Cambridge always recommend that you should consult your doctor before commencing any diet programme, but it is essential to get your doctor's signed confirmation of any medication or medical condition before you can start the 'Sole Source' programme, so that the doctor can adjust medication where appropriate.



Sole Source of nutrition

Step 1 is a nutritionally complete formula food (often referred to as a very low calorie diet, or the 'sole source of nutrition') which can be ideal for those who prefer a period of time away from the temptations of conventional food.

Sole Source is suitable for those above BMI 25, with at least 6.3kg to lose.
On this programme, the dieter takes two-three SoyaSlim® meals in place of conventional food. For men, or women above 1.7m, three SoyaSlim® meals should be taken. In addition to water used to mix the diet powder and cups of unsweetened black tea or black coffee, it is advisable to drink at least 2 litres of water per day.

Using the 'Sole Source' programme is not advisable when certain medical conditions are present. We say these conditions are 'contra-indicated'. There are also a number of medical conditions with which 'Sole Source' may be used with special precautions.

Cambridge recommends that the Sole Source programme is followed for no longer than four weeks at a time. At that point, if target weight has not yet been reached, the dieter should have an 'Add a Meal' week.

Step 1 Add-a- Meal

This variation of 'Step 1 Sole Source' is most suitable for those, who might find it difficult to stay on Sole Source due to their lifestyle or type of work.

The ‘Add a Meal’ menu is also used as a natural break after four weeks on Sole Source, and is also the first part of the stabilisation process once target weight is achieved. Sometimes referred to as the ‘green and white’ meal, this menu introduces selected lean protein and vegetables to supplement the Cambridge meal options.

• 2 or 3 SoyaSlim® meals
• 80g portion of white fish
• 80g poultry meat (without skin or fat)
• 80g tofu
• 80g skimmed milk cottage cheese
• 2tbsp ‘white or green’ vegetables (cooked or raw) such as spring greens, cauliflower, lettuce, mushrooms, cabbage, broccoli, celery, cress, zucchini or cucumber.

Continue to drink at least 2 litres of water per day, and as much unsweetened black tea or black coffee as you want.
