As has been stated, proceed with caution. I weigh myself every day, and I post in the "weigh yourself every day" club here in the forums. But I believe I have the right mindset. Actually, I really step on the scale twice a day - once in the morning, and once in the evening. Its sort of amazing to see the scale drop literally 4 lbs overnight - respiration gets rid of a lot of water I guess. Some days, the scale drops a lot from the previous day. Some weeks, I go for 4 days without seeing a drop at all. It doesn't bother me. If I started to see the numbers rising consistently over a week or more, then I start to figure out whats going wrong.
