Calculate you BMI

Being overweight or obese is one of the major health hazards facing us today. Being obese can take up to nine years off your life. It also makes you far more likely to develop a range of health related problems.

There are a number of ways to work out if your weight is putting your health at risk. Two of the most popular and reliable indicators are your Body Mass Index (BMI) and your waist measurement.

What your BMI means

BMI below 20 = Underweight
You are underweight for your height and your health could be at risk. You do not need to be on a weight loss programme. Talk to your doctor or health professional about how you can reach a normal weight.
BMI 20 - 25 = Healthy weight
Well done, you are an ideal weight for your height.
BMI 25 - 30 = Overweight
Your weight is above the ideal range for your height and your health could be at risk.
BMI 30 - 39 = Obese
Your weight is increasing the risk of heart disease and other serious medical conditions and you need to take action.
BMI 40+ = Very Obese
You are seriously at risk of heart disease, stroke and premature death, take action now.

Want to achieve your ideal weight? Who should I talk to?

If you want to achieve your ideal weight, contact us at Enosis and we will  be able to advise you on how to select a Cambridge Weight Plan programme to suit you.

How do i get started?

The first step to losing weight is to contact an Enosis consultant who is trained and accredited by the Company. In your first meeting we will weigh and measure you and then discuss the range of Cambridge weight management programmes available. Together we will decide which programme best suits your lifestyle and dieting needs – a major factor in maintaining motivation and achieving long-term success.

Please note:

We recommend that you should always consult your doctor before commencing any diet programme, but, with the Cambridge Weight Plan it is essential that you get your doctor’s signed confirmation of any medication or medical condition before you can start any Cambridge programme. Your Consultant will explain this when you visit them for the first time. This is a requirement; your doctor might, for example, want to adjust your medication where appropriate as your weight reduces.

All our consultants are accredited after a period of training. The Cambridge Weight Plan is not available to purchase in shops, over the internet or in any other retail environment.

If you would like to discuss this with one of our staff, please call 1800 366 747.

PRODUCT FAQS: Using the Plan

How much water do I need to drink?
It is very important to consume at least eight glasses of water or other liquid per day. It is very important that we constantly replace our body fluids. Sufficient liquid intake is also necessary to maintain proper kidney function.
Why must I drink so much?
A good rule of thumb for good health is to drink 4pt (2.25 ltr) of fluid a day whether trying to lose weight or not.

PRODUCT FAQS: Diet Products

Does the Cambridge Weight Plan contain enough protein when taken as a sole source of nutrition?
The research undertaken to develop the Cambridge Weight Plan showed that protein and carbohydrate provided by the diet were sufficient to maintain lean body tissue.
Is Cambridge suitable for vegetarians?
The items in the range which are not suitable for vegetarians – Chicken and Mushroom Soup which uses chicken in the flavouring and Strawberry Silk, which uses cochineal for colouring.

Strict vegetarians will be reassured to know that non-animal rennet is used in Preparation of the whey protein in the Cambridge Weight Plan meal bars.

Vegans, who do not use or consume any animal products including dairy products could use Cambridge Fibre, Golden Vegetable drink flavouring, and the water flavourings would also be suitable. All other products would be unsuitable.

Why should you not use three Cambridge Bars a day while on Sole Source?
There is more carbohydrate in the bars than in the drinks and soups. Three bars in a day can contain enough carbohydrate to break the mild ketosis which you get on ‘Sole Source’. Without this ketosis, you could become hungry and uncomfortable and so less likely to remain on the ‘Sole Source’ programme.

For some people, even one bar a day can prevent ketosis.We recommend that only drinks are used during the first two weeks on the ‘Sole Source’ programme. A simple urine test for ketones can help with a customer who is experiencing poor weight loss on two drinks and a bar – sometimes the extra carbohydrate causes fluid retention. A warning: the complex carbohydrate in the bars can cause flatulence in some people. One a day does not usually cause a problem, more could be socially embarrassing.  

