Weight fluctuations

Absolutely normal. When we exercise, we create micro-tears in muscles, among other things - that's good, because it's part of the "build back better" cycle that happens with exercise + good nutrition. Repairing the body involves a little water retention. Some of us gain/drop that water, some hang onto it indefinitely when following a consistent progressively-challenging routine; for some, it does one thing with some types of exercise, but not all types. Regardless, it's normal.

This is a good read, very informative:

I was (?) fortunate, in that when I started losing weight, I already had a habit of exercise, and a habit of daily weighing (and noting the result) even when not trying to lose weight. That gave me a good understanding of how my individual body holds/drops water weight, which made fat loss less stressful. I wasn't disturbed by the random scale variations. Even now, in year 5+ of maintenance, my weight varies daily depending on a variety of factors, with the main mechanisms being water retention and higher/lower amounts of food in transit that will eventually become waste. I'm 5'5", and over the last week my AM weight has been as low as 125.4, as high as 129.8 . . . and those aren't start and end weights, they're just things that happened somewhere during the 7 days. It's completely normal.

What *wouldn't* be normal would be a continuous linear weight (either dropping, increasing or staying level). *That* would be weird. Sometimes people accomplish a continuous drop by consistently severely undereating, or a continuous increase by severely overeating . . . neither of which are good idea for health.

You're normal. 🙂
