I've lost over 140 pounds by not counting calories.
However, I do remain calorie aware, as I don't want to accidentally eat 1000+ calories in one meal.
I read labels. I look up nutrition information for restaurants. I do my best to stay informed so I can make good choices. And in the past year, I've been keeping a food journal to stay mindful about my eating. I choose a lot of whole foods with healthy fats, but very few simple carbs. I avoid added sugar and overly-processed junk as much as possible. I eat a lot of fresh veggies every day. And I don't worry about actually counting calories. I've got anxiety issues and have found that tracking calories makes me obsessive and absolutely miserable.
