Always hungry !

You are not alone! I am often hungry. Part of it is probably just getting used to the calorie deficit. In my case, before MyFitnessPal when I wasn’t tracking and just eating whatever I wanted and how much I wanted, I wouldn’t be surprised if I was consuming 2,000-3,000 calories a day. I went directly from that to a 1,590 calorie budget. It takes time to adjust I suppose. They say it takes 21 days actually, for something to become a habit. I’ve been on here for 20 days! Lol.
A little snack within a couple hours before bed helps. Because if you go to bed hungry, you wake up in the morning starving! Or at least I do!

You may need to add more good fats to your diet as good fats a satiating.

You could try changing what you are eating. Non-starchy vegetables are very low in calories so you can eat a lot of them. Fat is high in calories, but very satiating. I find I feel fullest when I eat both more volume of vegetables and a higher percentage of fat.

If you're hungry, you can eat about a pound of lettuce for around 70 calories. That'll fill you up, but probably isn't very appealing, but you can add about a pound of low calorie non-starchy vegetables to some chicken breast and saute the whole thing in a little fat which will be about twice the calories of just eating the chicken breast alone, but will keep you full about four times as long.
