Possible temporary discomfort may be experienced during the first few days on the diet.

Headaches may occur due to insufficient fluid intake, change in caffeine intake or carbohydrate withdrawal. Increasing water intake should lessen these symptoms. You may also take your usual painkiller, such as aspirin or paracetamol. NB These symptoms are only temporary as your body adjusts to the new regime.

Bowel movements will be less frequent on the diet than on ordinary food and this is quite natural. However, if you tend to suffer from discomfort due to constipation drink even more water in the first instance. If problems persist, then you may need a fibre supplement Fibreclear (available from the clinic) or bisacodyl laxatives.
