>>936485153 (OP)even if you can't walk
it is literally just don't eat random bread/pasta/cookies/cake/soda
you can still eat fried shit, sandwiches, etc.
just cut down or cut some stuff off
if you can manage to do physical activity then even better
i went to physical therapy for a year to get into condition to walk 5k daily without pain, but it started as 100m and slowly ramped up
just don't think it will take only 2 weeks to solve everything
