Eat Well, Train: a beginner's guide + a week of food

No mysticism, no superfoods, no "what our ancestors ate." Just what the evidence actually supports — followed by a full 7-day plan built for cooking for one, in the UK, on a budget. Adherence beats optimisation.

Educational guide, not medical advice. Numbers are sensible defaults, not prescriptions — adjust to your own body and use the calculator.

01Principles

Ten things that are true and useful. Most diet advice is a re-skin of these.

AYou're a generalist omnivore

Humans have no single "ancestral diet." Groups thrived on radically different foods — high-meat Arctic, high-starch tropical, dairy-heavy pastoralist.

The real adaptation is dietary flexibility plus cooking, which unlocked far more calories from the same food. "What are we built for?" gives almost no prescriptive guidance — it tells you that you can eat well in many patterns, not which one to pick.

BEnergy balance sets bodyweight

Calories in vs. out decides whether you gain, lose, or hold weight. Full stop.

Everything else — macros, food choices, timing — is about body composition and health, not the number on the scale. No food is inherently "fattening" outside its calories.

CProtein: ~1.6 g/kg/day

Aim for roughly 1.6 g per kg of bodyweight per day, spread across your meals (≈3–4 servings of 0.3–0.4 g/kg).

Going above 2.2 g/kg adds nothing extra for muscle. More protein isn't better past that — it just displaces other food. A 75 kg person → ~120 g/day.

DFibre: 30 g+ per day

Target 30 g of fibre daily — most people get half that.

It comes free with whole foods: oats, beans, lentils, wholemeal bread/pasta, fruit, veg, nuts. Good for gut health, satiety and long-term disease risk.

EMinimise ultra-processed food

The strongest single dietary lever. It's not "sugar" per se that's the villain.

It's that the processing itself drives overconsumption — engineered to be soft, calorie-dense and hyper-palatable, so you eat more before feeling full. Cook from recognisable ingredients and most problems shrink.

FFats: include them, bias unsaturated

Fat is essential — don't fear it. Bias toward unsaturated (olive oil, nuts, seeds, avocado, oily fish).

Eat oily fish 1–2× per week (sardines, mackerel, salmon) for omega-3s. Tinned counts and is cheap.

GWhole-food carbs aren't the problem

Rice, oats, potatoes, fruit, bread — not the cause of fat gain. They're practical, cheap fuel, especially around training.

The issue is rarely "carbs"; it's total calories and ultra-processed forms. Eat the potato.

HMediterranean = best long-term data

The eating pattern with the strongest long-term health outcomes.

But it isn't magic — it's just everything above wearing a cuisine: veg, legumes, whole grains, olive oil, fish, some dairy, little ultra-processed food. A template, not a rulebook.

IBeginners: recomp, don't bulk/cut

As a beginner you can build muscle and lose fat at the same time (body recomposition).

Recipe: eat near maintenance calories, hit your protein target, and lift progressively (add reps/weight over time). No need to bulk or cut yet — that's an advanced-lifter problem.

JSupplements: a very short list

Almost all are a waste. The two with real support:

CREATINE monohydrate, 3–5 g/day, every day.
VITAMIN D Oct–March at UK latitudes (no sun-made D).

SKIP BCAAs, fat burners, test boosters. MEH whey = convenience only, not magic.

Supplements, spelled out

TAKE
Creatine monohydrate — 3–5 g/day Most-studied, cheapest effective supplement. Small strength/muscle benefit. No need to "load" or cycle. Take any time, every day. ~£10 buys months.
TAKE
Vitamin D — 10 µg (400 IU)+ Oct–March At UK latitudes your skin makes ~none in winter. NHS advice for everyone. Cheap. Year-round if you're indoors a lot.
OPTIONAL
Whey protein — convenience only Just cheap, fast protein powder. Useful if you struggle to hit your target, otherwise unnecessary. Food works just as well.
SKIP
BCAAs, fat burners, test boosters BCAAs are pointless if you eat enough protein. Fat burners are caffeine + hope. Test boosters don't. Save your money.

02Protein & calorie calculator

Numbers update as you type. Defaults are set for a 75 kg male so it's useful before you touch anything. The meal plan below is built around roughly these figures.

Daily protein target
1.6 g × bodyweight
Maintenance calories
Mifflin-St Jeor × activity (TDEE)
Target calories
Protein spread
across ~4 meals/snacks

Estimates only. Real maintenance can vary ±15% between people of the same stats — track your weight over 2–3 weeks and adjust calories if it's not moving the way you want. Don't chase precision the equations can't give you.

03The 7-day meal plan

Built for one person, batch-cooked, UK-budget. Calibrated for a ~75 kg person → ~120 g protein and ~2,200–2,400 kcal maintenance (a lightly-active recomp). REHEAT marks meals reheated from a batch cook — most of your "cooking" is microwaving leftovers.

Scaling: these quantities suit ~75 kg. Lighter? Trim portions / drop a snack. Heavier or hungrier? Add a snack or scale carbs up. Use the calculator for your real protein and calorie targets, then nudge portion sizes to match — the food choices stay the same.

The meal template (so you can improvise)

Once the week clicks, you don't need a plan — you need a shape. Every main meal is:

SlotPick oneWhy
Protein
palm-sized+
chicken thighs · mince · tinned fish · eggs · lentils/beans · Greek yogurt · wheyHits your 1.6 g/kg target and keeps you full.
Veg
half the plate
frozen broccoli/peas/mixed · any salad · tinned tomatoes · onion & garlic baseFibre + micronutrients + volume for few calories. Frozen is as nutritious and cheaper.

Flavour
swap for variety
chilli/cumin → Mexican · curry powder → Indian · soy/ginger → Asian · oregano/garlic → ItalianSame base ingredients, different cuisine. This is how one batch cook feels like five meals.

Swap the protein and the spice and a chicken-rice-veg bowl becomes a stir-fry, a curry, a burrito bowl, or an Italian traybake. Variety is a seasoning problem, not a shopping problem.

05Weekly shopping list

One week, one person, everything above. Prices are approximate UK supermarket estimates (mid-range own-brand, 2026) — they'll vary by shop, offers and region. Buy spices/oil/condiments once and they last weeks, so real weekly spend is lower than the headline after the first shop.

Reading the total: the table lists full pack prices. In practice you only buy oil, spices, peanut butter, nuts, honey, chocolate and condiments occasionally — strip those and a typical ongoing week is ≈ £34–42 for ~2,300 kcal/day at ~120 g protein. Cheaper still if you swap some beef mince for lentils/eggs. All figures approximate.
