If your scales are reading higher in this heatwave, don't panic, It's not fat gain.
In hot weather your body naturally holds onto more fluid to help regulate temperature and maintain hydration.
Add in more sweating, changes in electrolyte balance, more carbohydrates, a few drinks, more activity, exercise related inflammation ...and the scale can jump surprisingly quickly.
To gain 1kg of body fat overnight would require thousands of calories above your normal intake.
So if the scale is up after a hot day, a BBQ, a meal out or a busy weekend, don't assume you've undone all your hard work.
Look at the trend, not the day.
Hydrate, keep doing the basics well, and give your body a few days to settle.
The scale measures weight, It doesn't measure progress.
