[The work of the dietician in the outpatient obesity unit].

The dietitian plays an important role in the care of obese patients. The dietitian evaluates 7 day food records and according to the individual composition of the diet gives dietary advice to the patient. The energy content and macronutrient and micronutrient composition is only one aspect of dietary counselling. Knowledge of patient's familial and economic status as well as his usual eating pattern, his tastes and capabilities of person who does the shopping and cooking are necessary before the diet can be recommended. The balanced energy-restricted diet is used, predominantly with reduction of the fat intake. Energy expenditure in individual patients is considered when the diet is planned. The regular controls by a dietitian are essential in the long-term treatment of obesity.