MEDICAL FAQS: Side Effects

Why do I get a headache on Sole Source?
Occasionally, during the initial three days a person may experience carbohydrate withdrawal and may develop a headache. This is a temporary effect and should be tolerated. A simple tablet for headaches, for example paracetamol, taken for a day or two will improve the problem. Insufficient fluid intake could also cause a mild dehydration, and ensuing headache. Ensure that the recommended amount of water is drunk.
Just after starting Cambridge, I suffered from diarrhoea. Why is this?
This is a minor problem and is considered a possible transient effect that will last for only a short time. Some people have systems that are not used to the mineral content in the Cambridge Weight Plan is a good idea to drink an extra glass of water with the Cambridge Weight Plan meals, which will dilute the effect of the minerals in the body. The solution is to take the Cambridge Weight Plan in the form of mini meals (six half portions per day) initially to slow 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. If this is the case, we have a range of lactose free products that could be used instead.
Is it normal to experience euphoria on Sole Source?
This is very normal and should not cause any concern. In fact, why not just enjoy it!
Why am I having trouble getting the normal amount of sleep?
It is not uncommon for a person to require less sleep when they lose weight. . There are many cases where people thought that they required 9 or 10 hours of sleep per night, only to find that when they lost weight their sleep requirement dropped considerably. Having an extra hour or two awake each day may be a pleasant side effect of the Cambridge Weight Plan.
I feel thirsty sometimes. Is this normal?
It is normal to experience thirst on occasion when dieting. The solution is simple. Drink more liquids. We recommend that users of the sole source programme drink 2.25 litres [about 4 pints] of water each day. That is 9 to 13 glasses or tumblers full depending on whether the glass volume is 175ml or 250ml. This 2.25 litres is the sum of 1.2 litres (being the Food Standards Agency recommendation for fluid intake) plus the water content of food items not being consumed (usually about 1 litre, but could be up to 2 litres). There is probably very little benefit to be gained from consuming more than double our recommendation [double our recommendation would be 4.5 litres].
I notice a tendency towards bad breath. Why is this?
A mild ketosis may develop when on the Cambridge Weight Plan as your sole source of nutrition and this may affect your breath slightly. Simply brush your teeth more often, and use mouth wash, sugar-free chewing gum or breath fresheners.
Is it normal to get constipated after starting Cambridge?
The Cambridge Weight Plan contains sufficient roughage for most people. When one goes on any diet including the Cambridge Weight Plan, much less bulk is being consumed, and therefore there is much less bulk to be eliminated. As a result, bowel movements are much less frequent. This is normal, and should not cause immediate concern. However if constipation persists for more that three days, or if physical discomfort is being suffered, an over the counter laxative should be obtained from the chemist, and taken according to instructions. Psyllium containing laxatives have been found to be particularly effective.
Whenever I start Cambridge I feel nauseated. Is this normal?
Some people have more sensitive stomachs than others and such individuals may sometimes develop nausea when they first consume Cambridge Weight Plan products. Often a full glass of water following your Cambridge meal will eliminate this problem.

Another solution is to break the Cambridge Weight Plan down into six mini meals per day, and follow each meal with a glass of water to dilute the effect of the minerals.

Why did I feel dizzy a few days after starting Sole Source?
Dizziness is a possible transient effect of any diet and should only last for a day or so. It is often caused by the diuretic effect that accompanies any low calorie diet. During the first few days of the diet, the body will excrete a considerable amount of water, which then requires readjustment of the fluid content of different parts of the body. It is important to drink the recommended amount of liquid and avoid quick changes in position and extreme exertion during the first few days of the Diet.
Why do I feel cold on the Cambridge Weight Plan Sole Source 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.


I am being treated for depression. Can I take Cambridge?
That would depend on the particular medication that you have been prescribed. It is important to have the support of your doctor and/or psychiatrist.

There would almost certainly be a Cambridge programme that you could follow.

I am on a low sodium diet. How much salt does Cambridge contain?
The Cambridge Weight Plan contains approximately 500 mg of sodium per serving, or approximately 3.8g [three Cambridge products] salt per day. A doctor should be consulted if the dieter has been placed on a low sodium diet, to make sure that the sodium intake is not in excess of the doctor.


