hi. my baby is now 10 months old. i put all my weight on after i'd had her as my body stored fat to ensure milk was there. i had to forget about the weight loss as by baby's wellbeing had to take over. when i ate less, my milk supply went down.

now my supply is there no matter what and im only feeding her morning and lunch time, (i give her formula before she goes to bed) i have just started the 5:2 diet. im trying to find out if i need to maybe increase the calories on fast days by 200 or something?

going on a diet is one of those things that has to go on hold when you're breastfeeding a young baby unfortunately. it doesnt last forever though.

I have been doing 5:2 for about 11weeks. Ebf baby who is now five months old.
I take my vitamins every day and have lost 1st 9lb.
Baby is thriving.
My BMI has gone from 25to 21.
Not for everyone but I have found it easier than"healthy eating".
You will lose weight (probably) just from feeding.
I did with DC1.

I wouldn't. Really wouldn't! I put most of my weight on when I was breastfeeding because I was so tired from lack of sleep from having a new born + having constant cluster feeds for the first 6 months!

Seriously just keep to a safe, even calorie count with reasonable exercise. Taking your dc out in the pram etc. You're nourishing your baby through your milk, why would you want to jepordize that??

Micheal Mosley did a web chat on here in which he said he would not suggest breastfeeding mothers fast, I think his reasoning was that there is already enough demands on your body.

I totally get where you are coming from, I am trying to lose my baby weight while breastfeeding too but at only 8 weeks could you not give yourself a bit more time? Another month or so? My weight is coming off now with reduced portions, less carbs and running with the C25K app.

Marking place - bf'ing 10 week old and have about two stone to lose. My appetite is huge though ��

No. Drastic dieting is not for breastfeeders. You are feeding your baby solely and therefore you need to make sure you have at least 2000 calories per day. If you stick to that you should find that you can lose weight naturally as you should use up about 500 in milk production each day. To drastically reduce your calorie intake will reduce your supply and cause problems when your baby is trying to feed. I breastfed for 7 years in total with my children and noticed when I was ill and not eating that my milk supply dropped a lot.

How is it going lucywiltshire, Doigetastickerforthat? I'm thinking of giving it a try. Do you feel tired on fast days?

DoIgetastickerforthat - thank you - I am so glad to hear from someone in my situation who is doing it. I intend to have brekkie and supper so won't be going too long between eating. I am also going to do Mondays and Thursdays. I am excited about it - can't wait to look like a woman and not a hippo

I've just started the 5:2 (2nd fast today) and am currently breast feeding a three month old. I have upped the calorie intake to between 7 and 8 hundred on fast days and making sure I don't go longer than 18 hrs without eating. Plenty of fluids and ensuring that the food is nutrient dense, I think, will ensure no drop on milk quality or quantity (of anything it'll improve as I'm taking far more care over the nutritional side of things than I usually do).

I'm also, from next week, going to fast Mondays and Thursdays so that there is a good break between each fast and then make sure i'm having my full calorie load on non fast days. Honestly, I can't see it having a detrimental effect on bfing, women throughout history have nursed their babies on far fewer calories but we're all here to tell the tale.

Thanks very much breastfeedingquest. I plan to have two boiled eggs, smoked salmon and ryvita for breakfast, fruit for lunch and then chicken/white fish/prawns with stir fried veg for supper. This would be within the 500 cal guidelines of the diet and as I will be eating my usual big portions of everything on the other 5 days of the week I hope my milk will be fine. If it isn't I will stop immediately. I have put on so much weight I am sure everything will be fine as I have enough body fat to make my milk rich and creamy and plentiful (I hope).

You are right to be worried about dieting and breastfeeding. Breast milk production is a smart mechanism. It will pull all the necessary nutrients out of your stores if they are not readily available from foods you eat. So I wouldn't be so worried about the quality of milk. It won't be affected for some time. It is your health, health of your skin, nails, hair that is going to be affected if the diet is severe.
You may, however, experience some drop in milk supply. It really depends on the characteristics of your body.
I have a page on my site where I compiled all the important info on breastfeeding diet and nutrition. Here it is, if you are interested: www.breastfeedingquest.com/breastfeeding-diet.html It will give you a good idea about the nutrients requirements for a breastfeeding mother.

Thanks for the kellymom link - very interesting. I don't want to fast particularly but want to lose weight for various reasons and this diet seems a healthy one in terms of cancer prevention etc.

What does TDEE mean?

I am hoping that my calorie intake on the two "fasting" days can be higher because I am breastfeeding!

I wonder if you can modify your 'fast' 500kj day like weight watchers do for breastfeeding women -or give them more points.

What is your TDEE?
Maybe try something between the two?
Or plan three very healthy low cal dishes two days a week. Spread them out so they don't interrupt milk supply?
Not sure really don't think you can follow 5:2 exactly but a modified version might work for you?

i know nothing about breastfeeding . if your boyd is producing milk for your baby, why would you fast for 2 days?

this cites some research - not sure how valid it is

I am really keen to start this diet with DH as need to lose the 3+ stone I put on during pregnancy but am breastfeeding 8 week old DS so am worried about effect on my milk. I have bought the book but no mention of breastfeeding so does that mean I can safely do the diet without it either reducing my milk supply of making my milk too thin/watery?
