Can you diet and BF?

Im not talking anything crazy. I’m just feeling pretty blue about my PP body and wanting to be a little more mindful about what I eat. My body type typically responds best to low carb (not zero, again nothing crazy). I worked so hard to get my supply up I just don’t want to chance issues with it, but my mental health is struggling a bit ☹️ anyone else diet and BF? Mindful eating is great but I know myself and I gotta kinda be strict if I’m gonna push past the cravings
