What should you eat on a low-carb diet?

According to Dr John Briffa, in his book Escape the Diet Trap, adults need around 100g of carbohydrate a day. However, most of us have little idea how much carbohydrate is in the food we eat.

You can get a clearer picture by analysing three meals consumed during a 'typical' day.

Without counting milk (in tea and coffee), or any snacks you might consume, the meals eaten during this typical day add up to 172g carbohydrates - almost twice as much as you need for your daily energy requirements. The surplus will be stored by your body as fat.

The emphasis in your low-carb diet should be on eating natural and unprocessed foods. Cooking from scratch is always better, because in that way you can control the amount of carbohydrate you are consuming.

How many carbs do you eat in an average day?


1 slice Hovis (medium) wholemeal toast with butter/margarine
1 serving of Special K (30g + 125ml semi-skimmed milk)
1 x 250ml glass of orange juice

Sandwich, made with two slices of wholemeal bread, with butter/margarine, and ham/tuna/cheese
1 packet Walkers Cheese & Onion crisps
1 x 2 finger Kit Kat

Spaghetti Bolognese, made with 50g Sainsbury's spaghetti (a small portion) and a serving of Dolmio Original Bolognese Sauce

This equates to 172g of carbohydrate - almost double your daily energy requirement.

Processed and pre-prepared foods often contain surprisingly high amounts of carbohydrate, often because they add sugars, or use starches to thicken sauces.

The type and amount of foods you can eat will depend on how strict your low-carb diet is, and what stage of the diet you have reached.

As you lose weight and reach your target, you will be able to start including higher amounts of carbohydrate.

What to eat on a low-carb diet

  • Meat and fish (as long as they aren't processed) and eggs can be eaten in any quantity
  • Most vegetables and salads - potatoes are a definite exception here
  • Butter - any amount - for frying and adding to cooked vegetables
  • Oil - for frying and for use in salad dressings
  • Up to 100g of cheese a day
  • Cream (in moderate quantities) and full-fat yoghurt
Foods to avoid on a low-carb diet (particularly in the early, strict phase)

  • Bread/crackers
  • Rice
  • Pasta
  • Other grains
  • Nuts/seeds
  • Potatoes
  • Fruit
  • Sugar/honey/syrup/maple syrup
  • Legumes, eg lentils, chickpeas, kidney beans
  • Flour/cornflour
  • Biscuits/chocolate/sweets
  • Alcohol

As you reach your target weight, and start to look to maintain it, you can gradually include some of the foods in this list again - in moderation.

The idea is that you very gradually add more carbs to your diet until you start to gain weight. By doing it gradually, you learn which foods you can tolerate, as well as the quantities of carbs you can eat without gaining weight.

All these recipes demonstrate how easy it is to follow a low-carb diet and, importantly, how easy it is to cook lovely, tasty food that all the family can enjoy. You won't feel like you're on a diet at all - not one iota of deprivation will be required to lose weight if you eat this way. Honest. 

  • Hopefully, you will stay there. But if you see reaching your target as the green light to re-introduce all the carbs you were eating before, then the weight will just pile back on.

    Although you should be able to eat more carbs, and may be able to eat bread, potatoes, rice and/or pasta occasionally, these are still the carbs that have to be eaten in moderation, because of their impact on your blood sugar levels.

    Dr Atkins has a pre-maintenance phase in his diet, where he recommends that you aim for very, very slow weight loss as you reach your target weight - less than a pound a week, for a period of up to three months. This is achieved by gradually increasing the carbs in your diet, again. The thinking is that this will help you adjust to a level of carbohydrates and a style of eating you can adopt for the rest of your life.

    Once you reach your target weight, you need to remain vigilant about what you are eating, and recognise that you are in control of your food - not the other way round.

    You will be able to indulge in higher carb meals, and treats, but need to be very careful that these don't trigger carb cravings again.

    To help keep you on the 'straight and narrow', Dr Atkins suggests you weigh yourself once a week, and have a 5lb maximum gain over your target weight. If your weight goes back up, then it's time to cut the carbs you're eating until you have returned to your acceptable weight range. 

    If your child is overweight, you could consider reducing their carbohydrate intake, but discuss it with their GP first.
