A beginner meal plan built on four numbers
By Chris Mann Dip.IOPN, Sports nutritionist and personal trainerChecked against published guidance 7 min read
This is for someone who has started training in the gym and wants to eat in a way that supports building muscle. You do not need a diet with a name. Set your energy target, hit your protein, eat enough carbohydrate to train well, and keep meals repeatable enough that you do not have to think about them. Here is how to work out your numbers, what a practical day of food looks like, and the portion cues to use when you have not weighed anything.
In short
A beginner meal plan for building muscle rests on a few numbers: an estimated daily energy target, protein of about 1.6 g per kilogram of bodyweight, enough carbohydrate to train well, and fat at roughly a quarter to a third of your calories. Build three or four repeatable meals that hit those numbers using food you already like.
- Estimate energy from bodyweight, then adjust from your real weekly weight trend rather than a calculator.
- Total energy intake influences whether your bodyweight rises, while adequate protein and progressive resistance training help support muscle gain. Carbohydrate and fat also matter for training, recovery and making the diet workable.
- Change your food by no more than one meal at a time — repeatable beats perfect.
- Use hand and plate portion cues when you have not weighed anything.
Before you start
This is general fitness and nutrition guidance for healthy adults aged 18 and over, not medical advice. Speak to a health professional first if you are pregnant or recently gave birth, recovering from surgery, injury or illness, taking medication, living with a heart, lung, metabolic or joint condition, or have a history of disordered eating.
If food or weight has stopped feeling straightforward
Targets and numbers help most people, but not everyone, and not at every point in their life. If counting food, weighing yourself or thinking about your body has become distressing or hard to control, put the numbers down and speak to someone: in the UK, Beat runs a helpline on 0808 801 0677 and your GP can help. If you cannot gain or lose weight despite genuinely changing what you eat over a couple of months, that is also worth a GP appointment rather than a stricter plan. This page is general information for healthy adults 18 and over, not medical advice.
How to set your calorie and protein targets
1. Estimate your daily energy need
The quickest rough sum is bodyweight in kilograms multiplied by about 22 for a resting figure, then by roughly 1.4 if you are mostly sitting and training two or three times a week, or 1.6 if you are on your feet most days. Treat those numbers as a back-of-envelope heuristic rather than a published equation: the calorie calculator uses the Mifflin-St Jeor equation with your own details and is a better starting point. Either way, the figure is an estimate you adjust from your real weekly weight trend.
2. Decide the direction, gently
To lose fat, a common starting point is taking around 15 per cent off that figure. To gain muscle as a beginner, add around 10 to 15 per cent. Neither adjustment is an established optimum, and a percentage of your own estimate is not interchangeable with a fixed number of calories for everybody. Sharper changes tend to cost sleep, training quality and consistency without speeding much up, so start conservatively and let two to three weeks of weight data correct the figure.
3. Set protein first
Aim for 1.6 to 2.2 grams of protein per kilogram of bodyweight, towards the higher end if you are eating less to lose fat (NHS, 2022) (British Nutrition Foundation, no date) (Morton et al., 2018). The evidence puts the point where extra protein stops helping at about 1.6 g/kg, and 2.2 g/kg is the cautious top of the uncertainty around that estimate rather than a better dose. Protein is the target worth being consistent with, though it only does its job when your total energy is high enough as well.
4. Fill the rest with carbohydrate and fat you enjoy
A practical starting split is fat at roughly a quarter to a third of your calories, with carbohydrate taking the remainder according to your training and what you enjoy eating. There is no exact carbohydrate target required for muscle growth, and no evidence that a specific gram-per-kilogram fat figure is needed "for hormones" in healthy adults eating enough overall. Carbohydrate does fuel your sets, so it is not the thing to cut on training days.
To put a real number on your energy target for gaining, use calorie calculator.
For your protein target in grams, use protein calculator.
A simple day of meals
This day lands at roughly 130 grams of protein — a sensible target for someone around 70 kg. Scale the carbohydrate portions up or down to match your energy target.
| Meal | Example | Protein |
|---|---|---|
| Breakfast | Greek yoghurt with oats, berries and a spoon of peanut butter | ~30 g protein |
| Lunch | Chicken or tofu wrap with salad, plus a piece of fruit | ~35 g protein |
| Snack | Cottage cheese or a protein shake with a banana | ~25 g protein |
| Dinner | Salmon, mince or lentils with rice or potatoes and two veg | ~40 g protein |
Protein in common foods
Figures are approximate and rounded, based on typical cooked portions.
| Food | Portion | Protein |
|---|---|---|
| Chicken breast, cooked | 150 g | 45 g |
| Salmon fillet, cooked | 140 g | 35 g |
| Lean beef mince, 5% fat, cooked | 150 g | 39 g |
| Greek yoghurt, 0% fat | 200 g | 20 g |
| Eggs | 2 large | 13 g |
| Cottage cheese | 200 g | 22 g |
| Firm tofu | 200 g | 24 g |
| Red lentils, cooked | 200 g | 18 g |
| Semi-skimmed milk | 300 ml | 10 g |
| Whey protein powder | 1 scoop (30 g) | 24 g |
Food supports training, so pair this with beginner gym workout plan.
If eating this much feels like hard work, read small appetite.
Portion cues when you are not weighing food
- Protein
- A palm-sized piece at each main meal
- Carbohydrate
- A cupped-handful of rice, pasta or potatoes, more on training days
- Vegetables
- Two fist-sized portions at lunch and dinner
- Fats
- A thumb-sized portion of oil, nuts, cheese or nut butter per meal
Beginner nutrition questions, answered
- How many calories should a beginner eat?
- As a rough heuristic, estimate your resting need as bodyweight in kilograms times about 22, multiply by 1.4 to 1.6 for daily activity, then adjust by around 15 per cent down to lose fat or 10 to 15 per cent up to gain muscle. A calculator using the Mifflin-St Jeor equation gives a better starting estimate. Track your weekly average bodyweight for two to three weeks and change the figure only if the trend is not going where you want.
- How much protein does a beginner need to build muscle?
- Between 1.6 and 2.2 grams per kilogram of bodyweight a day is the range supported by the research for people doing resistance training, where 1.6 g/kg is the estimated point at which more protein stopped adding anything and 2.2 g/kg is the cautious upper edge of that estimate (Morton et al., 2018). Someone at 70 kg would aim for roughly 112 to 154 grams, spread across three or four meals.
- Do I need to count every calorie?
- No. Most beginners do better hitting a protein target, keeping meal structure consistent and using hand portions, then checking weekly weight trends (Public Health England, 2021). Detailed logging is a tool for when the trend stalls, not a permanent requirement.
- Should I eat before or after training?
- Both work. Have a meal containing carbohydrate and protein within a few hours either side of your session. If you train early, a small snack such as yoghurt and fruit beforehand is usually enough.
- Do I need protein shakes?
- No. They are convenient, not magic. If you reach your protein target from meals, a shake adds nothing, and if you struggle to, it is a cheap and easy way to close the gap.
- Can I still eat takeaways and sweets?
- Yes. Meeting your protein target and your overall energy total matters far more than avoiding any single food. Leaving room for meals you enjoy is what makes a plan last past week three.
- How fast should I lose weight as a beginner?
- Around 0.5 to 1 per cent of bodyweight a week is sustainable. Faster than that while learning to train usually means worse sessions, more muscle lost and a plan you abandon.
