Temporary weight gain explained

Thank you for sharing. This weekend I ride my bike 13 miles and I hiked a mountain; I knew I was at a big calorie deficit, but the scale this morning skewed a gain. I knew it must be temporary, but actually understanding the science of it really helps keep any sense of being discouraged in check! Thank you.

I am relieved to see this. Working at a deficit, started using heavier weights a couple of weeks ago and this week there was a 1/2 lbs gain on the scales...was disappointed but now really relieved to find that there is an explanation. Thank you.
