Not for vanity. Not for a before-and-after Instagram post. I wanted hard numbers\u2014objective data that cuts through guesswork and tells the truth about body composition, fat distribution, and muscle mass.<\/p>\n<p>DEXA is often talked about in vague terms, so I want to document exactly what mine showed and how I\u2019m interpreting it.<\/p>\n<p><strong>The Raw Numbers<\/strong><\/p>\n<p>At the time of the scan, my stats were:<\/p>\n<ul>\n<li><strong>Height: 177 cm<\/strong><\/li>\n<li><strong>Weight: 104.7 kg<\/strong><\/li>\n<li><strong>Total body fat: 35.0%<\/strong><\/li>\n<li><strong>Fat mass: 35.3 kg<\/strong><\/li>\n<li><strong>Lean mass: 65.5 kg<\/strong><\/li>\n<li><strong>Relative Skeletal Muscle Index (RSMI): 10.40 kg\/m\u00b2<\/strong><\/li>\n<li><strong>Resting Metabolic Rate (RMR): 1,776 kcal\/day<\/strong><\/li>\n<\/ul>\n<p>This immediately tells an important story: I\u2019m not under-muscled. My RSMI sits well above sarcopenia thresholds and is consistent with a strong, load-bearing frame rather than a frail or skinny-fat profile<\/p>\n<p><strong>Muscle Distribution: The Good News<\/strong><\/p>\n<p>Segmental analysis showed that muscle mass in my arms and legs is solid and well balanced left-to-right. Legs in particular carry a large amount of lean tissue, which aligns with strength and movement capacity rather than inactivity.<\/p>\n<p>In other words: this is not a \u201clost muscle\u201d problem. It\u2019s a <strong>fat distribution problem<\/strong> layered on top of a muscular base<\/p>\n<p>That distinction matters because it completely changes the strategy.<\/p>\n<p><strong>Where the Fat Is (And Why That\u2019s the Priority)<\/strong><\/p>\n<p>The scan highlighted elevated fat concentration in the trunk and android (abdominal) region:<\/p>\n<ul>\n<li><strong>Trunk fat: ~44%<\/strong><\/li>\n<li><strong>Android fat: ~48%<\/strong><\/li>\n<li><strong>Visceral Adipose Tissue (VAT): ~2.8 kg<\/strong><\/li>\n<\/ul>\n<p>Visceral fat is the metabolically active kind\u2014the type associated with insulin resistance, cardiovascular risk, and inflammatory signaling. This isn\u2019t about aesthetics. This is about risk management.<\/p>\n<p>The DEXA heat map makes this impossible to ignore: the issue is central fat, not overall size.<\/p>\n<p><strong>Why Scale Weight Is a Terrible Metric<\/strong><\/p>\n<p>If I lost 15\u201320 kg without preserving muscle, the scale would look great and the outcome would be worse.<\/p>\n<p>DEXA makes it clear that the correct objective is:<\/p>\n<ul>\n<li><strong>Reduce fat mass aggressively<\/strong><\/li>\n<li><strong>Preserve (or even improve) skeletal muscle<\/strong><\/li>\n<li><strong>Shift fat distribution away from visceral storage<\/strong><\/li>\n<\/ul>\n<p>That\u2019s not something you track with a bathroom scale.<\/p>\n<p><strong>Metabolism: No Excuses Here<\/strong><\/p>\n<p>An RMR of ~1,776 kcal\/day is normal for my lean mass. There\u2019s no \u201cbroken metabolism\u201d narrative to hide behind. Fat loss here is not about metabolic damage\u2014it\u2019s about sustained energy control and consistency.<\/p>\n<p>That\u2019s actually good news, because it means the system responds predictably when the inputs are correct.<\/p>\n<p><strong>The Real Value of This Scan<\/strong><\/p>\n<p>What this scan gave me is <strong>clarity<\/strong>.<\/p>\n<ul>\n<li><strong>I know muscle is not the limiting factor.<\/strong><\/li>\n<li><strong>I know exactly where the fat is.<\/strong><\/li>\n<li><strong>I know what type of fat matters most.<\/strong><\/li>\n<li><strong>I have a baseline that future scans can objectively compare against.<\/strong><\/li>\n<\/ul>\n<p>This turns body recomposition into an engineering problem instead of a motivational one.<\/p>\n<p><strong>Final Thought<\/strong><\/p>\n<p>Most people never get this level of feedback. They chase weight loss blindly, lose muscle, stall, and then assume age or genetics are the problem.<\/p>\n<p><strong>DEXA removes the guessing.<\/strong><\/p>\n<p>Now it\u2019s just execution.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tweet I recently had a full-body DEXA scan done.
