The weight simply won't go away once you stop taking Zoloft. Based on your current weight you're allowed about 1800 calories in order to maintain your weight.
At your current weight of 155, each mile you walk burns 85 calories. If you were to walk 6 miles a day you would be burning 3570 calories a week. 3500 Calories = 1 lb loss.
However, in order to have a 1 lb a week loss you must not exceed 1800 calories a day which is a lot of food if you avoid high calorie foods like cheese which has 100 calories an ounce.
In summary, maintain 1800 calories a day and walk 6 miles and you'll lose the weight in about 34 weeks. If you can walk more than 6 miles a day that would reduce the amount of time to reach your goal.
I suggest you purchase a Pedometer to measure miles. I've lost 70 lbs by walking in the past 15 months. I need to lose another 25 lbs in order to reach my BMI. Walking to lose weight is much better than dieting.
