How do i lose about 10 -15 pounds in around 3 months to show my abbs?

Is possible: To lose approximately 12 lbs in 12 weeks, one needs to have a net loss of 1 pound per week. One pound is ~3500 calories. Using round numbers, a net loss of 500 calories per day would equal a loss of approx 1 lb per week. Would combine altering intake to leaner more healthful foods (decrease caloric intake) and start physical activity- moderate level 30-45 min/day (increase calorie loss).
