It's not about dropping a ton of calories quickly, it's about smart healthy eating with tracking said food.
Drop too quickly sure at first you'll see a lot of progress, but then your body will go into survival mode and you'll flat line results wise.
Example: A guy who is 25, 5'10 and 211 pounds requires around 1859 calories a day being sedentary to lose weight. If you eat lean and healthy that's a good amount of food.
My best suggestion is run your numbers through a calculator. Eat to around that limit each day, and weigh yourself each day in the morning. Divide to get your average for the week, and then run it for another week. Lost nothing? Reduce by 100 to 200 calories and take the average again. Small adjustments with each change, and as long as progress is happening even if it's 2 pounds lost, then it's progress. If after awhile you stall again, a tactical refeed might be useful.
Getting cut or losing weight doesn't have to be brutal, it just has to be done smart.
