If people told you to do something because they think that it will be better for you, say them to get the fuck off.
If you feel to fat and want to lose weight but don't want to lose progress, here is what you do:
Keep the program, but don't expect as fast progress on the numbers, they will go up, but slower.
Keep the 1g/pound protein intake
Make an program for you died, there is a lot of things here on the forum. If you want to get lean fast, you probably will cut a lot of your meals and yes, it will have a difference on your lifts.
But if you want to just slowly lose fat while keeping the gains, just a small deficit on the calories will do the job for you.
Think about the died as you think about the workouts. You need to have a plan, you need to acomplish it every day. You don't need to like what you eat as you don't need to like the exercise, the important is the result. To have real results with you died just start taking a few calories off every week.
Start cutting the snacks, them sodas, them fried food.
Than just keep looking to your weight, if you stop losing weight, eat less carbs. (repeat this until achieve desired weight)
