I have good news for you! You can defo lose weight when breastfeeding and use breastfeeding to assist the process!
Heres the science bit........
A woman usually requires about 2000 calories a day to maintain her weight. Breastfeeding uses about 500 calories a day. So a breastfeeding woman needs about 2500 calories a day to maintain her weight.
So if you are breastfeeding and want to lose weight, aim for the normal daily intake for a woman of 2000 calories (note tho that some women require slightly less calories so the exact amount may vary between 1800 and 2000 calories for you to see some weight loss, you may need to experiment with this).
If you stick to 1800-2000 calories a day you'll see a loss of about 1lb a week, as you will have a deficit of about 500 calories a day so your weight will start to come off. You don't want to lose any faster than this though so do not be tempted to cut your calories any lower than 1800-2000 (as it may leave you feeling tired and a fast weight loss means you are less likely to keep it off).
After both my dd's i waited till about 12 weeks before limiting calories to a normal daily intake of 2000 a day. Both times all my extra baby weight (about 2 stone each time) came off. it does take about 6 or so months tho!
Plus if you do weight loss this way there is no detrimental effect to your milk or to baby as you remain eating a diet as healthy, balanced and varied as you would normally (ie. if you were not on a diet as you would be eating 2000 cals a day anyway to maintain weight even if you weren't feeding iyswim!).Although counting calories is a bit of a nuisance it is worth doing as you can see the weight coming off and you do not feel deprived as you are eating about the same amount that you will have done before you got pregnant.
My doctor explained all this to me, and i will be following this advice again after my 3rd (due in 3 weeks). As expect i will have another 2 stone to shift again..........
