I agree - it is not unreasonable, but you have to buckle down, and do it the right way. Make sure you are eating whole foods, low in sugar and fat, and regular small meals 5 -6 times per day. Exercise helps with toning, calorie burning, and energy, but diet is really 80% of your body. Give yourself a cheat meal each week, and eat INTUITIVELY. Don't starve yourself, that just leads to binge eating. Good luck!!!
