Reaching your goal is only half the job. The weeks right after a diet are where a lot of people undo their work — not because the diet failed, but because the transition back to normal eating was never planned.
After a sustained deficit your maintenance is lower than when you started — partly because you weigh less, partly from a modest metabolic adaptation. Jump straight back to your old intake and you can swing into a surplus overnight, which is how hard-won loss comes back. The fix is to raise calories gradually.
Reverse dieting is the deliberate, step-by-step increase of calories after a cut — commonly adding around 100–200 calories per day at a time, holding for a week or so, and watching your weight before adding more. You keep raising intake until your weight stabilises at your new, higher maintenance.
A small bump in scale weight as you add calories is normal and is mostly food volume, water, and glycogen — not fat. That's why you judge by the trend over weeks, not the day-to-day. Reverse dieting won't "supercharge" your metabolism beyond restoring what dieting suppressed, but it does make the return to maintenance controlled instead of chaotic.
Commonly 100–200 calories per day at a time, holding a week or two between steps and watching your weight trend before adding more.
A small rise is normal and is mostly water, glycogen, and food volume rather than fat. Judge by the multi-week trend, not single days.
Keep raising calories until your weight holds steady — that intake is your restored maintenance. The tracker can read it from your trend directly.
