Why does the scale go up after a vacation or cheat meal?

On Ep. 105, Nikkiey puts it plainly: when you eat a lot of carbohydrates, your body holds on to water, so you feel puffier and the scale reads heavier. That is water weight and inflammation, not fat. She points out that it takes roughly 3,500 extra calories to gain a pound of fat, and nobody she knows does that without trying. On Ep. 37 she adds that the sugary foods and alcohol are a big part of why you can feel like you gained five or ten pounds. She has felt it herself after a birthday trip: inflamed, foggy, off. That feeling is real, but it isn't fat.

The good news is how quickly it passes. Nikkiey says that if you get back to your routine, you should feel much better within about four to five days. On Ep. 76 she describes clients she has coached for years who know a weekend away means bloat, and by Friday the water is gone and their photos look like the trip never happened. Some come home and see no change at all, because they stayed somewhat aware while away. On Ep. 162 she notes that after a cheat day her own scale sometimes went up, sometimes stayed the same, and sometimes even dropped.

There is a nuance worth hearing. On Ep. 76, Nikkiey warns that a full week of no movement and all-out eating is a different story. She says that pattern can mean seven pounds in a week, a week to get back into the groove and a few weeks to work it off. And on Ep. 162 she says one meal won't derail you; what does is a cheat meal that becomes a cheat day, then a cheat week, then a cheat month.

So the number after a trip or a big meal isn't a verdict on you. It's water. What matters, as Nikkiey says again and again, is getting right back to your routine when you get home.
