With the water thing, once I started drinking water (not diet coke, and not no added sugar squash!) I found I was so thirsty. I drink gallons, probably at least 3 litres a day, which tallies with that list BIWI. and I feel supremely better for it. I now crave water, and can tell if it's hunger or thirst. Nne times out of ten, it's the latter.
I also eat lots of avocado and salmon, and use lots of normal sea salt, which I think is why I haven't had the electrolyte issue that some people report.
I also think it is really important to understand the science, so you get why skimmed milk is a disaster, but clotted cream is fab, for example. It makes choosing things in restaurants so much easier. you also then start to understand why low fat products are rubbish. Replace the delicious, satisfying fat with sugar. Ridiculous.
Also thought your initial instructions to weigh a veg portion and to see what sort of carb count you're looking at is also arable advice. Veg is not entirely unlimited for bootcamp.
On another note, has anyone found themselves demonising pasta in their head? I look at it and just think it is a pile of nutritionally dead pap! Cannot believe how much of it I used to eat!
In that link BIWI posted, they talked about nutritionally dense food. That really rang bells with me. Love that as a guide for my choices.
