I'm only 5'1, and all my 20s and early 30s I was 56-58 kilos. Always loved running, wanted to lose a few kilos, but never really could. Had a baby 2.5 years ago, put on 13 kilos for that, breasted for 2 years. First year of giving birth I slowly got back to my pre pregnancy weight. Now, I'm 50 kg. Had a stressful time going back to work when my daughter was 10 months, and that stress lasted about 4-5 months. I lost quite a bit of weight then but it hasn't gone back on. I eat the same as before, if not more, and I exercise less than before having my daughter. What's going on?
