Low-carb Bootcamps - ongoing chat thread for EVERYONE

173 replies

venusandmars · 29/06/2025 08:46

A new thread to gather together those who have been on the most recent short bootcamp, those who were on the previous one, and all those who have followed bootcamp over the years.

It's ongoing chat so there's no spreadsheet. But effective low-carb principles remain the same, and I've copied the rules again at the end of this post. Of course, in ongoing chat most people will be following their own version of boot-camp, not the strict rules. So there may be some fruit (berries, rhubarb etc), some nuts, the odd glass of alcohol. Some may be mixing low-carb with intermittent fasting.

My own ongoing approach is to add in a few healthy carbs (lentils, beetroot, beans) up to one a week - certainly no more often. I think over the long term my body responds well to the change occasionally and I do miss pulses and some veg.

In ingoing chat our goals will vary. Some will be continuing with a stricter approach with a sfecific event approaching or a weight goal in mind; some will be looking for an ongoing and sustainable gentle weight loss; some will be fine with where they are and following this way of eating to avoid the yo-yo of weight gain; and everyone will be appreciating the general support, the reminder to drink all the water, and the fantastic and inspiring recipies and menu ideas.

Whatever you are aiming for, welcome and good luck!

BOOTCAMP RULES
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!)"
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. 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 is from
www.low-carbdiet.co.uk/:
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.
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.
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.

@Alwayslearning25 and welcome to bootcamp. I’d encourage you to read some of the older threads. You will find many of the threads with week one in the title will set out the ‘rules’ of bootcamp.

Many also contain a link to a spreadsheet which includes a lot of resources. I’m on my phone at the moment or I would post the link here. You will find answers to your questions there set out much more clearly than I can explain without out looking up the spreadsheet.

Hope you join us bootcsmpers, the more the merrier

BIWI · 27/12/2025 14:06

If you’re thinking of doing Bootcamp @Alwayslearning25 then that’s way too many carbs, I’m afraid.

General rule of thumb is 70-75% fat 20-25% protein and only 5-10% carbs. The carbs should come in the form of veg (not including potatoes, sweet potatoes, sweetcorn or beetroot) and salad. No fruit in the first two weeks.

After the first two weeks of Bootcamp you can up the carbs slightly, by including some fruit (mainly berries) and slightly carbier veg as well as (some) nuts and seeds.

Bootcamp lasts for 8 weeks - so 2 very strict weeks and then 6 slightly less strict - but strict nevertheless. It’s not called Bootcamp for nothing!

Alwayslearning25 · 27/12/2025 14:23

Sorry to clarify, I wasn't meaning my overall diet, but sometimes to add to a stew. So the 32% was mostly perl barley and lentils. Or any item of food to add to a meal.

Alwayslearning25 · 27/12/2025 14:33

Thank you @FinallyHere and @BIWI . Over the past two years I've gone from slightly high in the normal BMI range, to overweight nearly into obese. My diet is carb heavy. So I'm ready to do this bootcamp, I'll go away and do some homework ready for January.

venusandmars · 27/12/2025 14:59

@Alwayslearning25 I have loved Rangjang Chatterjee since reading his 4 pillars book (although I think it needs a 5th pillar which is 'community') Hopefully on the next bootcamp you will find that community!

Sometimes people post what they are eating for the day, which can really help with planning your own meals, and give you fantastic ideas for lovely recipes.

Is your stew mix something you add to a load of meat and gravy? That is fantastic and healthy, but when I do bootcamp I avoid anything like that. When I'm between bootcamps and trying to maintain, I might have something like that once a week.

See you on the new bootcamp thread!

OP posts:
Alwayslearning25 · 27/12/2025 15:12

Something like that. It needs soaking overnight and cooking for 50 minutes so I used it with turkey broth today.

ARoomSomewhere · 27/12/2025 15:56

Please can I be added ? (No Spreadsheet)
Thank you x

@ARoomSomewhere I’ve added you to the list (on the sign-up thread)

venusandmars · 29/12/2025 15:35

Going out for lunch with family later this week and I suggested a place where I know I can make good food choices. Turns out there will be some children also attending so an alternative has been proposed, a sort of indoor street food place so all the kids can have their tastes accommodated. Of course I agreed.

