I have definitely noticed this pattern in my own weight!

Also could depend on where you are in your cycle.

If you were dieting and losing fat, but the scale may not have shown it due to water retention from your cycle. Then the water retention goes away, and whoosh.

Yes, I'm trying to lose 10 lbs and was very pleased when I stepped on the scale, but we'll see if tomorrow i see the same thing.

This is what I learned about luteal phases from the fitness person I follow (he's not an instagram model, he's a leading researcher in the field):

The mesntrual cycle is roughly 28 days (never) long. It has 4 phases:

Early follicular: first 7 days after menstruation
Late follicular: next 7 to ovulation
Early luteal: first 7 days after ovulation
Late luteal: PMS week

Here is the impact of those phases on a woman's bodyweight via water retention.

Early follicular: lowest
Late follicular: estrogen causes water retention due to a change in sodium handling
Early luteal: low
Late luteal: drop in progesterone (which blocks the mineral corticoid receptor) causes a rebound water weight gain also due to a change in sodium handling.

Homework assignment: consider what happens if you compare any week to any other week. Or what happens if you start a diet in the early follicular and the compare it to the second week or fourth week of the cycle. Or even the third week.

Here's a faster recommendation: do not EVER compare bodyweight (and other body comp methods can also be thrown off) on an every other week schedule type of schedule as you will always hit one of the weeks that is off from the previous.

Compare week 1 to week 1 (after the first day of menstruation)
week 2 to 2
3 to 3
4 to 4

My range is 3 up or down (so perhaps 5 total range); and my husbands is more like 7.

We have hardwood floors in the bathroom (previous owner's choice) plus some sloping. Where I put the digital scale on the floor can make me lose or gain weight.

Did you weigh yourself at the same time of day? If yesterday you had a lot of water and weighed yourself late in the day, that could be the difference between then and this morning.

When you weigh yourself you need to give it a 5 pounds margin of error because of various factors such as BM, water retention, water weight, etc. Therefore, it's possible. It's also almost physically impossible to burn 4 pounds worth of calories in a day.

I kind of think it's my scale too.

Definitely wasn't dehydrated either day. I drink a lot of water daily.

Yes, I finally had a BM after 3 days but damn. 4 lbs!!!???

BM

I'm known to drop a pound in a day, but never 4. Yesterday I weighed myself and was 136. This morning, I stepped on the scale and was 132. How is that even possible?
