Dreamfields pasta is actually really really delicious, but serving sizes are deceptive and it's 5g carbs for a tiny side portion. In the past when I've dine Atkins I've bought too many replacements - low carb bread, chocs, pasta & etc and it has always been my downfall because I eat too much of it and while this stuff may be low carb compared to the real thing, it still all adds up. Nowadays I mostly limit myself to 1 Atkins bar per week, and that's the plan for a while.
My advice on getting started would be not to buy any 'replacement' products - except maybe 1 Atkins bar to have a little bit of every day if you think a little choccy bite will help - for at least the first 2 - 3 weeks. After that try and restrict yourself to one thing per week, then you'll be able to tell if it stalls your loss.
When you cut your carbs you go into something called ketosis which is essentially the body's starvation mode. Funnily enough people who are actually starving don't feel hunger. Cutting out carbs tricks the body into giving us the same effect.
That's not to say you won't be hungry. The first three days as your body let's go of it's carb stores you may well be ravenous, and you'll have hungry days even far into the diet. The good thing is, when you're hungry, eat. Have some cheese, or ham slices. Any high protein low carb food will help fill you up, whereas eating carbs would just make you crave more.
Have your tea as usual, but use sweeteners like candarel, not sugar. Ideally you would use cream in it, but if you use milk just add it to your carb count. Look at the section on mims, which are a good bread substitute and have a lot of fibre in which is much needed on this diet.
You will be fine xx
