Lost the Weight – Still the Belly

[OPENING HOOK — 0-15s]

I averaged 4,295 steps a day for thirteen months. I never set foot in a gym. I lost four-and-a-half stone.

[OPENING BRIDGE — 16-30s]

That’s not the interesting part. The interesting part is what was happening to my muscle the entire time — because nobody told me, and I wasn’t measuring it. By the time I started lifting, I found something in the data that I hadn’t expected.

[OPENING ROADMAP — 31-60s]

I’m Neil — NHS blood tests going back to 2012, off all medication since February 2024. And the thing I’m about to show you is that muscle loss in midlife is the one metabolic change that doesn’t show up on a scale, doesn’t show up in a blood test, and happens quietly while everything else is improving. The sequencing of how I did this turned out to matter. Today I’m going to walk you through all of it with the data.

First — what 4,295 steps a day actually did to my body over thirteen months: the fat loss, the biomarker changes, and the one marker that only moved when I added resistance. | Then — what the blood tests showed when I finally started lifting: a number that made my GP ask if I’d gone back on statins. | Then — what this tells us about the sequence, and why the order matters more than the effort.

THE SCIENCE (5-7 minutes)

Muscle strength declines two to three times faster than muscle mass with age.

That’s not a rough estimate — that’s what the data says. Peter Attia, citing research from Andy Galpin at Cal State Fullerton, puts it simply: by the time you notice you’ve lost mass, the underlying strength has already been declining for years. The fast-twitch type 2 muscle fibres — the ones responsible for power, for the ability to catch yourself when you stumble, for explosive movement — those go first, and they go quietly.

Most people don’t notice because muscle mass changes slowly. You don’t step on the scale and read “less muscle.” It doesn’t show up in your cholesterol results or your HbA1c. You feel a bit weaker. You notice stairs are harder. You assume it’s just getting older.

But here’s what I didn’t understand when I was walking those 4,295 steps a day — it isn’t just getting older.

ANA-196 — Muscle as Long-Term Metabolic Asset

Think of muscle mass like money in the bank — and this becomes more true with every decade you age.

At 45, it’s a nice savings account. Useful, worth protecting, but not urgent. At 65 it’s your pension. The people who can still get off the floor unassisted at 80, carry shopping without stopping halfway up the path, crouch down to a grandkid without needing a wall to haul themselves back up — they started making deposits at 50.

Sarcopenia — the medical term for age-related muscle loss — starts in your thirties and accelerates if you don’t actively work against it. It’s a diagnosable condition, not an inevitable fact of ageing. And what the research shows, consistently, is that resistance training is the primary intervention. Not the only tool. The primary one.

Stuart Phillips and Neil McCartney put the numbers on it: muscle loss begins around 40 and progresses at roughly 1 to 2 percent per year. By the eighth decade — your 70s, your 80s — up to 40 percent of peak muscle mass may be gone. Jack Mosley — GP registrar, MRes in Diabetes — says it plainly: muscle peaks between 30 and 35, declines gradually through your forties, accelerates after 50, and after 60 you can lose more than 10 percent per decade.

You’re not just losing how you look. You’re losing metabolic capacity.

Here’s why that matters so much, and why it isn’t just about strength.

Cyrus Khambatta — exercise physiologist, spent years working with people with type 2 diabetes — describes muscle tissue as one of the body’s primary sites for glucose disposal. More muscle mass means greater capacity to absorb glucose from the blood. Resistance training, in his work, is the most effective exercise modality for improving insulin sensitivity — not because of calories burned, but because of what muscle does metabolically, at rest, around the clock.

Muscle is a metabolic endocrine organ. It pulls glucose from the bloodstream, secretes hormones that communicate with the brain, fat, and bone. Its structural role — the ability to lift things and move — is almost the least of what it does.

Tim Spector makes this point in a way I find useful: exercise is largely ineffective for weight loss. Only about 10 percent of total energy expenditure can be manipulated through physical activity. The pre-set resting metabolic rate — which is largely determined by lean muscle mass — accounts for 70 percent.

Which means: the reason 4,295 steps a day worked for fat loss wasn’t primarily the calories I was burning walking. It was what fasting and non-UPF eating had done to the metabolic environment. The walking kept me moving, kept insulin sensitivity improving, reduced inflammatory load. But the fat loss was driven by the food and fasting decisions.

And that distinction matters. Because it means I was potentially losing fat, fixing biomarkers — and quietly losing muscle the whole time, without knowing it.

This mechanism doesn’t wait for a GP to notice it. It operates in the background for years before it causes functional problems. Understanding it at 42 or 52 gives you more options than understanding it at 62.

ANA-189 — Intramuscular Fat Infiltration

An orthopaedic surgeon put three CT scans side by side: a 40-year-old triathlete, a sedentary 70-year-old, and an active 74-year-old.

