It is not a matter of restrictive diets, but a matter of learning to eat properly. Customers are satisfied with the diets because they allow them to lose weight and also to eat more. The secret is in a good selection and combination of the food, and also in the evaluation of the nutritional status of the customer, so that his physiological, biochemical and metabolic needs may be covered by the intake of the food proposed in the diet. · Another important matter in the development of the company has been the continuous support to franchisers at the technical, commercial, marketing and administrative level.
