What happens if I increase calories too fast when reverse dieting?

On Ep. 360, Nikkiey calls this the yo-yo. You diet, lose the weight, then go back to eating whatever. Your calories jump, the body panics, and it stores the extra because the metabolism can't process that fuel efficiently yet. On Ep. 354 she separates a real metabolism repair from what she calls reactive overeating, which is eating everything in sight after restriction and hoping your metabolism resets. That surplus is too large and comes too fast for the body to use well, so the excess gets stored, and you miss the benefits of a structured reverse protocol.

She has lived the milder version too. In her video on a year of reverse dieting after 1,200 calories, Nikkiey shares that one week she increased calories way too fast and felt bloated and sluggish for days. She took it as a wake-up call: the process is slow, and slow is the whole point.

One distinction matters here. Nikkiey says the scale going up or staying the same during a careful reverse diet is not failure. You're eating more food, which weighs something, and you're refilling glycogen, which holds water. That's different from the fat gain a big, sudden surplus causes. Done gradually, she says she has seen many women work up to eating 2,200 or 2,300 calories, and their bodies respond when it's time for a deficit. If you've tried this on your own and stalled, she suggests working with a coach.
