Stroke survivor - always hungry

My fiancé who is only 37 yrs old had a massive hemorrhage stroke on the right of of the brain in October 2015. She still has left side paralysis, but making some progress. One of her major issues is weight gain which is making her recovery more difficult. She is experiencing a feeling of always being hungry and has not had the feeling of being full since her stroke. She also does not remember what and when she eats. I continually remind her of what she ate, portions and the time she ate. I have tried recording everything she eats so she realizes how much she is consuming, but she doesn't have any interest and is only concerned about how hungry she is at the moment.

We have inquired with her neurological Doctor, family doctor and brain surgeon, but none of them have offered any solutions. Her family doctor suggested a wellness plan, but I know she will not follow it.

This hunger issue is also causing her frequent emotional breakdowns.

Any suggestions would be appreciated!
