19 June is just about upon us and here we are at Week 1 of a 8 week Boot Camp. Are you ready? 
I'm posting this on the Sunday so that those of you who are early risers can get stuck right in 
I'll start a new thread every week.
It will take me a few posts as I blatantly copy across from @BIWI ‘s excellent introductory posts and I’m doing this on the app which makes it more award.
First off the major caveat: I am not a doctor, nor a dietican. This Way of Eating works for me and has done for many others. I’ve followed BIWI on these Boot Camps for many years and there is a lot of support but if you have any medical issues or concerns, you need to make your own choices. You need to be particularly careful if you are pregnant or breastfeeding (in which case follow Boot Camp Light), diabetic or if you are taking any medication, as you may need to liaise with your doctor regarding dosage. I'll post a follow up post with more details.
The Spreadsheet of Fabulousness is here @FinallyHere is Spreadsheet Monitor and most weeks will post the link in one of the following posts after my OP as I usually post via the App and links can be a bit hit or miss. I'll do a link but it might not work for everyone 
also, if you experience any problems with the Spreadsheet, tag @FinallyHere and she will work her magic on it!
And so to the rules. These are the rules for the first two weeks. After that, we do relax things a little:
1. Eat three proper meals a day
You must eat breakfast. It doesn’t have to be a lot, and it doesn’t have to be absolutely first thing, but you must have something. For the rest of the day, if you’re eating enough food and especially enough fat, you shouldn’t be hungry between meals. But if you are hungry, eat something. (Hard boiled eggs make a great snack). After the first two weeks of Bootcamp we will relax this, but these two weeks are critical in terms of helping you switch easily to a low carb way of eating - and if you start to feel hungry, it makes things much harder! Eating this way will ensure that your blood sugar levels are kept stable, which will mean that you are much less likely to experience hunger. A typical high carbohydrate diet can mean that snacking is a routine part of your day. Once your blood sugar levels are stable, by eating low carb, you should find that you no longer want to snack. But the rule of thumb here is ‘if you are hungry, eat!’. (Just make sure you are only choosing low carb snacks, of course!)
Experienced Boot Campers may follow intermittent fasting (IF) (16:8 or similar) and therefore not have breakfast or another meal but if you’re new to this Way of Eating, wait until you’ve got used to it before starting on IF.
2. Avoid processed foods
Focus on pure, natural protein as the basis for your meals - meat/fish/eggs. Things like sausages, ham, bacon, pre-prepared burgers etc should be avoided as much as possible. You can have them, but just not at every meal, every day.
3. Eat lots of fat
Eating fat will not make you fat. Honestly! But it will keep your appetite satisfied, and it sustains your body’s energy requirements perfectly. Fat does not provoke an insulin spike, unlike carbs which do (a lot) and protein (a little).
Fry in butter, add butter to vegetables, eat salad with a home-made vinaigrette dressing (not made with balsamic vinegar though, as this is too sweet), add mayonnaise where you can (just check the carb count on your mayo first). Eat fattier cuts of meat – e.g. pork belly, roast chicken with the skin on and/or eat the fat off your lamb chops. Absolutely no low fat/light/’Lite’ foods of any kind!
4. Make sure you are eating vegetables and salads with your food
This is where your carbs should come from, and this is non-negotiable. But choose only those vegetables that are on the allowed list, which you'll find on the spreadsheet.
Make sure that you focus on eating those vegetables that are under 5g carb per 100g, and this will ensure that your carb counts are kept low. You don’t have to weigh/count carbs – this is one of the great joys of this WOE (way of eating), but if you’re new to low carbing it can be helpful to weigh your portions of veg in the early days, just so that you know how many carbs are in the sort of portions that you like to eat.
The vegetable carb counter is helpfully colour-coded into green (eat freely), amber (go easy) and red (best avoided as much as possible), which will help you to make your choices.
