Pre-Christmas '26 Low Carb Bootcamp - the prep thread

Welcome! This Bootcamp will start on Monday 5 October, and will run for 8 weeks.

I know some of you have done Bootcamp before, some of you have low carbed before, but a few haven’t done either, so here’s a load of information which should give you a good idea of what to expect:

First, a bit about Bootcamp generally:

Bootcamp is a Low Carb way of eating
It’s important to recognise that it’s not a zero carb diet. You aren’t cutting out a whole macronutrient. You will still be eating carbs, except far fewer than you would have been before. Your carbs will come mainly from vegetables, salad and (some) fruits.

A ‘conventional’ UK diet is one that is high in carbohydrates, has a medium amount of protein and is low in fat. What we do when we’re low carbing is to turn that on its head. So it’s low in carbs, still has a medium amount of protein, but is high in fat.

How does Bootcamp work?
Bootcamp is designed to be easy to follow. We don’t count carbs (or calories), and we don’t set a daily limit for carbs. There are just ten rules that we apply.

However. Easy to follow doesn’t mean easy to do. The clue is in the word ‘Bootcamp’! The first two weeks are strict, and the most restrictive. They’re also the weeks where you’re most likely to see pretty significant weight loss. After these first two weeks, you can move on to Bootcamp Light (if you wish).

Low carbing isn’t a very forgiving way of eating. It’s not like calorie counting, where you can compensate for one high calorie meal by having a very low one next time. You need to keep your carbs low at all meals, all day, for it to work optimally for you.

Bootcamp is, though, designed to be nutritionally positive. You will be eating plenty of fresh, unprocessed foods, along with lots of vegetables and salads.

As it’s a Bootcamp, you’ll find (and many of you will know (!) that I’m pretty strict. If you’re not following the rules, I will pick you up on that. Because I know that if you are cheating, then it won’t work for you. Which ultimately means you’ll be disappointed when it comes to weighing-in.

The ten rules

Here is a summary of the rules - the full explanation of these is on the spreadsheet

  1. (In the first two weeks) eat three proper meals a day
  2. Avoid processed foods
  3. Eat lots of fat
  4. Make sure you’re eating vegetables and salad with your meals
  5. Be careful about dairy (apart from butter, which is unlimited)
  6. You must drink a minimum of 2 litres of water per day
  7. (In the first two weeks) no alcohol
  8. (In the first two weeks) no fruit
  9. (In the first two weeks ) no nuts or seeds
  10. No sugar or artificial sweeteners

NB if you’re a vegetarian, you are allowed to include nuts and seeds, and some more processed foods like Quorn, tofu or soya-based products.

As well as following the rules, you need to know which foods you won't be eating during Bootcamp. These are:

  • pasta/noodles/rice (of any colour or type)
  • bread, in any form
  • pastry
  • sweet and savoury biscuits/crackers
  • cereals
  • sugar (which also includes honey, agave syrup and fruit sugar)
  • flour (and sauces/gravy thickened with flour)
  • cakes
  • full sugar fizzy drinks, and squash/cordial
  • fruit juice
  • potatoes, sweet potatoes, sweetcorn, beetroot
  • balsamic vinegar (all other vinegars are fine)
  • grains/pulses/legumes (which includes peas)
  • sweets
... and alcohol, of course!

For the first two weeks of Bootcamp, you must also exclude:

  • all fruit
  • nuts/seeds*
  • all chocolate
After the first two weeks of Bootcamp, if you wish, you can move to Bootcamp Light, which means you can add in:
  • some fruit - berries are the best
  • some nuts/seeds - in moderation, and choosing them carefully as the carb counts can vary dramatically
  • some chocolate - dark, high cocoa-content chocolate only

Foods you CAN eat and enjoy:

In the main, things you generally can't eat on any other diet! Low carb means high fat, so you will be able to enjoy things like:

  • butter
  • lard
  • cream
  • cheese
  • mayonnaise
  • olive oil
  • full fat yoghurt
  • No light/lite or low fat anything!
  • all meat/fish/seafood (although keep processed options to a minimum); fattier cuts/types of fish are encouraged
  • eggs (no restriction on how many per day/week)
  • oily dressings (especially using extra virgin olive oil/avocado oil)
  • lard/coconut oil (as well as butter) for frying food
  • LOTS of vegetables and salad

The very lovely @FinallyHere will be running the spreadsheet, where we record our progress each week - and which has loads of other information and resources for you. I'll post a link when we get going.

Very importantly:
THE DISCLAIMER
I, and any of the other MNetters who give advice here, are not medics and we are not qualified in nutrition or dietetics. Recommendations and support are based on our experiences and understanding of low carbing. Before starting, if you are on any kind of long-term medication (especially for hypertension, diabetes or high cholesterol), please check with your GP, as the results of low carbing can mean you may need to reduce your dosage. And if you’re pregnant or breast-feeding, we suggest you follow Bootcamp Light. If you have a history of disordered eating, please consider whether or not this is something that you should be doing.

I've been doing this for a long time, but it's always good to have the prep thread to remind me of how far I've strayed...

BIWI · 29/09/2026 13:55

Just a heads-up - I'm away from tomorrow until the weekend, so won't be posting much until then.

But as I've posted before, here's a link to the spreadsheet; have a read of the resources (on the tabs at the bottom) so you get a better feel for it. Also, a full version of the rules is on there, along with helpful carb counters.

There's also a FAQ thread which is worth a read

I think you mentioned on the sign-up thread, BIWI, that it would be good to make a statement of goals at the beginning of the bootcamp, for the purpose of loin-girding, realism and holding oneself to account.

So here is mine:

  1. I don't need to lose weight. I WANT to lose weight, but what I really need is to teach myself to focus on eating for health and energy, and to turn myself gently away from a disordered attitude to food.
  2. I will fall off the wagon. Learning to eat well is learning to jump back on the wagon cheerfully and fast, instead of sadly watching it rumble out of view.
  3. Portion control. PORTION CONTROL, WOMAN!
  4. Getting control of the evenings. Avoiding the habits that lead to snacking. E.g. sitting in the kitchen watching Netflix in easy reach of cupboards.

Thanks, @BIWI. Just placemarking for now.

KellyOnAHeli · 29/09/2026 17:57

Are red onions allowed in first two weeks please? I can’t see them on the spreadsheet so I’m wondering if they’re fine like shallots, or best avoided like brown onions.

BIWI · 29/09/2026 22:02

As far as I know, red onions have the same carb count as white/brown onions (but I'll check!)

Given that they form so much a part of so many dishes I tend not to worry too much about onions - but if you can use shallots instead that's always good! (Avoid the little round ones and go for the echalion/banana ones as they're much easier to peel)

I usually have almond milk in my tea/coffee. Is that ok or should i be aiming to have it black these two weeks?
I know the advise is veggies can have some nuts. Does it include nut milk?
I could prob stick to green tea/peppermint other herbal tea for two weeks tbf…. maybe

FinallyHere · 30/09/2026 20:36

Looking forward to your company lovely Bootcampers. I've been back on the waggon mid august and soo glad to be feeling the benefits of this way of eating.

Going to focus on matching portion size to my real hunger, reminding myself i can always go back and get more if i really am hungry after eating. Simples.

I don’t know about nut milks but if you’re looking for a hot drink that’s good without milk, have you tried rooibos tea? I really like it, it’s naturally caffeine free and it’s stocked in most supermarkets. The Tick Tock brand is quite often on special offer.

I have! It’s the only tea I drink, well that and Earl Grey. It’s lovely without milk too so will stick to having it without milk for the two weeks at least.
