Hi Chelle, welcome
Yes, from my experience, I'd say that's fairly true. But the weight losses and gains with the carbs are entirely fluid. For example, this week I ate a big carb meal on Tuesday and my weight shot up by 2kg
It has taken until this morning (Saturday) to come back down... and it's now less than it started with. All fluid
An annoying side-effect of the low-carb diet!!
