Should a beginner start with diet or exercise first?

Start both in the same week, but only change one at a time afterwards. Trying to overhaul every meal and every habit at once is the most common reason a first month collapses.

How much should a beginner eat to build muscle and lose fat at the same time?

Around maintenance calories with protein at the top of the range. Beginners can build muscle and lose fat simultaneously for a while, and eating at maintenance gives you the best shot at both.

How long before a diet and exercise plan shows results?

Strength usually improves within two to three weeks. Visible changes typically take two to three months of consistent training and eating, and show up in photographs before they show on the scales.

Do I need to count calories as a beginner?

Not forever, but counting for two to four weeks is the fastest way to learn what your usual intake actually is. Most people are surprised in one direction or the other.

What if I miss a training session or a whole week?

Pick the plan back up where you left it and use the same weights as your last completed session. Nothing meaningful is lost in a week, and restarting from scratch is unnecessary.

A diet and exercise plan for your first month

By Chris Mann Dip.IOPN, Sports nutritionist and personal trainerChecked against published guidance 15 August 20268 min read

In short

For a first month, train three times a week with full-body sessions, eat around 1.6 to 2.2 grams of protein per kilogram of bodyweight a day, and set calories at roughly maintenance plus 10 per cent if you want to gain or maintenance if you want to recomposition. Keep the same plan for four weeks before changing anything.

Three full-body sessions a week, six exercises each
Protein: 1.6–2.2g per kilogram of bodyweight a day
Calories: maintenance for recomposition, +10 per cent to gain
Change one thing at a time, and only after four weeks

Training and eating are usually written about separately, which is why so many beginners do one of them properly and the other by accident. This is general guidance for healthy adults aged 18 and over: one month, three sessions a week, and four food numbers that sit alongside them.

Why the two halves belong in one plan

Training is the signal to build; food is the material to build with. Train hard on too little food and you get tired rather than bigger. Eat plenty without training and the extra mostly goes on as fat. The plan below runs both at once, which is why it works when either half alone does not.

What each half is responsible for
Half of the plan	What it does	What it cannot do
Training	Tells the body which tissue to keep and build	Create the material to build with
Nutrition	Supplies protein and energy for the rebuild	Decide where the material goes

What the evidence says

Protein intake around 1.6g/kg supports muscle gain during resistance training
A meta-analysis of protein supplementation studies found gains in lean mass increased with intake up to approximately 1.6 grams per kilogram of bodyweight per day, with little added benefit above that in most people.

The training month

Three full-body sessions with a day between them. Same six movements every session, two to three sets of eight to twelve reps, stopping each set with a few reps in reserve.

Week by week
Week	Sessions	What changes
1	3	Find your starting weights. Record everything.
2	3	Add a rep wherever last week felt easy.
3	3	Add the smallest weight increment where you hit 12 reps.
4	3	Add a third set to the squat, push and pull.

Four numbers to eat to

Four numbers cover everything a beginner needs. Work out protein first, because it is the one most people are short on, then energy, then let fat and carbohydrate fill the rest.

Work out your daily protein target

Your bodyweight

Measured in

Meals a day

120g to 165g of protein a day

That is roughly 30g to 41g per meal across 4 meals. If you are new to training, start near the lower figure; if you have been lifting consistently for a while, work towards the higher one.

Based on the widely used 1.6 to 2.2g per kilogram of bodyweight range for people doing resistance training. It is a general estimate for healthy adults, not personal or medical advice. Nothing you type here is saved or sent anywhere.

Protein: 1.6 to 2.2 grams per kilogram of bodyweight, spread across three or four meals.
Energy: maintenance calories if you want to change shape at your current weight; maintenance plus about 10 per cent if you want to gain.
Fat: roughly 0.8 to 1 gram per kilogram of bodyweight, for hormones and for food that is actually pleasant to eat.
Fibre: 30g a day, which the NHS recommends for adults and which almost nobody hits without trying.

Weigh yourself weekly, not daily

Bodyweight moves by a kilogram or more day to day from water and food in the gut. A weekly average, or the app's trend line, is what tells you whether the plan is working.

What a day actually looks like

Numbers are easier to hit when they are attached to meals. This is one ordinary day for a 75kg beginner aiming at roughly 135g of protein — not a prescription, just a shape to copy.

One day, roughly 135g protein
Meal	Example	Protein
Breakfast	Greek yoghurt, oats, berries	~30g
Lunch	Chicken, rice, vegetables	~40g
Snack	Milk and a handful of nuts, or a shake	~20g
Dinner	Salmon or mince, potatoes, salad	~45g

What the evidence says

Spreading protein across the day is a reasonable default
Reviews of protein distribution suggest that dividing intake into three or four servings across the day is at least as effective as concentrating it in one or two meals, and it is usually easier to eat that way.

What to change after four weeks

At the end of week four, look at two things: the weights in your log and the trend in your bodyweight. Change one variable based on what you see, then run another four weeks.

Reading your first month
What you see	What to change
Weights up, bodyweight steady	Nothing. This is going well.
Weights up, bodyweight falling	Add around 200 calories a day.
Weights flat, bodyweight rising fast	Hold calories; check sleep and session effort.
Weights flat, protein under target	Fix protein first, before touching anything else.

This is general guidance, not medical advice

If you are pregnant, managing a health condition, taking medication or have a history of disordered eating, speak to a healthcare professional before changing how you train or eat.
