In general, lower belly fat is the most stubborn of all -- it's usually both the last to go and the hardest to lose during diet/exercise. Like others have said, it's going to take time and consistency, paying close attention to a caloric deficit. With that said, calorie deficits get trickier the more fat you lose and there are two things to keep in mind:

1. The more weight you lose, the less calories your body needs to function. Because of this, the gap between your maintenance calories and your caloric deficit will start to shrink. As such, you will still lose weight maintaining the same deficit but the loss will be much slower.

As you get further and further into it you might need to recalculate your maintenance calories for your new, lower weight. At that time, you might need to lower your caloric deficit number even further, but it gets harder to do once you start creeping closer to an unhealthy deficit that deprives the body of what it needs to keep organs functioning and healthy so don't feel like going lower will always be the answer. Sometimes you just have to deal with the slower loss per week, other times you might find yourself dealing with the second thing to keep in mind.

2. As you lose more and more weight, your body will start to get more and more efficient at running off of your caloric deficit. While it's common for a lot of us to stall for a bit at a certain point and then slowly crawl toward our body fat goals, sometimes it finally hits a level where it needs a jump start.

Some confuse this with "starvation mode" where your body thinks it's not getting enough calories and will desperately hang onto body fat to extend survival during a deficit instead of losing it. However, this is extremely unlikely as someone would essentially have to actually be dangerously starving to activate this survival mechanism.

What actually can happen instead is that your body just gets really efficient at running off of a deficit and therefore doesn't feel it needs to tap into the fat to perform as you are. If this does happen, you can try a calorie zigzag (also known as calorie cycling). This only works if you are strength training (resistance training with weights or bands, etc.) two or three days a week. On the two or three days you do resistance strength training, eat just a little bit more than your maintenance calories. Then, on your rest days, cardio days, yoga days, whatever days you're not strength training, you go back to your caloric deficit.

This essentially tells your body on strength training days to use that slight caloric surplus to rebuild those muscles you just broke down during your workout, signaling you need these extra calories for a muscle bulk cycle. Then, on the other days, when you go back to your original caloric deficit, it "tricks" your body into tapping back into the stored fat for the extra calories that it was just told it needs to rebuild your muscles. So while it seems odd, sometimes you need to take two to three days a week on a slight surplus (I strength train three days a week so I do a slight surplus on my two toughest days and then maintenance calories for the other day) and then drop back down to a caloric deficit below your maintenance calories for the other four to five days in the week.

I wouldn't think you'd need to do this just yet, but it's something to keep in mind. It sounds like you are just approaching point #1 where the fat loss slowdown begins and just takes more time. Be patient here but also be mindful and carefully evaluate when you need to change things up so you don't spin your wheels without going anywhere at that point.

Note: Also make sure you are getting enough protein and essential amino acids to maintain/build your muscles during your caloric deficit. As muscle building tends to require a caloric surplus, having the right amount of protein and doing strength training will tell your body that it needs to still maintain/build your muscles during a caloric deficit. This way you make sure your weight loss is consistently fat loss and not muscle loss. If you don't do this, your body might break down muscle even further to use the amino acids it gets from doing so in order to send them to the vital organs to function and survive. And of course, it would be using broken down muscle weight instead of solely tapping into the fat you want to lose, thereby making fat loss that much slower!
