I weigh every morning and record it in a spread sheet, where I also track my progress week to week and month to month, charts and everything!

It has helped me to understand and accept daily fluctuations, and on a gain day, my chart is a good reminder that I have made progress overall. Plus, it bugs me when I don't have a data point for everyday, lol.
As with choosing an eating or exercise plan, you have to do what works for you. If it's motivating to weigh everyday, do it! If not, try something else
