Think your weight is “fine”? Discover why your body composition score is the true key to active aging and how to combat sarcopenia (muscle loss) with simple, sustainable shifts.

Let me set the scene. I’m 58, I split my time between Singapore and Bangkok, I stay active, I cook my own meals, and — if I may say so — I do not quite look my age. (My words. Also repeatedly, everyone else’s words. I accept the compliment graciously every time.)

So imagine my face when my InBody composition scan came back with a score of 69 out of 100. Sixty-nine. My body is giving itself a C+. In this household — and especially by Asian grading standards — that is essentially a scandal.

But here’s what that number gave me that my bathroom scale never has: actual, useful data. A clear picture of what my body is made of, what needs work, and why. And it’s the reason I want to talk today about why, past a certain age, what you weigh matters infinitely more than how much you weigh.

Where I got this done — and why it’s more accessible than you think

Active Health Lab @ Bedok  ·  Healthy SG Programme

I did my InBody scan at the Active Health Lab at Bedok, which is part of Singapore’s Healthy SG initiative. If you’re a Singapore resident and haven’t explored Healthy SG yet, it’s genuinely worth looking into — these facilities offer proper body composition analysis as part of the programme, not just the usual BMI-and-blood-pressure setup.

At 161cm, my numbers told a story that a regular weigh-in simply couldn’t.

The InBody machine uses bioelectrical impedance to measure your actual body composition — muscle mass, fat mass, water distribution, bone mineral content, visceral fat. It’s not magic; it’s just data. But it’s the kind of data that changes how you think about your health.

My results — let’s be honest about them

Current weight

53.1kg

Target: 55.1kg

Body fat

32%

Above normal range

Skeletal muscle

19.2kg

Below reference

Visceral fat

68.8cm²

Level 6 — to improve

I first went for my baseline assessment in late 2025 (as you can see from my ‘Measuring is Knowing’ folder). I wanted a clear starting point before diving into a more structured approach to my health for 2026. Now, looking back at those results, the data feels more urgent than ever.

Here’s the thing that stops people in their tracks when I show them this: I weigh 53.1kg. At 161cm, that sounds perfectly reasonable. Nobody looks at me and thinks “health concern.” But 32% of that 53kg is fat — above the healthy range for my age and gender. My skeletal muscle mass is below where it should be. And my basal metabolic rate is just 1,150 kcal — low, in part because I don’t have enough muscle tissue driving it up. You can see the full breakdown—including the blunt ‘C+’ reality—in the actual scan report below:

The TOFI reality: This is sometimes called being “Thin Outside, Fat Inside” — a normal scale weight masking an unfavourable ratio of fat to muscle. It’s more common than people realise after 50, and it carries real metabolic risk that the bathroom scale will never flag.

Understanding Sarcopenia: The Silent Muscle Loss.

Here’s what nobody puts in a birthday card: from our mid-30s onward, we lose muscle. Not dramatically, not all at once — just a slow, steady erosion called sarcopenia. By our 50s and 60s, most people who aren’t actively working against it have lost a significant amount of lean mass, often without realising it because the number on the scale hasn’t budged.

• Muscle is your metabolic engine. It burns calories even at rest. Less muscle means a slower metabolism — weight creeps up even when your eating habits haven’t changed.
• Muscle regulates blood sugar. Skeletal muscle is one of the main sites where glucose is absorbed. Lose the muscle, and blood sugar regulation suffers — a direct line toward type 2 diabetes risk.
• Muscle protects your structure. It’s not vanity. It’s your spine, your joints, your posture, your balance. The falls and fractures that sideline people in their 70s? Often rooted in muscle decline that started quietly in their 50s.
• Visceral fat is the hidden troublemaker. Unlike the fat you can pinch, visceral fat wraps around your organs and actively releases inflammatory compounds. Mine sits at level 6 — within the safe zone, but something I’m actively working to reduce.

The number on the scale is total body weight. It tells you nothing about whether that weight is muscle, fat, water, or bone — and after 50, the breakdown is everything.

