General FAQs

Well it’s simple… it’s us!

The Cambridge Diet was our original brand name way back when we first launched in 1984. You might also know us as Cambridge Weight Plan. Fast forward to last year, we rebranded to The 1:1 Diet by Cambridge Weight Plan. Whilst we’ve moved on from this name, we know people still search for, and refer to us as, The Cambridge Diet.

We are different from where we were in the 80’s, but only because we’ve come on leaps and bounds, with a huge, ever-evolving product range and a fantastic new brand. We still have our flexible Steps, and super-supportive Consultants ready to help you hit those weight-loss goals, big or small!

Wanna know more? Just check out How it works, our blog for super tasty recipes, product hacks and dieter stories, plus our other FAQs to give you the low-down on all things on The 1:1 Diet.
The 1:1 Diet is a lot more flexible than other weight-loss plans and it’s the ONLY one that gives you dedicated, one-to-one support from your own personal diet Consultant. That means your diet is designed for you, and only you. Together with your Consultant, you’ll work out an easy-to-follow eating plan that fits with your routine and gets you the results you want.
It’s really important to keep hydrated while you’re on The 1:1 Diet. We recommend that you drink at least 2.25 litres or four pints of water every day. Drinking lots helps to maintain your blood volume and prevents dehydration. Little and often is the way to go - try to keep drinking throughout the day. It’s a lot easier that trying to drink 4 pints all at once.

Drinking water is essential for a healthy body, whether you’re on a diet or not. If you’re on Meal Replacement Products and a balanced meal, it’s really, really important. The 1:1 Diet products give you balanced nutrition but in a very concentrated form. If you’re having Ready to Drink shakes, you should drink 250ml or half a pint of water with each one. Drinking lots of water will compensate for the fluid that you normally take in through food. Without it, you could become dehydrated, and that leads to headaches, dizziness, tiredness, irritability and constipation. Ugh. Pass the water.

Not if you are replacing all of your meals with The 1:1 Diet products, no. You can use our water flavourings, or have herbal and fruit teas. If you really want normal tea and coffee but can’t stand drinking them black, try whitening them with a little bit of our Vanilla Shake. Vanilla latté anyone?
No. The only thing that beats alcohol’s calorie density (7kcal per gram) is fat (9kcal per gram). An average unit of alcohol has 85 calories, and alcohol has no significant nutritional value. It can also have the effect of making you very hungry, not to mention lowering your will power – really what you need when you’re focussed on weight loss.
Yes you will. The first day or two are usually the hardest - you may well feel tired and grumpy too. Once your body has adjusted to its new calorie intake, it will get much easier. And once you start seeing and feeling that weight disappearing, you’ll start feeling much more motivated. Stick with it.
Until recently, it was believed that gum might increase cravings because it stimulates the gastric juices, which might trigger the body’s hunger response, so we recommended dieters avoid gum on plan but if you wanted a quick, three-minute chew, it was ok if you really felt the urge.

However, in the last few years, it has emerged that chewing gum may actually have a very small positive effect on energy expenditure and reducing hunger, so while this research isn’t definitive and the effect is probably very small (if there is one), we’re now giving calorie-free gum the green light. However, everyone is different, so if you find it increases your cravings, take it off the menu!
One of the huge benefits of The 1:1 Diet is that all your food is nutritionally balanced. Every single product contains a third of your recommended daily allowance of vitamins, minerals and trace elements, so when you have three a day, you get all the nutrients you need.
Reducing your food and calorie intake will help you lose weight, but you have to make increasingly careful food choices as you decrease your calories, so as to get enough nutrients. Unless you’re an expert in nutrition or do a lot of research, it is unlikely that you would be able to get all the nutrition you need from less than 1000 kcal of ordinary food every day. With The 1:1 Diet products and Plan have been shown in a wide range of research to be safe and effective. Plus, you don't get the amazing one-to-one support from solo calorie counting!
There’s no upper limit to the age of a dieter. We advise all customers to consult their GP before starting any weight loss programme.
All teenagers should be encouraged to eat sensibly and exercise regularly to maintain a healthy weight. The 1:1 Diet is not suitable for children under 15, and only available for children over 15 with the approval of their GP and support of a parent or guardian who must attend all consultations. For dieters between 15 and under 18, a structured diet of 1000kcal, 1200kcal or 1500 kcal/day will usually be recommended. Only in very rare circumstances, a 810 kcal/day diet may be recommended with GP approval.

