Maintenance is a range, not a single number. Your weight will move within a few pounds week to week from water, food volume and hormones, and none of that is fat gain.
It is also the phase most people skip, which is why weight regained after a diet is so common. Learning to hold a weight is a skill, and it is worth deliberate practice.
Any calculator gives an estimate; your own data gives the answer. Eat a consistent intake for two weeks, track weight daily, and compare weekly averages.
If the average held steady, that intake is your maintenance. If it drifted, adjust by roughly 100–150 calories per day and repeat.
Maintenance is not fixed. It shifts with activity, training load, stress and season, so expect to re-check it a few times a year.
Pick an acceptable band of around 2–3 kg rather than a single number. Inside the band, do nothing.
Acting on every daily fluctuation leads to constant unnecessary dieting and makes food far more stressful than it needs to be.
If the weekly average leaves the top of your band for two consecutive weeks, tighten intake slightly. That is a signal; a single heavy morning is not.
Maintenance is the easiest time to lose the training habit, because there is no visible goal pulling you forward.
Keep lifting two to four times a week. Muscle is far easier to keep than to rebuild, and holding strength preserves the results of any previous phase.
Set a performance goal to replace the body-composition one — a specific lift, a running time, a skill. It keeps consistency without needing the scale to move.
Maintenance is not a reason to let protein slide. Around 1.6 g per kg supports muscle retention and keeps you full.
Adequate protein also makes the occasional larger meal much less consequential, because the rest of the week stays structured.
Keep the habits that got you here. Most regain comes from dropping the routines that worked, not from any single meal.
Travel, holidays and busy periods will interrupt the routine. Expect it rather than treating each one as a crisis.
A week of higher intake adds far less fat than the scale suggests — much of the jump is food volume, salt and glycogen, and it resolves within days.
Decide in advance what your return looks like: the first normal meal, the first session back. Recovery speed matters more than avoiding the disruption.
Eat a consistent amount for two weeks and compare weekly average weights. If the average is stable, that intake is your maintenance.
Daily swings of 1–2 kg are normal and driven by water, salt, carbohydrate and digestion. Judge by weekly averages instead.
Not permanently. Many people track for a few weeks to learn portion sizes, then keep the habits and check in only if their weekly average drifts.
