Butter Not BreadSimple low carb for normal people

Low carb, explained like a mate would.

Simple food, plain English, and nothing you need a nutrition degree for. No weighing every crumb, no expensive powders, and no lard in your coffee.

What carbs actually are

All food is made of three main things: protein (meat, fish, eggs), fat (butter, oil, the fat on meat) and carbohydrates, or carbs.

Carbs are sugars and starches. Sugar is the obvious stuff: sweets, fizzy drinks, cakes, fruit juice. Starch is the stuff that doesn't taste sweet but is: bread, pasta, rice, potatoes, cereal. Starch is just lots of sugar stuck together, and your body unpicks it back into sugar very quickly. As far as your blood is concerned, a slice of toast isn't far off a couple of teaspoons of sugar.

Fibre is a carb too, but your body can't digest it, so it passes straight through. That's why UK food labels leave it out of the carbohydrate figure.

Here's the bit most people never get told: your body has to have protein and fat to stay alive. It doesn't have to have carbs. It can make the small amount of sugar it needs by itself.

What carbs do inside you

  1. You eat them, your blood sugar goes up. Bread, pasta and sugar get turned into sugar in your blood within minutes.
  2. Your body releases insulin. Too much sugar in the blood is harmful, so insulin's job is to get it out of the blood fast.
  3. A bit gets stored as fuel, the rest gets stored as fat. Your muscles and liver can only hold a small amount. Everything over that is turned into fat. While insulin is high, your body is in "store" mode, not "burn" mode.
  4. Your blood sugar drops, and you're hungry again. A couple of hours later you're tired, grumpy and looking for a biscuit. Round and round it goes.

Why carbs pile the weight on

It's not because you're greedy or weak. You put on weight when you eat more than your body uses, and carbs make that very easy to do:

  • They don't fill you upYou can eat a whole sharing bag of crisps and still want tea. Try doing that with three eggs.
  • The sugar crash makes you hungryThe up-and-down of blood sugar keeps you snacking all day.
  • Insulin tells your body to keep the fatWhile you're eating carbs all day, your body hardly gets the chance to burn what it's stored.
  • Carbs plus fat is made to be overeatenChips, pizza, biscuits, doughnuts. That mix hardly exists in nature, and food companies know nobody can stop at one.

Not every carb is the enemy. Green veg and berries are carbs too, and they're good for you. It's the bread, pasta, rice, potatoes and sugar that do the damage.

Why we eat far more than our grandparents did

  • Sugar was rationedIn Britain, sugar rationing didn't end until 1953. Sweets were a treat, not a daily thing.
  • Food was cooked, not bought ready-madeMeat and two veg, cooked at home. No meal deals, no ready meals, no takeaway apps.
  • No snacking all dayThree meals and maybe a biscuit with a cup of tea. Now there are crisps, chocolate and energy drinks at every till.
  • The low-fat mistakeFrom the 1980s we were told fat was the enemy. Food companies took the fat out and put sugar and starch in to make it taste of something.
  • Sugary drinks became normalFizzy pop, fruit juice and fancy coffees mean a lot of people drink a day's worth of sugar without eating anything.
  • Cereal and toast for breakfastStarting the day on carbs sets off the hunger cycle before 9am.
  • We move lessMore desk jobs, more driving, less walking and less physical work.

What it does to your health

  • Type 2 diabetesMore than 4 million people in the UK have been diagnosed with diabetes, and most of them have type 2. It's strongly linked to carrying extra weight, especially round the middle.
  • Being overweightAround 2 in 3 adults in England are now overweight or obese.
  • Heart disease and strokeExtra weight, high blood pressure and diabetes all raise the risk.
  • Fatty liverIt's not just drinkers. Too much sugar and extra weight can make fat build up in your liver.
  • TeethSugar is the main cause of tooth decay. Having teeth taken out is one of the most common reasons young children go into hospital in England.
  • Feeling rubbishEnergy crashes, cravings and always feeling hungry. Most people notice these change first.

This is general information, not medical advice. If you're worried about any of these, talk to your GP.

What low carb actually means

Carbs are the starchy and sugary foods: bread, pasta, rice, potatoes, cereal, cakes, biscuits, sweets and sugary drinks. Low carb just means eating a lot less of those, and filling up on meat, fish, eggs, cheese, veg and some fruit instead.

