Use of meal replacements (MR) and physical activity (PA) seems to be effective weight-loss strategies both in the short and
long term in a clinical trial setting.
Two longitudinal studies kept track of the nutritional parameters development within the weight loss programs based
mainly on low-calorie diet using MR (MR group, 56 women and 23 men) and physical activity (PA group, 97 women and 46
men). In both samples, weight loss was significant, with an average of-10 to 11% of initial weight, but in different periods of time
(on average 4 months to MR sample and 9 months to PA sample).
The average weight loss was -2.7 kg/month in MR group and -0.8 kg/month in PA group, with higher values in men for
both study groups. Percentage of excess weight loss was approximately 40%, and adherence to weight loss program was better for
women in MR group and for men in PA group. The percentage of weight loss was significantly correlated with the length of weight
loss program, but also with initial BMI. Replacing two meals a day was an effective way to lose weight because of its simplicity and
convenience of use. The cost of the products and monotony of the diet were the main causes to abandon the diet.
Subsequently, keeping the obtained weight was better in the subjects replacing one meal a day with MR and in the people
keeping a high level of PA.
