Hi, Msamy!
Can you provide a sample of a day's menu? That way we could look for ways that might make your daily diet more filling.
Generally, protein is filling. On the days that I have a large amount at breakfast (30+ g), I practically have to force myself to eat during the rest of the day because it kills my appetite. I don't always have such a high protein breakfast though because I like variety, but when I do, it really does work like a charm. You don't need to go that high protein. It's a good idea though to have at least some protein every time you eat.
Fiber and healthy fats are also great for mitigating hunger.
Reducing or entirely eliminating certain foods can help a lot too. Sugar or empty carbs make me hungrier than I would've been if I hadn't even eaten them. I limit them. When I do have them, I pair them with protein and fat. That helps a lot with my hunger levels.
1300 is low, so it does take careful selections to be satisfied.
Even then, you may find that it's still too low for you and opt to go slightly higher in calories, and there's nothing wrong with that.
