Thursday is the day I have established as my weigh-in day. I only weigh once a week, the same day and time. It will be first thing in the morning. If you're weighing more than once a week, I've found that for most gals it is either discouraging or encouraging and can then lead to sabotage!
Just focus on one day at a time and going to bed with a stomach that is near empty and will be ready for food in the morning. I do not suggest skipping breakfast on a regular basis. Our bodies rely on the "jump start". It is best to eat small enough portions at each meal allowing time between the meals to burn the calories you've consumed. So obviously if I had wanted to eat dinner I should have eaten less at lunch!
