Personal;ly my advice if you want to loose weight fast dont breatfeed because you will keep producing forever if always pump milk. My advice is take something to increase your metabolism cut down on strachy food (rice, potatoes, pasta, bread etc cause they turn into sugars) dont exercise till after your 6 week pospartum appt with drs okay(like pushups/situps/cardio) it can burn you out and alos cause hemoragging. So heres a list of things before 6 weeks and healthy weight loss is 8-10 lbs per month
power walk(jog slowly for 5 mins and the walk 5min then jog for 5 mins etc)
eat full balanced meals take vitamins
take something to increase you metabolism!!
Etc
