 4 weeks, objectively evaluate whether nutrition, exercise and supplementation strategies are producing meaningful improvements, turning data into direction.  

Putting it all together  

1. Scan – Establish baseline visceral fat and skeletal muscle levels.  

2. Plan – Build a nutrition approach that emphasises adequate protein and overall calorie control.  

3. Train – Prioritize resistance training and complement with cardiovascular work.  

4. Consult – Engage a health professional for further medical testing, tailored supplementation and hormone-health advice.  

5. Re-scan – Use the Evolt 360 every 4 weeks to track body-composition change and refine your plan over time.  

For men, health and longevity depend on maintaining the right balance between muscle and fat. Tracking only body weight misses the underlying story. The Evolt 360 bridges that gap, empowering men to measure visceral fat and skeletal muscle together, understand their hormonal drivers, and take evidence-based steps toward sustainable, goal-driven body-composition change.