What I’m actually doing: Prioritizing Functional Strength over the Traditional Gym

I want to be upfront: I have never been a ‘traditional gym’ person. The idea of just standing in a room full of weights doesn’t move the needle for me. What I’ve been building instead is a more intentional, 360-degree approach to my health—one that prioritizes functional longevity and sustainable recovery over ‘heroic’ workouts. I’m interested in the science of how my body works and recovers, not just the sweat.

I’ve always been active. For years, my baseline has been a brisk 90-minute round-trip walk to the beach, three times a week. It’s great for my head and my heart, but as the InBody scan proved, it wasn’t enough to protect my muscle mass.

About 18 months ago, I introduced a 20-minute daily morning ritual. It’s a bit of a ‘greatest hits’ for my longevity: I pack in resistance training, stretching, a mini Tai Chi flow for balance, and even a bit of meditation and chanting to center my mind.

It’s sustainable, I can do it anywhere, and it’s a non-negotiable part of my day. It’s my way of checking in with my body before the world starts asking things of me.

Taking protein seriously — finally

My approach to food has always been intentional, but the InBody data forced me to look closer at my plate. I practice intermittent fasting, so my first meal is usually ‘brukkie’—a combined breakfast and brunch.

In the past, this was purely carb territory: lots of fruit, yogurt, or avocado toast. Now, I’m making small but significant shifts to prioritize muscle synthesis. I’ve started introducing bone broth and sardines into my brunch routine—a simple workaround to hit those protein targets early.

My Current “Protein First” Rules:
No “Carbs-Only” Zones: Every meal, especially brunch, must have a protein anchor.
The Power of Bone Broth: Integrating liquid gold (bone broth) for collagen and protein.
Leftovers with Purpose: Ensuring dinner’s protein serves as tomorrow’s muscle-building fuel.

Jane, Ageisano

It’s a test phase, honestly. I won’t know exactly how effective these shifts are until my next scan, but the goal is clear: no more treating the first meal as a carb-only zone, adding high-quality protein to every lunch, and making sure my leftovers are working just as hard for me the next day.

For reference, the current recommendation for adults over 50 who want to maintain or build muscle is around 1.6–2.2g of protein per kilogram of body weight per day. At 53kg, that’s roughly 85–115g daily — more than most people realise, and more than a single dinner-sized portion of chicken breast.

The good news on visceral fat: It responds well to exactly what I’m already doing — resistance training and increased protein. Of all the fat types, visceral fat tends to shift relatively responsively to lifestyle changes. The machine is already in motion.

Tracking the right numbers

I’ll be doing follow-up body composition scans to track actual muscle mass and fat percentage over time — not just weight. Because here’s the thing: weight can stay completely static while your body composition improves significantly. Muscle is denser than fat. You can lose fat, gain muscle, and the scale might barely move — but the InBody tells a completely different story. If you’re only tracking weight, you’re reading the wrong chapter.

Coming soon — Part 2

My 12-week body recomposition journey with Bixeps

I’m currently midway through a structured 12-week programme with Bixeps , working with the team at Quantum X. In a few weeks I’ll be publishing a full account of that experience — with updated InBody data showing how my muscle mass and body fat have actually shifted over the programme. The numbers are already moving. Watch this space.

What I’d encourage you to do

If you’re in your 50s — or honestly even your late 40s — and you haven’t done a proper body composition analysis, I’d genuinely encourage you to book one. If you’re in Singapore, the Active Health Labs under Healthy SG are an excellent and accessible place to start. Go in without expectations. Let the data tell you what it tells you.

What you learn about your muscle mass, your visceral fat, and your metabolic rate will be far more actionable than anything a scale can offer. And it might just reframe how you think about health at this stage of life — less about being thin, more about being strong, metabolically resilient, and functional for the long run.

I walked out of that lab with a C+. I intend to do something about it. And I’ll show you exactly what that looks like — data and all — very soon.

Part 2 of this series will cover my full experience with the Bixeps 12-week programme at Quantum X, including updated body composition results. This post covers my baseline scan taken at Active Health Lab @ Bedok under the Healthy SG programme.
