It works exactly the same for me. I approximately know how much calories I should eat during the day and if I keep below it I slowly but steadily lose weight. It does not even matter what I eat, as long as I stay below the threshold I will lose weight.

At the moment though I am gaining weight. My life is stressful at the moment and one way of dealing with this is eating tons of food. Because of this I gained about 10 kg during the last year.