Why are pregnant or breast feeding women advised not to use Cambridge? 
Pregnant and lactating women require increased levels of protein and energy, and are advised to follow a diet rich in lean protein, wholegrains fresh fruit and vegetables etc.
Will the Cambridge Weight Plan bring on ketosis?
The Cambridge Weight Plan is specifically formulated with 44 grams of carbohydrates in addition to the protein and fat present. This combination produces a mild ketosis which can be a benefit to those on weight-loss programmes as it may give a feeling of euphoria in some people while curbing the appetite.
Does the Cambridge Weight Plan affect the menstrual cycle?
Rapid weight-loss with very low calorie diets may temporarily affect the menstrual cycle patterns; ovulation, however is probably not interrupted. The metabolism of contraceptive pills may be affected during effective weight loss so extra care may be needed.
I have had a heart attack. Can I take the Cambridge Weight Plan?
Check with your doctor before going on any diet. The Cambridge Weight Plan is low in Cholesterol, low in sodium and low in fat, and is suitable for weight loss after full recovery.
I have had surgery for cancer. Can I take the Cambridge Weight Plan?
There are no specific contra indications to using the Cambridge Weight Plan after surgery for cancer provided that full wound healing has occurred and the medical and surgical teams approve of the intention to lose weight. You must consult those who know you case in detail.
Do I need my doctor’s consent to use the Cambridge Weight Plan with food?
We would recommend that anyone wishing to follow any weight loss programme at any calorie level should check with their doctor first. All Cambridge Weight Plan customers need to complete a Medical Record Form whether they plan to use the diet with or without food. Anyone on prescribed medications or with a medical condition and planning to use the Diet at less than 1500 Kcal per day should also consult their doctor.
My doctor says I am clinically obese and that losing weight would improve my general health. My Consultant insisted on my doctor signing the Medical Record Form. Is this correct?
We recommend that all customers, even those in perfect health, should consult their doctor before starting any weight loss programme, particularly if a doctor has not been consulted during the previous 12 months. Obesity is a significant factor in a number of medical conditions and anyone who is obese may have developed a medical condition of which they are unaware of. In the case of anyone who is on prescribed medication, or is suffering from a medical condition, the consultant will ask for the doctor’s signed confirmation that the information given on the Medical Record Form is correct.
I have diabetes and my condition is controlled by diet. Must I see a doctor before going on the Diet? 
Yes. Nobody with diabetes should attempt to lose weight without being supervised by his or her doctor. The Cambridge Weight Plan programmes are not usually used for patients with type 1 diabetes (insulin requiring) or type 2 diabetes (usually treated with diet and/or oral drugs) when they require insulin, except in specialist units with tight supervision. The customer must have the full agreement off their doctor or health care professional to say that they are willing to adjust medication and monitor the customer throughout the weight loss process. Again, adopting the maintenance programme is a good long-term health strategy.
What is ketosis and is it harmful?
When fat is released from fatty (adipose) tissue it travels to the liver where it can be used to make more fat or be ‘burned’ producing energy. The energy production pathway produces ketones. Everyone has some ketones in their blood at all times, but usually at low levels. The levels rise when fasting or while on a low carbohydrate diet designed to induce ‘ketosis’. ‘Ketosis’ is a term applied to a state where the ketone blood levels are high enough to allow ketones to leave the body on the breath or in urine. Physiological ketosis is a normal protectic mechanism reflecting the way in which the body switches its metabolism to ‘burning fat’. The effect of high levels of ketones varies from person to person. Some people feel euphoric, others may not feel hungry. There is little evidence that physiological ketosis is harmful.
What is the ketone test?
This is a simple urine test which indicates the presence of ketones.
What is metabolic rate and can it be damaged by rapid weight loss? 
The weight and amount of lean (muscle) tissue of the body are the major determinants of metabolic rate. The human body evolved to be super efficient in conserving energy. When dietary energy intake goes down the body adapts by reducing heat and energy loss thus metabolic rate drops. After weight loss and the establishment of a new lower energy requirement metabolism of the body should return to a level appropriate for the new amount of body weight and lean tissue.
I am using the Sole Source programme, but have a cough and cold – what can I take?
The diet contains all the nutrients required for normal health but when you a fighting an infection you may do this more effectively on a higher energy intake. While you recover you should raise your energy intake to a higher level. Remember that cough and cold remedies often contain sugar so you may want to choose sugar-free versions. 
Is it all right to continue the Sole Source programme if giving blood?
The Sole Source programme should not be followed for one week preceding blood donation and for one week after. During this time it would be wise to raise energy intake levels up to 1000kcal/d.

MEDICAL FAQS: General Nutrition

Why do you always advise people to consult their doctor before starting any weight loss programme?
There are two reasons: If it is some time since you last saw your doctor, you should have a check-up before starting a weight loss programme. Based on the results of this check-up and on your medical history, your GP can advise you on a suitable weight loss regimen. Obesity can be a contributing factor in some medical conditions.
What are the ingredients used and the nutritional information?
What should I consider before starting The Plan/Contra-indications?

Medication and medical conditions

For the purposes of weight loss using the Cambridge Weight Plan, four categories have been identified for medications and medical conditions.

A.    Contraindicated – You cannot use ANY programme

Medical Conditions:

  • The Cambridge Weight Plan should not be used in any weight loss programme by the
  • following people:
  •  Pregnant or breast-feeding women
  • Children under 14 years of age
  • People who have had a heart attack, stroke, an operation or serious accident within the last three months.
  • Anyone with a serious heart condition
  • Anyone with Porphyria
  • Anyone with severe kidney or liver disease
  • Anyone with severe depression
  • Anyone with anorexia or bulimia nervosa


Anti-Obesity Drugs (prescribed or available over the counter).
It is unnecessary for these drugs to be taken when a Cambridge weight-loss programme is being followed. If you remain on these drugs, then the Cambridge Weight Plan must not be used.

