TooMuch - nothing wrong with being meat-heavy! But - your menus are also, I think, too carb-heavy. The risk you take here is that you're eating high fat but also reasonably high carbs, which will make weight loss difficult.
You have had:
carrot and hummus
chilli - with kidney beans, onion, tin of tomatoes and guacamole
bowl leftover chilli with a little leftover guac
sausage casserole - with red onion, tin tomatoes and carrot
half bowl of leftover chilli
1 beetroot, and 3 small cold meat balls (carb 7 per 100g)
If you add all these up, you could be eating a lot of carbs. Did you make the guacamole or buy it? If you bought it, did you check how many carbs?
Onion is carby - use shallots instead, and beetroot is really carby, at 9.5g carbs per 100g - which is why it's not on the allowed list! Sorry to pick your menus apart 
I know that wasn't the original problem that you were asking about!
You need to eat veg from the allowed list, and to focus on those that are 3g carbs or less.
In terms of the bloating, you need to drink more water - you should be drinking at least 3 litres.
Re going to the loo, more fat could help you, along with the water. Other things that can help include strong coffee (preferably black, so you're not adding carbs from milk!), and - apparently - a high strength vitamin C tablet. Others have talked about using linseeds/flaxseed - but I've never used this so can't say if it works or not. (Actually I wouldn't know about any of them, as thankfully constipation has never been a problem for me).
One final remedy, which goes against Bootcamp rules because it contains artificial sweeteners, is Thornton's Sugar-free chocolate and/or toffee. The polyols (sweeteners) have a laxative effect. You have been warned ...
