Yes, this is absolutely a thing for some people. Some people lose weight rapidly while breastfeeding, while others are unable to lose until they wean. Good luck, and I hope the latter is true for you!

A breastfeeding group I’m in had this discussion recently. Some people lost all the baby weight breastfeeding and some didn’t until they weaned. My little sister was under her pre-pregnancy weight by eight weeks PP, while I’m here at 5 weeks PP holding on to 18 lbs (yeah, all that isn’t coming off in 3 weeks).

I have noticed that if you had a great workout regime BEFORE and during pregnancy, then the weight starts to come off after baby slowly but steadily. However, if you did not, then it comes off after weaning. Weird! For me it was the latter. I did work out while BFing but it was extremely hard to get even 1-2 lbs off in a month. Ugh!

I would suggest that you actually not worry about the weight until you have weaned off the LO completely. Weighloss is basic math…. calorie deficit is required. So don’t hurt or change your diet until LO’s still counting on it. smile

queenie8119 :  Anecdotally disagree with this. I was really fit before getting pregnant, still worked out a lot up until 28 weeks, and then walked tons as exercise during the last trimester, and the weight isn’t falling off while my little sister doesn’t work out at all and lost all the baby weight by 8 weeks.

MRSsrm85 :  This is also what has been true for my friends and me. Those who didn’t work out at all pre pregnancy lost all their baby weight and more from breastfeeding (I think that extra 500 calories burned feeding made a difference for them) but someone like me, who has worked out all her life), going to a much more sedentary life of sitting and feeding all day long, did the opposite. The weight didn’t budge. I can’t comment if after weaning I would have lost it because I stopped feeding my daughter at 12 months and was pregnant with my son when she was 12.5 months. I’m still breastfeeding him but this time the weight has come off because I had to massively reduce my calorie intake (he is allergic to dairy). Without cheese in my life, I lost 18 lbs in 8 weeks (when my son was 4-6 months).

mrsknc :  One of my friends worked out regularly before she got pregnant but she wasn’t a triathlete or anything like that.  Her son is 1 year old and she’s just now starting to wean him.  She didn’t lose any weight at all by breastfeeding, even though she’s been back in her normal work out routine for several months.  She said she’s still about 20 lb above her pre-pregnancy weight and is really frustrated.  She also eats pretty clean so it’s like her body is hanging on to every single calorie.  Hearing that makes me really nervous as I love to work out and have a lot of body image problems to begin with.

I think it has to do with hormones, and it is hit or miss.  I went back to my pre-pregnancy weight naturally while breastfeeding.  When I stopped at 14 months, my hormones went crazy and I had mood swings and gained 10 pounds.  My menstrual cycle, which had been normal, got weird for a few months too.  

My daughter is 20 months now, and I have about 5 pounds to go again to get back to pre-pregnancy weight.  (And I was probably 15 pounds overweight to begin with, so I should really lose like 20 pounds.)  I think I needed to adjust to needing fewer calories, and also the hormonal changes.  I think any changes in hormones can trigger weight loss or gain depending on circumstances, so it could go either way.

Completely disagree that if you worked out before and during pregnancy that will translate to weight loss during breastfeeding. I was in great shape before pregnancy and worked out until the day I delivered. I only gained the minimum amount of weight recommended and I’m 6 months pp and still hanging on to 10 lbs. I’m certain I won’t be able to lose it until we wean. I’ve actually noticed the more I eat, the less I weigh! I’m sure my body is hanging on to extra fat reserves to ensure sufficient milk production. Frustrating but I’m so grateful to have a plentiful supply!

I gained 40 pounds while pregnant. Lost the first 30 pretty easily while breastfeeding but I’m hanging onto the last 10 pounds and no matter how little I eat and how much I work out they are not going anywhere. I am down to 2 feeds a day.

I heard lots of anecdotal reports of the last of the baby weight coming off within a year of fully weaning, so I am hoping that’s how it goes for me.
