Interesting. But to anyone debating whether or not counting calories could help them: try it.
As soon as you start having to add calories for every bite you take, laziness takes over and it's not worth figuring out how many calories are in a handful of nut mix sitting out on the counter. It's easier to just not grab a handful. Then you end up eating and snacking less and end up losing weight.
Once you add in a food tracker that tracks things like protein and vitamins, it gets even better. You start noticing that you need to eat less salt; more protein etc and you start choosing better foods.
At the end of the day, if you have the discipline to track, eating better will come easy, which will make the initial 10-20 lbs super easy to lose.
