Your period makes the scale jump - it's water, not fat
Your period can push the scale up by about half a kilo, and sometimes up to 2 kilos - but that jump is water, not fat. It peaks on the first day of bleeding and drops back within a few days.
Your period is on its way, and the scale suddenly jumps up. Your favourite kurta feels snug at the waist. You wonder if you gained fat overnight. Take a breath. Most of that jump is just water your body is holding for a few days. It comes, and then it goes right back down. Let's see why the number rises and falls so fast.
The scale went up during my period, so I must have gained fat.
mostly falseMostly false. To gain just half a kilo of real fat, you would need to eat about 3850 extra calories - that is like eating about 45 extra home rotis on top of your normal food. A jump that shows up in a few days and vanishes just as fast is water, not fat. Fat cannot pile on or melt off that quickly.
What that half-kilo on the scale could actually be
How big is the typical period jump?
Studies find the average jump is about half a kilo. But many women see 1 to 2 kilos. The peak hits around the first day of bleeding. Then it falls back over a few days. About 9 in 10 menstruating women notice some water retention. So if your scale jumps half a kilo to 2 kilos that week, you are in good company - and it is almost all water.
Assumptions: 0.5 kg x 7700 kcal/kg = ~3850 kcal - the extra calories you would have to eat to gain 0.5 kg as true fat. The scale jump is mostly water, so the fat actually gained is near zero.
How to ride out the jump
- Do not weigh yourself every day the week before your period. Weigh once a week, same time, same conditions. The daily number is mostly water noise.
- Drink more water, not less. It sounds odd, but staying hydrated helps your body let go of the water it is holding.
- Ease up on extra salt the week before - pickles, papad, namkeen, salty chips. Extra salt makes your body hold extra water.
- Keep moving. A short walk or easy yoga helps the water shift and eases cramps too.
- Expect the drop. The jump comes a few days before, peaks at the start, and is gone within a few days of bleeding.
The bottom line
When the scale jumps around your period, blame water, not fat. Real fat needs thousands of extra calories; this jump needs almost none. It peaks on day one and drops in a few days. So skip the daily weigh-in that week, go easy on salty pickles and namkeen, drink your water, and let the number settle on its own.
