Digital food scales and low carbing

I think for most people, LC doesn't require a scale to weigh food and
it only complicates things, makes it more difficult, and more likely
for people to decide it's too much trouble. It's pretty easy to get a
feel for how many carbs are in a typical serving size of various
foods. And if you intend to be successful long term, that's
important, unless you want to carry a scale with you. There's no
magic in hitting the exact numbers either. Even in induction, if you
happen to hit say 30 carbs instead of 20, Atkins will still work.

My problem is that I have no idea what portion sizes are actually like. I had
been on a ultra long stall (so long that I lost track of time) which is what
motivated me to buy a scale in the first place. I had no idea how 100g chicken
meat look like until I weighted some for the 1st time.
