am i affirming from lack?

so, i’ve seen someone have a success story by robotically affirming “no matter what i eat, i am constantly losing weight until i reach XY kg.” and i too have been affirming it, yet, when i think about it—the sentence itself operates from lack. meanwhile i wanna be XY kg without dieting or exercising. furtermore, i gave in today and measured my weight because of fear i am instead gaining more weight. will any of this affect my results?
