I failed to keep it up but it worked for a few months. A simple food portion control measure: identify a geniunely small bowl, the calorie dense portion of all main meals must not exceed it's volume. For snacks come up with a similar shorthand, a tablespoon portion, or a small handful. If you eat mostly complex carbs, fats and protein while following rules around portion sizes you should get a good calorie deficit while mostly avoiding excessive hungriness, and saving effort you might spend weighing and journaling foods which you need to resist over eating and redirecting attention. Its almost "just eat less" but with a bit more how-to.
