This planning estimate projects how long reaching your goal weight could take, using the rough rule that a pound of body weight is about 3,500 calories. It does not track fat and muscle separately, so treat the timeline as a rough target.
Recomposition is the one goal where the scale can sit almost still for months while your body changes underneath it, which is exactly why people quit it early. Here is what a recomp actually is, who it genuinely works for, and how to tell it is working.
What a recomp actually is
Recomposition means losing fat and building muscle at the same time, instead of running a fat loss phase and a muscle building phase back to back. Those two jobs pull in opposite directions. Losing fat needs less energy coming in than you burn, and building muscle generally wants a little more. Your body can cover part of that gap by pulling from stored fat and putting it toward new tissue, but only under specific conditions, and only up to a point. That is the whole trick, and also the whole limit.
Who it actually works for
I will be straight with you, this is not equally available to everyone. Recomp works best if you are new to lifting, if you are coming back after a long layoff and once carried more muscle than you do now, or if you are carrying enough body fat that there is plenty of stored energy to draw on. In those cases muscle arrives fast enough to show up alongside the fat loss. For a lean, experienced lifter it gets very slow. Not impossible, just slow enough that most people in that spot are happier picking one goal at a time.
What has to be true
- Enough protein to build with, around a gram per pound of body weight
- Real resistance training, most weeks, with the weight or the reps creeping up over time
- Maintenance calories or a small deficit, never an aggressive cut
- Sleep, because that is when most of the repair happens
Miss the protein or the training and a deficit just takes weight off, some of it muscle. Pushing calories down hard makes that worse, not faster.
A worked example
Say you weigh 200 pounds, you want to reach 180, and you leave the rate at 1 pound a week. The planner returns 20 pounds of total change across about 20 weeks, which works out to roughly a 500 calorie daily deficit. Notice what it is being honest about: it plans the weight change, not the composition change. Whether those 20 pounds leave as mostly fat depends entirely on the protein, the training, and how patient the rate is.
Why the scale is the worst judge
In a real recomp, fat leaving and muscle arriving partly cancel each other out on the scale, so you can look genuinely different and weigh the same. Watch your waist measurement, how your clothes fit, whether the weight on your working sets is moving, and a body fat estimate taken the same way every few weeks. Then give it room. Recomp is measured in months, not weeks, and a few months in is usually when the first clear change shows up. If you want the composition side laid out month by month, the Recomp Timeline projects it, and whether you can lose fat and build muscle at the same time covers who it actually works for.

Aim to lose 0.5-1% of body weight per week; slower rates preserve more muscle. Revisit monthly and adjust to actual progress.
