I was measuring things, haven't so much in the last 1-2 months. A few things I still do, more because they're hard to eyeball than because they're calorie dense.
For example, I usually use 1/4 of an avocado, and don't try to weigh or measure it. I even eyeball my granola, but it goes into a tiny little container that makes eyeballing it easy. OTOH, I measure the yogurt and blueberries in my morning snack - with the container I use to take it to work, eyeballing is just awkward - the ratio of the size of the container to the amount of each item is too high. I also measure the 1/4c of pom juice that I mix with my berry seltzer for my dinner drink. Again, it's because it's just hard to tell in the glass I usually use. But for the same drink, I eyeball the splash of white wine I use
. It's only a tbsp or so, and it goes in first, making it easy to see how much.
I don't find that I start eyeballing bigger and bigger. Certainly my success with this was built on measuring for a long time and learning from that.
