Reviews of these reports and journals were conducted by a pair of reviews independently and in duplicate to extract the relevant information specifically pertaining to factors like demographic information, experimental and control intervention, degree of calories and behavioral support. The dietary treatment groups were categorized in two ways diet classes and diet brands. The diet akin LEARN was considered having full form Lifestyle, Exercise, Attitudes, Relationships and Nutrition as a kind of care comparator which was based on popular program among health professionals emphasized on behavioral modification and adaptability.
Analyses were conducted on data of 6 to 12 months having a window of 3 months. The network meta-analysis of each diet was connected through density and the number of pair of treatments. The pairwise random effect meta-analysis were used for determining the direct and indirect treatments associated with the analysis (Appelhans, 2013).
The data of 12 months assessment showed results of the quality evidence when the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used. For direct and indirect comparison, initially there was high confidence level in context of estimates but later on the data with 6 month assessment rated down to moderate and low based on the risk of biasness and inconsistency.
Results
The total of more than 20,000 unique titles had been identified as original publications out of which 889 proved to be potentially fully relevant along and thereon 59 articles reported 48 RCTs of 11 branded diets finally got eligible. These 48 RCTs included more than 7,000 individuals with median age of 45 and weight of 94 kg having BMI of 33.
Out of this data, it was found that among the all diet classes the moderate macronutrient and low-carbohydrate diets were the most common within which Atkins, Weight Watchers and Zone were the top brands having most of the comparisons. The network meta-analyses were connected with the parameter of density, which resulted 1.0 and the 6, and 12 month brand network assessment had densities of 0.36 and 0.47 respectively. The analysis for diet class resulted that all treatments were superior to no diet at 6 month checkup plan and low-fat diets had similar estimated effects. The analysis of 12 month follow-up plan estimated average loss of weight of all diet classes when compared with no diet resulting in loss of 1 or 2 kg lesser than 6 month follow up plan. With the 6 month follow-up the low-carbohydrate diet class estimated the highest treatment effect and resulted superior to all other diet classes.
Discussion
Out of 48 original RCTs which were included in network of our meta-analysis, there is low evidence of quality data regarding the fact that both low-carbohydrates and low-fat diets are associated with an estimate of 8 kg loss of weight at 6-month follow-up as compared to no diet whilst only 1 or 2 kg of extra loss of weight had been observed with data of 12 months follow-up.
The data support the recommendations that most
