Almond intake significantly reduces body weight and fat mass in adults, yet it does not impact body mass index, waist circumference, or fat-free mass.
The methodology used in this study started with a comprehensive search of online databases including PubMed, Scopus, ISI Web of Science, Cochrane Library, and Google Scholar until January 2020. The goal was to identify relevant randomized controlled trials for inclusion, which led to the discovery of 28 trials among 2983 reports, that were deemed suitable for analysis. The data were reported as weighted mean differences and standard deviations to signify the impact of almond consumption on different bodily measures including body weight, body mass index, waist circumference, fat mass, and fat-free mass.
As for the results, pooling of data was done utilizing a random-effects model, the outcome of which indicated a significant reduction in body weight and fat mass following almond intake. However, no meaningful change was found in measures of body mass index, waist circumference, or fat-free mass as a result of almond consumption. Interestingly, such intake showed a significant influence on weight and fat mass reduction, with no observable effect on the other parameters examined.
