title: Nutritional adequacy of energy restricted diets for young obese women.
abstract: OBJECTIVE
  Energy restricted meal plans may compromise nutrient intake. This study used diet modelling to assess the nutritional adequacy of energy restricted meal plans designed for weight management in young obese women.
  
  
  METHODS
  Diet modelling of 6000 kJ/d animal protein based meal plans was performed using Australian nutrient databases with adequacy compared to the Australian Nutrient Reference Values (NRVs) for women (19-30 years). One diet plan was based on the higher carbohydrate (HC) version of the Australian Guide to Healthy Eating for women 19-60 years. An alternative higher protein (HP) plan was adapted from the CSIRO Total Wellbeing Diet. Vegan and lacto-ovo versions of these plans were also modelled and compared to the appropriate vegetarian NRVs.
  
  
  RESULTS
  Both animal protein diets met the estimated average requirement (EAR) or adequate intake (AI) for all nutrients analysed. The recommended dietary intake (RDI) was also satisfied, except for iron. HC met 75±30% and HP 81±31% of the iron RDI when red meat and iron fortified cereal were both included three days a week, and remained below the RDI even when red meat was increased to seven days. Iron for the modified vegan (57±5% HC; 66±4% HP) and lacto-ovo (48±6% HC; 59±7% HP) plans was below the RDI and zinc below the EAR for the vegan (76±8% HC; 84±9% HP) plans.
  
  
  CONCLUSIONS
  The 6000 kJ/d animal protein meal plans met the RDI for all nutrients except iron. Iron and zinc failed to meet the vegetarian RDI and EAR respectively for the vegan plans.
