A free assessment to figure out which goal is probably best for you: Fat Loss Sprint (aggressive fat loss), Body Recomp (build muscle and drop fat), taking things slow and steady, or a Lean Bulk (gain muscle without gaining excessive fat).
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 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 — 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 500 kcal/day deficit above. 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.
