In regards to your diet, I would count the calories tightly. There are a lot of empty calories in what you described, specifically carbs. Go online and determine what your BMR is and then compare to calorie intake. Make changes as necessary to obtain a calorie deficit.
You’d surprised at what adds up and how easy it may be to remove a few small items to get to negative.
Count every dollop of sauce, every vitamin ( yes, vitamins add calories), powders, etc.
Are you exercising? That helps your metabolism as well.
Finally, losing slow is still losing and succeeding but really try to eat clean and lose some of those empty calories.