I have just looked at the menus and there's not one sodding thing that I want. It's all pasta, pizza, loaded fries, noodles, rice, bao buns. Lots of things are fried in batter or covered a sweet sticky sauce. Not a vegetable in sight and barely a scrap of salad. So I coud have the chiken tikka, but there's nothing to go with it that isn't carb. I really hate to look like I'm obviously leaving the carbs - a couple of people will comment negatively. Ah well, I'll just have to do my best to eat around things - and maybe have a good breakfast before I go so I'm not too hungry before I start. Thank goodness it's this week, rather than week 1 of the new bootcamp Grin or @BIWI would have her big stick out early.

OP posts:
BIWI · 29/12/2025 15:50

I hate it when that happens - places like Frankie & Benny’s, or Bill’s are good examples. Sugar in everything, it seems!

Alwayslearning25 · 30/12/2025 06:03

Good evening. I've had a read of different threads @BIWI has suggested. And searched some keto recipes, as this does seem very similar to keto/Atkins (correct me if I'm wrong here). I would like to do this because:
1, I'm curious how it will make me feel.
2, I've gone from 68kg to 75 the past two years and up to a size 16-18 first time in my life.
3 I don't normally do New years resolutions, but I haven't been disciplined this year with food so feel like a drastic measure is nessersary.
4, challenge is fun

Drawbacks
1, I've heard on Zoe that long term low carbs is not good for gut flora as it doesn't have much fibre...I guess that's why you introduce some after 2 weeks?
2, It's extreme so could give me a less healthy, obsessive relationship with food. I've recently come to the conclusion I'm probably ADHD after a couple of comments and doing a screening test.
3, I've been changing my diet past couple of days, and I felt slightly sick.

Also, in week three is peanut butter on Apple slices a good snack/ meal addition?

venusandmars · 30/12/2025 09:13

Hi @Alwayslearning25 good on you for doing some research and for thinking through how / whether this approach woud work for you.

BIWI's bootcamp is different from Atkins. Atkins starts with very low carbs and high protein (although that balance changes over the phases). On Bootcamp there is huge encouragement to eat a FLGV (f'k load of green vegetable) - cauliflower, green beans, cabbage, broccoli, spinach, avocado, asparagus, aubergine, tomatoes, radishes, courgette, mushroom, peppers, cucumber etc. All of these have lots of fibre and are low carb. Lots of the menus that people post, or the recipe ideas include a variety of veg.

I am also of the opinion that you can do good keto (where you're eating good ingredients, not much processed stuff or processed meat, and maintaining a healthy diet) or keto which is based on bacon, eggs, cheese, fatty cuts of meat. Often on strict keto approaches people are chasing ketogenesis and are adjusting their diet to achieve that, sometimes with high fat snacks containing artificial sugar. On bootcamp we don't even measure ketones, that's not the aim (and if you're drinking enough water then ketones won't show up strongly in your urine anyway). Instead the aim is to develop a healthy sustainable way of eating.

I also like that on this bootcamp I'm not having to weigh foods or calorie count - all of that for too many years was not good for my relationship with food.

I've been following this approach for several years (and with the exception of lockdown when all my good habits went out the window) I have maintained a healthy weight. I find that on my own some unhealthy eating creeps back in - too many crisps, a fondness for toast, too much wine Blush and it always helps me to be part of the group to reset my habits, to feel encouraged, and to discover some faulous new recipes. Once the 8 week bootcamp is over, I eat mainly following the rules, but once a week or so, I have beans or pulses.

If you've cut out carbs drastically in the last couple of days then it could be 'carb flu'. Other posters recommend electrolytes (I don't know which brands) to help in the early phase, or maybe half a slice of toast to see if that improves things.

Only you can decide whether this is the right approach for you, but when bootcamp starts next week and there are lots of posts (the thread tends to move very quickly at the start), you will get a better idea of what people are eating for their meals, and snacks (if they need them).

BIWI · 30/12/2025 10:13

@Alwayslearning25

Have you had a read of the resources on the spreadsheet?

The OP of this thread is also worth a read (and also contains a link to the spreadsheet in case you haven’t found it!), for further background info.

@venusandmars’ reply is really good, and hopefully that helps. I’ll add my two pennyworth as well!

You asked:

I'm curious how it will make me feel

Obviously everyone is different, but in general people report that they have more energy and that, as well as weight loss, various other conditions either improve or disappear altogether. For me, for example, my IBS is controlled by following a low carb diet. I had no idea this would be the case when I first started low carbing, around 20 years ago, but it’s a very, very welcome benefit. Women with PCOS find it helps them - and in several cases we’ve seen such women conceive, which is a massive positive for this WOE. Better skin, better sleep, less joint pain - to add just a few more. The only way you’ll know, of course, is by trying!

