Roxy,

Have you considered walking less and spending a few of those walking days lifting heavy things or swinging around a kettlebell, or something else related to building strength?

It seems like you don't have much of a plan. You have a stated goal of losing weight, but not a working plan to get you to that goal. And seemingly, the things you've been doing aren't working.

Maybe it's time to do some reading, find or make a plan that you think is workable for your life, and put it into action. Things (like potlucks with limited choices) are always going to come up, but without a plan or framework--knowing how to eat, for example--we often just start making decisions willy-nilly and end up much worse off in the end.

My intention isn't to sound harsh. It just seems like you've been spinning your wheels with this since the beginning of the year. And you often seem to find yourself in situations where you make food choices that you question (or worse, berate) yourself about after the fact. That's just not helpful or productive.
