Keep your step count around 10k or more per day and you'll be fine. 3000 calories is not high for someone in your position. Eating 3000 calories during the week and 6000 calories on the weekend is where most people run into problems and arrive at the odd conclusion that they need to eat 1500 calories to lose weight. You need to deadlift more btw but I suspect the abdominal fat is an issue there.
