Weighing / Measuring food

I have a question..I was to the first information session and am continuing on with my first appt and they have asked me to write down everything I have eaten up until my first appt at the clinic...I even bought some scales..should I be that picky when it comes to the first appt? 

I would prepare yourself now for the journey ahead. Will also show them that you are serious about following the process.

yes- many use my fitness pal to track food- ask your dr if that is ok. mine allowed it

Yes, it's good training. Weighing your food insures you're not overeating. I always weigh my protein, I sometimes try to guess how many ounces my portion is, then weigh it. I usually have more than I think,and have to put some back. If I didn't weigh it I'd be taking in more calories than I was counting.
