Just started atkins , and am in the induction phase , what i dont understand is all this talk of processed food etc etc . If carbs are all that matter then what diff does it make ? If i am aiming below 20g of carbs a day what does it matter what i eat aslong its below that level .....

For example i have salami in the fridge the pack is 250 gram total and has 1gram of carb per 100 grams so the whole pack is only 2.5 carbs , why does it matter if its processed ?

Also what is this flu phase everyone goes on about it but doesnt explain what it is in any clear definition ???
