They were taken the same day.
The first photo was taken right before breakfast.
The second right after lunch and then the third was right after dinner.
People automatically assume that I walk around with abs all the time and that is NOT the case lol! Throughout the day, you will bloat-it's totally normal. No, it doesn't mean you're fat. It's called food and water. Often times, we get so hung up on the fickle stuff that doesn't even matter.
Why worry? Everyone bloats. So... Don't sweat it!
