Recent studies showed people
incorporating meal replacements are more likely to have adequate essential nutrient intakes compared to those following a more traditional food group
strategies that are both safe and effective are needed to reduce the rate of
the current obesity epidemic. A study published in the Nutrition Journal compared
the macronutrient and micronutrient levels in the foods chosen by women
following two different weight reduction programs.
generally healthy overweight or obese women were randomly placed into two treatment
groups: a Traditional Food Group (TFG) or a Meal Replacement Group (MRG). The MRG
included the use of 1-2 meal replacement drinks or bars per day. Both groups
aimed to restrict energy levels to approximately 1,300 calories per day. After
one year, weight loss was not significantly different between the groups, and
both groups had macronutrient (Carbohydrate:Protein:Fat) ratios that were
within the ranges recommended.
Both groups experienced
an improved dietary pattern with respect to decreased saturated fat, cholesterol,
and sodium, with increased total servings/day of fruits and vegetables. However,
the TFG had a significantly lower dietary intake of several vitamins and
minerals compared to the MRG and was at greater risk for inadequate intake.
groups successfully lost weight while improving overall dietary adequacy, the
group incorporating fortified meal replacements tended to have a more adequate essential
nutrient intake compared to the group following a more traditional food group diet.
This study supports the need to incorporate fortified foods and/or dietary supplements
while following an energy-restricted diet for weight loss.
