When I went to the OBGYN last week they told me to go on the SouthBeach Diet. I told them that my milk seemed to decrease whenever I reduced my calories- even with as little as 100 calorie change. I started the diet with phase 2 becasue I really do need to loose the weight (currently 191 - hoping to be 150 again someday). I reasoned it as eating the same amount of calories with healthy food is better then eating a ton of sugar and fat. I have been on it for 2 weeks and noticed that my milk seemed to be going down. I added some calories back in thinking that I cut too much but my milk was still low and getting lower. I have now stopped the diet and still low supply. I am drinking lots of water and mothers milk tea. I have been pumping all day and the most I am getting is 2 oz. 2 weeks ago i was making about 5 oz. Is it possible that I am loosing my milk?
