The short answer
Reverse dieting is the intentional, gradual increase of calories over time, usually after a fat loss phase or years of under-eating. Nikkiey explains that the goal isn't weight gain. It's bringing your metabolism back up, improving energy, mood and sleep, and keeping your results so your next fat loss phase starts from more food.

The full answer
On Ep. 197, Nikkiey explains why this matters. When you diet for a long time, your body adapts to the lower intake, which is called metabolic adaptation. It gets used to running on fewer calories. On Ep. 284 she calls reverse dieting "not a trend. It's literally a fix" for women whose metabolism has been worn down by years of back-to-back diets. On Ep. 354 she adds that it also helps you rebuild muscle and work back toward your true maintenance level. That way, when you diet again, you have a higher calorie ceiling and more room to create a deficit without bottoming out.
How it works, according to the show:
- Find your starting point by tracking honestly without changing anything: seven days (Ep. 197) or one to two weeks (Ep. 354).
- Add calories slowly. On your own, Nikkiey suggests about 50 to 100 a week (Ep. 197). Her broad guideline on Ep. 354 is about 100, maybe 150. With a coach she may push it to 150 or 200, depending on the person and their mindset.
- Keep protein where it is or raise it. It doesn't go down during a reverse.
The pace is slow on purpose. Nikkiey says gradual increases give your metabolism time to rise at roughly the same rate the calories come in, which keeps fat gain to a minimum. The same approach applies if you've been under-eating for years. Going from 1,100 to 1,800 calories should be a gradual climb, not a jump.
Not sure if you need one? On Ep. 284, Nikkiey lists the signs. You eat under about 1,500 calories and aren't losing weight. You've dieted several times in the past year. You feel tired, cold or anxious, sleep poorly, have stopped seeing gym results, or binge when you restrict. If even two of those fit, she says you're not ready for another cut. Your body hasn't failed. The repeated dieting is what needs fixing.

Metabolism, Eating More & Reverse Dieting
How long does it take to repair your metabolism?
It depends on how adapted your metabolism is. Nikkiey's ranges: about six to 12 weeks for mild adaptation after a few months of moderate dieting, closer to three months after a year or more of restriction, and six months to a year after many years of chronic dieting. Your body's response sets the timeline, not a calendar.

Metabolism, Eating More & Reverse Dieting
Will I gain weight when I start eating more?
Probably a little, and that's expected. Nikkiey explains that when you start eating more during a retrain or reverse diet, your weight will usually fluctuate about two to five pounds from water, glycogen, food volume and salt, not fat. If the gain keeps climbing or holds around five pounds, the increase was likely too fast.

Metabolism, Eating More & Reverse Dieting
Is my metabolism broken from years of dieting?
No. Nikkiey's view is that your metabolism isn't broken, it's down-regulated. After years of eating too little, your body adapts to survive on less: it burns fewer calories at rest, moves less, raises hunger and holds on to fat. What adapted can readapt once you change the environment it's responding to.
