HI MG...

Good on you for starting your weight loss, it can be really hard, but try not to loose sight of your goal... you will possibly have weeks of plateu or weight gain, but as the others have said, its how you feel and also your measurements that will give you the better idea of how you are going

The thing that i always do when i am starting to loose weight (or trying to) is i rule up a chart...i divide it into 7 days and the columns into sections as follows
*breakfast
*snack
*lunch
*snack
*Dinner
*snack
*Exercise

In each box i write what i consumed for the day (including drinks at those times and if the food has a Kj content, like on a coke bottle or i estimate using the values i know (like slices of bread salad values etc etc) and total them up for the day
To loose weight you need to be consuming less than 7000KJ a day...its amazing how quickly these things add up...

AND if i actually have to write down what i am eating and put a value next to it, it really makes me think about whether i still REALLY need that food i am about to put in my mouth.

Its suprising where you get a lot of your Kj from, and tbh i had no idea what my problems were until i did this for a week or so...
Also if you leave this chart in an area that your DH can see it, it may help motivate you not to eat badly as he can see what you are doing (and see how well you are doing too )

Weigh yourself ONCE a week only, do it at the same time of day and on the same day, dont think about it for the next 6 days.
Get a tape measure out and measure the widest part of your upper arm, your bust, your waist (the narrowest bit), your hips (the widest bit) and your thighs (a good spot is where your fingertips stop when you hang your hands down...
If you are not to embarrassed about it (i always am) get someone else to do the measuring for you as it will be more accurate (and they can celebrate with you when you get results)

HTH

ETA: i drink things mixed with soda water so that i am having a fizzy drink without the Kj... another option you may be able to consider
