Yes, I am aware, my point stands. I highly suspect any diet that restricts most food groups will produce similar effects no matter what the food groups are. It's far from "remarkable," its what happens when you micromanage your diet plus a small dose of the placebo effect. People have written exactly the same thing about a high carb vegan diet, for example.

My mother in law also has a "I just don't eat [several random food groups]" non-calorie restricted diet as well, but the food groups are different, she says the same types of things and lost over 100 pounds and has kept it off for like seven years. Same with other people I know with omitting other random food groups.

(My mother in law actually eats outside her chosen food groups regularly, she just is really, really, really misinformed about what's in food - which further illustrates my point that it's the micromanaging and restriction, not the type of food consumed.)