Yes. It’s a good idea to start reducing your food intake, particularly carbohydrates, the week before you start dieting. This will help prevent carbohydrate withdrawal headaches, which can speed up the onset of ketosis, which may reduce cravings. You should also increase the amount of water you drink to 1.7 litres (or three pints) a day. If you have ever been constipated, taking some natural fibre might help – constipation is a common side effect with Meal Replacement Products. Check with your GP if necessary.

On The 1:1 Diet, you’ll think long term, right from the start. Our aim is not just to help you lose weight, but to keep it off for good. For successful long-term weight management, you’ll need to make long-term and permanent changes to your lifestyle and diet. Your Consultant will help you to understand these changes early on, and support you in building a whole new relationship with food.
When you reach your desired weight, you need to maintain the good habits that have got you there. Go back to bad eating habits, and the weight you’ve lost will inevitably pile back on. Your Consultant will help you find a diet and routine to keep your weight stable.

If you are starting The 1:1 Diet on Step 2, you should only do some gentle walking for the first couple of weeks. This will allow your body to adjust to its new calorie intake. After that, you can start building more exercise into your day. How much exercise you take depends on a number of factors: your diet, any medical conditions or medication, fitness, age, lifestyle and level of current activity. Physical activity is an important part of every weight loss journey, and key to long-term weight management. If you want to do rigorous exercise at the gym or you are in training for a sports event, you need to be on a diet of 1000kcal or more.

In general, yes, it’s fine to drink coffee. Coffee may have an influence on your blood sugar but it won’t prevent you losing weight. In fact, some research even suggests that it may have some beneficial effects on the liver and your metabolism. However, obviously drinking coffee with milk and/or sugar increases calorie intake and so if you intend to add milk or sugar, this should be discussed with your Consultant.
If any of the following descriptions sound like you, you will NOT be able to follow The 1:1 Diet: -Your BMI is below 20 -You are under 15 years of age -You have had a heart attack or stroke in the past 3 months -You are taking prescribed monoamine oxidase inhibitor medication -You are taking anti-obesity medication -You are a substance misuser or dependent on alcohol -You are pregnant or breastfeeding, or have given birth in the past 3 months For anyone else, a Consultant is best placed to tell you if the diet is suitable.

The 1:1 Diet works by balancing replacement products – shakes, soups, ready meals, bars and snacks - with normal everyday food. You can start on Step 2, which consists of three meal replacement products and a balanced meal – it makes life a lot easier because you don’t have to go food shopping nearly as much as you used to, face temptation OR count calories. Then gradually, your meal replacement products are swapped for everyday food so you can get back to normal and keep the weight off.

When the original Cambridge Weight Plan was developed, a vast amount of research went into ensuring that the diet provided the right amount of protein and carbohydrate to minimise the loss of lean body tissue.

If you have symptoms relating to heartburn or gastric acid and want to do Step 2, it may be helpful to take your products in half portions instead of the three full ones. The good news is that you can follow any Step.

Lactose intolerance is the inability to digest lactose (milk sugar) and is caused by a deficiency of lactase, an enzyme released by the small intestine that allows milk sugar to be absorbed into the bloodstream. Luckily for you, we have a range of lactose-free products available so you’d still be able to use The 1:1 Diet.
Arthritis is a degenerative disease affecting joints. Weight loss is regarded very important in the treatment of arthritis. A lighter body puts less strain on the joints and some dieters find they may need less of their medication.

Don’t worry, it’s only The 1:1 Diet Peanut Crispy Bar that actually contains peanuts. Please note though that all other products in the The 1:1 Diet range are not made in a nut-free environment and therefore may contain nuts due to the possibility of cross contamination. The only exceptions to this are the The 1:1 Diet Ready to Drink Shakes. Please see the Allergies/Intolerances/Choices section for further information.