5. Be careful about dairy (apart from butter, which is unlimited)
Dairy can impede weight loss for some people. If you are drinking tea/coffee with milk or cream, try to restrict yourself to max 2 cups per day. There are a lot of carbs in milk, so if you are having several cups of tea/coffee per day, you will quickly rack up your daily carb count (e.g. 1 medium latte contains more than 12g carbs!)
You may eat cheese but again, don't overdo it. Full fat yoghurt is the best way to include dairy in your diet - but beware, it does contain carbs. You should choose one that’s 10% fat – most of the supermarkets have a Greek yoghurt in their premium ranges with this amount of fat.
6. You must drink a minimum of 2 litres of water per day
The more weight you have to lose, the more water you should drink.
This originally came from www.low-carbdiet.co.uk/ but although the site is now defunct, there are other sources which advise similar quantities of water.
It does of course go without saying not to drink the entire amount in one go: you should spread it out over the day.
Water is essential to weight loss for those who follow a low carb way of eating. The minimum consumed in a day should be:
Your Weight - Litres
140lbs - 2.5
160lbs - 3.0
180lbs - 3.0
200lbs - 3.5
220lbs - 3.5
240lbs - 4.0
260lbs - 4.5
280lbs - 4.5
300lbs - 5.0
320lbs - 5.5
340lbs - 5.5
360lbs - 6.0
380lbs - 6.5
400lbs - 6.5
High levels of ketones in the blood stream can lead to a reduction in ketone production, therefore being well hydrated could aid in keeping the levels low and ketone production ongoing. Consuming enough water can have many other positive side effects, e.g. it aids your kidneys with the processing of protein, reduces the retention of water, helps with preventing constipation, and reduces the levels of ketones released by your breath, which in-turn will reduce breath odour.
However, drinking a lot of water can mean that you also need to keep an eye on your electrolyte balance. You need to make sure that you are consuming sufficient sodium and potassium. On a low carb way of eating, we should eat more salt, so make sure that you are cooking with salt and adding salt to food, if you like it.
Good, low carb, sources of potassium are spinach (raw), avocado, mushrooms, courgettes and asparagus, as well as salmon and yoghurt.
The water is really important - any time I’ve noticed myself stalling, I’ve noticed that my water consumption had dipped. I like to think of it as helping to pee the fat away 
7. No alcohol
Alcohol is the easiest source of fuel for the body to burn, so it will always use this first before it starts to burn any fat - which is why you need to restrict it, especially in the first two weeks of Bootcamp, when we are encouraging the body to stop using carbs for its source of fuel and turn to fat-burning instead.
If you really can't do this - at least try and restrict it to the weekend. Vodka with soda is the best thing to drink. Or Champagne, red wine or dry white wine.
8. No fruit
Really. Seriously. Honestly. None at all. Zilch. Nada. After the first two weeks of Bootcamp you will be able to introduce certain fruits, in moderation, but at this stage fruit is simply too carby. We are also trying to break the addiction to sweet things, so cutting fruit out is part of this process. If you are getting all your carbs from vegetables and salad, you will be getting all the nutrients and fibre that you need.
9. No nuts/seeds
Although they are a good source of nutrition and contain lots of fat – which is great for us – they also contain carbohydrate and, because they’re so moreish, you can quickly end up eating a lot of carbs.
When we move to Bootcamp Light, after the first two weeks, you can re-introduce these, but be careful and go easy. On the spreadsheet, you'll find a nut carb counter, which illustrates just how much they vary in terms of their carb counts.
10. No sugar or artificial sweeteners
Sugar is an obvious ‘no no’, but artificial sweeteners are also an issue. One of the aims of this way of eating is to eat pure and natural foods, so including sweeteners is not recommended. Some people find that artificial sweeteners can impede their weight loss, and there is some suggestion that your body can respond to sweeteners as if they were sugar, by releasing more insulin - and therefore laying down fat.
Given that the aim of Bootcamp is to help us lose our sweet tooth and addiction to sweet things, then it is a good idea to avoid sweeteners altogether in this first two weeks.
That's us off and running. I'll follow up with a few Housekeeping posts but I think that's plenty to get started with.
