As a former Weight Watchers receptionist (and WW lifer), I know the drill. Get on the scale once a week. No more, no less. Don't freak out over the number for any given week. Your body doesn't always process things in a timely manner. Well, I know all that, but I am still in a very wearying mental battle--more with myself than the actual instrument giving me the numbers I don't like.
Despite all advice to the contrary, I hop on the scale every morning, and I have for years. I also am very aware that what I eat today likely will not be reflected tomorrow morning, as one's body often takes 2-3 days to process high fat or high sodium foods. And Sunday evening was full of both of those offenders, as well as some red wine. But I was so VIRTUOUS yesterday, and had run over 11 miles between Saturday and yesterday, that I was convinced this morning's scale announcement would be a pleasant one. No such luck--in fact, it was 0.2 pounds UP from yesterday. And that would be completely acceptable if the entire reading weren't about 7 pounds more than I wanted it to be. I seem hung at this point. I am going to have to incorporate some strength training back into my routine, no doubt about it. It will help my sluggish running AND my sluggish metabolism, I hope!
Happy running, happy strength training, one and all!
