Don't do it.
Over-weighing yourself only causes you to overthink what you're doing. Just do it once a day at the same time for most consistency and remember only the long term weight changes matter.
Your weight will bounce up and down through the entire day and a super precise scale will simply wind you up.
Ah ok, will take your advice on that. Sounds like my scales are accurate enough then. But I'll be happy once I notice my stomach flattening out. I know this isn't the sports arena, but would you recommend I do daily sit ups to reduce stomach fat?
