There's nothing wrong with daily weighing
so long as you can keep it in perspective (like the posters above
). Studies have shown that daily weighing is associated with better long-term weight loss and maintenance. Why? A lot of us have a problem with denial but it's very hard to kid yourself about what you're doing when the evidence is in front of you every day. And it's a lot easier to deal with a little gain right away than a big gain later on.
If you're going to weigh every day, think of it as learning how your body reacts to hormones, weather, sodium, carbs, exercise etc. It never should be a measure of self-worth.
