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.

Just a question. I read that even when on a low-carb diet you have to watch your calories or it won't work. So it you eat a lot of full fat stuff you will still put on weight or not lose weight?

Have you read the FAQ thread @WeAreNumpties?

5. Do we need to count calories as well?
Yes and no!

At the outset of Bootcamp you don’t need to count calories at all. Bootcamp was designed to be easy to follow – mainly because I can’t bear having to weigh and count everything all the time! It also encourages what I think to be an unhealthy obsession with food, rather than creating a mindset that’s about enjoying our food.

As long as you’re keeping your carbs low, you will lose weight. In fact, there’s a distinct calorie advantage when you’re low carbing. A calorie of carbohydrate will have much more impact on your insulin levels (therefore your weight) than a calorie of protein or fat.

That said, this isn’t an excuse to go mad and overload your plate. You still need to be mindful of your portions, and to only eat when you’re hungry. You may find that at a specific mealtime that you’re not hungry – this is a very welcome benefit of low carbing, that it acts as a natural appetite suppressant. If you’re not hungry, don’t force yourself to eat!

However, as you near your target weight, you will find that weight loss slows down. And one of the things to take into account at that point is your calorie intake. It also appears to be true, sadly, that as we age, we need fewer calories anyway – so it’s always worth considering how much you’re eating, and whether or not you need to eat that much.

As an example, if you were going to cook yourself bacon and eggs for breakfast (and who wouldn’t want to?!), that you probably serve yourself two slices of bacon and two fried eggs. That seems like a natural-sized portion. But is it? How about two slices of bacon and one egg? Or two eggs and one slice of bacon?

I read that even when on a low-carb diet you have to watch your calories or it won't work

Where did you read this?

@BIWI thank you for your very helpful reply. I'm not being funny, it was a genuine question as I am thinking of doing the bootcamp myself - I did a keto diet a few years ago. I hadn't read the Q & A thread, there a quite a few long threads about bootcamp so I was a bit overwhelmed. I've read quite a lot of articles - sorry, I can't remember where now and I'm full of cold so can't be bothered googling - which said that it used to be thought you could eat what you wanted within the keto guidelines but now it's thought that you still have to be mindful of the amount you ate. I went on keto because I had to take replacement steroids which made me hungry all the time and I found it helped me control the hunger but after a while I stopped losing weight so I stopped. I no longer have to take steroids but I'd like to lose a stone.
