How to set calorie and macro targets for coaching clients

Start with an estimate, then let results correct it

Every method for estimating calorie needs, whether a formula, an online calculator or a multiple of body weight, gives you an approximation. People differ in daily activity, body composition and how accurately they log, so the first number is only a starting point. Treat the first two to three weeks as a calibration period.

A practical approach is to begin from what the client already eats. Ask them to log their normal intake for a week and compare it with their weight trend. If their weight is stable, that intake is close to maintenance, and you can adjust from there with far more confidence than any formula gives you.

Set calories for the client’s goal

Once you have an estimate of maintenance, set calories for the goal. For fat loss, a moderate deficit is usually easier to sustain than an aggressive one, and many coaches aim for a weekly loss of roughly 0.5–1% of body weight. For muscle gain, a small surplus limits unnecessary fat gain, especially for experienced lifters, who gain muscle more slowly.

Whatever the goal, judge the number by the trend over two to three weeks, not by daily readings on the scale. Water, salt, digestion and the menstrual cycle can move scale weight by a kilogram or more from one day to the next. Use a weekly average and adjust in small steps, typically 100–200 kcal at a time.

• Fat loss: a moderate deficit, commonly aiming for about 0.5–1% of body weight per week
• Muscle gain: a small surplus, with slower gains for experienced lifters
• Maintenance or recomposition: calories near maintenance, focus on training and protein
• Adjust in small steps and wait two to three weeks before judging

Setting protein, carbohydrate and fat

Protein is usually set first. For people training for muscle gain, or to keep muscle during a deficit, a commonly used range is around 1.6–2.2 g per kg of body weight per day. For clients with a lot of body fat to lose, many coaches base the number on goal weight or height instead, to avoid unrealistically high targets.

Fat is usually set next, with a floor so the diet stays balanced and satisfying; a commonly used minimum is around 0.6–0.8 g per kg of body weight, or roughly 20–30% of calories. Carbohydrates then fill the remaining calories. Clients who train hard or do a lot of endurance work often do better with more carbohydrate, while others prefer more fat for satiety, and both can work if calories and protein are right.

Round the numbers to something easy to hit. A target of 150 g of protein is easier to aim for than 147 g, and anything more precise is false precision, given how approximate food labels and logging are.

Separate targets for rest days

Some coaches keep the same targets every day, while others lower calories on rest days, usually by cutting carbohydrates, and add them back on training days. Both approaches can work. The main benefit of separate rest-day targets is matching intake to demand, and some clients simply prefer eating more on the days they train.

Keep the weekly total in mind. If rest days drop by 300 kcal and there are three of them, the training days need to go up by a matching 900 kcal across the week, or the weekly average falls. Keep protein the same every day, and introduce rest-day targets only once the client is comfortable hitting a single target consistently.

• Protein: the same every day
• Rest days: fewer carbohydrates, with fat the same or slightly higher
• Check that the weekly average still matches the goal
• Skip it for beginners until one target feels easy

Meal plans or flexible logging

A meal plan tells the client exactly what to eat. It removes decisions, which helps beginners, busy clients and people who want structure, but it can feel rigid and break down at weekends, at family meals or while travelling. Offering two or three alternatives for each meal makes a plan much easier to live with.

Flexible logging gives the client targets and lets them choose their food, as long as the numbers add up. It teaches more and adapts to real life, but it takes more skill and more logging effort. Many coaches start with a plan and move clients towards flexible logging over time, or combine the two: a plan for weekdays and targets for the weekend.

• Meal plan: beginners, busy clients, and anyone who wants to be told what to eat
• Flexible logging: experienced clients who want variety and independence
• Hybrid: planned meals with alternatives, plus targets for the rest

How to review food logs without micromanaging

Look at the week, not at individual meals. Are protein and calories close to target on most days, and where are the misses: weekends, evenings, social events? Patterns tell you what to coach, while a single pizza night does not. Compare the logs with the weight trend and the check-in answers before drawing conclusions.

Pick one thing to improve at a time, and frame it practically: “add a protein source to breakfast” is more useful than “hit your protein”. Praise consistency over perfection. If the logs show a client restricting heavily, skipping meals or becoming anxious about the numbers, ease off tracking and consider whether a referral is needed.

Know when to refer to a doctor or dietitian

A coach’s job is to set sensible targets for healthy adults and help them stick to them, not to diagnose or treat conditions. When a client is under medical care, coaching can work alongside it, within the guidance they receive, but it should never replace it. Refer clients to a doctor or registered dietitian before setting targets if any of the following apply.

• Medical conditions such as diabetes, or kidney, heart or thyroid disease
• A current or past eating disorder, or signs of disordered eating
• Pregnancy or breastfeeding
• Medication that affects appetite, weight or blood sugar
• Minors, or rapid weight change with no clear explanation
• Anyone whose doctor has given them specific dietary instructions
