My opinion, from my own experience: Sure, that definitely works. But the choice of cutting fat is kind of arbitrary. You can do the same with sugar & carbs and get basically the same result w.r.t weight loss. I think this illuminates the real underlying issue with modern diets which is not that we eat "too much of X", but rather "too much of everything, too frequently". Approaches like this work not because "fat is bad" or "carbs are bad", but because they provide a simple, concrete framework for diet choices that ends up reducing overall calorie consumption.

It's just way easier to rack up calories if the thing you're eating is higher in fats. Remember that fats have no fiber (neither does protein, but that's another conversation), so you won't 'feel' as full, which can easily lead to a much higher calorie ingestion rate that you're body won't be able to keep up with.

Another big thing is portion control! You hit on the nose with eating too much of everything. Something else I've done is making myself smaller plates, but also taking much smaller bites and taking a much longer time to finish the plate. I make it take as long as possible. That way by the end of the plate I have a more accurate sense of how hungry I still am or not.

It's tough to summarize all of points of my current regimen since I've pulled bits and pieces from lots of different sources and put some personal experience into the mix.

Heh... What's interesting is I personally feel the opposite. I can eat thousands of calories of carbs/sugar no problem, but I fill up on fat pretty quick. I did the keto diet for about 4 months and almost never went over my daily calorie budget, basically without even trying that hard. Most days I had to remind myself to eat more because I was way under.

I wonder if this is a case for emphasizing that "one size fits all" doesn't work in dieting, either. It seems likely that satiety for various food sources might vary based on biology and lifestyle too.
