Weight loss and choosing a diet According to a recent study, an overweight adult adopting a plant-based diet is 15% more effective in losing weight than one on the traditional omnivorous (meat-eating) model. And it also finds that the effectiveness of a diet like this changes how much one loses.
Whatever the quality of their diet, the average vegan participant lost a little over 5.9 kilos (13 pounds).
The study employed three common indices. This allowed researchers to assess the value of a PDI, an uPDI, and hPDI separately.
The effects of a low-fat vegan diet on body weight, insulin sensitivity, and postprandial metabolism were also studied in terms of intramyocellula lipid (IMCL) levels among healthy adults with overweight or obesity. This was a secondary analysis of a randomized clinical trial (Trusted Source).
The trial used 244 overweight adults. Researchers assigned the twelve subjects to eat a vegan diet or stick with omnivorous eating habits. In the end, 223 participants finished the 16-week trial.
Otherwise, participants could eat what they wanted. Participants were asked to provide the researchers with three-day food records at baseline and week 16, respectively. They received no dietary advice.
As a result, all three plant-based indices increased throughout the trial period, and there was a strong relationship between weight loss and these scores.
The PDI had the largest negative correlation with body weight at a coefficient of -0.40.
We discovered a weak correlation of -0.21 between high uPDI scores and lower body weight, while higher hPDI scores revealed an even greater negative association with lower weights (- 0.37).
