Sorry this was asked so far up the thread, but DH and I went out last night and I got home too pissed too late.
ziggie Here's my diagnosis 
B: 1 small pot ff plain yoghurt
Absolutely fine, as long as you know how many carbs were in this - some can be pretty high for the amount you will have eaten. Also, don't forget, it's dairy. Some of us are less tolerant to dairy than others. Although Briffa says that yoghurt is better than milk/cheese (can't remember why, but I'll find out), it's still dairy
Snack: 2 babybels
OK - but more dairy ...
L: 2 skin on chicken breasts chopped over a salad with ranch dressing and bacon.
The chicken and salad is perfect, especially with the skin on. But what was in the dressing? Was it home-made or from a bottle? Did you check the ingredients? Most pre-prepared dressings have sugar in them and can be quite carby - as well as artificial ingredients. Bacon is fine, but as it's a processed meat we try not to eat this too often/at too many meals.
Snack: ff latte
No way! Way too much milk in a latte. There will have been a huge amount of carbs in this
D: scrambled eggs in butter with bacon, mushrooms fried in garlic butter and 1/2 tsp encona hot sauce.
Perfect - just keep and eye on the bacon, and just double check how many carbs in that sauce. With only half a teaspoon I doubt it will really matter, but it's still something you need to know
Snack: hogbites pork scratchings, chunk of cheddar
Better than a packet of crisps, but the pork scratchings are a bit processed - and just double check the carb count on the back of the pack. If you made your own they would be zero carbs, but I wonder if these have sugar in them at all, as an extra flavouring - which so many snacks do. The cheese is a perfect low carb snack - as long as you don't have a problem with dairy
Drinks: 4 pints water, 5 cups strong tea with dash semi skimmed milk, 1 can diet coke.
Water is good - I don't know how much you weigh so how much you should be drinking a day. Tea is OK, but again, watch the milk. Only a dash is fine, but in combination with the latte that's adding up to a lot - and again, it's dairy. BUT A BIG FAT NO TO THE DIET COKE!
We're aiming to cut artificial ingredients out of our diet as much as possible, so that we're eating 'clean' foods. However, the additional issue with diet drinks is that there is some suggestion/evidence that even though they haven't got sugar in them, our bodies respond to the sweetness of the taste as if they do - therefore they can actually impede weight loss/encourage weight gain. Have a read of this experiment that The Diet Doctor did whilst drinking Pepsi Max
The other reason for avoiding diet drinks is that we're trying to break our addiction to sweet things. If you keep drinking Diet Coke, you're not going to help yourself achieve this.
I know just switching to plain water can seem dull. And if someone could develop/launch a drink that was suitable for low carbers without us having to consume artificial sweeteners, they would make a fortune! Try different brands of sparkling water. They do all have a slightly different taste (Badoit, for example, is quite salty), and they all have different levels of effervescence. Perrier is very fizzy, so it can be more satisfying organoleptically - i.e. the whole mouth experience. If you serve it really, really cold, with ice, lime or lemon slices, it is surprisingly tasty and satisfying.
