I weigh myself every 3 months at my follow-up with my surgeon. But, that is due to my therapist and nutritionist highly recommending it for me. I have a long history of becoming way too obsessed with the scale, which would lead me to restrict, then binge/restrict, then binge/purge, then finally binge-eating all together. It's just been my downhill spiral for forever. Now I have finally been learning to pay attention to my health and how I feel with energy, health, and just overall mental health. It's been a relief to not weight myself so much. However, that is not a rule for all. For me it was highly recommended by my team. But, for others they need to weigh more often.
