Anyone else notice this? I noticed it a couple years ago with the first foray with a big weight loss over the summer, and I'm seeing it now. It's normal and not "fat" gain, but the body just acclimatizing to heat.
Here's my "noticing" the water weight gain. Yes, it's that TTOM for me, but I usually see a jump on the scale for 1-2 days tops. I'm still holding the fluids 4 days later and it happens to coincide with heat. We don't over air condition the house, so it is warm in the home. Plus, I go out in and out all day and take walks in the summer - I am NOT avoiding heat very much. I think until we have a cool down for several days/week, the water weight gain is to stay while the body tries to regulate it's temperature. What that will mean is that for this month, probably, I will see less of a weight loss on the scale as my body adds water to combat heat. In the fall, there will be a month where I will see a larger loss than I would expect and that will be from the body dumping the extra water as it tries to warm up in the cooler months. All totally normal processes that we tend not to think about.
So... don't sweat a gain gals (and fellas) if you have been eating OP and everything else is normal - it's just water weight in the summer and it's normal. Read about it here:
