All relatively good food choices. It's not really about what you eat, but how much of it you eat. Find your BMR and generally slowly add (bulk) or subtract calories (cut). Sweet potatoes and veggies are magnificent because they're rich in many different micronutrients and fiber (come at me, IIFYM people). For me, my BMR is around 2200 calories. If I want to cut, 500 calories under 2200 will make me lose 1lb/week. Play around with your numbers because 500 calories +/- isn't the sweet spot for everyone. Start off at a +300 calorie trend your first couple of weeks and monitor your weight and body composition. If you're not getting any bigger, add more calories.
