Good luck - you are exactly a week behind me, I started on Attack last Wednesday and am just moving into Cruise phase.
If you read my diary for the first few days I planned so much food, I think everyone thought I was bonkers, I'd even meticulously planned my snacks!
Make a real effort with your food, I think it is really easy to be sucked into eating bland food but this doesn't need to be the case. The more you can do with the meat/chicken etc the less likely you are to get bored.
A few things I found useful - grill a chicken breast (boneless) cut it into slices or cubes and snack on that if you are hungry (I am forever shoving food into my mouth without realizing it). I tend to drink my water warm with either fresh mint leaves or grated ginger - it gives a flavour to the water and the ginger has an added diuretic effect! Personally I'm not a yoghurt eater but I've made sure I have at least one fat free yoghurt a day - I save it until evenings usually because I find that is my snack time when I want something sweet and that does the job (not as good as chocolate but beggars can't be choosers).
Drink, drink, and drink some more.
If you are hungry eat (and drink). I stocked up with loads of things I could just snack on - first weeks food cost me a fortune but it needed to be done. Once you are in ketosis you will find the continual snacking will stop featuring so highly!!
Just break through those first few days, it isn't easy but once you are on the other side then it becomes much easier and the need to continually eat subsides but continue drinking!!
Wishing you masses of good luck. I have five and a half stone to lose and am thoroughly ashamed of my weight but after just one week I am so much closer to breaking down into the next stone down which is unbelievable really considering I was only a couple of pounds off going into the next stone up. I am aiming to lose half a stone at a time and will reward myself each time!!
