Josie, I peaked at your fitday account (good job on starting one btw ) What first pops to mind is that there doesnt seem to be any veggies on your list. You should be getting 20g of carbs from green veggies (2 servings a day or one serving and a cup of salad). Also the calories are VERY low; low carb and low calories does not work. You need to eat more; 10 to 12 times your body weight. Try upping those totals with more fat, butter, olive oil. sardines, mayonnaise, salad dressings, skin on chicken. You'll find things taste better and your WOE is much easier to adhere to

As for the snack difference between the US and the UK, I believe Jello is Jellie (gelatin) and cheese strings are just cheese that is prepackaged into string pieces, it's generally cheddar or mozarella. I dont' buy those myself, I find it more cost effective to buy large blocks of cheese and portion them out (we do go through a lot of cheese in this house )
