I weigh myself every morning and track it in a diary online. I find I know exactly what food causes the most weight gain even though I do really well the rest of the day (for me, it's pasta and American biscuits with butter, so those become very rare foods I eat).
Laura, I think you might be setting too high a goal for your second day on WW. Weight fluctuates. I do this occassionally on my scale: get on butt naked (scary sight) in the morning after I wake up and go to the toilet. I get my clothes together for the morning, do a quick stretch then go back and weigh myself- the difference can be 1/2 to 1 pound (or more); and that's in a space of 5 minutes or less.
When you set goals, you need to make sure they are SMART goals: Specific, Measurable, Attainable, Realistic and Timely. Ten pounds the first week in WW is highly unlikely. Three may be a bit more realistic. One definitely is. Aim to lose your weight in a reasonable amount of time. You've got 9 pounds to lose: 3 months is a realistic goal (9 pounds in 12 weeks= 3/4 pounds per week). Mine happens to be:
- Long term: 40 kg, of which I've already lost 15; leaves me with 25kg/55 pounds to where I would feel very comfortable with my weight (145); 135 is where I would feel happiest (though this is subject to change daily).
- Medium term: 9-10kg by 5 September (my birthday), which puts me at 82kg.
- Short term: 3kg by the end of April (that'll take a 10kg block off the scale at the gym).
Good luck and don't lose motivation. Remember, whatever your reason for losing the weight, you can do it. Don't be discouraged in less than a week on WW; it'll come off if you stick to your plan.
Cheers.