The triathlete’s muscle was dense and clean. The sedentary 70-year-old’s looked like a Sunday joint — all that marbling you have to trim before you’d want to eat it. The active 74-year-old? Clean as a lean steak. Four years older than the sedentary person, structurally younger in every meaningful sense.

That marbling isn’t just aesthetic. It’s intramuscular fat — fat that has infiltrated the muscle tissue itself — and it impairs strength, slows metabolism, and drives insulin resistance in a way that dietary change alone cannot fully address. You can fast, eat well, fix your blood sugar — and still have intramuscular fat accumulating inside the muscle tissue if you’re not providing a resistance stimulus.

The active 74-year-old’s clean CT scan wasn’t down to genetics. It was down to staying active through the years when most people stop.

You don’t have to be a triathlete. You just have to kTexteep moving — and eventually, add the right kind of movement.

Common misconception worth addressing:

A lot of people believe that if they lose weight without lifting, they must have lost muscle. The assumption: fat loss equals muscle loss, so you need to compensate by eating more protein or exercising harder.

The reality is more nuanced. Whether muscle is preserved during fat loss depends primarily on the metabolic environment — insulin sensitivity, protein adequacy, the presence or absence of a resistance stimulus — not purely on exercise volume.

My walking-first phase wasn’t laziness. It was addressing the metabolic environment first: fixing insulin sensitivity, reducing inflammation, getting the system working. That’s what the data eventually told me. The walking wasn’t doing nothing. It was building the foundation on which resistance training would later multiply.

The sequencing wasn’t accidental. It turned out to be correct.

MY EXPERIENCE (4-6 minutes)

December 2023. NHS blood test. Total cholesterol 8.0 mmol/L. HDL — the so-called good cholesterol — at 1.3. I’d been on statins for eleven years at that point.

Here’s what I found when I went back through the records: HDL in 2012 was 1.6. By 2016 it was 1.51. By 2020, 1.33. By December 2023, 1.3. Eleven years on statins and the good cholesterol had been quietly dropping the whole time. (WMTWL-EVID-105)

That was news I hadn’t been given. The cholesterol/HDL ratio — which is more predictive of cardiovascular risk than total cholesterol alone — was sitting at 6.15. Target is under 5.0. I was nowhere near it.

February 2024. Stopped statins. Started eating properly. Fasting, non-UPF, the system I’d been building since Boxing Day 2023. Started walking — 4,295 steps a day on average, sometimes less on fasting days when my body naturally conserved energy and dropped to around 2,971. No structured exercise. No gym. Just the walking.

Thirteen months later. April 2025. Blood test results.

My GP opened the file. There was a pause. Then: “Are you back on statins?”

I shook my head. “No. Been off them since February 2024.”

He scrolled through the numbers. Total cholesterol down. LDL down. HbA1c at 37 — out of pre-diabetic range for the first time in years. CRP down 84 percent. And HDL: 1.5. Up from 1.3. A 15 percent improvement. More importantly, the cholesterol/HDL ratio: 4.7. Within target range for the first time in over a decade. (WMTWL-MOM-243)

“This is better than when you were on medication,” he said. “What are you doing?”

Now — here’s the important bit about timing, because this is where the sequencing matters.

The HDL improvement coincided with two things happening simultaneously: stopping statins, and starting resistance training. I’d added structured lifting — weighted squats, lunges, upper body work — around month two of the journey, building gradually. By the April 2025 blood test, I’d had roughly fourteen months of consistent resistance training. (WMTWL-MOM-242)

HDL responds to physical stimulus. It responds to the metabolic stress of lifting, the hormonal signals that resistance training creates. Pills don’t build HDL. Pills lower total cholesterol. Movement — specifically resistance movement — appears to build the good stuff.

I can’t tell you with certainty that the resistance training caused the HDL improvement, because I was also fasting, eating differently, off statins. Multiple things changed simultaneously. Honest answer: I don’t know exactly which input moved which needle. What I can say is that the HDL had been falling for eleven years despite statins, and it started rising fourteen months after I stopped them and started lifting.

The other data point I want to be honest about — because it complicates the clean narrative.

First 90 days: 2.4 stone lost. Felt incredible. Then around the 180-day mark, the scale went up slightly. Two pounds regained. (WMTWL-MOM-256) I panicked initially. Then measured. Waist down. Lifts up. Energy better.

Body recomposition. Fat loss and muscle gain happening simultaneously. The scale went up because muscle was displacing fat — muscle is denser. The scale lied. The tape measure told the truth.

And by November 2025, I was at 13 stone 3 — slightly over the number I’d hit after a brutal 21-day fast the previous summer. But the measurements were seven inches smaller total. Same weight. Completely different body. (WMTWL-MOM-308)

The intramuscular fat scan — the one the orthopaedic surgeon described — that’s what I think was changing. Not the number on the scale. The quality of the tissue underneath.

