A 12-week strength and protein programme for building muscle and losing fat
Anyone can lose weight. The part worth keeping is the muscle. Most fat-loss plans cost you muscle, and after 40 you cannot spare it, because muscle is the tissue that keeps you strong, mobile and independent in the decades ahead. This is the plan for losing fat and building strength at the same time, a sustainable deficit, enough protein, and progressive strength training, written for adults in their 40s and beyond.

The short version
What you get
Why start today
Muscle leaves steadily from around 40, and a careless diet speeds it up. Every week you cut hard without resistance training and enough protein is lean mass you may not get back. The sooner you train while you lose fat, the more of the right tissue you keep. Launch pricing is held for the first 50 buyers.
What it costs
One payment, from SGD 99, yours for life. Less than the cost of a single personal-training session, and a fraction of a month of generic app subscriptions you would otherwise stack. No subscription, no upsell.
Get the Protocol, from SGD 99→The problem nobody packages for
The scale rewards weight lost. It does not tell you whether you lost fat or muscle.
Crash diets and endless cardio do move the number on the scale. The trouble is what kind of weight leaves. Eat far too little, skip the lifting, and a meaningful share of the loss is muscle, not fat. You get lighter, and quietly weaker, at the same time.
That matters more after 40 than at any point before it. From around 40 you lose muscle steadily, about 8% a decade, and faster later on. Run a careless diet on top of that and you draw the account down quickly. Muscle is not about looks. It is the tissue that keeps you strong, supports your bones, helps your body handle glucose, and lets you stay independent through your later decades. Lose it and you erode the very thing the diet was meant to protect.
The fix is not exotic, and it is not a crash. The research names the same three levers every time: a modest, sustainable deficit, enough protein, and progressive strength training. The deficit takes the fat off. The training and the protein are the signal and the raw material that tell your body to keep, and build, the muscle. That is the entire job of this Protocol, written so you can run it on your own.
What you get
01
Three phases of four weeks: Foundation, Build, Consolidate. Two to three short strength sessions a week, built from compound patterns (squat, hinge, push, pull, loaded carry), with week-by-week loading and a defined endpoint. Three equipment tracks ship in the box, home, dumbbell-only, and full gym, so the same programme runs wherever you train. Form is earned before load is added.
02
A protein and energy-balance system you can actually run. A realistic gram-per-kilogram floor, the eat-protein-first tactic, and meal-by-meal scaffolding for a modest, sustainable deficit when you are losing fat, or a slight surplus when you are building muscle. It comes with a mini cookbook of high-protein, Singapore-friendly recipes, and a recipe and meal-planner spreadsheet, so the target turns into food you would actually cook.
03
How to keep the programme moving through the weeks real life throws at it: travel, a missed session, poor sleep, a busy stretch at work. How to scale a session rather than abandon it, where the non-negotiables sit, and how to protect the week as a whole rather than chasing a perfect one. Consistency over twelve weeks is what builds the body, not any single heroic session.
04
Score your own healthspan at home, in week 0 and again in week 12. A self-baseline and a re-check across the measures you can take without a studio scan: weight trend, waist-to-height ratio, and a simple strength self-test. Strength holding or rising while the waist comes down is the at-home signal that the weight leaving is fat, not muscle. It points you toward the two pillars a home programme cannot fully measure.
05
The programme does not leave you at the finish line. A maintenance plan for holding the body composition you built, and a clear next training block so the strength keeps climbing rather than drifting back. How to set a deficit for more fat loss, or a slight surplus to add muscle, and how to know which you should be running next.
06
The full evidence base, referenced so a doctor, a scientist, or a sceptical family member would nod: the recomposition evidence, the lean-mass-sparing research, why the deficit must be modest, the protein numbers, and the honest limitations. Your access does not expire, and updates land as the research moves.
A look inside, Foundation week 1
Full body, three sessions, built from compound patterns. Reps sit in the strength-relevant 6 to 10 band, the descent is controlled, and you leave two to three reps in reserve. You add load only when you own the top of the rep range with clean form. This is one sample week; the programme progresses it across twelve.
Session A
Lower-body lead
Control the descent, leave 2 to 3 reps in reserve
Hips back, flat back, feel the hamstrings load
Three seconds down, one second up
Tall and braced, walk at an even pace
Session B
Upper-body lead
Ribs down, press without arching the lower back
Lead with the elbows, pause at the bottom
Chest up, knees track over the toes
Breathe, keep the ribs and pelvis stacked
Session C
Full body
Own the depth you can control with clean form
Squeeze the shoulder blades, no momentum
Drive through the heel, no push off the trailing foot
Resist the twist, brace through the whole set
The book edition
The whole Protocol comes two ways: an online member area you train from on your phone, and a designed PDF book you keep and read away from a screen. Same content, yours for life. Here is a taste of the writing.
Anyone can lose weight. The part worth keeping is the muscle. Train hard enough to keep it, eat enough protein to rebuild it, and the weight that leaves is the weight you do not need.
The full designed book ships with your purchase, alongside the online member area.
Built on the evidence, not on hype
About 8% a decade
is the muscle most adults lose from around 40, and faster later on. A fast, careless diet on top of that runs the account down quickly. Training while you lose fat is how you keep the weight that leaves the weight you do not need.
Asian Working Group for Sarcopenia, J Am Med Dir Assoc, 20205% versus 2%
is the lean-mass loss in older adults who dieted with cardio alone against those who added resistance training, at a matched 9% weight loss. Lifting is the signal that tells the body to keep the muscle a diet would otherwise shed.
Villareal et al., N Engl J Med, 2017Around 1.6 g per kg
of protein a day is the point that maximises lean-mass gains from training, with little extra past 2.2 g/kg. In a deficit the target sits higher, because protein is doing double duty. The Protein Playbook turns that into food.
Morton et al., Br J Sports Med, 2018About 16% per 5 kg
is the higher risk of death from any cause carried by every 5 kg of lower grip strength, across nearly 140,000 adults in 17 countries, a stronger signal than blood pressure. Strength is the currency of the decades ahead.

