Meal Replacement Diets & Weight Loss

Meal Replacement Diets Study - Aim
To evaluate the effectiveness of meal replacements (MRs) in weight loss
interventions in premenopausal women.
Meal Replacement Diets Study - Methods
Overweight premenopausal women (n = 113; body mass index: 25 to 35 kg/m2;
30 to 50 years old) were randomized into three interventions: group A,
a dietitian-led intervention; group B, a dietitian-led intervention incorporating
MRs; and group C, a clinical office-based intervention incorporating MRs.
In year 1, groups A and B attended 26 group sessions, whereas group C
received the same educational materials during 26 10-minute office visits
with a physician-nurse team. In year 2, participants attended monthly
group seminars and drop-in visits with a dietitian.
Meal Replacement Diets Study - Results
For the 74 subjects completing year 1, weight loss in the office-based
group C was as effective as the traditional dietitian-led group A (4.3
± 6.5 percent vs. 4.1 ± 6.4 percent), while group B maintained
a significantly greater weight loss (9.1 ± 8.9 percent; p <
0.02; mean ± SD). For the 43 subjects completing year 2, group
B showed significant differences in the percentage of weight loss (-8.5
± 7.0 percent) compared with group A (-1.5 ± 5.0 percent)
and group C (-3.0 ± 7.0 percent; p < 0.001).
Meal Replacement Diets Study - Issues
Study results showed that a traditional weight loss intervention incorporating
MRs was effective as a weight loss tool in the medical office practice
and in the dietitian-led group setting.

Weight Loss & Obesity Reduction
The science of weight loss and weight management is constantly evolving,
along with research into diet modification, types of gastrointestinal
weight loss surgery and weight loss drugs. At present, however, a balanced
diet plan combined with a regular fitness program remains the favored
weight control strategy of most weight loss experts. Return to Weight Loss Data
