What is the Cambridge Diet
The Cambridge Diet is a nutritionally complete formula food. It can be used for weight loss and to help with weight maintenance. Many people use it for nutritional assurance too. There are over 15 flavours of Diet. These are produced in the form of a milkshake, soup, meal bar or a ready-made tetra-brik drinks. When used for weight loss the Diet can be utilised alongside conventional food once or twice each day or it can be used to replace all usual food intake. The number of calories taken each day would range from 411 - 1500kcals.

Which is the best Cambridge programme to use?
This really depends on you, as successful weight loss can be achieved on all of the programmes. The secret is to match the programme that will fit in with your lifestyle. For example if you really look forward to your evening meal with the family the 1000kcal or 1200kcal programme (where you would take two Cambridge servings each day alongside a balanced meal) may be your preference. On the other hand you may be the sort of individual that would find it much easier to remove all food choices during the weight loss period. If this were the case then the sole source programme - where all usual food is removed and no decisions have to be made - would be ideal for you. Again the sole-source programme is ideal for those who don't want to feel hungry during the weight loss phase.

How long can I stay on the diet?
You can stay on the weight loss programme for as long as you have excess weight to lose. If you had used the sole-source programme for weight loss you would start to add additional usual food when you have reached BMI 26.

How much weight will I lose?
This depends upon the programme you select. You would expect to see approximately 6-7 pounds of weight lost over a four-week period if you were on the 1000kcal programme. If you were on the sole-source programme it would be at least one stone.

What does sole-source mean?
Sole-source means you are eating the diet and nothing else - in other words the diet is the sole-source of your nutrition.

I have heard that if you lose weight fast then you put it on even faster
This is a myth. The only reason weight loss will not be retained is if you eat more than you should at the end of the weight loss period. Remember for every stone you lose you will need to eat approx 150kcal a day less than before you started. Use a smaller dinner plate!

Will I be able to retain my weight loss?
Yes you definitely can retain the weight loss. To ensure this happens make a serious commitment to understand the changes necessary for long term success before you start on the weight loss programme!
If it isn't the right time then concentrate on using a Cambridge programme to help with weight maintenance until you are ready. The Cambridge programmes are structured so that advise and support from you counsellor will be with you as you wean off the Diet and learn the new habits that are needed to achieve long term weight management success.

I am a vegetarian can I use this diet?
Yes - the only exception is the chicken and mushroom soup, which contains real chicken in the flavouring. There are various types of vegetarians, some with a stricter outlook than others. Non-animal rennet is used in the whey protein in the Cambridge meal bars so they are suitable for strict vegetarians. Strict vegans who shun all dairy products will not be able to use Cambridge Diet products.

Do you just stop the diet?
All of the Cambridge programmes follow a structure. So when you have got to where you want to get to or if you wish to have a break during the weight loss phase your Counsellor will advise you how to wean off the programme that you have been on.

Whichever programme you have used for weight loss it is followed by a structured stabilisation, weight maintenance and long-term weight care plan. This is done over a period of a few weeks, where you will gradually increase your intake of usual food whilst removing a Cambridge diet serving. If you have been following the sole-source programme then an additional re-feeding step is incorporated, before the stabilisation phase, to prevent glycogen rebound.

Will I have to take the product for ever?
No. You will be shown and encouraged to develop new eating habits. However many people choose to use a Cambridge products each day as a tool to help with weight maintenance. But the choice is yours.

How do I work out my BMI?
This is a figure calculated from you height and weight (metric weight ÷ metric height˛). So if you are 6ft tall and weigh 100kg you would be BMI 30. A healthy BMI is between 20-25. A BMI above 30 is classed as obese.

Will I need vitamin supplements whilst using the diet?
The big plus about Cambridge is that, unlike other diets, you do not need to take extra supplements. Each item offers a third of the recommended daily allowance of all vitamins, minerals and trace elements, so three a day give complete nutrition. The main worry when people go on food-based slimming diets, is that reduction in food means reduced nutrient intake which in turn puts health at risk. It is impossible to achieve complete nutrition from conventional food on less than 1500 Calories a day. Even then, extensive nutritional knowledge and a wide variety of foods need to be consumed to ensure adequate intake of all those vitamins and minerals.

Cambridge has cracked that problem by formulating a diet that gives 100% nutrition. Cambridge customers have confidence that they can lose weight safely and not put health at risk. No wonder so many people feel so good while taking Cambridge!

Could I become addicted to the diet?
No there are no drugs in the product just 100% complete balanced nutrition - although many people continue to take it as they say they have never felt so well as when they are using it!

What are carbohydrate foods?
Bread, potatoes, pasta, rice, cereals, fruit and vegetables are all healthy sources of carbohydrate and fibre. Sugar and alcoholic drinks are all poor sources, of little nutritional value and pure indulgence!

Unrefined and complex carbohydrates (starches) such as wholemeal bread and brown pasta have a higher nutrient value than refined carbohydrates. To produce refined carbohydrate, eg. white sugar or white rice, the manufacturer uses a process which actually removes a large percentage of the food's fibre content, and also causes a loss of other nutrients such as vitamins and minerals.

Starch is the optimum source of energy and should always be eaten in preference to sugars. Experts believe that carbohydrates should make up approximately 55% of a healthy diet.

Do I have to exercise whilst on the diet?
We would always encourage people to increase their activity levels. This helps to increase muscle mass and muscle tone, is beneficial to health and helps with weight maintenance. The emphasis is on activity i.e. increase is walking or playing sports. It also helps aid weight maintenance.
