I understand, but you should try and go a little longer. You will benefit more in the longer term.
The reason i'm saying this is because, the prime objective, isn't to lose weight? Its to live a healthy life...right? Take this for eg, If you drink a litre of water just before you weigh yourself, it will register on the scales...but its just water...you see what i mean?
Weighing in can be inacurate sometimes, because everyones body is different, some bodies retain more liquid than others - and this varies from day to day.
If you watch and learn about the foods you should be eating, then the weight will naturally drop off, with no effort whatsoever.
Although I do think it's an effective way to motivate yourself...i understand that when you weigh yourself and you see that you've lost weight over night it's mentally motivating, but the longer you wait to weigh yourself, the better you program your body and mind to be good for longer...you see what i mean??
