Fat loss that lasts
Intelligent, measured fat loss built around your life: no gimmicks, no extreme restriction, and a result you are still holding in two years.
Overview
How does sustainable fat loss actually work?
Leigh states the position plainly on his own site: intelligent, effective fat loss tailored to your lifestyle, with no gimmicks and no extreme restrictions, driven by data and precise coaching. The interesting question was never how to lose fat quickly. It is how to lose it and still be there in two years.
That changes the design. Intake is set at a deficit you could actually maintain through a working month, protein is held high enough to protect lean mass, and strength training continues throughout so what you lose is fat rather than muscle. Aerobic work is dosed rather than piled on.
It also changes how progress is judged. Bodyweight alone hides the change that matters, so where diagnostics are part of the programme a DEXA scan separates fat mass from lean mass properly. Otherwise the measures agreed at the baseline assessment do the job.
The benefits of a measured approach to fat loss
You keep the muscle
Strength training and adequate protein through the deficit mean the loss comes from fat rather than from lean mass. That is what changes shape, and it is what protects your metabolic rate on the way down.
It survives a normal month
Built around travel, dinners out and late finishes from the start, the plan holds through the weeks that break most diets. The test applied is simply whether you could still be doing it in two years.
Progress you can trust
Measured properly, a fortnight where the scales did not move can still be a fortnight of real progress. Separating fat mass from lean mass stops good work being abandoned for looking like failure.
Health markers move with it
Reducing fat mass, particularly around the middle, is widely associated with better metabolic markers. Where diagnostics are part of your programme, that improvement is something you can see in the numbers.
What gets in the way
Why fat loss stalls or reverses
- A deficit set so aggressively that nobody could hold it past a few weeks
- Strength training dropped during a diet, so muscle is lost alongside fat
- Protein too low to protect lean mass while intake is reduced
- A plan that assumes no travel, no client dinners and no late finishes
- Progress judged on bodyweight, so a good week can look like a failure
- Repeated cycles of restriction and rebound, each one starting from a worse position
How it works
How W1 Performance approaches fat loss
Nutrition Strategy
Included in every programmeA weekly strategy rather than a meal plan, with protein and intake set against your training, and practical rules for restaurants, hotels and airports.
See treatment detail →1-to-1 Personal Coaching
From £1,200 per monthStrength work maintained throughout, which is what makes the weight you lose fat rather than muscle, coached so load stays productive in a deficit.
See treatment detail →Recovery, Sleep & Stress Coaching
Included in every programmeShort sleep and sustained pressure both work against fat loss through appetite and recovery. Addressing them is often what unsticks a stalled plan.

Frequently asked
questions
How fast should I expect to lose fat?
Slower than most plans promise and more durably. Leigh frames the timescale as twelve weeks to feel a meaningful shift and six to twelve months to genuinely change. A rate you can hold through a demanding month beats a faster one you abandon, because the second one reverses.
Do I need to give up alcohol?
No, though where it sits and how much there is get planned rather than ignored. A strategy that only works in weeks with nothing social in them is not a strategy for the life you have. We set what a normal week absorbs and how to handle a heavy one.
Why keep lifting weights while trying to lose fat?
Because it decides what you lose. In a deficit without strength training, a meaningful share of the loss comes from muscle, which changes your shape for the worse and lowers what you can eat later. Lifting through the deficit keeps the loss where you want it.
