Can't predict that. : Your total body fat- plays a major role here. Exercise alone will not normally give you flat abs. For a flat abdomen eat healthfully ; be physically active. Calories burned must > calories consumed. To tighten ab's do crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge ; “bicycling” exercise on your back. Engage in regular aerobic exercise

Depends...: Weight loss occurs at different rates for different people and depends on how much weight you have to lose to reach a healthy weight. In a controlled environment like the "biggest loser" ranch you might be able to lose 10-20 lbs. Per week. Realistically though, 2-5 lbs per week using a high quality meal replacement program is what you should expect. www.dhcaz.tsfl.com.