The thing I couldn’t see during the walking-only phase is this: I was walking 4,295 steps a day, losing fat, improving every biomarker my GP could measure. But muscle — the metabolic organ, the pension account — was likely being quietly drawn down the whole time.

Not catastrophically. Not in a way that showed up. But the withdrawals were happening.

When I added resistance training, the deposits started. And fourteen months later, a number moved that hadn’t moved in over a decade. My GP asked if I was back on medication.

I wasn’t. I’d just started paying the pension contributions.

WHAT I’D ACTUALLY CHANGE (2-3 minutes)

If I were starting this from scratch, knowing what the data now shows, the one thing I’d have done earlier is add resistance training sooner.

Not immediately. I still think the walking-first phase was correct — fixing the metabolic environment before loading the system. If I’d tried heavy lifting in January 2024 when I was still inflamed, still pre-diabetic, still on statins, I think the risk of injury and burnout would have been significant. The gym visits in 2019 — when I tried lifting before the foundation was in place — confirmed that. I went five sessions a week. The weight went up.

The metabolic environment wasn’t ready. The loading was premature.

But somewhere around month three or four — not month thirteen — I’d have started. Bodyweight first. Squats, lunges, press-ups. Enough stimulus to tell the muscle: we’re not closing the factory. Then gradually loaded, once the pattern was consistent.

What resistance training looks like for me now, for reference: weighted squats, weighted lunges, dumbbell work — three movements, three sets of eight to fifteen reps working close to failure, three times a week. When set one hits fifteen reps comfortably, the weight goes up. That’s it. No gym membership required. Rucksack and bodyweight got me started.

ANA-127 — Independence Insurance

Here’s how I frame resistance training now.

It’s your independence insurance policy. You’re not paying premiums for a beach body or to compete with the lads at the gym. You’re paying so that at 75 you can get off the floor in your living room without yelling for help. Carry two Aldi bags from the car without stopping halfway up the path, gasping. Crouch down to tie your grandkid’s shoelaces at the park without needing a wall to haul yourself back up.

That’s the policy payout. Not six-pack abs. Not a deadlift personal best. Function. Independence. Dignity.

You’re 50 now. Pay the premiums — two or three thirty-minute sessions a week. At 75, the policy pays out. Same age as your mate who didn’t pay. Different outcomes.

Minimum effective dose — practically:

Start with walking if you haven’t. Fix the food. Get the metabolic environment moving. That order still stands. But don’t wait thirteen months to add resistance. Around month three — add three bodyweight sessions a week. Squats, press-ups, lunges. Twenty minutes. That’s enough to keep the factory open.

From month three to six: maintain. Don’t escalate. Consistency beats intensity every time.

From month six: if the bodyweight sessions feel easy, add load. Rucksack with books. Dumbbells. A gym if you want one — but not required.

Track what matters: waist circumference weekly. Strength in your chosen movements monthly. Not just scale weight. The scale lies when body recomposition is happening. The tape measure doesn’t.

Timeline expectations — honest ones:

Four to eight weeks: nervous system adaptation. You’ll get stronger without visible muscle change. That’s normal — it’s the signal before the structure.

Weeks six to twelve: first noticeable changes in how your body feels under load. Lifts feel different. Energy under exertion improves.

Month three: first sensible time for a blood test comparison if you started fasting and food changes simultaneously. Don’t expect dramatic biomarker shifts from resistance training alone in this window — you need more time.

Twelve to fourteen months: that’s when I saw the HDL move. Give it that long before judging the metabolic impact.

Safety note — necessary one:

If you’re on medication for blood sugar, blood pressure, or cholesterol: speak to your GP before adding significant resistance training. Not because it’s dangerous — because it may change your medication needs, and you want that monitored. Fasting changes medication interaction. Resistance training changes body composition and insulin sensitivity. Your GP needs to know what you’re doing so the dosing stays right.

Red flags during lifting: dizziness that doesn’t pass with rest, chest pain, severe headache. Stop. See your GP. Not symptoms to push through.

History of joint problems, back injury, or any other physical limitation: start with bodyweight only and build slowly. The goal is consistency over decades, not performance next month.

CTA + SAFETY (1 minute)

I’ve built a simple tracking template — steps, resistance sessions, waist measurement, and monthly biomarker log. Everything you need to run the before-and-after comparison properly. Link in the description. Free.

And the standard reminder that needs saying every time: this is educational content, not medical advice. Speak to your GP before changing your fasting pattern, diet, or medication. Especially if you’re on diabetes or blood pressure medication. All of my experiments were self-monitored with regular GP reviews, and that’s the right way to do it.