Be aware, however, that in the first week you may not feel great. This is called carb flu - if you read the FAQ thread you’ll see I’ve dealt with that there. It’s a temporary thing but if you’re really suffering, then an electrolyte supplement will help. Specifically you’re looking to increase sodium, potassium and magnesium in your diet.

Drawbacks
1, I've heard on Zoe that long term low carbs is not good for gut flora as it doesn't have much fibre...I guess that's why you introduce some after 2 weeks?

It’s impossible to criticise all low carb diets for this, as they vary so widely. But on Bootcamp one of the key rules (rule no 4) is that your carbs MUST come from vegetables and salad. This is to ensure good nutrition, and you should get plenty of fibre this way. Bootcamp is NOT a no carb diet. We still eat carbs, just in the form of veg/salad - and after the first two weeks, some fruit.

2, It's extreme so could give me a less healthy, obsessive relationship with food. I've recently come to the conclusion I'm probably ADHD after a couple of comments and doing a screening test.

It’s only the first two weeks of Bootcamp that are especially extreme. After that it is a bit more relaxed - but only for a further 6 weeks. Unless you already have a dysfunctional relationship with food (in which case you will be discouraged from following Bootcamp anyway), this shouldn’t result in an unhealthy relationship with food. In many cases, people realise that their relationship with food becomes more healthy - as there’s a focus on eating freshly prepared/unprocessed foods, and cooking from scratch, with plenty of vegetables and salads.

3, I've been changing my diet past couple of days, and I felt slightly sick

Don’t know what you’ve changed/what you’re doing, but if you’ve really cut down on the carbs then this could be carb flu - see the FAQ thread for more info.

Also, in week three is peanut butter on Apple slices a good snack/ meal addition?

Not really. Peanut butter depends - carb counts vary widely from brand to brand. Some are OK. However, apples are a more carby fruit and not one we’d recommend during Bootcamp. If you look at the fruit carb count on the spreadsheet (just check out the tabs at the bottom) you’ll see that they’re in the red zone - i.e. ones we advise people to avoid.

When you’re into the swing of Bootcamp, which should definitely be the case by week 3, you should find that you’re not hungry between meals, and therefore won’t be looking to snack. However, our mantra is also, always, ‘if you’re hungry, then eat!’ so there may be times when you need to snack. In that case, something like celery or cucumber with pâté or (full fat) cream cheese would be a better choice.

Hope this helps, but keep posting any questions or concerns you may have and we’ll try to help Flowers

@BIWI I'm planning and prepping for next week... Question about chia: can we have them from the start? Do they count as seeds/nuts and only OK after the first 2 weeks? Or are they not allowed at all?

I've been having them mixed with ffgy and water (with a few frozen berries and some nuts and seeds - which I know I can't have until week 3).

OP posts:
BIWI · 31/12/2025 15:07

I think we’ve allowed them in previous Bootcamps, given that they are very low in carbs (2.4g per 100g according to Tesco’s website)

DryWhiteagainW · 01/01/2026 16:26

CAn I join you please? Did this a couple of years ago with you and it was really good. Weight has crept back on, I need accountability.

DryWhiteagainW · 02/01/2026 19:42

Not starting until Monday properly but I made a nice dinner just now (adding left over spuds for DH)

steam handful of green beans (half packet) and 6 ish stems of tender stem brocolli .

In high sided frying pan , sauté :
in olive oil 4 shallots
2 cloves of garlic
approx 1tbsp hot paprika
salt and pepper
a chopped red pepper
a sliced courgette
6 cherry tomatoes
2 chicken breast chopped

when it’s all cooked chuck in the tenderstem and green beans.

was delicious and v pretty.

next time I might add a spoon of Philadelphia to make the sauce creamy.

Think this sticks to the no carb rules?

BIWI · 02/01/2026 21:11

It does @DryWhiteagainW! Just remember, though, that we’re high fat - so chicken thighs would be better than breasts - and Philadelphia would be a great addition. Sounds lovely Flowers
Well done you for getting on the wagon early Grin

DryWhiteagainW · 03/01/2026 16:42

Are olives allowed? They’re not in the list and I’ve always wondered.
love chicken thighs so I’ll use them next time

BIWI · 03/01/2026 18:18

Olives are perfect!

DryWhiteagainW · 03/01/2026 19:41
