We have found trying to time weight loss to be a) totally ineffective and b) really stressful and with the capability of messing up people's sways.
This actually happened to me! With my 4th boy I was so sure that actively losing weight would sway hugely pink that I tried to take a month off and regained weight to relose, only to get pregnant the month I was regaining weight! And this has happened to several people. Additionally, when you've lost and then regained weight, your body can see this as "improved condition" and that may sway even MORE blue. Please just lose what you can, when you can, if you can, and hold steady instead of losing too much. We get by far best results that way.
