Something is wrong here. Either with your estimates or otherwise. On average the human male burns around 2000 calories for existing and living a semi-sedentary lifestyle add to that ~500 calories of burn. You’re eating 1600 calories, meaning you burn 1000 calories a day in fat that isn’t offset by food. 1lb of body fat has 3600 calories. So every 4 days you should drop a lb. And you should be down ~7lb total.
If the caloric deficit is to big your body kinda “freaks” and holds on to fat. It will try to store as much nutrients away as possible since it thinks you’re starving. Calculate your basal metabolic rate(there are calculators online) Once you factor in your exercise, I’d try and sit around a 500-1000kcal deficit. That’s 3500-7000cals or roughly 1-2 pounds a week. As long as you eat enough protein and lift you should be able to lose mostly fat.
Sometimes when you have a ~1000 calorie a day deficit (it’s a large % of what you used to eat) your body slows your metabolism, so if you’ve lost anything in the realm of 5lbs I’d consider yourself on course. (As an aside for the girls, your body obviously goes through cycles that can raise and lower the amount of water in your body, consider weighing yourself month to month to get more accurate results)
