6lbs during induction is good :-)) What was it you added to week 3 that you weren't eating before...maybe you've found one type of food that your body just can't cope with at the moment??

During induction and found I wasn't hungry like I used to be at all...you have to make sure you're getting enough fat (this was quite hard after a really low fat diet previously) and protein. What's a typical days eating for you like??

I always stop losing weight when I add the atkins bars... I know its not the best idea but I usually stick to 20-30 carbs a day no matter what.

I guess i added the atkins bars, i am going to cut them out. I should start counting calories as well!
Usually a day is like:

Breakfast-Atkins bar,

Lunch- Tuna salad or cheese/ham roll ups

Dinner- Cheese omlette & bacon or Chicken or steak etc with some brocolli, onion

Snacks: Sugar free jelly, Salami sticks

Drinks, the odd atkins shake, herbal teas

Atkins says that if you stall or gain, you need to make sure you're not eating hidden sugars, cut out on the Atkins products, and make sure you're not eating too much cheese or nuts.
If you're still on Induction, you need to make sure that at least 12 of your 20 net carbs are coming from salads and veggies. From your list above, it doesn't look like you're eating enough veggies. Make sure you're drinking enough water!
Good luck!
