Body recomposition is the idea of losing fat and building muscle at the same time, instead of doing it in turns the way the classic bulk-and-cut playbook prescribes. It sounds too good to be true, which is why half the internet treats it as a myth. The reality is more interesting: it's possible, it's documented, but it doesn't work the same for everyone and it isn't fast. Here's who it works for, who it barely works for, and how to set up the plan so it actually happens.
If you've just read our guides on macros for cutting and macros for bulking, think of recomposition as the middle ground between them: no aggressive deficit to shred, no clear surplus to grow. It's the band in the center, and that's exactly why it demands more precision.
Is body recomposition possible?
Quick answer: Yes, body recomposition is possible: the body can use stored fat as fuel to build muscle under the right conditions. It works best in beginners, in people returning after a break, in those with a high body-fat percentage and in untrained individuals. In advanced, very lean athletes it is far slower.
Body fat is stored energy. When you train with enough of a stimulus and eat plenty of protein, your body has a reason to build muscle tissue and, at the same time, an internal fuel source to do it. That's the physiological basis of recomposition. A broad review on the topic concluded that gaining muscle and losing fat simultaneously is not only possible but happens regularly in specific populations (Strength & Conditioning Journal, 2020).
Who it works best for
- Beginners: the nervous and muscular system responds strongly to any new stimulus. So-called "newbie gains" are real and let you build muscle even in a slight deficit.
- People returning after a break: the "muscle memory" effect makes regaining lost mass faster than building it the first time, because the nuclei in muscle fibers persist.
- People with a high body-fat percentage: the more fat reserves you carry, the easier it is for the body to draw on them while building muscle.
- Untrained individuals: if you ate little protein, slept poorly or trained without progression, fixing those variables opens a wide window for simultaneous improvement.
Who it's very slow for
If you've trained seriously for years and you're already lean, the story changes. Your body is near its natural muscle ceiling and has little fat to spare. Recomposition is still possible, but the pace is so slow that alternating bulking and cutting phases often gets you there faster. Honesty first: it's not magic, and for the lean advanced lifter it's usually not the most efficient route.
The 5 levers of recomposition
Quick answer: Body recomposition rests on five levers: high protein (1.6-2.2+ g/kg/day), strength training with progressive overload, a calorie balance at maintenance or a slight deficit, 7-9 hours of sleep with stress management, and consistency over 12 weeks or more. Failing on one drags down the rest.
1. High protein
This is lever number one. Protein supplies the amino acids that build muscle and also protects lean mass when calories are low. The supported range for people who train sits between 1.6 and 2.2 grams per kilo of body weight per day, and pushing toward the high end makes sense in recomposition because you eat few calories for the work you do (Journal of the International Society of Sports Nutrition, 2018). For a deeper look, see our guide on how much protein you need per day.
2. Progressive strength training
No stimulus, no signal to build. Strength training is what tells your body "this muscle is needed, don't waste it." The key is progressive overload: adding weight, reps or sets over time. If you do the same thing every week, your body has no reason to adapt. Two to four strength sessions a week, built around the major movement patterns, support a well-run recomposition.
3. Calorie balance at maintenance or a slight deficit
Here's the nuance that separates recomposition from cutting. You don't want an aggressive deficit: cut too hard and the body prioritizes survival over building, and muscle suffers. The sweet spot is eating around your maintenance level or in a slight deficit, leaving room for muscle protein synthesis to happen. Some run it with "cycling": a slight surplus on hard training days, a slight deficit on rest days.
4. Sleep and stress management
Muscle isn't built in the gym, it's built while you rest. Sleeping 7 to 9 hours regulates the hormones that govern muscle growth and recovery. Insufficient sleep raises cortisol, worsens recovery and sabotages progress even when diet and training are perfect. It's the cheapest lever and the one most people ignore.
5. Consistency over 12 weeks or more
Recomposition is slow by definition: two opposite things happening at once. Don't expect dramatic changes in four weeks. Think in blocks of 12 weeks minimum and measure by trends, not by a single day's reading. The people who quit usually do so right before results start to show.

How to set your macros for recomposition
Quick answer: To set your recomposition macros, calculate your maintenance calories and eat them as-is or with a slight 200-300 kcal deficit. Fix protein at 1.8-2.2 g/kg, split the rest between fats (0.8-1 g/kg) and carbs to train hard, and adjust every 2-3 weeks based on results.