This is almost certainly due to a reduced thermogenic response to a reduced food intake. Large meals cause the body to generate a lot of body heat, while smaller meals produce less heat. Individuals differ widely in their thermogenic response. Your hands and feet may feel particularly cold, brrr... but this is a completely normal response. Your body is just trying to conserve heat and energy due to the reduced calorie intake. Other factors that influence body heat production include the slight reduction in metabolic rate, which always happens during weight loss and, of course, the loss of insulating fat! Don’t worry though, if you are sensitive to the cold try moving around a little more and be sure to wrap up warmly – many light layers are more effective than a single heavy layer.

Less frequent bowel movements may occur because The 1:1 Diet products are not as bulky as normal food. But to tackle this, keep well hydrated and drink at least 2.25 litres/ 4 pints of fluid daily in addition to the water used to mix your products. If you have previously suffered with constipation, let your Consultant know before you start. We’ve got you covered, The 1:1 Diet Fibre can be added to your shakes from day one and this may help avoid constipation. Less frequent bowel movements may occur because The 1:1 Diet products are not as bulky as normal food. To combat this, keep well hydrated and drink at least 2.25 litres/ 4 pints of fluid daily in addition to the water used to mix your products. If you have previously suffered with constipation, let your Consultant know before you start. Adding Cambridge Fibre to your shakes from day one may help avoid constipation.

You may get some leg cramps in the initial stages of Step 1, they are caused by the increased movement of fluid in the body’s tissues as water shifts and your sodium levels change. If you are still struggling please consult your GP or pharmacist. Don’t forget your Consultant will be able to advise you further on this.
We are sorry to hear this, but don’t worry, this is usually a minor problem and should last for only a short time. Some people are not used to the mineral content in The 1:1 Diet Products. Therefore it is a good idea to drink an extra glass of water at the same time as having a The 1:1 Diet Products. Here’s some advice from us: Take The 1:1 Diet products in the form of half portions (6/8 half portions per day, rather than 3/4 full portions) initially to dilute the mineral intake. Another possible cause of continued diarrhoea is lactose intolerance. Some people cannot digest the lactose in milk products and diarrhoea can occur. To ensure you don’t have to miss out, we have a range of lactose-free products that could be used instead. If you have diarrhoea, which has lasted longer than the first few days of the Plan, you should seek medical advice from your GP.
Hair loss can be linked with weight loss. The thinning of hair and hair loss can occur during and sometimes after the weight loss phase. But weight loss is not the only reason for hair thinning and we would therefore recommend you seek medical advice from your GP if you are concerned.
Hormone levels fluctuate when there are changes in weight – particularly in women. Rapid weight loss may temporarily affect the menstrual cycle. Ovulation, however, is probably not interrupted. To go into detail, in most cases the menstrual cycle remains unchanged but for some women breakthrough bleeding or heavier periods may occur. Others may find that their periods stop for a while. Fertility may also be affected and unexpected pregnancies have been known to occur, therefore if you have been trying unsuccessfully to become pregnant, you need to be aware that during and after weight loss, fertility may increase. The metabolism of hormonal contraceptives may be affected during effective weight loss and so we recommend additional methods of contraception if you do not wish to fall pregnant while on a programme.
Some people are more sensitive to the high concentration of minerals and vitamins in the products, and therefore my feel a little queasy, but that’s nothing that a glass full of H20 can’t fix. Another option would be to have your The 1:1 Diet products as 6/8 half portions per day, rather than 3/4 full portions, as this would help to split the mineral content you have each time.
Skin rashes can be caused by any number of things. However, just occasionally, there may be something in the formula of The 1:1 Diet products to which someone has an allergic reaction to. If a rash occurs while using The 1:1 Diet you should stop the Plan straight away. If the rash fails to settle or progresses, then seek medical advice. When the rash has gone down, if you wish to restart The 1:1 Diet then seek advice from your Consultant on how to do this. Why not also take some time to look at the Allergies/Intolerances/Choices chart on the website. Food allergies should be properly investigated and allergen-free diets should be based on sound scientific tests.
