Losing weight is probably the easiest part of the weight management process. Having chosen the day, look forward to it with pleasure. Try and stick to the chosen Cambridge programme and the menu.

Sole Source (Step 1)
On the Sole Source programme, you will have three (or four if you are a man or above 176cm/5ft 8in) Cambridge meals every day – and no other food! You should also drink plenty of water (we recommend at least eight glasses per day). The first few days will be exciting, as you lose weight every day. It is highly motivating to continue. You will feel better and healthier than you have ever felt in your life because your body is receiving everything it needs.

You may feel hungry during the first three days, particularly during the evening. Either do something to keep your mind very occupied or go to bed early with a good book (or partner!). After a few days you will not feel hungry at all. Remember that if you do eat you will feel very hungry, because any extra food will stimulate your appetite. Make a commitment to lose weight and be determined!

Allowed fluids:
black tea or coffee,
tap or bottled water, which can be ‘still’ or ‘sparkling’, but should not contain fruit flavouring

Forbidden fluids:
alcoholic beverages, milky tea or coffee, pure fruit juices and any drink containing sugar or calories.

First Weeks
After a few days you will not feel hungry at all. In fact, you'll feel wonderful. But losing weight can be frustrating and your Cambridge Counsellor can be a great help and may make the difference between success and failure. If you have any problems or want advice, it is part of the Counsellor’s job to help you.

You can indulge in all your normal activities but you don't overdo it. If you feel tired, then take a rest. You should weigh yourself every day at the same time, usually in the morning. You will be delighted with your progress and be very excited with it. This is the real motivation that makes you want to continue.

You may experience several days when you do not lose weight. Do not become discouraged. It is very likely that you are losing fat but retaining water; this is a process known as plateauing. You may be losing girth faster than weight, which is why we recommend that you use a tape measure to record your vital dimensions in addition to your weight.

Have faith in the diet because the weight-loss will restart once you lose the water you have been retaining.
