Is it possible to lose 4 lbs in one day or do I need to change my scale? It's supposed to be a good one but I just can't believe I lost 4 lbs in one day.

I heard a guy saying he can drop 5 pounds taking a number 2

But seriously, I understand that is possible. Good job!

Just enjoy the ride. There is no right or wrong amount of weight to lose in a given time frame.

I call those "whooshes". You aren't losing for a while, or losing your normal 1-2 lbs a week, then WHOOSH. 4 pounds It happens.

Although I haven't had a whoosh in a while

Babbs you're probably right I was the same weight for almost two weeks

Totally possible. Enjoy it!!