Order matters. Protein first, because it protects muscle. Fats second, because they support your hormones. Whatever's left you fill with carbs, the fuel to move weight in your sessions. A reasonable starting point:
| Macro | Recomposition target | Why |
|---|---|---|
| Protein | 1.8-2.2 g/kg | Protects lean mass and feeds growth |
| Fats | 0.8-1 g/kg | Hormonal support and satiety |
| Carbs | Remaining calories | Energy to train with intensity |
| Calories | Maintenance or -200/-300 kcal | Room to build without stalling |
Don't settle for generic numbers. Your weight, height, activity and goal change the split. Run our macro calculator to get a starting point adapted to you, then adjust with the real data from your scale and your mirror.
What to expect and how long it takes
Quick answer: In recomposition, expect slow but real change: the scale may barely move while your clothes fit differently and your strength climbs. A beginner or someone returning can see clear progress in 8-12 weeks; a lean advanced lifter needs months and moves millimeter by millimeter. Track with photos, strength and measurements, not just weight.
The most common mistake is waiting for the scale to do something magical. In recomposition, fat drops and muscle rises almost in parallel, so the scale hardly moves. That misleads people into thinking it doesn't work, when in reality their composition is changing. That's why you need other metrics:
- Strength in the gym: if you add weight or reps month over month, you're building muscle.
- Photos every 2-4 weeks: same light, same time, same angle. They tell you more than any number.
- Tape measurements: waist, arm, leg. The contour talks.
- How your clothes fit: the most honest day-to-day test there is.
Mistakes that stall recomposition
Quick answer: The mistakes that stall recomposition most are eating too little protein, cutting calories too hard, skipping progressive overload, sleeping poorly and quitting before 12 weeks. Also obsessing over the daily scale, which in recomposition paints a false picture of your real progress.
- Too aggressive a deficit: the shortcut that looks fast and ends up burning muscle. Recomposition lives at maintenance or a mild deficit.
- Low protein: no raw material, no building, no matter how hard you train.
- Training without progressing: repeating the same weight week after week gives no adaptation signal.
- Neglecting sleep: recovery is where the magic happens; without it, the rest underperforms.
- Impatience: quitting at week 5 when the change shows up from week 8.
How Makroa makes recomposition easy
Quick answer: Makroa makes recomposition easy by serving personalized meals with the gram amounts your body needs, high in protein and with macros dialed in, without you cooking or weighing anything. We operate only in Madrid, from €7.90/meal, with no subscription, refrigerated food (never frozen) and delivery twice a week.
The hard part of recomposition isn't understanding the theory: it's executing it every single day. Cooking high-protein meals with dialed-in macros, week after week, without getting bored or skipping it. That's where most people fail, not for lack of knowledge but because of logistics.
Makroa is meal delivery in Madrid built on personalized macro-based meal prep. You tell us your goals, we adapt the meals to the gram amounts your body needs, and you get them at home ready to eat. The culinary bar is high: food you actually want to eat, not the sad diet chicken and broccoli. Protein runs high in every meal, which is exactly what recomposition demands.
No subscription, so you try it without locking in. Refrigerated and never frozen, so it tastes and keeps like it was just made. And delivery twice a week so you eat fresh, not from a batch made six days ago. The rest (training hard, sleeping and staying consistent) is still your job, but precise nutrition stops being an excuse.
If you want to compare options before deciding, take a look at our guide to fitness meals in Madrid. And if you don't have your numbers yet, start with the macro calculator: without a clear target, no recomposition holds up.
Frequently asked questions
How much muscle can you gain in recomposition?
It depends on your level. A beginner can gain 0.5 to 1 kg of muscle a month in good conditions; a lean advanced lifter, a fraction of that. The more trained and lean you are, the slower it goes.
Do I need to eat in a deficit to recomp?
Not always. Many people recomp at maintenance. A slight deficit speeds up fat loss, but an aggressive deficit hurts muscle gain, so balance wins.
Recomposition or bulk and cut?
If you're a beginner or coming off a break, recomposition is ideal. If you've trained for years and you're lean, alternating bulking and cutting phases usually delivers more.
