WOW! I didn't know so many people used a food scale. It has really opened my eyes to portion sizes. I can't say I will use it 100% of the time, but for now it's what my daughter and I need to make sure our sugars stay under control.
I LOVE my food scale. Can't live without it. When the battery died and it took me a day or two to find a new one I was lost, and I was so relieved when I found the battery for it and could use it again! I weigh everything that can be weighed on it when I'm preparing food at home.
I have one and I use it for everything. It stays on the kitchen counter and it is very well-used! DH has even started using it for some things and is shocked at serving sizes.
When I'm having to watch my nutrients more closely (like when I am losing vs. maintaining) I LOVE my scale. Very helpful and accurate (it weighs to tenths of a gram).
If I am maintaining and have more leeway/am focusing on satiety more than an exact number, I don't use it nearly as much. But it's still super helpful to have around.
