Strength and muscle growth
The right amount of protein, timing and total energy is key to building muscle you keep. We build a diet that supports your training.
In short
What does muscle growth require from your diet?
Muscle growth requires a small energy surplus, enough protein and good sleep — together with progressive strength training.
Without stimulus you won't grow — without food you can't grow.
The goal is to build muscle with as little unnecessary fat as possible.
Does this sound familiar?
This might sound like your situation
Better recovery, steady strength progression and stable weight over weeks and months.
- You train consistently, but progress has stalled
- You're unsure whether you're eating enough overall
- Protein is randomly spread through the day
- You want to build muscle without unnecessary fat gain
- You take many supplements with little system
SmartEating recommends
What makes the biggest difference?
These are the levers with the biggest impact on visible muscle gain over time.
Protein per meal
Aim for 20–40 g protein at each meal, spread across the day.
Energy surplus size
A small, controlled surplus builds muscle with less added fat.
Training progression
Load must increase over time or the stimulus for growth disappears.
Sleep quality
Most muscle repair and growth hormone release happens during deep sleep.
Carbohydrate intake
Fuels harder sessions and helps you actually finish your training volume.
When should you get help?
Supplements and extreme protocols are often unnecessary — and sometimes unhelpful.
- For very low weight or underweight
- For a previous eating disorder
- For a chronic illness
- For competing in a weight class
- For suspected overtraining
We do not recommend the use of unproven supplements.
Common questions
What people ask us most often.
How much protein is enough?
For most people, 1.6–2.2 g/kg body weight. We tailor it to your situation.
Personal nutrition
No one with strength and muscle growth is exactly the same
Age, everyday life, activity level, other diagnoses and what you actually like to eat determine what works for you.
That's why people with the same starting point need different advice. SmartEating AI learns your situation over time and tailors suggestions to your body, goals and daily life.

SmartEating gives you a meal plan tailored to body weight and training volume.
We set up protein distribution through the day — even on busy days.
A dietitian can fine-tune surplus, timing and periodisation.

The knowledge behind the advice
Protein
Protein is the building block of muscles, skin, enzymes and hormones, and one of the nutrients that gives the most satiety. Most people get enough protein through a varied diet, but needs can shift with age, activity level and life stage.
How much protein do I need?
Most adults need roughly 1.2–1.6 grams of protein per kilogram of body weight per day, depending on age, activity level and goals. If you are older or do a lot of strength training, your needs are likely at the higher end of that range.
Muscle health
Muscles aren't just important for strength and performance — they play a central role in metabolism, balance and independence throughout life. Good muscle health is built over time, through diet and movement together.