You don't have to go all-in. Pick the level that suits your life. You can always go lower later.

Start here

Steady

100–130g

carbs a day. Cut out the obvious stuff, keep a little fruit and the odd potato. Easy to keep going for years.

Most people

Lower

50–100g

carbs a day. Bread, pasta, rice and potatoes mostly gone. This is where a lot of people really feel the difference.

Optional

Strict (keto)

under 50g

carbs a day. Works for some people, but it's hard work and you don't need it to get results. Not where we start.

For comparison, a normal UK day is often 200g or more. Here's roughly what some everyday foods cost you (UK government food tables):

1 slice of white bread ≈17g Large jacket potato ≈55g Plate of pasta ≈85g Can of cola ≈36g Pint of bitter ≈12g Banana ≈20g 3-egg omelette under 1g

What's on the plate

Plenty

  • Meat, chicken, bacon, sausages (high meat %)
  • Fish and seafood
  • Eggs
  • Cheese, butter, cream, full-fat yoghurt
  • Green and leafy veg: broccoli, cauliflower, cabbage, spinach, courgette, green beans, salad
  • Olive oil

Some

  • Berries: raspberries, strawberries, blueberries
  • Nuts and seeds
  • Onions, peppers, tomatoes, carrots
  • 90% dark chocolate
  • Dry wine, spirits with diet mixers
  • Milk (it has more sugar than you'd think)

Not much

  • Bread, wraps, pasta, rice, noodles
  • Potatoes and chips
  • Cereal and porridge
  • Cakes, biscuits, sweets
  • Fizzy drinks, juice, smoothies
  • Beer, cider
  • Most "low fat" products (fat out, sugar in)

Why people do it

  • You're less hungryMeals with protein and fat keep you full for longer, so the 11am and 4pm snack attacks calm down.
  • Fewer cravingsAfter a couple of weeks, most people find sugar has a lot less pull on them.
  • Weight lossMany people lose weight without counting calories. Some of the first week's drop is water, so don't get carried away (or put off) by the scales early on.
  • Steadier energyFewer sugar highs and crashes through the day.
  • Blood sugarIt can help people with type 2 diabetes or prediabetes. If that's you, do it with your GP or nurse, not on your own.

The pitfalls nobody tells you about

  • Going too strict, too fastThe number one reason people fall off. They go full keto on Monday, feel rough by Wednesday, and are eating toast by Saturday. Start Steady.
  • The first-week wobbleHeadaches, tiredness or feeling a bit flat for a few days. Drink plenty of water and don't be shy with salt on your food. It passes.
  • Getting bunged upLess bread often means less fibre. Eat plenty of veg, drink water, and add a few nuts or berries.
  • Hidden carbsSauces, marinades, cheap sausages, "healthy" cereal bars and flavoured yoghurts can be loaded. See the Shopping page.
  • "Keto" junkBars, shakes and biscuits sold as keto are often expensive and still junk. Real food is cheaper and works better.
  • Eating out and travelThe bit that catches most people. It's easier than you think once you know what to ask for. See Eating out.
  • Forgetting vegLow carb is not "only meat". Fill half the plate with veg.
Check with your GP first if…

you take medication for diabetes or blood pressure (doses may need changing as your diet changes), you're pregnant or breastfeeding, you have kidney problems, or you've had an eating disorder. This site is everyday food and common sense, not medical advice.

Tried it before and fallen off?

Join the club. Most people who've "failed" at low carb were sold the extreme version: fat bombs, strict macros, butter in coffee, and a feeling you'd ruined everything with one chip.

It's not all or nothing. A low-carb week with one pizza in it is still a good week.

Start at Steady, change one meal at a time (breakfast is usually the easiest), and only go lower if you want to.

Your first week

  1. Pick your level. Steady is fine. Seriously.
  2. Sort breakfast first. Eggs any way, bacon, full-fat Greek yoghurt with berries. Try the first omelette.
  3. Do one shop. Use the My kitchen list so the cupboards are full of things you can eat.
  4. Swap the sides, not the meal. Same chicken, same steak, but veg or salad instead of chips, rice or pasta.
  5. Have a sweet option ready. Berries and cream, or a box of peanut butter cups in the freezer, stops a craving turning into a biscuit binge.
  6. Drink water, salt your food. This sorts out most first-week wobbles.
  7. Plan one meal out. Read Eating out before you need it, not in the queue.
