This is all good if your goal is weight loss. However weight loss doesn't necessarily means higher fitness. Glycogen is fundamental if you do sports, and exercise is a major ingredient in getting fit. If I read correctly, exercise was not a big part of your experiment, how would you suggest modifying the experiment to accommodate one's exercising needs?
On a side note, I reached a similar conclusion on the role of "carbs at night", sleeping, and fats, and I read this interesting article https://aeon.co/essays/hunger-is-psychological-and-dieting-o... on the importance, for effective weight loss, of feeling satisfied (I believe there is also a reference to the relationship between eating fats and feeling satisfied).
