Welcome @Bloodylovepotatoes
Hello everyone. May I join? Two weeks into low carbing and thus far I'm finding it a challenge - didn't lose any weight the first week so I decided to start tracking my calories. No bloody wonder I didn't lose weight as I was eating about 1800 a day! My BMR is only around 1400 so really I can't be having more than 1200 which is really difficult even on low carb.
We don't count calories (or carbs!) on Bootcamp. Eat enough to satiate your hunger - don't go mad but certainly don't deprive yourself. This is not a WOE which is about starvation!
Anyway, by and large last week I stuck to that and have dropped 2 lbs
That's great!
But I'm always hungry. I see so many people saying that a bowl of greek yoghurt or whatever gets them through to lunch - I have a bown of FF greek yog, 10ml of double cream and some berries at 9 and I'm already starving. Can't understand how people say you don't overeat on this diet - I could eat high fat foods til the cows come home!!!
This suggests to me that you're not eating enough fat or protein - and that you're not quite fat-adapted yet. When we low carb we're essentially keeping our blood sugars level, which means the three key hormones (insulin, grehlin and leptin) are in balance. These hormones are what control your hunger (not an empty stomach!). Once you're fat-adapted, your body isn't using carbs for fuel, and your blood sugars will be more stable - and your appetite between meals will greatly reduce.
One thing to be aware of, however, is that many of us snack out of habit or because it gives us emotional comfort.
Anyway, I'm sticking with it for the time being. Any advice or words of wisdom welcome
See above! 
I know some people don't eat berries at first but I have got to otherwise I get severely constipated (yes I drink enough water, yes I eat enough veg, yes I have linseed and magnesium!). I am aiming for under 50g carbs a day. Nice to be here!
Hmm. Not sure this is really true - think this is a justification for eating berries! And as I said above, there's no need to count carbs either - just follow Bootcamp rules.
One thing you haven't said is how much you currently weigh/how tall you are.
