Best way to lose bodyfat?
I'm 39 yr old female, 138 lbs, 27% bodyfat, 5ft 4in tall - I'm currently working with a trainer 3x a week and doing cardio 2x a week. I'm eating between 1600 to 1700 calories a day and burning 4100 calories a week through exercise (according to my HR monitor). The last 3 weeks I haven't lost any weight or bodyfat. I'd like to get down to 20% bodyfat as a goal. What should I be doing differently?
