How This Busy Dad Lost Fat, Built Muscle and Barely Changed Weight in Just 11 Weeks

Body recomposition is widely viewed as the holy grail of physical transformation: losing body fat while simultaneously adding lean muscle.

It’s also often dismissed as either impossible or reserved exclusively for complete beginners. The logic appears fairly convincing. To lose fat, you need to consume fewer calories than you burn. To build muscle, you need enough energy to construct new tissue. One requires a deficit, the other seemingly demands a surplus.

Pick a lane: bulk first, cut later. Right?

Strength and physique coach Gareth Sapstead disagrees. In a detailed breakdown published on his website, Sapstead explains how he helped father and business owner Mark Schadenberg transform his physique ahead of a Men’s Health Netherlands photoshoot – losing fat, adding visible muscle and finishing just 2kg lighter after 11 weeks.

The scales barely budged, but his body changed dramatically.

‘The fitness industry has been telling you to pick one for decades,’ says Sapstead. ‘Bulk first, cut later. Build the muscle, then reveal it.’

Sapstead accepts that fat loss requires an energy deficit, while building muscle requires energy. However, he says the apparent contradiction comes from treating your body like a single energy account.

‘Fat tissue and muscle tissue operate through different pathways,’ he explains. ‘You can be breaking down stored fat for fuel while simultaneously building muscle protein – as long as the conditions for muscle protein synthesis are met.’

Those conditions are relatively straightforward: enough protein and a sufficiently challenging resistance-training stimulus.

Sapstead points towards research examining simultaneous fat loss and muscle gain. According to Sapstead, the phenomenon appeared consistently across the research and wasn’t simply a beginner-only fluke.

He also references studies in which participants consumed between 400 and 800 additional calories each day, all from protein.

By conventional logic, those extra calories should have resulted in weight gain. Instead, Sapstead says the participants either maintained their weight or lost fat while gaining or preserving muscle.

‘Body recomposition is real,’ he concludes. ‘It’s well-supported, and for the right person in the right circumstances, it happens faster than most expect.’

Schadenberg had just 11 weeks to prepare for his photoshoot. He was running a business and raising a family – a familiar combination for many of us – that had gradually pushed training, nutrition and recovery down his list of priorities.

‘He’d let his training slip,’ says Sapstead. ‘Not from a lack of drive, but through the entirely predictable reality of running a business and raising a family.’

His sleep was suffering, his diet lacked structure and he had no consistent exercise routine. Like many men in their late 30s and 40s, Sapstead says, he was also ‘chronically undereating protein’.

That might not sound like an ideal starting point, but it gave Schadenberg several powerful variables to improve almost immediately.

‘Every one of those factors is a recomposition accelerant,’ says Sapstead.

Returning to resistance training after a significant lay-off can produce a response closer to that of a beginner. The stimulus feels novel again, adaptations arrive quickly and previously built muscle may return faster than it took to develop in the first place.

Combine that with more protein, better recovery and structured training, and you can create the conditions to rebuild muscle while using stored body fat to help cover the energy costs.

‘The body has been starved of the right inputs,’ says Sapstead. ‘Give it protein, training and adequate recovery, and it responds.’

After 11 weeks, Schadenberg was only 2kg lighter. But his before-and-after photographs showed considerably more muscle and significantly less body fat.

‘Fat came off. Muscle went on. Bodyweight barely moved,’ says Sapstead.

Sapstead says recomposition is particularly well suited to anyone who has been away from consistent strength training, is carrying more body fat than they would like, habitually eats too little protein or has allowed sleep and recovery to deteriorate.

In other words: most busy men.

For experienced lifters who have trained intelligently, eaten well and slept properly for years, the process is likely to be slower. There’s simply less low-hanging fruit.

For returning lifters, however, they're in a prime position for a recomp.

Avoid Excessive Calorie Deficits AND Surpluses

This isn’t the time for an aggressive diet or an uncontrolled bulk. Sapstead recommends eating around your maintenance calories or slightly above them, with approximately 200 to 300 additional calories coming predominantly from protein.

The aim is to provide enough energy to support training and muscle growth without creating a large surplus that encourages unnecessary fat gain.

Prioritise Protein

Sapstead sets protein at around one gram per pound of bodyweight as a starting point, although higher intakes may also be appropriate.

Protein provides the raw materials required to repair and construct muscle tissue. It is also highly satiating, making it easier to control your overall food intake without constantly feeling hungry.

Lift 3-4 Times per Week

Perform three to four structured resistance-training sessions each week, with a focus on progressive overload.

Your body needs a reason to preserve and build muscle. That means gradually adding weight, completing more reps, improving your range of motion or producing better-quality work – not simply getting hot and tired doing random circuits, or going through the motions with zero intensity.

Stop Judging Progress by the Scales

This may be the hardest part.

When fat is coming off while muscle is being added, your bodyweight may barely change. That doesn’t mean the approach has stopped working. It may mean it’s working exactly as intended.

‘The scale would have told him nothing was happening,’ Sapstead says of Schadenberg’s transformation. ‘The photos would have told him everything.’

Take progress pictures every two to three weeks, track your gym performance and pay attention to how your clothes fit. If your waist is shrinking, your strength is improving and you look more muscular, a stable bodyweight isn’t failure – it’s the holy grail of body recomp in action.
