By the time I handed in my thesis last November, I was heavier than I'd been in my adult life without actually being pregnant or having just had a baby. However, I was fairly philosophic about it - I figured that writing a thesis was not unlike gestation and delivery, really. But one still has to do something about that
Part of the key to tackling this, like it or not, is measurement, in some way or another. I really dislike being overly attached to either scale weight or absolute body size, though both the scale and measuring tape can be useful tools for evaluating progress - I just think it's important to make sure that they are servants rather than masters. I much prefer a process oriented approach - time spent in activity, intensity of effort, weight lifted - things that can support the development of long term, sustainable habits that become part of a healthy lifestyle.
I also don't love having to measure food, but at least in the early stages, it can be a good reality check that leads to more mindful eating habits. The mosaic above is a composite of the different measuring tools I used - my son was a good sport and was my model, to spare you all a picture of my own belly - and in fact I never used a measuring tape at all - if I have to pay attention to that particular parameter, I'd rather just use my clothes.
