If I aim to walk for to hours every day in morning will I lose ten kilos? ?

Mia asked:


I had my forth baby 6 mnths ago and unlike with the othr three where i lost all my weight straight away, I have not been so lucky this time. I do eat properly maybe a little bit too much. But I also breast feed full time. I would love to hear of any tips for quick weightloss before xmas??
