I feel like I am just not eating enough

I am 5'2" 140 lbs. trying to lose this last 10-15 lbs. My macros give me a 1033 calorie limit, and 16 carbs. I just feel like I am never full, and I had a gastric bypass in 2001. My typical day is:

Breakfast:

* 5oz 5% Fage Greek yogurt * 1 T of Keto chow mixed in yogurt * coffee with 3 tablespoons HWC * 3 pumps of 0 cal 0 carb toasted marshmallow sweetener

Lunch

* 2 slices of American cheese * 1.5 oz of Deli Ham (Boar's Head) * 1 pc of choczero chocolate (I take sublingual medication everyday which tastes disgusting, and this masks the taste)

Dinner

* 5oz of keto pot roast or some other protein * 1/2c cauliflower rice

Snack

* Once every couple of days I will have a sugar free jello mixed with 1 t of HWC

I walk between 2.5 and 4 miles a day and have been doing 16:8 IF. I just do not feel satisfied with what I am eating. I also recently hid my scale as I was weighing myself every morning and just fluctuating between 138.9 and 140.5. Just looking for feedback.