B.    Not Low Calorie – You can only use programmes above1200kcals per day

Anyone taking any of the following medications should not follow the Cambridge Weight Plan Sole Source®, Sole Source Plus®, 810kcal or 1000kcal programme.

  • Anti-coagulants
  • Anti-arrhythmia drugs
  • Anti-convulsants
  • Lithium


Anti-coagulants, anti-thrombotics and fibrolytics all reduce the clotting time of blood. They are frequently prescribed following open heart surgery, heart attacks, deep vein thrombosis and arterial thrombosis. Anti-arrhythmia e.g. Digoxin

These medications are used to correct irregularities in the heart rate associated with heart failure. The blood levels of these medications are normally difficult to balance. A reduced calorie intake could increase this instability by allowing more rapid absorption.


Anti-convulsant drugs are used to treat epilepsy and seizures.


Lithium is used to treat severe psychiatric disorders. A reduced calorie intake will increase the absorption rate of this drug and this may alter the blood levels of Lithium.
As a constant level is essential for successful treatment and to prevent toxic effects occurring, it should not be used with the Cambridge Weight Plan.

C.    Special Precautions – You can use any programme, although your doctor may need to adjust medication

Because of the low calorific level in the Cambridge Weight Plan, people taking certain medications may need their doctor to adjust the dosage level. In some cases, the doctor may need to discontinue medication completely. Customers in this group should have their progress monitored by their doctor.
Every customer taking one of the medications which falls into the ‘Special
Precautions’ category must get the doctor’s signature of confirmation on their
Medical Record Form (MRF). The Consultant should ask the customer to remind the doctor to note on the form the name of the medicine being taken.


Anti-hypertensive drugs are used to reduce all grades of raised blood pressure. This group includes beta-blockers, ACE inhibitors, calcium antagonists, vasodilators, alphablockers, central alpha antagonists.


Diuretics (water tablets) are frequently used for the treatment of mild to moderate high blood pressure (hypertension). It is advisable for the doctor to reduce or stop diuretic medication before the Cambridge Weight Plan is started.

Gout prevention

All VLCDs produce a rise in serum uric acid levels during the first two weeks, which may lead to an acute attack of gout in known sufferers. Preventative treatment with one of the uricosuric agents should be given concurrently with the Cambridge Weight Plan from the day of commencement.

C. Special Precautions (Diabetes)

There is a separate protocol for customers with diabetes; your Consultant should refer to it in your initial appointment.

D.    Other Medication – You can use any programme

All other medications can be used with all the Cambridge weight-loss programmes. However, Consultants should still get the customer to ask for their doctor’s signed confirmation that the information stated on the MRF is correct.


Severe depression is a contra-indication for all programmes. Any customer without severe depression who is on anti-depression medication needs to have their MRF signed by their doctor before they can start.

Thyroid and Anti-Thyroid medications

The medications are designed either to replace deficient thyroid hormones or to block thyroid hormone production; we do not distinguish between the two. However, it is sensible for the person to have been on these medications for at least two months or more before they begin using the Cambridge Weight Plan, in order to allow the medication levels to settle. Thyroid control does not have to be perfect.


Although these may be taken in conjunction with the Cambridge Weight Plan customers may experience a lower rate of weight loss.


These are known as NSAIDs (non-steroidal anti-inflammatory drugs) and are widely prescribed for the treatment of rheumatoid and osteo-arthritis, gout, rheumatic pain, sports injuries and general aches and pains, customers taking these medications may use the Cambridge Weight Plan programmes.


Antibiotics are prescribed to treat all kinds of infection, from bronchitis to a septic finger. Always check the underlying medical condition – anyone with a serious infection should not be contemplating weight loss until they are fully recovered.

The doctors signature on the MRF is not required for the following:- Contraceptives:

The Pill
The contraceptive pill is used to prevent conception. They are almost always prescribed under their trade names and most women are well aware if they are taking one of them.

The Cap
Women using the contraceptive cap should be advised to see their family planning advisor every time there is a weight change of 3kg (7lbs) to check whether a different size is required.

Hormone Replacement Therapty (HRT)

HRT is widely used for the relieve of menopausal symptoms, in these cases the customer may use the Cambridge Weight Plan without a Doctors signature, however it is sometimes given to treat more serious conditions, such as breast, kidney or prostate cancer. In such cases it is absolutely essential to consult the doctor and get his or her signature of approval on the MRF. If in doubt, insist on the doctor’s signature.
