Body recomposition: who it suits, and which guide to read first

Recomp, cut or bulk

Every physique plan on this site starts from the same number, your TDEE, which is your estimated maintenance intake. What separates a cut, a bulk and a recomp is simply where you set calories relative to that number. The calculator's goal settings make this concrete: a standard cut sits 20 to 25 percent below TDEE, a mild cut 10 percent below, maintenance at zero, a lean bulk 10 percent above and a standard bulk 20 percent above. Those percentages are the site's defaults, not findings from a study, but they give you a single ruler to compare the three approaches on.

A cut buys speed on the fat side at the cost of muscle-building. Helms and colleagues' 2014 review of natural bodybuilding contest preparation suggests losing roughly 0.5 to 1 percent of body weight per week, with protein of 2.3 to 3.1 g per kg of lean body mass to help hold on to muscle while energy is short. A bulk buys speed on the muscle side at the cost of some fat. Iraki and colleagues' 2019 review of off-season bodybuilding nutrition suggests a surplus of about 10 to 20 percent and a gain of about 0.25 to 0.5 percent of body weight per week for novice and intermediate lifters, with protein of 1.6 to 2.2 g per kg.

A recomp parks calories at zero on that ruler, or a little below it, and asks protein and progressive training to do the steering. You give up the speed of both specialised phases in exchange for never being in a hard deficit or a visible surplus. That trade is excellent for some people and poor for others, which is why this hub opens with a self-test rather than a sales pitch.

The people it suits best are the ones whose bodies respond quickly to a new training stimulus: true beginners, lifters returning after time off, and people carrying enough body fat that fuelling some muscle growth from their own stores is realistic. The people it suits least are lean, experienced lifters, for whom a recomp tends to feel like months of maintenance with little to show. Between those poles sits a large middle group for whom recomp is a reasonable choice if patience is easier for them than strict dieting.

There is also research interest in the idea that the deficit and the training can coexist with muscle gain. A 2016 randomized trial by Longland and colleagues in the American Journal of Clinical Nutrition is titled "Higher protein during an energy deficit combined with intense exercise promotes lean mass gain and fat loss". The site has not yet read that paper's abstract, so this hub quotes only its title and draws no numbers from it. What it does tell you is the shape of the argument the recomp guides rest on: high protein plus hard training is what makes the muscle side possible when calories are not in surplus.

One person, three paths: a worked example

A hypothetical woman: 32 years old, 165 cm, 72 kg, estimated 32 percent body fat, training three to four times a week (the site's moderately active tier, 1.55). Mifflin-St Jeor BMR = 10 x 72 + 6.25 x 165 - 5 x 32 - 161 = 1,430 kcal. TDEE = 1,430.25 x 1.55 = 2,217 kcal. Lean body mass = 72 x 0.68 = 48.96 kg.

Calories use Mifflin-St Jeor with the site's multiplier and goal percentages, rounded to whole kcal. The rates and protein ranges are the cited sources' own figures applied to her numbers. Those sources studied different situations (Helms: natural bodybuilding contest preparation; Iraki: off-season bodybuilders; Morton: protein supplementation alongside resistance training), so treat each as a reference point, not a prescription.

Which recomp page answers which question

The five guides in this category were written to be read in a particular order. Skip any step you already understand, but resist jumping to the numbers before you know whether the approach fits you.

1. What is body recomposition? Read this first if the idea is new or if you doubt it works at all. It owns the definition, explains energy partitioning (how protein, training and calories steer where energy goes), rates different starting points from excellent to poor, and clears out the common myths. If the who-it-works-for table puts you in a poor-fit row, stop there and look at the cutting or bulking guides instead.
2. The recomp calculator. Open it once you have decided to try. It sets calories at or slightly below maintenance depending on your starting body fat, gives macro targets by starting point, walks a full example from TDEE to grams, and spends real time on progressive overload, because at maintenance the training is the signal that tells your body to build.
3. The recomp diet guide. Read it when the targets exist but your meals do not. It covers protein anchors and portion sizes, carbs around training, enough fat for normal hormone function, why under-eating sabotages a recomp, optional calorie cycling between training and rest days, and a sample day on a plate.
4. Recomp for women. Read it alongside the calculator if you are a woman, because the numbers are smaller and the scale is even more likely to sit still. It gives calorie and protein targets by bodyweight, explains cycle-related water swings that can hide progress, addresses the fear of getting bulky, and says plainly which hormone questions belong with a doctor.
5. How long does recomposition take? Keep it for the moment you start doubting the process. It sets expectations month by month and by training level, lists what speeds up or slows down progress, and explains how to measure change when body weight stays flat.

Where recomps usually go wrong

Most failed recomps do not fail because the idea is flawed. They fail because one of the three inputs quietly drifts, and with no big calorie signal in either direction there is nothing to mask the drift.

The first and most common problem is an unverified maintenance number. The calculator gives an estimate, not a measurement. If your real maintenance is a couple of hundred calories lower than the estimate, your recomp is secretly a slow bulk; if it is higher, it is secretly a cut. The fix is the same one every guide on this site repeats: eat at the estimate consistently for two weeks, watch the weekly average of your morning weight, and adjust before you judge the recomp itself.

The second problem is protein that is high on paper and low in practice. Morton and colleagues' 2018 meta-analysis found that the benefit of extra protein on muscle gain with resistance training plateaued at around 1.6 g per kg per day. Many people believe they eat that much and, once they weigh portions for a week, find they do not. On a recomp this is the input you cannot skip, because it is what lets muscle build while energy is not in surplus.

The third problem is training that is hard but not progressive. Turning up and sweating is not the same as adding load or repetitions over time. At maintenance calories, the training stimulus is the main reason your body would bother adding muscle, so a programme that stays the same for months gives it no reason to.

The fourth problem is judging the plan with the wrong instrument. A flat scale is the expected result of a recomp, not a sign of failure. Waist measurements, regular photos under the same lighting, and your training log are the tools that see composition rather than mass. People who measure only weight often quit around the point where the changes are starting to show.

The fifth problem is turning a recomp into a crash diet. Because fat loss feels like progress, it is tempting to slide calories well below maintenance. That removes the energy the muscle side was depending on and leaves you with a slow, mediocre cut. If faster fat loss is what you want, run a proper cut on purpose with the cutting guides; do not do it by accident inside a recomp.

Finally, a note of caution. A plan built around weighing food and tracking the body is not the right project for everyone. If you have a history of disordered eating, are pregnant or breastfeeding, are under 18, or have a medical condition that affects appetite or weight, talk to a doctor or registered dietitian before you start any of these approaches.
