I think this is a great way to keep yourself accountable and on track for your goals.
However, in my experience daily weight ins usually lead to driving most people INSANE!
Like Troutman mentioned above your weight can fluctuate daily for a number of reasons like water retention, time of day or more importantly, stress levels. I own a private fitness studio and work with clients every day for weight loss and the first thing I tell them after we do their initial assessment is to go home and break their scale and NOT weigh themselves unless it is their scheduled monthly assessment (weekly would be alright too, but we do monthly).
The reason I do this is because I have had (and still do have) clients that continue to weigh themselves everyday and they come in stressed to the max because they are looking down at that scale every day looking for losses every day and they are stressed because they are not seeing huge losses like they would like to. And one of the reasons they aren't seeing losses like they want is because they are stressed the max about the scale every day!
All that stress works AGAINST your goals by flooding your body with a TON of hormones that don't like fat loss and will actually fight to hold onto that fat in your body.
Now if you're simply doing it to keep yourself accountable, then thats ok, but I would still recommend moving to at least weekly...or MAYBE 2x per week if you feel you need to.
Anyways, thats just my 2 cents from my experience with my clients
Keep up the great work everyone and I'm looking forward to reading about your progress and reaching your goals! I hope to help however I can in this forum
