Despite the expectations of the individual, the likelihood that an obese person will achieve sufficient weight loss to reach an 'ideal' body weight is remote (25). However, this does not imply that treating obesity is fruitless, as there is evidence that even a modest weight loss of 5-10% in obese diabetic subjects can produce clinical benefits. Improvements have been noted in all modifiable risk factors such as HbA1c levels, hypertension, dyslipidaemia, self-esteem and overall quality of life. Moreover, improvements in these risk factors have a favourable effect on mortality. A retrospective study of Type 2 diabetic patients receiving standard dietetic advice showed a mean weight loss of 2.6 kg for those with a BMI 25-30 kg/m2 and a loss of 6.8 kg for those with a BMI>30kg/m2 after 1 year. For the average patient each kilogram of weight loss was associated with a three- to four-month prolonged survival and a 10 kg weight loss predicted the restoration of about 35% in life expectancy (26).
