Heyy hun :)
Since pasta and bread can be really high on calories ( depends on how cooked and what its made of) it can be hard to burn it off. Maybe if you tell your parents that you want to eat differently they will let you ? You can tell them you want to be more healthy cause healthy lifestyle will make you feel a lot better , so maybe your parents wont judge and will support you.
But … maybe if you still eat pasta (yummm) and all of these other stuff, then you can take a walk or go for a run/jog after.
About the thigh gap thing. You should just train your inner thighs. Don’t search for “thigh gap workout/exercise” , go for “inner thigh workout” . I’ve said before but hands down my favorite is xHit youtube channel.They have amazing workouts. DIfferent body areas, celebrity inspired workouts, yoga ,pilates and a lot more ! (ps: i promise they don’t pay me to say these words :DD )
I don’t know did you get any help of this, but it’s kinda hard to help for me cause I don’t know how you parents are. Probably you just have to try different things and see what works best for your body :) If you need anything else let me know.
Lots of Love :) xx
