Has anyone tried it

For me, personally, I find it augments but does not replace logging. Depending on where you're getting your info, some brands of this method are outright rigid. It's okay to be hungry sometimes, and it's okay to eat for reasons other than hunger. It's okay to plan your meals, be overfull sometimes, eat for social connection...etc etc. I find pausing to ask myself if I'm full every minute takes away from the food experience. Knowing how many calories my meal has allows me to not worry about it while eating and fully focus on my food satisfaction.

Some proponents insist that if the body doesn't lose weight on intuitive eating then you shouldn't be aiming for weight loss. In fact, this approach was developed to heal a turbulent relationship with food, not for weight loss or as yet another diet. They were very clear that weight loss is just a side effect that may happen for some people, but you shouldn't be focusing on it or even pay attention to it. While I agree people need to eat in a sustainable way and maintain a weight that is realistic for them to maintain (even if it happens to be overweight), outright giving up without even attempting to acquire weight management tools sounds silly. There is a lot to learn about eating through logging or at least conscious intake watching: what foods are more worth it than others, what foods are more filling for the calories, how often you can enjoy a higher calorie item without sabotaging weight management....etc. Falling back on "mah genetics don't want me to lose weight" is defeatism. I'm all for not being overly anxious about food and I strongly advocate it, but I feel the way they're approaching it is a little bit extreme and can create its own anxieties and guilt cycles.

They're also against any kind of calorie monitoring or making diet-informed choices. Choosing something over another for the calories is sometimes worth it when the eating experience doesn't really feel different (diet vs normal soda for me, for example) or when you forgo one choice to have another choice you enjoy even more (like having a light breakfast in order to have a heavier lunch I really enjoy).

With that said, I do use the hunger scale to make food decisions often because being hungry too often isn't pleasant, and being overfull too often robs me of the calories I could be spending when I do need them. It's just common sense. I try to strike the right balance for me in terms of hunger, enjoyment, socialization, sustainability, and nutrition.

You don't have to log your food if you're one of the lucky people who can manage their weight without logging, but you can do that on your own terms based on your own experiences and from an informed place instead of trying to squeeze into yet another generic predefined box of rigid rules. Reading the book to see if there is something you'll find useful isn't a bad thing, just don't treat it as gospel.

It was my plan nearly every time before this time. It never worked out for me.
