Your fat burning questions answered
How’s this different to other diet plans?
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.
How much water do I need to drink?
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.
Why do I have to drink so much water?
Drinking water is essential for a healthy body, whether you’re on a diet or not. If you’re on Total Diet Replacements and The 1:1 Diet is your only source of nutrition, 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.
Can I drink low calorie squashes instead of black tea and coffee?
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 flavour sachets. Vanilla latté anyone?
Is alcohol allowed while following The 1:1 Diet?
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 and weakening your resolve – really not a good idea when you’re focussed on weight loss.
Is it OK to drink coffee when I’m on Total Diet Replacement?
It’s generally not good for you to drink large quantities of coffee or cola. Coffee can change how you digest carbohydrates and cola drinks may trigger hunger in some people. Herbal and fruit teas are a good alternative and give you loads of different flavours to try.
Will I feel hungry on The 1:1 Diet?
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.
Can I chew calorie-free gum on The 1:1 Diet?
When you’re replacing all your meals with The 1:1 Diet food, it is best to avoid all chewing gum, even calorie free. Chewing gum stimulates the release of gastric juices and makes you feel hungry. If you really need to, chew for two or three minutes and then put it in the bin.
Will I need vitamin supplements when I’m on The 1:1 Diet?
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.
Can I achieve the same results as The 1:1 Diet by limiting my calories?
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.
Do I have to eat all 3 meals when I’m on Total Diet Replacement?
Yes. Our products provide all your essential daily nutrients to keep your body well nourished. It is very important that you take all of your meals.
What age should a person stop eating The 1:1 Diet products?
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.
Can a 16 year old go on The 1:1 Diet?
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 14, and only available for children over 14 with the approval of their GP and support of a parent or guardian who must attend all consultations. For dieters between 14 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.
Do I need to prepare before starting The 1:1 Diet?
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 ever been constipated, taking some natural fibre might help – constipation is a common side effect with a Total Diet Replacement diet. Check with your GP if necessary.
When do I need to think about my long term weight management?
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.
How do I manage my new weight when I reach my target?
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.
Do you recommend exercise with The 1:1 Diet?
If you are starting The 1:1 Diet with Total Diet Replacement, 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.
I am a Muslim. How can I continue on Total Diet Replacement during Ramadan?
During Ramadan, strict fasting is observed during daylight hours, so all your diet food and drink needs to be taken before dawn and after sunset. Try to spread your meals out as evenly as possible - you might need to go to bed later and get up a bit earlier. Alternatively, you might want to wait and start your diet on the day of Eid ul-Fitr.

What will I eat?
The 1:1 Diet works by balancing replacement products – shakes, soups, ready meals, bars and snacks - with normal everyday food. You can start with Total Diet Replacement, or nearly all meal replacement products – it makes life a lot easier because you don’t have to go food shopping, face temptation OR count calories. Then gradually, your meal replacement products are swapped for normal everyday food so you can get back to normal and keep the weight off.
Do The 1:1 Diet products contain enough protein to be the sole source of nutrition?
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.

Why are pregnant or breastfeeding women advised not to use The 1:1 Diet?
Any woman who is pregnant, breastfeeding or who has given birth in the last three months cannot use The 1:1 Diet.

In pregnancy, care has to be taken not to exceed intakes of some micro-nutrients. Current guidelines advise against taking extra vitamin A, which is present in all of our products.

Why do I feel cold on The 1:1 Diet Step 1 programme?
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.
Is it normal to get constipated after starting The 1:1 Diet?
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.

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.

I have been on The 1:1 Diet for two weeks and am getting cramp in my legs. Is the diet causing this?
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.
Just after starting The 1:1 Diet I suffered from diarrhoea. Why is 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.
I have lost 19kg (3st) on the Step 1 and am now experiencing some hair loss. Is this due to the The 1:1 Diet?
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.
Why do I get a headache on Step 1?
Got a sore head? You may be experiencing carbohydrate or caffeine withdrawals and therefore develop a headache. This is a temporary side effect and if you can, you might need to grin and bear it. Drinking the recommended amount of water can help, as your headache may be caused by dehydration. Failing this, a simple painkiller such as paracetamol can help.
Does The 1:1 Diet programme affect the menstrual cycle?
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.
Whenever I start The 1:1 Diet I feel nauseous. Is this normal?
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.
I have developed a rash. Am I allergic to Cambridge Weight plan?
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.
