don't worry over daily bur look at the long picture I frequently spike well over but try to keep weekly where I want it to be thee is an excellent weight log (hacker diet online) wher if you are like me and weigh daily will show you that you are actually losing or gaining. It also helps to keep your metabolism keyed up if you go under and then over so that it does not get used to a regular figure day in day out . Hope this is of some help!
