I need HELP. belly fat will not go away.

I’ve got this little pouch in my lower belly and hips and I cannot get it to go away. I’ve lost weight but this just is being stubborn af. I’ve drastically changed my diet (switched from reg soda I was drinking 1-2 times a day to diet, and cut out candy for the most part that I was eating 1-2 times a day). Any tips guys? I go to the gym often (2-3 times a week). I do ab, legs, arm strengthening and hiit for my cardio. I’ve hit a plateau and idk what to do!!! It’s in flattering because it sticks out over my swim suit bottoms (and no my bottoms aren’t too small) HELP ME 🤪. Edit: I’ve also been on lo loesterin for 6ish months now so I feel like that wouldn’t affect my inability to lose weight
