This projects a fat-loss recomp where you train hard, eat near maintenance with enough protein, and hold lean mass flat. Fat loss is modeled at a steady monthly pace and slows in reality, so treat the finish date as a soft planning estimate rather than a promise.
A projection is a plan, not a prophecy. This one assumes you hold every pound of muscle you have while fat comes off at a steady pace, which is the optimistic version of a real recomp. Here is how to read the timeline it hands you, and what usually moves it.
The honest rates
Fat loss is best planned as a percentage of your body weight, not a flat number of pounds, because a 250 pound person and a 150 pound person are not working with the same margin. The two pace bands here, about a quarter and about a half percent of body weight in fat per week, are deliberately conservative. Eating genuinely at maintenance rather than in a small deficit runs slower still, closer to half a percent to one percent of body weight a month. Muscle is the slower half by far. A beginner can add a meaningful amount over a first year of consistent training, but past that phase most people are looking at a few pounds a year, not a few pounds a month.
A worked example
Take 200 pounds at 28 percent body fat, aiming for 20 percent, on the steady pace. That is 56 pounds of fat sitting on 144 pounds of lean mass. Holding all 144 of those lean pounds means fat has to come down to about 36, so 20 pounds of fat is the real job. The projection lands around five months: roughly 196 pounds and 26 percent after month one, about 187 and 23 percent by month three, then 180 and 20 percent at the finish. The patient pace takes about ten months for the same change. Same destination, half the speed, better odds on the muscle.
Why projections drift
The math holds lean mass perfectly flat and removes fat at a constant rate. Neither is quite true. Adherence is the biggest lever, and a few scattered weeks off over a season stretch the whole line. Sleep and stress quietly change how much you eat and how well you recover. Training quality moves this more than training volume does. And the pace eases off as you get leaner, because a smaller body burns a little less. Expect the real timeline to run long more often than short.
What progress really looks like
Not a smooth line. Mostly flat stretches where nothing appears to be happening, broken up by a week where something suddenly looks different. Water and food volume can hide several pounds of real change for a while. That is why I judge a recomp on the trend across four to six weeks, using the same body fat estimate method every time, alongside whether the weights on your main lifts are moving.
When the timeline slips
First check that it actually slipped. Four flat weeks measured the same way is a signal, four flat days is noise. If it is real, work down this order: protein first, then training consistency, then sleep, then calories. Most stalled recomps turn out to be an adherence problem wearing a metabolism costume. When you do adjust calories, adjust gently and give it three or four weeks before judging, and use the Recomp Calorie Planner to see what a change of that size does to the finish date. For a worked example of the whole arc, see how long body recomposition takes. Cutting hard to make up lost time is the reliable way to lose the muscle this projection assumed you would keep.
