A free assessment to figure out the best and fastest nutrition protocol for you to achieve your goals:
maximising fat loss and building muscle
Enter your measurements once to get an estimated body fat %, daily calorie and protein targets, and a read on which fat-loss and muscle building strategy actually suits your starting point, built on the same evidence base behind the Fat Loss Sprint.
Hi, I'm Richard, a Performance Nutritionist and Aggressive Dieting Coach. I built this so you can easily figure out how to get the body you want with a clear direction and without confusion.
Worth knowingWeight loss and fat loss aren't the same thing. The scale also carries water, glycogen and gut contents, especially in the first few days of any new protocol. Fat loss, not the number on the scale, is what these targets are built around.
What Clients Say
“I've lost 8 pounds in four weeks, increased the weight I'm lifting across my sessions, and I'm already fitting into my jeans far quicker than I thought I would.” - Zoe Edwards, Fat Loss Sprint client
“His nutrition guidance flexes intelligently between fat loss and muscle gain, with constant motivation, feedback and encouragement.” - Richard Edwards
“I've become stronger, more consistent, and far more confident in my own ability to manage my health and fitness long term.” - Kate Krisztin

What the Colours Mean
The three gauges below all use the same simple system.
| Red | Not the best fit right now, a different approach will serve you better. | |
| Amber | Workable, but expect it to be slower or to take more consistent effort. | |
| Green | A strong fit, a great option to go for. | |
| Gold | An exceptional candidate (Fat Loss Sprint only), the fastest results are realistic here. |
Body Recomposition Likelihood
How realistic it is to lose fat and build muscle at the same time, right now.
The scienceRecomp responds best to higher protein. Research puts the useful range at 2.2–3.5g per kg of bodyweight, and since protein isn't the only macronutrient that matters, 2.2–2.3g/kg is a solid practical target rather than chasing the top of the range. It's also harder the leaner and more advanced you already are, the same "wet towel" effect that makes aggressive dieting tougher at very low body fat. Women using hormonal contraception often get an added edge, since oestrogen itself supports muscle building, so fat can drop while the scale barely moves.
Fat Loss Sprint Suitability
Suitability for an aggressive, short-term fat-loss protocol without sacrificing muscle.
Why aggressive beats "just eat less"Properly structured aggressive dieting sees fewer than 3 in 100 people fail to stick with it, against roughly 1 in 5 on a flat 500-calorie-for-everyone deficit, because the protocol flexes around your hunger and life instead of the other way round. Resistance training at least twice a week is non-negotiable here: skip it and the deficit burns muscle instead of protecting it.
What's a refeed?A short, planned stretch of eating back up near maintenance calories, not a free-for-all binge. The goals: refill depleted muscle glycogen, bring leptin (your hunger hormone) back up so food noise quietens down, restore the background fidgeting and movement (NEAT) your body quietly cuts during a steep deficit, and protect the muscle you're working to keep.
How to refeedEat at roughly maintenance calories for the day(s), built mostly from carbs: about 88% carbs / 9% protein / 3% fat, keeping fat low since it's dietary fat, not carbs, that stores most readily once you're above maintenance. Expect the scale to jump 1–2kg during and just after a refeed; that's water bound to glycogen, not fat, and it settles back down within a few days.
When to refeedTwo solid options, either works well: a single 1-day refeed once a week, or a longer 2-day refeed every 2–3 weeks. Go sooner than planned if food noise and obsessive thoughts about eating start creeping back in, that's your body telling you it's due, regardless of what the calendar says.
This calculator shows a standard deficit above, aimed at around 0.5kg (1lb) of fat loss per week. An actual Aggressive Dieting phase runs a steeper, fully personalised deficit calculated in coaching. This panel shows what to expect from that protocol, not the calorie number itself.
Lean Bulk Suitability
Building muscle first with a small calorie surplus, before worrying about fat loss.
Worth knowingBody Recomp and Lean Bulk can sometimes both come back green for the same person, that's normal, since everyone holds and distributes fat differently. Which route you take from here is genuinely down to personal preference and goals. If you'd like help deciding, apply for 1:1 coaching below.
Real Transformations
All three methods work. It comes down to how quickly you want the results.
Fat Loss Sprint
You'll notice everyone here loses fat at a different rate, that's by design. The Fat Loss Sprint (FLS) is built to maximise fat loss while protecting muscle: the more fat you're carrying, the faster it comes off; the more muscle you're carrying, the more protective the approach has to be. There's no blanket 500–1000 calorie deficit here. It's 100% personalised nutrition.

How To Exercise No Matter The Goal
Whichever route you take (Fat Loss Sprint, Body Recomp or Lean Bulk), strength training is what protects and builds your muscle while these numbers do their work. Skip it and a chunk of any progress on the scale ends up being muscle, not fat.
We've emailed you a science-backed guide to building muscle, referenced straight from PubMed studies, no bro-science or fluff, just the facts you can actually use.

These figures are a starting point. A coaching call turns them into a week-by-week nutrition and training plan.
