I think the OP is getting an unnecessary pasting, and she's been very gracious in the face of some very unpleasant responses (like the one saying she was babbling).
Reducing calories does make you lose weight. However, calorie counting is difficult to sustain forever, as many people have said already. Calorie counting involves weighing/measuring food, recording and restricting portions or ingredients. It's not really something you can do by eye - which is why the NHS talks about how your plate should look, and uses easy comparisons like a piece of meat no bigger than a pack of playing cards or whatever. It's very difficult to do it when you eat out, or at a friend's house where you can't see what went into the food.
There are also a number of people saying that they calorie count when they notice themselves putting on weight, lose a bit, then stop counting until the next time. That in itself is proof that calorie counting isn't sustainable - every person who has said that is coming on and off calorie counting, and their daily diet in between times is causing weight gain. In some people this will be extreme yo-yoing, and in others it will only be a few pounds up or down. The OP is trying to make the point that this is not effortless weight maintenance - hence why she said that calorie counting doesn't work.
The holy grail is a daily diet that doesn't cause weight gain. We all know effortlessly thin people who have the balance right, and the ones that I know aren't counting anything or cutting food groups. However, they also don't eat a lot of processed shite and tend to choose nutritious food because they like it and they know it's good for you.
I'm currently losing weight (8lbs in 8 weeks) by drastically reducing sugar and processed foods. I've also reduced wheat, but I'm still eating some - it's just that a lot of wheat products also have sugar, like biscuits/cake etc, and others are very processed, like supermarket bread. I'm not fasting, and I'm eating carbs in the form of rice, potatoes, oats, vegetables, fruit etc, so I'm not in ketosis. I'm eating full-fat dairy, fish, eggs, meat etc. I don't count anything, and I don't fast or not snack if I'm hungry or anything - although I'm naturally not that hungry because I'm not having sugar highs and lows.
I don't yet know how sustainable this will be, but it feels easy - I'm just thinking about whether something's sugary/very processed or not, not wondering how many grams of cheese are on a baked potato.
