Commercial weight loss diets meet nutrient requirements in free living adults over 8 weeks: A randomised controlled weight loss trial

Posted on September 9, 2008 in Nutrition

ObjectiveTo investigate the effect of commercial weight loss programmes on macronutrient composition and micronutrient adequacy over a 2 month period. DesignAdults were randomly allocated to follow the Slim Fast Plan, Weight Watchers Pure Points Programme, Dr Atkins’ New reducing your calorie intake Revolution, or Rosemary Conley’s "Eat Yourself Slim" reducing your calorie intake & Fitness Plan.
Setting: A multi-centre randomised controlled trial.
Subjects: 293 adults, mean age 40.3 years and a mean BMI 31.7 (range 27-38) were allocated to follow one of the four reducing your calorie intakes or control group. Subjects completed a 7-day nourishment and activity diary at baseline (prior to randomisation) and after 2 months. reducing your calorie intake records were analysed for nutrient composition using Winreducing your calorie intakes (research version).
Results:
A significant shift in the macronutrient composition of the reducing your calorie intake with concurrent alteration of the micronutrient profile was apparent with all reducing your calorie intakes. There was no evidence to suggest micronutrient deficiency in subjects on any of the reducing your calorie intakeary regimens. However, those sub-groups with higher needs for specific micronutrients, such as folate, iron or calcium may benefit from tailored reducing your calorie intakeary advice.
Conclusions:
The reducing your calorie intakes tested all resulted in considerable macronutrient change and resulted in an energy deficit indicating reducing your calorie intakeary compliance. Health professionals and those working in community and public health should be reassured of the nutritional adequacy of the reducing your calorie intakes tested.