| Built for the 40s and beyond | Yes, designed around the muscle you cannot afford to lose after 40 | Rarely; most assume a younger, well-recovered body | Rarely; generic targets assume a general user | Not addressed |
| Progressive structure | 12 weeks of week-by-week loading with a defined endpoint | Often a one-off plan with no progression built in | Often a content playlist, not a progression | None |
| Protein and a sustainable deficit | A protein system plus a modest deficit or lean-gain surplus you can actually hold | Usually a workout only, with nutrition left to you | Generic calorie targets, rarely protein-led | Often a steep cut that costs muscle, not fat |
| At-home healthspan checkpoint | A week-0 and week-12 4-Pillar Checkpoint you score yourself | None | A weight or step count, not a healthspan read | The scale only, which rewards weight lost, not body changed |
| Medical review | Medically reviewed by an MBBS-qualified co-founder | Varies, often none | Varies, often none | None |

Questions, answered straight
Because most plans cut too hard and train too little, so the weight that comes off is partly muscle, and a deep, prolonged deficit pushes your metabolism down in ways that outlast the diet. If you lost weight before and watched it come back, that was not you failing, it was your body doing what a crash trains it to do. The Protocol runs a modest deficit, a few hundred calories a day, with resistance training and enough protein, so you lose fat steadily while keeping the muscle. Then it hands you a maintenance plan for after the twelve weeks, which is where most people come undone.
No. You build lean, usable strength, not size you did not train for. Building noticeable muscle takes years of deliberate, heavy, high-volume work and a real surplus of food. On a modest deficit, or at maintenance, what this programme adds is strength, density and shape, the muscle that keeps you strong and independent, not a different physique you have to chase. You will most likely look leaner and more defined, not larger.
No. The programme is beginner-first: you earn clean form at each movement pattern before any load is added, and every exercise carries an easier regression for the days a movement is too hard. Two to three short sessions a week is the whole ask, and three equipment tracks mean you can run it at home with almost nothing, with a pair of dumbbells, or in a full gym.
No. You cut for fat loss and eat at maintenance, or a slight surplus, to build muscle, and the Protocol shows you how to set each. We also build in planned stretches back at maintenance, because a non-stop deficit is exactly what stalls progress and provokes regain. You are not signing up to eat less forever. You are learning to steer your own energy balance for the rest of your life.
Yes, especially if you are newer to training or carrying some fat to lose. Building muscle while losing fat in the same window runs on two levers, progressive resistance training and a higher-protein diet, and the evidence is strongest for exactly the people most likely to start here. The honest limit: the leaner and more trained you already are, the harder it gets to do both at once. If that is you, expect to lose fat while keeping the muscle you have and adding strength. Either way, you finish better composed than you started.
No. The Protocol is an educational training and nutrition programme, not medical advice, a diagnosis, or a treatment. Catalyst is a personal training studio, not a medical provider. If you have a heart, joint, metabolic or other medical condition, or you are returning to training after a long break, speak to your doctor before you start. If you have any kidney concern, set your protein target with your doctor or dietitian first.
Yes. The Protocol is fully digital and self-guided, so it works wherever you are, and the three equipment tracks mean it adapts to the gym you actually have. If you want the same discipline coached anywhere in the world, Catalyst Online Coaching is the next step up. If you are in Singapore and want it coached in studio, the complimentary 30-min consultation is the place to start.
The Protocol plus Coach Check tier includes everything in the Protocol, plus a one-time form review of your three main lifts by a Catalyst coach and personalised protein and calorie targets. It is the option for anyone who wants a human set of eyes on their technique before they load up.
No, and there is a fair reason. The Protocol unlocks in full the instant you buy, the book and the trackers included, so there is nothing to return. That is why the full cited evidence and a sample of the writing sit on this page: you can judge the depth and the voice before you pay a cent. Once you are in, it is yours to keep for life, with every future update.

Important
The Muscle + Fat Loss Protocol is an educational training and nutrition programme. It is not medical advice, a diagnosis, or a treatment, and it is not a substitute for care from a qualified medical professional. Catalyst Performance is a personal training studio, not a medical provider.
Speak to your doctor before starting a new training or nutrition programme, especially if you have a heart, joint, metabolic or other medical condition, or you are returning to training after a long break. Speak to a doctor or dietitian before changing your protein intake if you have a kidney condition, and manage any diagnosed condition with your own doctor. Individual results vary, and no specific outcome is promised.
